Answer:
The balloon quickly becomes inflated because it is filled with CO2 gas
Explanation:
Once the vinegar and baking soda are mixed, a chemical reaction occurs as follows;
NaHCO3+CH3COOH→CH3COONa+H2O+CO2.
Once this reaction occurs, the balloon becomes inflated because it is now filled with CO2 gas.
If the filled balloon is punctured at any point, CO2 gas escapes from it.
Answer:
yes. For a pop bottle biome to be self sustaining it needs a water cycle, mineral cycle, solar energy flow, and a balance.

Answer:

decomposition reaction
Explanation:
The reaction equation is given as:
_Ca(OH)₂ → _CaO + _H₂O
This reaction is a decomposition reaction in which a single reactant breaks down to give two or more products.
To balance the equation, we assign variables a, b and c, then we use a mathematical approach to solve the problem;
aCa(OH)₂ → bCaO + cH₂O
Conserving Ca : a = b
O: 2a = b + c
H: 2a = 2c
let a = 1, b = 1 , c = 1
