Answer:
The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side.
Explanation:
How do you balance equations?
In general, however, you should follow these steps:
1. Count each type of atom in reactants and products.
2. Place coefficients, as needed, in front of the symbols or formulas to increase the number of atoms or molecules of the substances.
3. Repeat steps 1 and 2 until the equation is balanced.
This is the answer its very useful and very helpful
The minimum mass of NaHCO3 that must be added to the spill to neutralize the acid is 27.216 grams
<h3>calculation </h3>
write the balanced chemical equation
2NaHCO3 +H2SO4 → Na2SO4 +2H2O +2CO2
find the moles of H2SO4 = molarity x volume in liters
volume in liters = 27/1000=0.027 l
moles is therefore= 0.027 x6=0.162 moles
by use of mole ratio of NaHCO3: H2SO4 which is 2:1 the moles of NaHCO3=0.162 x2=0.324 moles
mass of NaHCO3= moles of NaHCO3 x molar mass of NaHCO3(84g/mol)
= 84g/mol x 0.324=27.216 grams
The force of the swing.
Hoped I helped, and please tell me if I am wrong.
