How many significant figures are in this
measurement?
10.006 L

There are 5 significant figures in 10.006L

Explanation: Since there is a decimal point, all the digits after the decimal point also count as significant figures. Below is a key to help yu out:

Not Significant:

- Leading zeroes(in decimal): example- 0.0023= 2 sig figs

- Trailing zeroes with no decimal point: example- 2300= 2 sig figs

Significant:

- middle zeroes: example- 4003= 4 sig figs

-trailing zeroes with decimal point: example- 23.00= 4 sig figs

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
