Answer:
2C₈H₁₈(g) + 25O₂(g)→16CO₂(g) + 18H₂O
Explanation:
To balance an equation, the moles of one element on one side of the equation should be the same as those on the other side of the equation. This is because (as a law of thermodynamics), in a chemical reaction, the matter is not destroyed nor created - atoms are only rearranged.
The chemical purpose of heating the MnSO4⋅H2O is to eliminate water with the formation of new compounds.
<h3>Dehydration reactions</h3>
Dehydration reaction is a type of chemical reaction that involves the removal of water which would eventually lead to the formation of a new compound.
The molecule of MnSO4⋅H2O contains a molecule of water(H2O). After heating of the molecule, water is lost giving rise to the dry compound MnSO4.
Other examples of dehydration reactions are:
- Reactions that produce acid anhydrides.
- Reactions that involve the production of polymers.
- Reaction of sucrose with concentrated sulfuric acid
Therefore, the chemical purpose of heating the MnSO4⋅H2O is to eliminate water with the formation of new compounds.

Phosphorus 31. because the mass of sulfur 32 minus the number of protons 16 = 16 neutrons and the mass of phosphorus 31 minus the number of protons 15 = 16 neutrons
Final answer: phosphorus 31
2H3PO4 + 3Ca(OH)2 ➡ Ca3(PO4)2 + 6H2O.
Hence salt formed is Ca3(PO4)2.
Hope this helps, have a nice day!
