1. tell the number of atoms of each element in these compounds. (1pt per blank) n2o3 of nitrogen atoms of oxygen caco3 of calcium of carbon of oxygen

- has 2 atoms of nitrogen and 3 atoms of oxygen. has 1 atom of calcium, 1 atom of carbon and 3 atoms of oxygen.

Explanations:- The numbers written as subscripts for the elements in formulas of the compounds represents the number of atoms of that particular element.

The first compound is and in this the subscript of N is 2 and that of O is 3. It means it has 2 atoms of N and 3 atoms of O.

Second compound is and in this the subscript of Ca is not shown it means it is 1, similarly the subscript of C is 1 and subscript of O is 3. So, the compound has 1 atom of Ca, 1 atom of C and 3 atoms of O.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

c, liquids evaporate, creating a gas
