hydrosulfic acid (this is not correct)
It is hydrosulfuric acid (All acids containing sulfur or a sulfur-containing group, use the whole word "sulfur" rather than the stem "sulf").
Hydrogen selenide, with formula H2Se, is formed from reacting hydrogen and selenium.
(aq) is from aqueous, a substance in solution.
'aq' , sometimes subscripted at the right of the element's symbol: eg. Na+aq
This is a precipitation chemical reaction.
Na2S(aq) + ZnCl2(aq) --> 2NaCl(aq) + ZnS(s)
It is actually HCl(aq) Its chemical name is Hydrochloric acid
Aqueous, usually written as (aq) after the name of whatever is dissolved in it.
CH3COOH(aq) has more than one chemical name. It is acetic acid, also known as ethanoic acid. The (aq) simply means an aqueous solution.
H2Se is a stronger acid than H2S. The bond energy of H2Se is less than H2S, making it easier for the hydrogen atom to leave the molecule. Therefore, H2Se is expected to be a stronger acid than H2S.
The formula is for potassium chloride in water solution.
If you think to C2H2 O4 this the oxalic acid.
Hydrogen selenide, with formula H2Se, is formed from reacting hydrogen and selenium.
The bond in H2Se is polar.
Equilibrium:NO2- (aq) + H2O HNO2 (aq) + OH- (aq)
NH3 (aq) + H2O (l) --> NH4+ (aq) + OH- (aq)
ability to convert among names and formulas for chemical compounds is crucial to ....HF(aq) + LiOH(aq) → H2O(l) + LiF(aq) c. H3PO4(aq) + 3LiOH(aq) → 3H2O(l) + Li3PO4(aq) d. Fe(OH)3(s) + 3HNO3(aq) → Fe(NO3)3(aq) + 3H2O(l). Exercise ...that all i can say and that what i think :)
Definition: An ionic equation is a chemical equation where the electrolytes in aqueous solution are written as dissociated ions.Examples:Ag+(aq) + NO3-(aq) + Na+(aq) + Cl-(aq) → AgCl(s) + Na+(aq) + NO3-(aq) is an ionic equation of the chemical reaction:AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq)
