in two or more complete sentences explain how to balance the chemical equation,
ca + n2 ⟶ ca3 + n2 and include all steps.

answer:

to balance ca + n2 = ca3n2 you'll need to be sure to count all of atoms on each side of the chemical equation. once you know how many of each type of atom you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation for calcium + nitrogen gas.

explanation:

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

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
