Write formation reactions for the following. (You must include the states of matter for each atom or compound)

A. Ca(NO3)2 (s)
B. CH3OH (l)
C. NaClO4(s)

Ca(s) + N2(g) + 3O2(g) ==> Ca(NO3)2(s)

C(s,graphite) + 2H2(g) + 1/2 O2(g)==> CH3OH(l)

A. The formation reaction for Ca(NO3)2 (s) can be written as:

Ca(s) + 2 HNO3(l) → Ca(NO3)2(s) + H2(g)

B. The formation reaction for CH3OH (l) can be written as:

C(s) + 2 H2(g) + 1/2 O2(g) → CH3OH(l)

C: The formation reaction for NaClO4 (s) can be written as:

Na(s) + Cl2(g) + 4 O2(g) → NaClO4(s)

To write the formation reactions for the given compounds, we need to examine the elements present and determine the combination that leads to the formation of the compound. Here are the formation reactions for each compound along with their states of matter:

A. Ca(NO3)2 (s)
To form calcium nitrate, Ca(NO3)2, we need calcium (Ca) and nitrate (NO3). Calcium is a metal, generally found in the solid state, and nitrate is a polyatomic ion containing nitrogen (N) and oxygen (O). Since the question specifies that the compound is in the solid state, the formation reaction would be as follows:

Ca (s) + 2 NO3 (g) → Ca(NO3)2 (s)

B. CH3OH (l)
CH3OH is the chemical formula for methanol. It consists of carbon (C), hydrogen (H), and oxygen (O). Carbon is typically present in the solid state, hydrogen exists as a gas, and oxygen is a diatomic gas. Since the question specifies that the compound is in the liquid state, the formation reaction would be as follows:

C (s) + 2 H2 (g) + O2 (g) → CH3OH (l)

C. NaClO4 (s)
Sodium perchlorate, NaClO4, is composed of sodium (Na), chlorine (Cl), and oxygen (O). Sodium is a metal that is typically found in the solid state, chlorine is a diatomic gas, and oxygen is also a diatomic gas. Since the question specifies that the compound is in the solid state, the formation reaction would be as follows:

2 Na (s) + Cl2 (g) + 4 O2 (g) → 2 NaClO4 (s)

Remember that the formation reactions represent the combination of elements to create a compound and the states of matter may vary depending on the experimental conditions.
