The vapor of a nitrogen oxide with a mass of 1.08 g occupies 22.4 L at 0oC and pressure 7.60 Torr. What is the proper chemical name of this nitrogen oxide
The proper chemical name of the nitrogen oxide compound having a mass of 1.08 g is dinitrogen pentoxide, N₂O₅
How to determine the mole of the nitrogen oxideVolume (V) = 22.4 L Pressure (P) = 7.6 torr Temperature (T) = 0 °C = 0 + 273 = 273 KKGas constant (R) = 62.364 torr.L/Kmol Number of mole (n) =?Using the ideal gas equation, the number of mole of the nitrogen oxide can be obtained as follow:
PV = nRT
Divide both side by RT
n = PV / RT
n = (7.6 × 22.4) / (62.364 × 273)
n = 0.01 mole
How to determine the molar mass of the compound Mass = 1.08 gMole = 0.01 mole Molar mass =?Molar mass = mass / mole
Molar mass = 1.08 / 0.01
Molar mass = 108 g/mol
Comparing the molar mass of the compound with the molar mass of nitrogen oxide compounds, only dinitrogen pentoxide (N₂O₅) has a molar mass of 108 g/mol.
Thus, the name of the compound is dinitrogen pentoxide
CheckMolar mass of N₂O₅ = (14×2) + (16×5)
Molar mass of N₂O₅ = 28 + 80
Molar mass of N₂O₅ = 108 g/mol

What is the hydroxide ion concentration of a solution with a hydrogen ion concentration of 7.58 × 10-10 M?
At what temperature would 2. 10 moles of N2 gas have a pressure of 2. 25 ATM and in 25. 0 L tank?
Answer:
About 326 K.
Explanation:
Recall the ideal gas law:
[tex]\displaystyle PV = nRT[/tex]
Where P is the pressure, V is the volume, n is the number of moles, R is the universal gas constant, and T is the temperature.
Because we want to solve for temperature T:
[tex]\displaystyle T = \frac{PV}{nR}[/tex]
Substitute and evaluate. R has a value of 0.08206 L-atm/mol-K:
[tex]\displaystyle \begin{aligned} T & = \frac{(2.25\text{ atm})(25.0\text{ L})}{(2.10\text{ mol})\left(\dfrac{0.08206\text{ L - atm}}{\text{mol - K}}\right)} \\ \\ & = 326\text{ K}\end{aligned}[/tex]
In conclusion, the temperature of the gas will be about 326 K.

Learning Task 1: In your notebook, write the appropriate tempo for the following actions. Then, demonstrate the action in front of your parents/guardians. 1. a man walking 4. a jet flying 2. a rabbit hopping 5. a horse running 3. a turtle crawling
A tempo is a speed or rhythm, at which the action is performed or the activity is done. A man walking is a moderate tempo and a turtle is a slow tempo.
What are the types of tempo?Tempo is the speed or rate at which an action or activity is conducted. It can be moderate, fast, or slow in action.
A slow tempo is a speed that is slow in general speed and is not immediate in action like turtle crawling is a slow tempo as it crawls very slowly.
A moderate tempo is the action that is intermediate between slow and the fast tempo and is a regular movement like a man walking.
A fast tempo is a fast action or activity performed by someone quick and effective like a rabbit hopping, a horse running, and a jet flying.
Therefore, the tempo can be slow, moderate, or fast.

Based on the two starting amounts of Cu and HNO₃, the amount of NO₂ produced should be 0.0944 moles.
Calculate the concentration (in molarity) of the gas if that gas were confined to the 250 mL of space in the flask.
The concentration (in molarity) of the gas if that gas were sealed to the 250 mL of space in the flask is 0.3776 M.
How do we calculate the molarity?Molarity of any substance is defined as the number of moles of solute present in per liter of the solution and it will be represented as:
M = n/V, where
n = moles = 0.0944mol
V = volume = 250mL = 0.25L
On putting values, we get
M = 0.0944 / 0.25 = 0.3776 M
Hence required molarity is 0.3776 M.

Answer:
B) It is not balanced for oxidation state or for number of atoms
Explanation:
I got this question correct on my Edge quiz, so I know that this is the right answer.
The reactant side has 2 oxygen atoms, while the product side only has 1. This means the mass isn't balenced. In addition, the oxidation (charge) on the reactant side is 0, while it's -2 on the product side. This means the oxidation nor mass is balenced.

Which property of water contributes most to the ability of fish in lakes to survive very cold winters?.
Answer:
And that means fish must be able to survive down here. This is due to a special property of water: the elasticity of H2O. We know that when the temperature sinks below freezing, water first contracts and then expands as it begins to turn to ice. Ice, being lighter than water, floats.
Explanation:
The property of water that allows fish to survive in a lake that is frozen over is the fact that ice is less dense than liquid water.
