Answer:
What is a formation reaction? it is when a mol of a product it is formed from its elements constituents
What is standard heat of formation? the standard heat of formation or formation enthalpy, it is the amount of energy necessary for produce a mol of the product when its elements constituent react.
What is a combustion reaction? It is when a hydrocarbon reacts with oxygen and produce water a carbon dioxide
What is standard heat of combustion? It is the amount of energy released during a combustion reaction, measuring per mass or volume unit
Explanation:
A example of formation reaction is:
2H2 + O2 =2H2O
I hope my answer can help you
Answer is: 79.8 grams of copper(II) sulfate.
N(CuSO₄) = 3.01·10²³; number of molecules.
n(CuSO₄) = N(CuSO₄) ÷ Na.
n(CuSO₄) = 3.01·10²³ ÷ 6.02·10²³ 1/mol.
n(CuSO₄) = 0.5 mol; amount of substance.
m(CuSO₄) = n(CuSO₄) · M(CuSO₄).
m(CuSO₄) = 0.5 mol · 159.6 g/mol.
m(CuSO₄) = 79.8 g; mass of substance.
M - molar mass.
I think the particle starts to move slowly around because no heat or pressure is applied to it
When an electrolyte dissolves in water, the resulting solution conducts an electric current.
