Answer: acid react with metals to form H2.
Explanation: metals which are more electropositve than hydrogen will always displaced hydrogen from acids. The equation below show how hydrogen is displaced from acid
Zn + 2HCl -—> ZnCl2 + H2

Answer:
i also had this question:P
Explanation:
Answer:
26.5 g
Explanation:
First we convert 100.0 mL to L:
- 100.0 mL / 1000 = 0.100 L
Now we <u>calculate how many moles of sodium carbonate are needed</u>, using the <em>definition of molarity</em>:
- Molarity = moles / liters
- moles = molarity * liters
- 2.5 M * 0.100 L = 0.25 mol
Finally we <u>convert 0.25 moles of sodium carbonate into grams</u>, using its <em>molar mass</em>:
- 0.25 mol * 106 g/mol = 26.5 g
