Answer: 2:3
Explanation: Decomposition reaction is a type of chemical reaction in which one reactant gives two or more than two products.
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
according to the balanced chemical equation, 2 moles of potassium chlortae on decomposition gives 2 moles of and 3 moles of
.
Answer:
12.7mol Na.
Explanation:
Hello there!
In this case, according to the concept of mole, which stands for the amount of substance, we can recall the concept of Avogadro's number whereby we understand that one mole of any substance contains 6.022x10²³ particles, for the given atoms of sodium, we can calculate the moles as shown below:
Thus, by performing the division we obtain:
