Answer true
Explanation:becoz it's true
Answer:
O2, oxygen.
Explanation:
Hello.
In this case, for the undergoing chemical reaction, we need to compute the moles of CO2 yielded by 85 g of CH4 (molar mass = 16 g/mol) and by 320 g of O2 (molar mass 32 g/mol) via the following mole-mass relationships:

Considering the 1:2:1 among CH4, O2 and CO2. Therefore, since 320 g of O2 yield the smallest amount of CO2 we infer that the limiting reactant is O2.
Best regards.
Exothermic and Endothermic Reactions. The release of energy in chemical reactions occurs when the reactants have higher chemical energy than the products. ... Conversely, if the enthalpy increases during a reaction, a corresponding amount of energy must be absorbed from the surroundings.
