Answer:
2H3PO4 + 3Ca(OH)2 = Ca3(PO4)2 + 6H2O
3CaO + P2O5 = Ca3(PO4)2
Answer:
Metals are found to the left of the zigzag line on the periodic table. B. Nonmetals Nonmetals are found to the right of the zigzag line on the periodic table.
Explanation:
Answer:
D (Decomposition)
Explanation:
This reaction is a decomposition reaction because one substance (NaNO3) is being separated into two substances (NaNO2 and O2). Alternatively, you could use the process of elimination. The reaction can't be single/double replacement because there's only one reactant, it can't be synthesis because substances are being broken down, not formed, and it can't be combustion because O2 is a product, not a reactant, and CO2 and H2O aren't being produced, as is common with combustion reactions.

Definitely, the correct answer is option B. When Ca(OH)2 is added into a beaker, the solution will turn into pink when the indicator phenolphthalein is added. This is due to the hydroxide ions from the calcium hydroxide dissolved in water. The compound dissociates into calcium ions and hydroxide ions.
