Answer:
Can you tell me the question in the comments on this answer or like how you do it then ill answer you in the comments under this answer
A) Magnesium Chloride
Mg is the symbol of Magnesium and Cl is the symbol of chlorine ( but when Cl is a compound it will be Choride)
Explanation:
A chemical change is a change in which a new kind of substance is produced. Such changes are always accompanied by energy changes.
They are mostly reversible.
Some examples of such reactions are combustion, rusting of iron, precipitation, rancidity of butter, souring of milk.
- There might be some little change in mass
- It requires a considerable amount of energy
Explanation:
Non-metals are the species which tend to gain electrons from a donor atom in order to attain stability.
Therefore, when a non-metal reacts with another non-metal then there will always be formation of a covalent bond. As covalent bonds are formed due to sharing of electrons.
For example,
is formed by sharing of electrons.
On the other hand, when a non-metal reacts with a metal then there will be formation of an ionic bond.
For example, LiCl is formed by transfer of electron from Li to Cl atom.
Thus, we can conclude that atoms of most non-metals share electrons and become bonded together into a molecule.
Start with the 19.7 mol HNO3. use dimensional analysis to correctly convert from mol HNO3 to gram H2O. so, it should look similar to 19.7 mol HNO3 x (2 mol H2O/6 mol HNO3) x (18 g H2O/1 mol H2O)
the first parenthesis’ numbers were received from the balanced equation (for every 6 mol HNO3, 2 mol H2O formed). the second is converting from moles to grams by using the molar mass of H2O (1+1+16). you should get 709.2/6. once you divide those, the answer should be 118.2 g H2O. I’m not sure if your computer requires you to use the exact answer or stop at the correct number of significant digits, but if it does then it might just be 118. g H2O.
