If you start a chemical reaction with 5 atoms of hydrogen, how many hydrogen atoms will you have when it is finished? Group of a
mote1985 [20]

Answer:

5 atoms

Explanation:

According to the law of conservation of mass, "matter is neither created nor destroyed in the cause of a chemical reaction".

We finish with what we start with in a chemical reaction. Although new species might form, the number of atoms on both sides of the expression will still be maintained.

All chemical reactions obey this law of conservation.

Sedaia [141]
<span>1.18 x 3 = 3.55 </span>
find  ratio of F to F in each compound
.   according to law of multiple proportions  that the masses of one element which combine with a fixed mass of the second element are in a ratio of whole numbers.
now  F is  "one element" and S has  "fixed mass",
the ratio of F6 to Fx = 3:1 
<span>thats why  x= 2
there is less F in SFx
  the ratio is 3:1.

Which of the following is the correctly balanced chemical equation for the reaction of Ca(OH)2 and HNO3?
sattari [20]

Explanation:

The reaction between calcium hydroxide and nitric acid is as follows.

  Ca(OH)_{2} + HNO_{3} \rightarrow Ca(NO_{3})_{2} + H_{2}O

Number of reactant atoms are as follows.

  • Ca = 1
  • O = 4
  • H = 3
  • N = 1

Number of product atoms are as follows.

  • Ca = 1
  • O = 4
  • H = 2
  • N = 3

To balance the given chemical equation, multiply HNO_{3} by 2 on reactant side and multiply H_{2}O by 2 on the product side.

Therefore, the balanced chemical equation will be as follows.

    Ca(OH)_{2} + 2HNO_{3} \rightarrow Ca(NO_{3})_{2} + 2H_{2}O
