Interpretation:
It should be determined that, how many grams of acetylene and how many litres of
Concept Introduction:
STP: A system is said to have a temperature of zero degree centigrade
Enthalpy change: The heat change when molar quantities of reactants as specific by the chemical equation react to form products at standard conditions.
Enthalpy depends in the physical state of reactants and the products and the conditions under which the reaction occurs.
Standard enthalpy formation: The standard enthalpy of formation

- 6. If 1.85 L of diphosphorous pentoxide form at a temperature of 50.0 °C and 1.12 atm, what is the mass (in g) of phosphorus that reacts?arrow_forwardThe airbags that protect people in car crashes are inflated by the extremely rapid decomposition of sodium azide, which produces large volumes of nitrogen gas. 1. Write a balanced chemical equation, including physical state symbols, for the decomposition of solid sodium azide (NaN3) into solid sodium and gaseous dinitrogen. 1 2. Suppose 64.0 L of dinitrogen gas are produced by this reaction, at a temperature of 16.0 °C and pressure of exactly 1 atm. Calculate the mass of sodium azide that must have reacted. Be sure your answer has the correct number of significant digits. 08 0-0 00arrow_forwardSuppose 295 g of NO3 flows into a swamp each day.
