<u>Answer:</u> The correct answer is Option C.
<u>Explanation:</u>
Net ionic equation of any reaction does not include any spectator ions.
Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.
The chemical equation for the reaction of sodium bicarbonate and acetic acid is given as:
Ionic form of the above equation follows:
As, sodium and acetate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.
The net ionic equation for the above reaction follows:
Hence, the correct answer is Option C.
- Mass (m) = 1 Kg
- Acceleration due to gravity (g) = 9.8 m/s^2
- We know, weight = mass × acceleration due to gravity.
- Therefore, weight of the object

Answer:
The answer to your question is:
a) 36 g of water
Explanation:
MW SO₂ = 32 + 32 = 64 g
MW Br = 80 g
MW H₂O = 18 g
MW HBr = 81 g
MW H₂SO₄ = 98
Balanced reaction:
SO₂ + 2Br + 2H₂O ⇒ 2HBr + H₂SO₄
64g 2(80) 2(18) 2(81) 98
64.1 159.9 161.9 98.1
Rule of three with Br and H2O
160 g ---------------- 36 g
160 ------------------- x
x = 160(36)/160 = 36 g oh water
The magma in the mantle layer moves, and while it's moving the plates move as well, forming mountains, volcanoes, ridges, etc.
