balance the reaction, do not leave any fractions, dont leave anything blank, then answer the questions about the reaction
__1__ mo₂o₃ → __2__ mo + __3__ o₂
this is an __4__ reaction.
is this a redox reaction? (yes/no)__5__, because mo⁺³ is reduced to mo⁰, and because o₂⁻² is __6__ to o₂⁰.
will the reaction happen as it is written? (yes/no)__7__, because o₂ is very reactive and thus will not form. the reverse reaction would happen.

# Explanation:
## Step1: Balance the chemical equation
For the reaction $Mo_2O_3
ightarrow Mo + O_2$, we use the method of balancing atoms.
The number of $Mo$ atoms: on the left - hand side, there are $2$ $Mo$ atoms in $Mo_2O_3$. On the right - hand side, let the coefficient of $Mo$ be $x$.
The number of $O$ atoms: on the left - hand side, there are $3$ $O$ atoms in $Mo_2O_3$. On the right - hand side, let the coefficient of $O_2$ be $y$.
We want to find integers $a$, $b$, and $c$ such that $aMo_2O_3 = bMo + cO_2$.
Balancing $Mo$ atoms: $2a=b$. Balancing $O$ atoms: $3a = 2c$. Let $a = 2$, then $b=4$ and $c = 3$. So the balanced equation is $2Mo_2O_3
ightarrow4Mo + 3O_2$

## Step2: Determine the type of reaction
The reaction $2Mo_2O_3
ightarrow4Mo + 3O_2$ is a decomposition reaction ($U$) because a single compound ($Mo_2O_3$) breaks down into two or more simpler substances ($Mo$ and $O_2$)

## Step3: Check if it is a redox reaction
In $Mo_2O_3$, the oxidation state of $Mo$ is $+ 3$ ($2x+3\times(-2)=0$, $x = + 3$) and in $Mo$ it is $0$. The oxidation state of $O$ in $Mo_2O_3$ is $-2$ and in $O_2$ it is $0$. Since there is a change in oxidation states ( $Mo$ is reduced and $O$ is oxidized), it is a redox reaction ($Z$). $O$ in $O^{2 -}$ is oxidized ($DD$) to $O_2$ (oxidation state $0$)

## Step4: Determine if the reaction occurs as written
The reaction $2Mo_2O_3
ightarrow4Mo + 3O_2$ will not happen as written ($AA$) because $O_2$ is very reactive and the reverse reaction (synthesis of $Mo_2O_3$ from $Mo$ and $O_2$) is more favorable

# Answer:
1. $2$ (B)
2. $4$ (D)
3. $3$ (C)
4. $U$ (decomposition)
5. $Z$ (yes)
6. $DD$ (oxidized)
7. $AA$ (no)
