Explanation:

On the left you have:
Na: 1
Br: 2
On the right you have:
Na: 1
Br: 1
To get the Br to be the same on both sides, you would multiple the NaBr by 2. Then, you will have 2 Na so you put a coefficient of 2 in front of the Na aswell.
Force is equal to mass multiplied by acceleration, therefore
F=ma
m=2569.6 kg
a=4.65m/s^2
<span>therefore F=2569.6*4.65=11948.6 (correct to 1 d.p.)</span>
Answer:
171 moles of sodium chloride
Explanation:
Number of moles = mass/molar mass
Molar mass of sodium chloride = 58.5 g/mol
mass of sodium chloride = 10 Kg or 10,000 g
Now, to obtain the number of moles of sodium chloride;
Number of moles = 10,000 g/58.5 g/mol
Number of moles = 171 moles of sodium chloride
