Answer:
The reaction between zinc and acetic acid is a single-replacement reaction. During this type of reaction basically one element replaces one compound.
The balanced equation for the reaction between zinc and acetic acid is
Zn(OH)_2 +2CH_3 COOH ----> Zn(CH_3COO)_2+2H 2O
Or this might help too!
Balanced Chemical Equation
A balanced chemical equation is defined as the chemical equation which has an equal number of atoms on both sides of the reaction arrow. A balanced chemical equation is based on the law of conservation of mass.

This reaction is an example of a reaction between an acid and a metal. When an acid reacts with a metal, salt, and Hydrogen gas forms. The Hydrogen gas formed here can be tested as it burns with a POP sound.

Answer:
a) 
2 moles of Zinc sulphide in solid form reacts with 3 moles of Oxygen in gaseous form to give 2 moles of Zinc oxide in solid form and 2 moles of sulphur dioxide in gaseous form.
b) 
1 mole of calcium hydride in solid form reacts with 2 moles of liquid water to give 1 mole of calcium hydroxide dissolved in water and 2 moles of hydrogen in gaseous form.
The chemical reactions are written by writing the chemical formula of the reactants on left side of the arrow followed by chemical formula of the products. The number of atoms of each element must be balanced to follow the law of conservation of mass.
The unbalanced chemical equation with the corresponding phase for each substance is shown below:
Cu₍s₎ + H₂SO₄₍aq₎ → CuSO₄₍aq₎ + SO₂₍g₎ + H₂O₍l₎
The copper metal is solid, the sulfuric acid and copper sulfate are in aqueous solution. Water is in the liquid phase while sulfur dioxide is in the gas phase.
In order to obtain the balanced equation, we must ensure that the number of atoms present in the reactant side is equal to that in the product side. First, we list the elements involved and count their number on each side.
Reactant Product
1 Cu 1
2 H 2
1 S 2
4 O 5
To balance the equation, we need to have 2 moles of H₂SO₄ and 2 moles of H₂O. The balanced chemical equation is then:
Cu₍s₎ + 2H₂SO₄₍aq₎ → CuSO₄₍aq₎ + SO₂₍g₎ + 2H₂O₍l₎
Reactant Product
1 Cu 1
4 H 4
2 S 2
8 O 8
Answer:
1. A
2. B
Explanation:
1. Most of the answers don't make that much sense, so using process of elimination I resulted in this answer. I recommend you also try to check with others.
2. This question also was pretty confusing but when using process of elimination I resulted in either A or B. To me B makes more sense.
I think that pressure will affect the solubility of gasses the most. The reason why I think this is that gasses are affected the most by pressure change. By definition solids and liquids are not easily affected by pressure by how close the molecules are to each other in both of those phases.
I hope this helps. Please let me know if you have any further questions or need any clarification.
