Answer:
Carbon dioxide and water.
Explanation:
Oxidation which is combustion with oxygen gives off CO2 and H20 under complete combustion.
Answer: Option (B) is the correct answer.
Explanation:
Equilibrium constant is defined as the relationship present between the amounts of products and reactants which are there at equilibrium in a reversible chemical reaction at a given temperature.
For example,
Mathematically,
As the value of equilibrium constant depends on rate constants of the forward and reverse reactions. And, this rate of reaction also changes with change in pressure and temperature.
Therefore, it will also lead to change in equilibrium constant but it does not depend on initial amount pf reactants.
Thus, we can conclude that in general, the value of the equilibrium constant for a chemical reaction does NOT depend on the initial amounts of reactants present.
Answer:
The answer to your question is 1.2 moles of copper
Explanation:
Data
mass of copper = 75 g
moles = ?
Process
1.- Look in the periodic table for the atomic mass of copper.
Atomic mass = 63.55 g/mol
2.- Use proportions to determine the moles of copper in 75 g
63.55 g of copper -------------------- 1 mol
75 g of copper -------------------- x
Use cross multiplication
x = (75 x 1) / 63.55
x = 75 / 63.55
x = 1.18 moles ≈ 1.2 moles of copper
I believe that the answer to the question provided above is that molecules in solid are compact and are connected. It requires huge energy to move it, thus requires high temperature.
