4 atoms
Explanation:
On the product side, we expect to find 4 atoms of the product.
An atom is the smallest indivisible particle that takes part in a chemical reaction.
An element is a distinct substance that cannot be split-up into simpler substances. Such substances consist of only one kind of atom.
In this reaction we have:
2 elements: Mg O
on the reactant side:
We have two moles of Mg: 2 atoms of Mg
1 mole of oxygen gas: 2 atoms of O
total atoms: 4 atoms
According to the law of conservation of matter "in a chemical reaction, matter is neither created nor destroyed".
We expect to find 4 atoms of products which is MgO on the product side.
2Mg + O₂ → 2MgO + heat

Explanation:
The rectangular components of a vector 
having a magnitude v and angle θ are:
The golf ball has an initial speed of 75 m/s at an angle of 60 degrees.
The variables of the equations have the values:
v = 75 m/s
θ = 60°
Substituting into the formula:
Without specifying units and with precision to the hundredths place:
If he dropped them both at the same time, then as close as anyone could tell, they both hit the ground at the same time.
