Answer:
Oxidation, Reduction
Explanation:
A redox reaction is a short form for reduction-oxidation.
Reduction is a term which means that electron is gained while oxidation is a term which means that electron Is lost.
The species that gain electron is known as the oxidizing agent while the species losing electrons is known as the reducing agent
Answer:
8
Explain
H: Ignoring the coefficient, we know there's 5+3=8 atoms
Explanation:
the molar mass of the compound is 1502g/mol
Answer: HBr has the lowest rate of effusion at a given temperature.
Explanation: The effusion rate usually increases with increase in temperature because the kinetic energy of the gaseous molecules increases. But it was not true for gases having heavier mass. This was explained by Graham's Law.
Graham's Law states that the rate of effusion of a gas is inversely proportional to the square root of its molecular weight.
We are given different gases with different Molecular masses. The gas having larger Molecular mass will have the lowest rate of effusion.
Mol. Mass of = 80 g/mol
Mol. Mass of = 16 g/mol
Mol. Mass of = 17 g/mol
Mol. Mass of HBr = 81 g/mol
Mol. Mass of HCl = 36 g/mol
As, Mol. mass of HBr is the highest, so its rate of effusion will be the lowest.
