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.

Missing question: what is the density of 53.4 wt% aqueous NaOH if 16.7 mL of the solution diluted to 2.00L gives 0.169 M NaOH?
Answer is: density is 1.52 g/mL.
c₁(NaOH) = ?; molarity of concentrated sodium hydroxide.
V₁(NaOH) = 16.7 mL; volume of concentrated sodium hydroxide.
c₂(NaOH) = 0.169 M; molarity of diluted sodium hydroxide.
V₂(NaOH) = 2.00 L · 1000 mL/L = 2000 mL; volume of diluted sodium hydroxide.
Use equation: c₁V₁ = c₂V₂.
c₁ = c₂V₂ / V₁.
c₁ = 0.169 M · 2000 mL / 16.7 mL.
c₁(NaOH) = 20.23 M.
m(NaOH) = 20.23 mol · 40 g/ml.
m(NaOH) = 809.53 g.
The mass fraction is the ratio of one substance (in this example sodium hydroxide) with mass to the mass of the total mixture (solution).
Make proportion: m(NaOH) : m(solution) = 53.4 g : 100 g.
m(solution) = 1516 g in one liter of solution.
d(solution) = 1516 g/L = 1.52 g/mL.
Answer:
(dont know if this is correct took this last year)
Explanation:
1 hydrogen atom plus 1 chlorine atom is equal to 2 hydrochloric acids due to the fact that there are 2 atoms in both substances and the equation has to stay constant throughout according to the law of conservation of mass
same goes for 2 sulfate atoms and 3 oxygen atoms
in order to balance this this the sulfate atoms have to take into account that their are 2 sulfate atoms and 6 oxygen atoms so you have to add more sulfates to make them both equal 6 then balance it with the oxygens
