Answer:

to find the new rate when the concentration of reactants changes

Explanation:

The rate of a chemical reaction is the rate of change of concentration of reactants or products with time. As a reaction progresses the concentration of reactant decreases and the concentration of product increases. The rate law is the product of the rate constant and the molar concentration of the reactant(s) involved in the chemical reaction. Due to direct proportionality between rate law and concentration of reactants, the rate law is directly affected by the change in the concentration of the reactants.

How many moles in one gram of Calcium ??

kirill [66]

Answer:

0.0249 moles in 1 g of Ca

Explanation:

Let's think in the molar mass of Ca.

Ca = 40.08 g/mol

So 1 mol weighs 40.08 grams, or in the opposite 40.08 grams is the weigh of 1 mol

The rule of three will be:

40.08 g are contained in 1 mol
