Answer:
The new volume of the balloon is .
Explanation:
Initial volume of a balloon is 417 cm³
The temperature decreases from 278 K to 231 K.
It is required to find the new volume of the balloon if the pressure is constant pressure. At constant pressure, volume is directly proportional to the temperature. So,
i.e.
V₂ is final volume.
So, the new volume of the balloon is .
Answer:
exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.”
Answer:
Ionic bonding is the complete transfer of valence electron(s) between atoms and is a type of chemical bond that generates two oppositely charged ions. By losing those electrons, these metals can achieve noble-gas configuration and satisfy the octet rule. ...

Explanation:</h3>
- Balancing chemical equations involves putting appropriate coefficients on the products and reactants to ensure the number of atoms of each element are equal on either side of the equation.
- Balancing chemical equations makes them obey the law of conservation of mass in chemical equations.
- In this case; to balance the first equation, we put coefficients 2, 3, 1 and 6 on the equation.
- That is, the balanced equation will be;
2GaBr₃ + 3Na₂SO₃ → Ga₂(SO₃)₃ + 6NaBr
- To balance the second equation, we put coefficients 3, 2, 3 and 1 respectively.
- Thus, the balanced chemical equation will be;
3SnO + 2NF₃ → 3SnF₂ + N₂O₃
