Thermal decomposition
The thermal decomposition of 1.6608 grams of MgSO4 x H20 produces 1.4446 grams of a product in a well behaved reaction. There are two possibilites:MgSO4 x H2O (s) -----> MgSO4 (s) + H20 (g)MgSO4 x H2O (s) -----> MgO (s) + SO3 (g) + H20 (g)I have to find the answer by filling out a chart. The only info provided is the mass of the MgSO4 x H20 which is 1.6608 grams.Substance-----Formula Weight-----Moles-----Mass(g)MgSO4 x H20MgSO4MgO

I was wondering if someone could help me with problems on my
test my teacher allows me to correct the wrong ones then give them
back for half credit. Along with the correct answer for each I’d
like to know why the answer I chose is wrong what is the correct
answer and why it is the correct answer. The marked red problems
are the incorrect problems.

I need help with part 6! All the other questions are correct so far! Thank you! In Part 1 of Lab 2 you will make and standardize a solution of NaOH(aq). Suppose in the lab you measure the solid NaOH and dissolve it into 100.0 mL of water. You then measure 0.1995 g of KHP (KC8H5O4, 204.22 g/mol) and place it in a clean, dry 100-mL beaker, and then dissolve the KHP in about 25 mL of water and add...
