Explanation:
A reversible reaction is a reaction which results in the formation of products which gives back reactants. Therefore, it is said that a reversible reaction occurs in both forward and backward direction.
Thus, it can be concluded that a reversible reaction is a reaction that takes place in the both directions . If the reaction were to equilibrium, the rate of the forward reaction would equal that of the reverse reaction.equilibrium.
HNO3 is a strong acid while HBrO is weak acid.
Therefore we ignore the presence of the weak acid such that we consider the pH of the strong acid.
Therefore; since pH= - log (H+)
Hence pH= -log 0.18
= 0.745
Thus the pH of the mixture is 0.745
Answer: because atoms have more protons
Explanation: just took the test
Answer:
a. Sally did not take account the atoms of the compounds, because she only summed Al + O and in the oxide, we have 2 mol of Al and 3 mol of O
b. The conversion factor that Jacob did, was wrong.
Moles must be divided by moles, so they can be cancelled. The correct conversion factor is:
9.45 mol . 102 g / 1 mol = 963.9 g
Explanation:
Al₂O₃ → Aluminum oxide
We determine the molar mass:
Molar mass Al . 2 + Molar mass O . 3
27 g/mol . 2 + 16 g/mol . 3 = 102 g/mol

I really cant show any work but it's 0.00043045
