Just multiply 9.5 by Avogadro's number. You get 5.72 x 10^24 atoms.
It should be the digestive system as it absorbs the nutrients of the food into your body.
The sum of all coefficients = 7
<h3>Further explanation</h3>
Given
The word equation
Required
The sum of all coefficients
Solution
The chemical equation can be expressed in terms of:
- word equation
- skeleton equation
- balanced equation
Convert the word equation into a chemical equation(skeleton) :
Ga + Cl₂ → GaCl₃
Balanced equation
2Ga + 3Cl₂ → 2GaCl₃
The sum of all coefficients :
= 2+3+2
= 7
<span> 2KCl(s) => 2K(s) + Cl2(g) </span>is correctly balanced. Becuase <span>2 K, 2 Cl on the left, and 2 K, 2 Cl on the right.</span>
