Significant figures for 7.06 × 10^5 ÷ 5.3 × 10^-2

Explanation:

In multiplication  and division problems, your answer can have no more significant figures than the number with the fewest significant figures.

(by my calculator)  

There are three significant figures in 7.06 and two in 2.3.

You must round to significant figures and report the answer as 1.3 × 1.0⁷.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

its first and third is your answer i did the qustion the fourth isnt right
