Bonds are made of energy. There are certain energy changes that occur during the making or breaking of bonds and this is called enthalpy changes. When a bod is broke, energy is required to break...Read More
The correct answer to this question is A, T2=∆T1. Temperature changes are one of many ways an indication of a chemical change is occurring. Other signs include a change in color, an odor, and...Read More
The answer to this question is A. This is a type of limiting reactant problem wherein the acid is in deficiency. Half of the dihydrogen will evolve depending on the amount that will be placed. To...Read More
It is not true to say the one mole of hydrogen gas contains 6.02x 10^23 atoms of hydrogen. However, some true statements that involve hydrogen would be that one molecule of methane contains four...Read More
For those uninitiated to chemistry (like me), enthalpy is just the amount of heat that is given off in a specific chemical reaction. If a typical carbon-hydrogen bond gives off 412 kilojoules per...Read More
Correct answer option C - the amount of reactants and product do not change is always true for a chemical reaction that has reached equilibrium.
Chemical reaction at equilibrium occurs when...Read More
