Answer:
Option 4) equal to
Explanation
When having a reversible reaction, this reaction (or system) reaches the balnace, it is observed that relative quantitives for all compounds (this is, reactives and products), remain constant
The species concentration does not change over time, and; in the same way; there are no physical changes as time goes by
For example, for the following reaction :
aA + bB ⇔ cC + dD
Compounds A and B react to give products C and D. The two way arrows means that this systme has reached the balance (is in equilibrium)
Answer:
Zr. You should be able to see it on a periodic table.

Answer:
Valency is the combining power of an element.
There are two types of valency - Electrovalency and Covalency.
- <u>Electrovalency</u>: It is equal to the number of electrons lost or gained by atom to form ion.
- <u>Covalency</u>: It is the number of electron taking part in the formation of shared pairs.

Answer:
C
Explanation:
Assuming you had a few typos in the equations, I would say C
I am going to assume the reaction
_C2H6 + _O2 → _CO2 + _H2O
Right now, there is enough hydrogen to make 3 water molecules, but since oxygen comes in groups of 2, it wouldn't work.
Therefore, we need 2 ethane molecules.
2C2H6 + _O2 → _CO2 + _H2O
Then balance the right side with the carbons and hydrogens
2C2H6 + _O2 → 4CO2 + 6H2O
So we need 4 O2's in carbon dioxide and 3 O2's in water (Since water uses 1 oxygen molecule per 2 hydrogens). Hence we will need 7 oxygens
2C2H6 + 7O2 → 4CO2 + 6H2O
And assuming errors in the typing, C should be the answer (if this matches)
