Answer:The frozen balloon shrank because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases.
Explanation: hope this will help
Place both breaking in a freezer at a temperature
Answer:
The website is inaccurate.
Explanation:
Remember, a chemical change is characterized by many things, but most commonly:
- A change in color, temperature or state.
- An irreversible change
- One or more new substances are formed
Rusting (Iron oxide) is a redox reaction (Oxidation-Reduction Reaction) where iron molecules come in contact with water and oxygen molecules. The iron molecules lose electrons, becoming oxidized, while oxygen gains electrons, becoming reduced.
Is rust reversable? (No)
Did the colour of the iron on the surface change? (Yes)
Did a new substance form? (Yes, Read above).
Hope I helped! Have a good day!
So C12 is the limiting reactant and P4 is the excess
Mass P4 consumed= 0.31 mol X 123.9 g/mol =38.41 g P4 consumed.
Hope i helped
