According to Law of conservation of mass - The mass of matter can neither be created nor be destroyed.
So, th no. of mass in reactants and products in chemical eequation should be same.
To satisfy this Law chemical equation should be balance.
chemical equations should be balanced as an equation should have its rhs and lhs equal.
A chemical equation needs to be balanced to reflect the law of conservation of matter/mass. The same numbers and kinds of atoms in the reactants must also be present in the products.
balance chemical equation, change only the coefficients of the formulas.
False. Subscript cannot be change to balance chemical equations. Only coefficients can be added to balance chemical equation.
false
PbCl2 is the molecular formula (not chemical equation) of lead(II) chloride.
A coefficient is written in front of a formula to balance a chemical equation.
we should balance a chemical equation so that both the sides of the elements and compounds are equal.
Jean Beguin was the first iatrochemist to balance a chemical equation.
balance chemical equation, change only the coefficients of the formulas.
False. Subscript cannot be change to balance chemical equations. Only coefficients can be added to balance chemical equation.
false
KCl is the chemical formula unit of potassium chloride not a chemical equation.
Evaporation is not a chemical change and so there is no chemical equation.
from a balanced chemical equation
balance your chemical reaction equation then calculate moles, then calculate weight.
PbCl2 is the molecular formula (not chemical equation) of lead(II) chloride.
balance the equation. calculate moles of product.
A coefficient is written in front of a formula to balance a chemical equation.
