A compound with the chemical formula H2SO is not known.
Water (H2O) contain two elements.
Sulfurous acid (H2SO3) contain three elements.
...etc.
The sum of the coefficients of the chemical equation SF4 + H2O + H2SO + HF is 1 + 2 + 1 + 1 = 5.
NaCl has two elements: sodium (Na) and chlorine (Cl).
Aluminum has 13 elements.
Iodine has 53 elements.
Sulfur has 16 elements.
sulfuric acid
There are 15 moles of ammonia sulfate in the reaction of 30.0 mol of NH3. This goes from the formula 2 NH3 H2so take away (NH4)2So4.
There are 6.022 x 1023 molecules of hydrogen in 1 mole of H2so there are 6.022 x 1020 molecules in 1/1000 ( one thousandth) of a mole.
This is a neutralization reaction:2 NH4OH + H2SO4 = (NH4)2SO4 + 2 H2O
118 elements
The sum of the coefficients of the chemical equation SF4 + H2O + H2SO + HF is 1 + 2 + 1 + 1 = 5.
There are 118 elements on the periodic table.
92 elements
NaCl has two elements: sodium (Na) and chlorine (Cl).
This question is a little ambiguous. If you mean 'how many elements have mass,' the answer is 'all elements have mass.' There are 117 known elements, and scientists theorize that there may be as many as 130 or more.
