Hydrogen chloride or most commonly known as hydrochloric acid and
muriatic acid is a diatomic compound that consists of hydrogen and chlorine. It
is prepared industrially by the combustion of hydrogen, H2, in chlorine, Cl2.
H2 + Cl2 -> 2HCl. There are also many metallic chlorides that release
hydrogen chloride gas, HCl, when warmed with concentrated sulfuric acid, H2SO4.
Mostly, it is prepared by heating it with sulfuric acid and sodium chloride.
The reaction is NaCl + H2SO4 -> HCl + NaHSO4. Adding sulfuric acid enables the reaction to proceed further and it acts as a catalyst in the reaction.

Answer:
-1
Explanation:
According to this question, the oxidation state/number of H and O in C2H4O is +1 and -2 respectively.
The oxidation state of carbon in the compound can be calculated thus:
Where;
x represents the oxidation number of C
C2H4O = 0 (net charge)
x(2) + 1(4) - 2 = 0
2x + 4 - 2 = 0
2x + 2 = 0
2x = -2
Divide both sides by 2
x = -1
The oxidation number of C in C2H4O is -1.
PO4 anion has a 3- charge.A sodium cation , has a 1+ charge.Now , you have to think how many Na ions you need to fully neutralize the PO4 's 3- charge. Answer 3. That's because a molecule must have a neutral charge (a 0 charge). 3+(-3)=0.So , sodium phosphate has the formula Na3PO4.
Answer:
77
Explanation:
H2O needs 2 hydrogens and you have 154 so 154/2 is 77
thats the most you can do
