Answer:
21.02moles of KBr
Explanation:
Parameters given:
Number of moles BaBr₂ = 10.51moles
Complete reaction equation:
BaBr₂ + K₂SO₄ → KBr + BaSO₄
Upon inspecting the given equation, we find out that the atoms are not balanced on both sides of the equation:
The balanced equation is:
BaBr₂ + K₂SO₄ → 2KBr + BaSO₄
From the equation:
1 mole of BaBr₂ produces 2 moles of KBr
∴ 10.51 moles of BaBr₂ will yield (2 x 10.51) moles = 21.02moles of KBr

Answer:</h3>
H+ contains 1 proton, 0 neutrons, 0 electrons.
<h3>
Explanation:</h3>
- An atom is the smallest particle of an element that can take part in a chemical reaction.
- Atoms are made of sub-atomic particles neutrons and protons found in the nucleus and electrons found in the energy levels.
- A hydrogen atom contains 1 proton and 0 neutrons in the nucleus and 1 electron in the energy levels.
- A hydrogen atom loses an electron to form an ion with 1 proton, 0 neutron and 0 electron.
Answer:
7.28 mol Na2SO4
Explanation:
Since it is already in moles, all we have to do is use a molar ratio
A molar ratio is the proportions of reactants and products using the balanced equation. When writing a mole ratio, the given information must cross out with the right thing.
7.28 mol H2SO4 * 1 mol Na2SO4/1 H2SO4 = 7.28 mol Na2SO4
*notice how the H2SO4 crosses out
