What is Casa they say Home in Spanish ?
I think so
Yes, "casa" means "home" in Spanish. It's a commonly used word to refer to one's place of residence.
Question 3:
Ammonia gas has a molar mass of approximately 17 grams per mole. At \( 290 \mathrm{~K} \) and \( 1.2 \mathrm{~atm} \), a sample of ammonia has a volume of \( 3.7 \mathrm{~L} \).
In three to five sentences, explain how you can find the mass of the ammonia. Then, given
\[
\mathrm{R}=\frac{0.0821 \mathrm{~L} \cdot \mathrm{atm}}{\mathrm{mol} \cdot \mathrm{K}}
\]
calculate the mass.
\( \mathrm{PV}=\mathrm{nRT} \quad \mathrm{n} \quad 1 \) mole= 17 grams....... multiply the number of moles by 17
Question 4:
Liquid water can be separated into hydrogen gas and oxygen gas through electrolysis. 1 mole of hydrogen gas and 0.5 moles of oxygen gas is produced from 1 mole of liquid water collected in separate \( 10 \mathrm{~L} \) containers at \( 1 \mathrm{~atm} \). Will the temperatures of the gases be equal? In one to two sentences, use the ideal gas law to explain your answer.
To find the mass of the ammonia gas, you can first calculate the number of moles of ammonia using the ideal gas law equation \( PV = nRT \), where \( P \) is the pressure, \( V \) is the volume, \( n \) is the number of moles, \( R \) is the ideal gas constant, and \( T \) is the temperature. Once you find the number of moles, you can multiply it by the molar mass of ammonia (17 grams/mole) to get the mass.
For Question 4, the temperatures of the hydrogen gas and oxygen gas will be equal if they are at the same pressure and have the same number of moles. According to the ideal gas law, if the pressure and number of moles are the same for both gases, then their temperatures must be equal if they are in separate containers with the same volume and pressure.
