Answer:
Ca(OH)₂ + H₂SO₄ → CaSO₄ + H₂O
Explanation:
Chemical equation:
Ca(OH)₂ + H₂SO₄ → CaSO₄ + H₂O
Balanced chemical equation:
Ca(OH)₂ + H₂SO₄ → CaSO₄ + 2H₂O
The given reaction is double displacement reaction in which anion and cation of both reactant exchanged with each other. Calcium hydroxide react with sulfuric acid and form calcium sulfate and water.
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AD +CB
Answer:
c
Explanation:
the rate of a forward process must be exactly balanced by the rate of the reverse process.
Answer:
2KClO3 》》2KCl +3O2
C+ O2》》CO2
number of C moles
Required O2 moles (According to the mole ratio )
Relevant to the first equation, find the moles the KClO3, which is used to produce that amount of O2 moles
Now you can find the mass of KClO3
I mentioned the useful steps which can guide you to get the answer.
Explanation:
1. Mitosis is a process where a single cell divides into two identical daughter cells (cell division).
2. Mitosis is important because it plays an important part in the development of embryos, and it is important for the growth and developemet of our body as well.
3. The four phases of mitosis are: Prophase, metaphase, anaphase, and telophase.
4. Two gap phases (G1 and G2); an S (for synthesis) phase, in which the genetic material is duplicated.
5. During S phase all of the chromosomes are replicated.

Answer:
0.18 L
Explanation:
You can find the volume using the molarity ratio:
Molarity = moles / volume (L)
You can plug the given values into the equation and simplify to find the volume.
Molarity = moles / volume <----- Molarity ratio
2.5 M = 0.45 moles / volume <----- Insert values
(2.5 M) x volume = 0.45 moles <----- Multiply both sides by volume
volume = 0.18 L <----- Divide both sides by 2.5
