What is a decomposition reaction? A. Two reactants break apart and combine as new products

B. One reactant break down to form more than one product

C. One reactant replaces an element in another reactant

D. Two reactants combine to form a single ew product.

(The answer is B)

According to A pex, the answer is B.

Explanation:

Because its right.

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.

the answer is the first option

explanation:

just googled it m8. not that hard
