Basketball is a tough game which requires more energy so for that reason you should eat healthy and nutritive food in order to maintain your health. You should eat the food from which about 55% of the calories comes from the food having high amount of carbohydrates.
NO₃⁻ is the polyatomic ion in this case.
Molar mass :
NaBr = 103 g/mol
Pb(NO3)2 = 331.20 g/mol
<span><span /><span>Balanced chemical equation :
</span></span>2 NaBr + 1 Pb(NO3)2 = 2 NaNO3 + 1 PbBr<span>2
</span><span>
2*103 g NaBr ------------> 1 * 331.20 g Pb(NO3)2
g NaBr -------------------> 311 g Pb(NO3)2
331.20 g = 2*103*311
331.20 g = 64066
mass ( NaBr ) = 64066 / 331.20
mass ( naBr) = 193,43 g of NaBr
hope this helps!.

2 C8H18 + 25 O2 = 16 CO2 + 18 H2<span>O
Above is properly balanced but as you want 1 mole. divide everything by 2
</span>C8H18 + 12.5O2 = 8CO2 + 9H2<span>O</span>
