el hidróxido es hidrógeno unido covalentemente al oxígeno. Es un anión y tiene carga negativa.
Answer:
The generic equation for a combustion reaction is AB + O2 à AO + BO
Explanation:
The reaction equation is: CaF₂ + H₂SO₄ → 2HF + CaSO₄
The molar ratio between fluorite and hydrogen fluoride is 1 : 1.
The moles of fluorite supplied are:
Moles = 15 / 78.07 Moles = 0.200
The moles of hydrogen fluoride produced will be 0.2.Now, we may use the ideal gas equation to determine the temperature:
PV = nRT T = PV/nR
T = (875 * 8.63) / (0.2 * 62.36)
T = 605.45K
The temperature will be 331.85 °C which is required to store the gas in an 8.63-L container at 875 torr.

Answer:
Molar mass = 99 g/mol
Explanation:
Phosgene contains carbon, oxygen and chlorine atoms. Its molecular formular is; COCl2
The molar mass is given as the sum off the individual atomic mass of the elements in the compound.
Molar mass = C + O + 2Cl
Molar mass = 12 + 16 + 2(35.5)
Molar mass = 99 g/mol
