The answer would be Ca + FeN = Ca3N2 + 2Fe
C. Ca and Br because they're metals and nonmetals
Answer: A mutation because a change in DNA that is natural is a mutation. :)
S + O₂ = SO₂
1 mole S ------------ 1 mole SO₂
? mole S ----------- 15.0 mole SO₂
S = 15.0 * 1 / 1
= 15 moles of S
hope this helps!
Decreasing the speed at which particles move.
That is the answer because less speed involves less energy to move each particle which translates to less energy being exerted on the container when the particle and the container collide. That would result in less pressure.
