Question

balance the reaction, do not leave any fractions, dont leave anything blank, then answer the questions about the reaction
1ca(oh)₂ +2h₃po₃ →3ca₃(po₃)₂(s) +4h₂o
this is an 5 reaction and also a 6 reaction (use the order given in the answers).
is this a redox reaction?(yes/no)7, because neither ca⁺², oh⁻¹, h⁺¹, nor po₃⁻³ change oxidation state.
will the reaction happen as it is written? (yes/no)8, because acids and bases are reactive, the products are stable, and one product is a solid. the reverse reaction would not happen.
a. 1 b. 2 c. 3 d. 4 e. 5 f. 6 g. 7 h. 8
i. 9 j. 10 k. 12 l. 14 m. 16 n. 18 o. 20 p. 21
q. 24 r. 26 s. 28 t. synthesis u. decomposition
v. single displacement w. double displacement x. neutralization
y. combustion z. yes aa. no bb. reactive cc. stable
dd. oxidized ee. reduced

Explanation:

Step1: Balance Ca atoms

$$3Ca(OH)_2 + H_3PO_3 \to Ca_3(PO_3)_2 + H_2O$$

Step2: Balance P atoms

$$3Ca(OH)_2 + 2H_3PO_3 \to Ca_3(PO_3)_2 + H_2O$$

Step3: Balance H and O atoms

$$3Ca(OH)_2 + 2H_3PO_3 \to Ca_3(PO_3)_2 + 6H_2O$$

Answer:

1. X. neutralization
2. W. double displacement
3. AA. no
4. Z. yes
