Heyo,
Sugar is a pure substance. A pure substance is a substance that has chemical properties. Sugar is a pure substance.
Answer:
Sulphuric acid + Magnesium Carbonate → Magnesium sulphate + carbon dioxide + water
Explanation:
Sulphuric acid + Magnesium Carbonate
The products are;
Magnesium sulphate, carbon dioxide and water
MgCO3 (s) + H2SO4 (aq) → MgSO4 (aq) + CO2 (g) + H2O (l)
Word Equation;
Sulphuric acid + Magnesium Carbonate → Magnesium sulphate + carbon dioxide + water
Nitrogen gas consists of a diatomic nitrogen atom. So, the correct answer is B.
Im pretty sure it nitric acid
The statement is true in this situation is C. The size of Ffric is the same as the size of Fapp:
From the diagram, since the body is in equilibrium, the sum of vertical forces equals zero. Also, the sum of horizontal forces equal zero.
So, ∑Fx = 0 and ∑Fy = 0
Since Fapp acts in the negative x - direction and Ffric acts in the positive x - direction,
∑Fx = -Fapp + Ffric = 0
-Fapp + Ffric = 0
Fapp = Ffric
Also, since Fgrav acts in the negative y - direction and Fnorm acts in the positive y - direction,
∑Fy = Fnorm + (-Fgrav) = 0
Fnorm - Fgrav = 0
Fnorm = Fgrav
So, we see that the size of Fapp <u>equals</u> size of Ffric and the size of Fnorm <u>equals</u> the size of Fgrav.
So, the correct option is C
The statement which is true in this situation is C. The size of Ffric is the same as the size of Fapp.
