Given the following unbalanced thermochemical equation, how much heat will be released from the combustion of 45.5 grams of ch4 in an excess of oxygen gas? ch4(g) + 2o2(g) → co2(g) + 2h2o(l) + 890 kj

2530kJ

Explanation:

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.
