Type the correct answer in each box.
solve the problems. express your answers to the correct number of significant figures.
0.09 + 1.324 =
41.0 + 78.3 =

Explanation:

The significant figures are the digits of a number that we consider not null. All nonzero digits are significant. The zeros between two numbers (other than zero) are significant. The zeros to the left of the first significant figure are not.

In an operation the result must be expressed with the greatest number of significant figures that have their terms

oh it is true if thats what you are asking

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
