Thus, 4.0 moles of NH3 would be produced when 6.0 moles of H2 react with sufficient N2.
Suppose 6.0 mol of H2 reacts with sufficient N2 to produce ammonia, NH3. We can determine the number of moles of NH3 produced using stoichiometry.The balanced chemical equation for the reaction is:[tex]3H2(g) + N2(g) → 2NH3(g)[/tex]
From the equation, we can see that 3 moles of H2 react with 1 mole of N2 to produce 2 moles of NH3.
Therefore, using the mole ratio from the balanced equation, we can calculate the number of moles of NH3 that would be produced when 6.0 mol of H2 reacts with [tex]N2:6.0 mol H2 × (2 mol NH3/3 mol H2) = 4.0 mol NH3[/tex]

If the anticipated claim outcome actually occurs, it will be feasible to get in touch with the entity once more; if it isn't, both crucial systems will undoubtedly miss the statement.
Here,
We must first determine how much is deducted from Claire's gross salary annually for the 401(k) plan in order to determine
how much money is deposited into her retirement account by her employer each month.
Since we are aware that Claire contributes 5% of her total income to her 401(k),
we can figure out how much she contributes as follows:
=> 0.05 x $92,400 = $4,620
As a result, Claire's 401(k) plan deducts $4,620 from her total income each year. We can reduce this amount by 12 (the number of months in a year) to determine how much it is per month:
=> $4,620 ÷ 12 = $385
As a result, Claire's employer contributes $385 each month to her 401(k) savings account.
Therefore, choice (B) $385 is the correct response.

Answer: 131.95 cm
Step-by-step explanation:
The diameter of the semicircle is 42 cm, which means the radius is half of that:
r = d/2 = 42/2 = 21 cm
The circumference of a full circle with radius "r" is given by the formula:
C = 2πr
Since this is a semicircle, we need to divide the circumference by 2:
C/2 = πr
Substituting the value of "r" we found above, we get:
C/2 = π(21)
Simplifying:
C/2 = 21π
C = 2(21π)
C ≈ 131.95
Rounding to the nearest hundredth, we get:
C ≈ 131.95 cm
Therefore, the circumference of the semicircle is approximately 131.95 cm.
How much will a new TV be worth now if it depreciates by 9% each month, and you bought it new 8 months ago for $2740?
Give your answer to two decimal places.
How much it's worth after 8 months =$
Answer:
To find out how much the TV is worth now, we need to apply the depreciation rate of 9% to the original price for 8 months:
First, let's calculate the value after the first month:
Value after 1 month = $2740 - (9% of $2740) = $2501.40
Now, let's calculate the value after 2 months:
Value after 2 months = $2501.40 - (9% of $2501.40) = $2275.80
We can continue this process for 8 months to find the current value:
Value after 3 months = $2071.67
Value after 4 months = $1888.81
Value after 5 months = $1725.10
Value after 6 months = $1579.92
Value after 7 months = $1452.16
Value after 8 months = $1339.53
Therefore, the TV is worth $1,339.53 now.

25 buses are running between two places P and Q. In how many ways can a person go from P to Q and return by a different bus
There are 300 ways a person can go from P to Q and return by a different bus.
To find the number of ways a person can go from P to Q and return by a different bus, we can use the combination formula:
nCr = n! / (r! × (n-r)!)
where n is the total number of options, and r is the number of choices we want to make.
In this case, there are 25 buses running between P and Q, so the total number of options for going from P to Q and returning by a different bus is 25 × 24 (since we have 25 choices for the first leg of the journey, and 24 choices for the second leg).
To find the total number of ways to make this choice, we can use the combination formula with n = 25×24 and r = 2
nCr = (25×24)! / (2! × (25×24-2)!)
= (25 × 24)! / (2! × 23!)
= (25×24) / 2
= 300

the radius of a sphere decreases at a rate of 3 m / s . find the rate at which the surface area decreases when the radius is 8 m . answer exactly or round to 2 decimal places.
The rate at which the surface area of the sphere is decreasing when the radius is 8 meters and decreasing at a rate of 3 m/s is approximately -192π square meters per second.
Let's start by finding the formula for the surface area of a sphere. The surface area (A) of a sphere with radius (r) is given by the formula:
A = 4πr²
Now, we need to find the rate at which the surface area is changing with respect to time (t) when the radius is 8 meters and the rate of change of radius is 3 m/s.
To find dA/dt, we need to differentiate the formula for surface area with respect to time, using the chain rule:
dA/dt = d/dt (4πr²) = 8πr (dr/dt)
Here, we have used the fact that the derivative of r² with respect to time is 2r (dr/dt) by the chain rule. Now, we can substitute the given values into the formula to find the rate of change of surface area:
r = 8 m (given)
dr/dt = -3 m/s (negative sign because the radius is decreasing)
π ≈ 3.14 (constant)
dA/dt = 8πr (dr/dt)
dA/dt = 8π(8)(-3)

bobby has 37 pineapples and johnny has 35 times more pineapples than bobby. how many more pineapples does johnny have than bobby?
Johnny has 1258 more pineapples than Bobby.
Bobby has 37 pineapples, Johnny has 35 times more pineapples than Bobby. To find how many more pineapples does Johnny have than Bobby, we can use the below formula,
More pineapples = Johnny's pineapples - Bobby's pineapples
Let x be the number of pineapples that Bobby has. Therefore, the number of pineapples owned by Johnny is 35x.
It is given that Bobby originally has 37 pineapples, thus x = 37. The number of pineapples Johnny has = 35*37 = 1295
Thus, difference in number of pineapples between Johnny and Bobby:
=1295-37 = 1258
Therefore, Johnny has 1258 more pineapples than Bobby.

USE A MODEL It takes one fuel line 3 hours to fill an oil tanker. How fast must a second fuel line be able to fill the oil tanker so that, when
used together, the two lines will fill the tanker in 45 minutes?
It must be able to fill the tanker in
hour(s).
The second fuel line must be able to fill the oil tanker at a rate of 2.67 tanks per hour in order to fill the tanker in 45 minutes when used together with the first fuel line.
Let's first find the rate of the first fuel line, which can fill the oil tanker in 3 hours. The rate is calculated as follows:Rate of the first fuel line = 1 tank / 3 hours = 1/3 tanks per hour
Let's assume that the rate of the second fuel line is x tanks per hour. When both fuel lines are used together, their combined rate is the sum of their individual rates:
Combined rate = Rate of the first fuel line + Rate of the second fuel line
We need to fill the tanker in 45 minutes, which is 0.75 hours. So, we can set up the equation:1 tank / 0.75 hours = (1/3) tank per hour + x tanks per hour
Simplifying the equation, we get:
1 tank / 0.75 hours - 1/3 tank per hour = x tanks per hour
x = (1 tank / 0.75 hours - 1/3 tank per hour)
x = 2.67 tanks per hour
Therefore, the second fuel line must be able to fill the oil tanker at a rate of 2.67 tanks per hour in order to fill the tanker in 45 minutes when used together with the first fuel line.

volume of a sphere = ³, where r is the radius. The radius of a spherical planet is 6052 km, and its mass is 4.87 × 1027g. Calculate the density of the planet in kilograms per cubic metre (kg/m³). Give your answer in standard form to 3 s.f.
Answer:
5240 kg/m³
Step-by-step explanation:
You want the average density of a planet with radius 6052 km and mass 4.87×10^27 g.
Unit conversionThe mass is given in grams, and the corresponding unit in the desired answer is kilograms. There are 1000 g in 1 kg, so 4.87×10^27 g = 4.87×10^24 kg.
The radius is given in km, and the corresponding unit in the desired answer is meters. There are 1000 meters in 1 km, so 6052 km = 6052×10^3 m. (We could adjust the decimal point, but we choose to let the calculator do that.)
DensityThe units of density tell you it is computed by dividing the mass by the volume:
ρ = mass/volume
The volume of the sphere is found using the given formula, so the density is ...
ρ = (4.87×10^24 kg)/(4/3π(6052×10^3 m)^3)
ρ ≈ 5240 kg/m³
The average density of the planet is about 5240 kg/m³.
__
Additional comment
This is comparable to the average density of Earth, which is about 5520 kg/m³.

Jason worked for 14/3 hours on Monday, and his friends Sheldon worked for 25/6 hours.How many more hours did Jason work than Sheldon?
Answer:
Step-by-step explanation:
To find out how many more hours Jason worked than Sheldon, we need to subtract the number of hours Sheldon worked from the number of hours Jason worked:
Jason's hours = 14/3
Sheldon's hours = 25/6
Jason's hours - Sheldon's hours = (14/3) - (25/6)
To subtract fractions, we need to have a common denominator, which in this case would be 6:
(14/3) - (25/6) = (28/6) - (25/6) = 3/6
Simplifying the result, we get:
3/6 = 1/2
Therefore, Jason worked 1/2 more hours than Sheldon.
Jason worked 1/3 more hours than Sheldon.
To find out how many more hours Jason worked than Sheldon, we need to subtract the number of hours Sheldon worked from the number of hours Jason worked.
Jason worked for 14/3 hours, which can be simplified to 4 and 2/3 hours. Sheldon worked for 25/6 hours, which can be simplified to 4 and 1/6 hours.
Subtracting the hours Sheldon worked from the hours Jason worked, we get: 4 and 2/3 - 4 and 1/6 = 2/3 - 1/6 = 1/3.
Therefore, Jason worked 1/3 more hours than Sheldon.

Let sin 60° =
√3
2
Find the measure of angle 3, in degrees, for cos
√√3
2
Answer/Step-by-step explanation:
We know that sin 60° = √3/2, and we can use this information to find cos 60°:
cos 60° = √(1 - sin^2 60°) = √(1 - 3/4) = √(1/4) = 1/2.
To find the measure of angle 3, we can use the formula:
cos(180° - 2x) = -cos(2x)
We want to solve for x when cos 2x = √(√3/2) = √3/2 * 1/√2 = √3/2√2
cos(180° - 2x) = -cos(2x)
cos(2x) = √3/2√2
180° - 2x = 150° or 210°
x = 15° or 35°
Therefore, the measure of angle 3 can be either 15° or 35°.
