Balance the following equations <br>1.Na+HCI=NaCI+H2<br>2.Mg+O2=MgO​
liberstina [14]

Answer:

1. 2Na + 2HCl = 2NaCl =H2

2. 2Mg + O2 = 2MgO

Explanation:

make sure that the number of atoms of each element is the same on each side of the equation  

1. 2Na + 2HCl = 2NaCl =H2

<em><u>on LHS of equation,</u></em>

Na = 2

H = 2

Cl =2

<em><u>On RHS of equation, </u></em>

Na=2

H= 2

Cl =2

2. 2Mg + O2 = 2MgO

<em><u>on LHS of equation,</u></em>

Mg = 2

O2 = 2

<em><u>On RHS of equation, </u></em>

Mg = 2

O2 = 2

The half-life of hydrogen-3 (tritium) is approximately 12 years. In how many years will half of a 20-gram sample decay by beta r
anyanavicka [17]
<h3>Answer:</h3>

12 years

<h3>Explanation:</h3>

We are given;

Half life of hydrogen-3 is 12 years

Initial mass of Hydrogen-3 is 20 grams

Final mass will be 10 g because we are told half of the sample will decay.

To find the time taken for the decay we need to know what half life is;

  • Half life is the time taken for a radioactive isotope to decay to half its original amount.
  • Using the formula;

Remaining mass = Original mass × 0.5^n

n = number of half lives

therefore;

10 g = 20 g × 0.5^n

0.5 = 0.5^n

n = log 0.5 ÷ log 0.5

  = 1

But, 1 half life is 12 years

Therefore, the time taken is 12 years
