What is the volume of 2 mol of chlorine gas at STP?
vladimir1956 [14]
The conversion factor for volume at STP is \frac {1mol}{22.4L} or \frac {22.4L}{1mol}. Since we want volume, we would use \frac {22.4L}{1mol}. We conclude with the following calculations:

2molCl_{2}*\frac {22.4LCl_{2}}{1molCl_{2}} = 44.8L Cl_{2}

The answer is 44.8L Cl2

Which reaction is endothermic? HCl + NaOH Right arrow. NaCl + H2O + 58 kJ 6CO2 + 12H2O + energy Right arrow. C6H12O6 + 6O2 + 6H2
satela [25.4K]

Answer:

6CO_2 + 12H_2O + Energy->C_6H_{12}O_6 + 6O_2 + 6H_2O

Explanation:

-An endothermic reaction is a chemical reaction that gains or absorbs heat from its surrounding in the form of heat.

-During the reaction, the temperature of the surrounding reduces.

-From the reactions given:

6CO_2 + 12H_2O + Energy-> C_6H_{12}O_6 + 6O_2 + 6H_2O

is the only endothermic reaction.

6CO_2 + 12H_2O + Energy->C_6H_{12}O_6 + 6O_2 + 6H_2O
