The given question is incomplete, the complete question is:
A reaction between liquid reactants takes place at 10.0 °c in a sealed, evacuated vessel with a measured volume of 35.0 L. Measurements show that the reaction produced 28. g of dinitrogen difluoride gas. Calculate the pressure of dinitrogen difluoride gas in the reaction vessel after the reaction. You may ignore the volume of the liquid reactants. Round your answer to 2 significant digits. pressure:atm
Answer:
The correct answer is 0.28 atm.
Explanation:
The temperature mentioned in the given reaction is 10 degree C, which after conversion becomes 283 Kelvin (273+10 = 283K).
The volume mentioned in the reaction is 35 Liters.
The reaction produced 28 grams of dinitrogen difluoride gas (N2F2). The n or the no of moles of the gas can be determined with the help of the formula:
moles of N2F2 = mass/molar mass
= 28/66 (molar mass of N2F2 is 66 g/mol)
= 0.424
The pressure of the gas can be determined by using the equation of the ideal gas law, that is, PV = nRT
P * 35 = 0.424 * 0.0821 * 283
P = 0.28 atm
It wont melt like gold and copper would at that temperature
CaCl2 + H2O are produced when HCl react with Ca(OH)2
Explanation
equation for reaction is as follows
Ca(OH)2 + 2HCl → CaCl2 +2H2O
1 mole of calcium hydroxide (Ca(OH)2 reacted with 2 moles of hydrochroric acid (HCl) to form 1 moles of calcium chloride CaCl2 and water H2O. This type of reaction is known as neutralization reaction since it between an acid (HCl) and a base (Ca(OH)2
