HCl + NaHCO3 = NaCl + H2O + CO2
We have 0.033*0.2 = 0.0066 mol of Hcl
According to reaction we need the same amount of NaHCO3
M(NaHCO3) = 23+1+12+48=84g/mold
m = 0.0066mol * 84g/mol = 0.5544g

Answer:
unsaturated solution
Explanation:
This solution is made by the coffee, which is the solvent and the sugar, which is the solute. The solute dissolves in the solvent.
Sugar starts to precipitate because it cannot dissolve anymore. This means that the solution at the equilibrium point and is saturated. Since more coffee or solvent is added, the solution will now be able to dissolve more sugar. This means that the solution is unsaturated
What are the elements so i can help?????
Answer:
CH₄ + 2O₂ –> CO₂ + 2H₂O
The coefficients are: 1, 2, 1, 2
Explanation:
CH₄ + O₂ –> CO₂ + H₂O
The above equation can be balance by as follow:
CH₄ + O₂ –> CO₂ + H₂O
There are 4 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 2 before H₂O as shown below:
CH₄ + O₂ –> CO₂ + 2H₂O
There are 2 atoms of O on the left side and a total of 4 atoms on the right side. It can be balance by writing 2 before O₂ as shown below:
CH₄ + 2O₂ –> CO₂ + 2H₂O
Now, the equation is balanced.
The coefficients are: 1, 2, 1, 2
