What is a compound?Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.
Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.
They have a unique chemical structure held together by chemical bonds Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.

What is the molarity of a solution composed
of 4.27 g of potassium iodide (KI) dissolved in
enough water to make 0.304 L of solution?
Answer in units of M.
Answers
Answer:
0.0845 M
Explanation:
First we convert 4.27 grams of potassium iodide into moles, using its molar mass:
Molar Mass of KI = 166 g/mol4.27 g ÷ 166 g/mol = 0.0257 molNow we calculate the molarity of the solution, using the number of moles and the given volume:
Molarity = moles / litersMolarity = 0.0257 mol / 0.304 L = 0.0845 MIn "The Philosophy of the Manufacturers" by Andrew Ure, the author compares a factory worker to a handmade

b. The lot of mankind, have been too little dwelt upon; while, on the other har, it has been accused of

Answers
"Certainly no muscular fatigue to sustain, while it procures for him good, unfailing wages, besides a healthy workshop gratis."
What idea does the quote supports?The concept that factory workers have it better than handcrafted workers is supported by this textual quotation since it implies that factory work is less physically taxing and offers better pay and working conditions.The author is suggesting that factory worker is in better position than hand worker.This is beneficial for the worker, as it means they can work for longer periods of time without experiencing the same level of exhaustion.Finally, the quote states that a factory provides a "healthy workshop gratis" which means that the factory provides a healthy and clean working environment for the worker without any additional costs. This is beneficial for the worker, as it means they can work in a safe and healthy environment, which is not always the case for hand workers.To know more about healthy workshop conditions quote, check out :

Le Châtelier’s principle is applied in the bottling of carbonated soft drinks. You are probably familiar with the “hissing” or “popping” sound of opening of either an aluminum soda can or plastic bottle. This occurs by adding carbon dioxide to water to produce carbonic acid in a reversible reaction, which is shown below: H2O(l) + CO2(g) <-------------------> H2CO3(aq) As you may have known, these beverages are bottled under increased pressure, placing stress on the equilibrium. Following Le Châtelier’s principle, the system shifts to the right to reduce the stress, in response to the increase in pressure. When the bottle or can is opened, the pressure is reduced. This reaction favors the reactants, thus shifting the system to the left, and CO2 gas forms and comes out of the solution. Question # 8 :You open a can of Coca-Cola and you pour it into a glass with ice. You notice that the soda is very fizzy and quite effervescent. What do you think is responsible for this? Group of answer choices A. H2O formation under pressure. D. Release of H2O as a result of opening the can. B. H2CO3 formation under pressure. C. Release of CO2 as a result of opening the can.
Answers
Answer:
C. Release CO2 due to can opening
Explanation:
Le Châtelier’s principle states that when a reaction is at equillibrium and it is disturbed it will respond to return to equilibrium.
SO
H2O(l) + CO2(g) <-------------------> H2CO3(aq)
When you open a bottle of coke it is under pressure and not at equillibrium so it reacts by releasing the gas to reach equilibrium it can be seen in the equation above just that this is for club soda not coke, the idea applies though
If hydrogen diffuses at the rate of 10 cm³ per second from a given apparatus under given conditions of temperature and pressure, calculate under same conditions: a) the volume of oxygen (O₂) which diffuses in 20 seconds

The ionization energies of Calcium are (in KJ/mol): 1st: 589.8 2nd: 1145.4 3rd: 4912.4
Explain why there is such a large jump from 2nd to 3rd ionization energy.
pleaseeee i need help, my brain is just not getting it
Answers
Answer:
See whole explanation to understand
Explanation:
the reason why there is such a large jump from 2nd to 3rd ionization energy for calcium is because to remove the third electron, a larger amount of energy is required, since the shell is closer to the nucleus, and higher attraction exists between them. This is why the second ionization energy is 1125.4 and then the third IE is 4912.4 which is a very big difference. It's all about the elections and energy!!
Atoms of different element can not have same atomic number because only same type of atoms combine to form element. Atoms belonging to different element can have different atomic number. Therefore, higher attraction between shell and nucleus, there is such a large jump from 2nd to 3rd ionization energy.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same. Two or more than two atoms with different physical or chemical properties can not combine together to form an element.
The reason why there is such a large jump from 2nd to 3rd ionization energy for calcium is because to remove the third electron, a larger amount of energy is needed, since the shell is closer to the nucleus, and higher attraction exists between them.

Answers
A chemist morning commute is 40.2 kilometers. Given an average speed pf 60.5 mph, 0.66 minutes will it take him to arrive at work.
What is average speed ?The overall distance the object covers in a given amount of time is its average speed. A scalar value represents the average speed. It has no direction and is indicated by the magnitude.
If you know how far something has travelled and how long it took to get there, you can calculate its average speed. Speed is calculated as follows: speed = distance * time.
Distance = speed × time
40.2 = 60.5 × time
time = 40.2 / 60.5
= 0.66 minutes

At 25.0° C, a 10.00 L vessel is filled with 5.25 moles of Gas A and 7.75 moles of Gas B. What is the total pressure in atm?
Answers
Answer:
23.12 atm
Explanation:
First, add together the moles of the two samples:
5.25 moles + 4.20 moles = 9.45 moles
273 + 25 = 298 K for the temperature
volume is 10.0 L
Since we have moles now, we have to rearrange our ideal law equation to solve for pressure:
[tex]P = \frac{nRT}{V}[/tex]
[tex]\frac{(9.45 moles) X (0.08206) X (298 K)}{10.0 L}[/tex]
9.45 X .08206 X 298 all divided by 10.0 = 23.09202 atm (or 23.12)

Q)A certain mass of gas occupies a volume 2.5 L at 90atm. What pressure would the gas exert if it were placed in a 10 L container at the same temperatur?
Answers
Answer:
23 atm
Explanation:
Step 1: Given data
Initial volume (V₁): 2.5 LInitial pressure (P₁): 90 atmFinal volume (V₂): 10 LFinal pressure (P₂): ?Step 2: Calculate the final pressure of the gas
If we assume constant temperature and ideal behavior, we can calculate the final pressure of the gas using Boyle's law.
P₁ × V₁ = P₂ × V₂
P₂ = P₁ × V₁ / V₂
P₂ = 90 atm × 2.5 L / 10 L = 23 atm
As expected, since the volume increased, the pressure decreased.

Final volume, V₂ = 16 ft³
We need to find the new temperature. The relation between temperature and volume is given by :

Explanation:
Hello there!
In this case, according to the given chemical reaction at equilibrium, we can set up the equilibrium expression as follows:
[tex]K=\frac{[CO][Cl_2]}{[COCl_2]}[/tex]
Which can be written in terms of x, according to the ICE table:
[tex]0.32=\frac{x^2}{0.015M-x}[/tex]
Thus, we solve for x to obtain that it has a value of 0.01436 M and therefore, the concentrations at equilibrium turn out to be:
[tex][CO]=[Cl_2]=0.01436M[/tex]
[tex][COCl_2]=0.015M-0.01436M=0.00064M[/tex]
