I've been given some really hard Chemistry homework, and I can't fill in the blanks. I would really apprechiate some help, if you can!
These are the equations:

Zinc + Hydrochloric acid = ________ chloride + water

Magnesium + Sulphuric acid = _________ sulphate + water

Hydrochloric acid + Calcium carbonate = ________ chloride + water + _________ ______

If you can help thank you sooo much! And if you can't, thank you anyway for taking the time to read this!
