Abalanced chemical equation indicates both the number of particles of reactants and products and the number of
a. orbits.
c. nuclei.
b. electrons.
d. moles

Option (d) is the correct answer.

Explanation:

A chemical reaction equation that shows same number of reactants and products is known as a balanced chemical equation.

For example,

Here, number 2 placed before the sodium (Na) atoms depicts that 2 moles of sodium reacts with 1 mole of chlorine to give 2 moles of sodium chloride salt.

Therefore, in a balanced chemical reaction equation number of moles are also equal on both reactant and product side.

Thus, we can conclude that a balanced chemical equation indicates both the number of particles of reactants and products and the number of moles.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

if you mean hydrogen and oxygen then water is the product
