Answer:
An electron is in a region outside the nucleus, <u>has less mass than a proton and has a negative charge.</u>
Explanation:
Electrons are considered as a negatively charged particle, as they are surrounded by the kind of invisible force called the electrostatic force.

Answer:
The energy transported by a wave is directly proportional to the square of the amplitude. So whatever change occurs in the amplitude, the square of that effect impacts the energy. This means that a doubling of the amplitude results in a quadrupling of the energy.
Answer:
The temperature of the solute/solvent without any external effect would decrease.
Explanation:
As the bonding between the solute particles is really strong, therefore a large amount of energy is required to overcome these forces. So that the new bonding between the solute and solvent is created.
In order to achieve this, there will be a lot of energy required and that is through the heating process. So the solution will require energy so the solute will dissolve fully either by provision of external force i.e stirring or by heating.
Explanation:
2 C4H8O + 11 O2 —> 8 CO2 + 8 H2O
