Mechanical to sound I’m pretty sure I’m sorry if it’s wrong :)
Na2SO4 is the salt that is produced.
If you look at the question, it asking which is produced so the answer must be on the product side of the reaction (to the right of the arrow).
You should also recognize that 2H2O is water, and water is not a salt.
Therefore the only other choice is Na2SO4.
D. The energy released or absorbed during the reaction
a heterogeneous mixture is simply any mixture that is not uniform in composition , it's a non-uniform mixture of smaller constituent parts and maybe D
Answer:
Explanation:
First, calculate the molar mass of NH4SO2. The molar mass can determine the number of moles. Then use Avogadro's number to calculate the number of molecules.
Key Steps:
Step 1. Calculate the molar mass of your compound
Step 2. Divide 2.3 grams by the molar mass of NH4SO2, this gives us moles
Step 3. Multiply by Avogadro's number (6.02x10^23) this gives you molecules.
