CH4 + 2 02 CO2 + 2 H2O AHx = -802.3 kJ Is the reaction exothermic or endothermic
If 1825 kJ of heat is released, how many grams of water will be produced?
If 58.5 g of CH4 reacts how much heat is released?

What is a metal replacement reaction

What mass of natural gas (ch4) must you burn to emit 276 kj of heat?

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
