K + Zn --> K + Zn These two metals do not form a compound. There is no reaction.
The reaction is:
2KOH(aq) + ZnCl2(aq) --> 2KCl(aq) + Zn(OH)2(s)
The products are potassium chloride and a zinc hydroxide precipitate.
K2S(aq) + Zn(CH3CO2)2(aq) --> 2KCH3CO2(aq) + ZnS(s)
4K (s) + O2 (g) -----> 2K2O
Please mention this reaction !
yes
KCl is the chemical formula unit of potassium chloride not a chemical equation.
from a balanced chemical equation
we should balance a chemical equation so that both the sides of the elements and compounds are equal.
You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).
Combustion reaction equations balance the same way that any other chemical equation does. Every atom that appears on the left side of the equation must also appear on the right side of the equation. No atoms are created or destroyed in the process of a chemical reaction.
KCl is the chemical formula unit of potassium chloride not a chemical equation.
The balanced equation is: KHCO3 + HCl -> KCl + CO2 + H2O The products of the reaction are potassium chloride, carbon dioxide and water.
from a balanced chemical equation
2 KOH + H2CO3 = 2 H2O + K2CO3
balance your chemical reaction equation then calculate moles, then calculate weight.

if it is a redox reaction sometimes you can add water to help balance the equation
KI + NaCl = KCl + NaI
After a chemical reaction the reactants are transformed in other compounds - the products.
A chemical equation written in symbols is sometimes called a balance equation, because the numbers of each kind of atom have to balance on both sides. If it's written in words it's called a word equation.
