The balanced equation for the neutralisation reaction is as follows
Ca(OH)₂ + H₂SO₄ ---> CaSO₄ + 2H₂O
stoichiometry of Ca(OH)₂ to H₂SO₄ is 1:1
equivalent number of acid reacts with base
number of H₂SO₄ mol reacting - 2 mol
according to molar ratio of 1:1
number of Ca(OH)₂ mol = number of H₂SO₄ moles
therefore number of Ca(OH)₂ moles required - 2 mol
The chemical formula of manganese (Il) phosphate is Mn3(PO4)2, which is option 2.
<h3>What is chemical formula?</h3>
The chemical formula of a compound is the notation indicating the number of atoms of each element present in a compound.
The chemical formula of a compound tells us the type of elements in the compound, the number atoms of each element in the compound and in what proportion these elements are present.
According to this question, manganese II phosphate has the chemical formula of Mn3(PO4)2.
This chemical formula shows that it posseses the following:
- 3 manganese atoms
- 2 phosphorus atoms
- 8 oxygen atoms

Hi I'm in Chemistry too this year,
I believe D is correct because usually physical changes are things like density, color or quantity.
Answer:Protons, neutrons, and electrons are the three main subatomic particles found in an atom. Protons have a positive (+) charge. An easy way to remember this is to remember that both proton and positive start with the letter "P." Neutrons have no electrical charge.
Explanation:
Answer:
You'll experience a grater deviation
Explanation:
<em>You'll experience a greater deviation in your measurements, meaning your measures will have a bigger difference between them, and the greater these deviations the less accurate will be the measuring.</em> This happens mainly because you're not replicating the measurement with the exact same conditions, in one of them you'll have an extra mass from the water.
I hope you find this information useful and interesting! Good luck!
