In balancing chemical equations, all you need to do is make it so that you have the same number of each element on both sides of the eqtn (if I have 5C on the left, I have to have 5C on the right — an element can’t magically appear or disappear); that being said:
(2)C2H6 + 7O2 ➡️ 6H2O + 4CO2
(12)HClO4 + P4O10 ➡️ 4H3PO4 + (6)Cl2O7
2N2 + (5)O2 + 2H2O ➡️ 4HNO3
(3)CaCl2 + 2Na3PO4 ➡️ (1)Ca3(PO4)2 + 6NaCl
4FeS + 7O2 ➡️ 2Fe2O3 + 4SO2
Answer:
13. A
14. C
Explanation: i tried my best
Explanation:
Because the solution only contains Na+ and Cl− ions, and water, and not the metal Na(s) . You cannot evaporate the water from the solution and hope to obtain anything but NaCl(s) .
.
Na(s) has an electron configuration of 1s^2 2s^2 2p^6 3s^1 , but Na+(aq) has an electron configuration of 1s^2 2s^2 2p^6 . That means they are not the same element, and thus, there is no straightforward way of extracting Na(s) from a NaCl (aq) solution
