Notice that in the equation given, there is 1 mol of Mg3N2
and 6 mol of H2O. Consequently, the question is requesting, if we took 2.5 mol
of Mg3N2, how many mol of H2O would be essential to complete a similar reaction
-- in quintessence, multiplying everything by 2.5:
the solution would be: 6 * 2.5 = 15 mol
Answer:
Widening of blood vessels.
Explanation:
The reduction of aldehydes, ketones, organic acids causes the formation of alcohols that is used for different process in the human body. This alcohol increase the width of the blood vessels as it enters the bloodstream causing greater flow of blood to the skin surface as well as temporary feeling of warmth. It also increased heat loss and rapid body temperature decrease that produces cooling effect in the body.
Answer: 24 gram is a final Answer.
Explanation:1 mol of carbon weight is 12 gram then
12.044×1023 contain 2 mole carbon so
Answer:
14 J of heat
Explanation:
Recall that the enthalpy of reaction is defined as the enthalpy change that occurs in a system when matter is transformed by a given chemical reaction, if all reactants and products are in their standard states. Here we have the heat of formation of six moles of the substance and we are expected to use it to obtain the the heat of formation of one mole of the compound and we can do that by simple proportion as shown below;
If 6 moles of the compound produces 84J of heat
1 mole of the substance will produce 1×84/6 = 14 J of heat
Answer:
Solid, liquid, gas
Explanation:
add thermal energy to solid and it becomes liquid, add thermal energy to liquid it becomes gas
