What would the [OH-] of a solution that has a pOH of 2.7 be?
Answer:
The [OH⁻] of a solution that has a pOH of 2.7 will be 2*10⁻³
Explanation:
The pOH (or potential OH) is a measure of the basicity or alkalinity of a solution.
pOH indicates the concentration of hydroxyl ions [OH-] present in a solution. In this way, pOH is defined as the negative logarithm of the activity of hydroxide ions, that is, the concentration of OH- ions:
pOH= -log [OH⁻]
In this case, pOH has a value of 2.7. Replacing:
2.7= -log [OH⁻]
and solving:
[OH⁻]=10⁻² ⁷
you get:
[OH⁻]≅ 2*10⁻³
The [OH⁻] of a solution that has a pOH of 2.7 will be 2*10⁻³

How many molecules are in 7.9 mol of H202
Answer: There are [tex]47.6\times 10^{23}[/tex] molecules in 7.9 mol of [tex]H_2O_2[/tex]
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
1 mole of [tex]H_2O_2[/tex] molecule contains = [tex]6.023\times 10^{23}[/tex] molecules
Thus 7.9 mole of [tex]H_2O_2[/tex] molecule contains = [tex]\frac{6.023\times 10^{23}}{1}\times 7.9=47.6\times 10^{23}[/tex] molecules
Thus there are [tex]47.6\times 10^{23}[/tex] molecules in 7.9 mol of [tex]H_2O_2[/tex]
What mass of MnCl2 is produced when 0.091 g of Cl2 is generated?
The mass of MnCl2 that is produced when 0.091 g of Cl2 is generated is 0.16 g.
Molar mass of MnCl₂ = 55 + 35.5(2) = 126 g/mol
Molar mass of Cl₂ = 35.5(2) = 71 g/mol
If 71 g of Cl₂ gives 126 g of MnCl₂
0.091 g of Cl₂ will give ? of MnCl₂
cross multiply
mass of MnCl₂ produced = 0.091 × 126 / 71
mass of MnCl₂ produced = 11.466 / 71
mass of MnCl₂ produced = 0.16149295774
mass of MnCl₂ produced ≈ 0.16 g

25.0 g Fe2CO3 reacts with 20.0 g CO in the reaction below. What is the limiting reactant and what best explains why is this reactant limiting?
Fe2CO3 + CO --> 2Fe + 2CO2
Answer:
In a chemical reaction, reactants that are not used up when the reaction is finished are called excess reagents. The reagent that is completely used up or reacted is called the limiting reagent, because its quantity limits the amount of products formed. It represents a reaction of a metal and a diatomic gas chlorine.
