Answer:
0.5475 grams of stomach acid, HCl, are neutralized by one tablet of Tums.
Explanation:
Mass of calcium carbonate = 750.0 mg = 0.750 g
Moles of calcium carbonate =
According to reaction , 1 mole of calcium carbonate reacts with 2 moles pf HCl.
Then 0.0075 moles of calcium carbonate will recat with:
of HCl.
Mass of 0.015 mol of HCl:
0.015 mol × 36.5 g/mol = 0.5475 g
0.5475 grams of stomach acid, HCl, are neutralized by one tablet of Tums.
Answer:
Mg + 2H₂O —> Mg(OH)₂ + H₂
Explanation:
Mg + H₂O —> Mg(OH)₂ + H₂
The above equation can be balance as illustrated below:
Mg + H₂O —> Mg(OH)₂ + H₂
There are 2 atoms of H on the left side and a total of 4 atoms on the right side. It can be balance by writing 2 before H₂O as shown below:
Mg + 2H₂O —> Mg(OH)₂ + H₂
Now, the equation is balanced
