Answer:
DOUBLE DISPLACEMENT (mutual exachange of ions in aqueous form)
Ca is more reactive than Fe
hence it will displace Fe from ferrous nitrate solution and form Calcium Nitrate and Ferrous Sulphate will be formed
GOOD LUCK WITH THE FUTURE! :)
Take what you are given so 0.457g divide this by the molar mass (calculate this by taking the atomic weight of Na and Cl and add them together 23+35).
So 0.457gNaCl divide by (58g NaCl) = .0078 mol Nacl
1. c
2. It resembles the crystalline structure of ice
3. It should be eco-friendly
4. Similar- still falls in rain or snow when the cloud is full enough
Different- adding chemicals to quicken the process, not waiting for it to happen naturally
5. Droughts- plants dying, no crops- no food
The answer is: emitted gas is carbon dioxide (CO₂).
Neutralization is is reaction in which an acid (in this example vinegar or acetic acid CH₃COOH) and a base (in this example soda)
Balanced chemical reaction of vinegar and antacid:
CH₃COOH(aq) + NaHCO₃(aq) → CH₃COONa(aq) + H₂O(l) + CO₂(g).
Sodium acetate (CH₃COONa) is a salt.
Sodium bicarbonate (NaHCO₃) is an antacid. Sodium bicarbonate is the active ingredient in baking soda.
