Answer:
A
The nuber of each one should be same
The two compounds shown indeed have tha same molecular formula, C5 H11 NO2. One of the molecules has a group NH2 and a group COOH, the other molecule has a NOO group, that makes that the two isomers have a completely different structure, with the atoms arranged in a completely different order. <span>This kind of isomers fits in the definition of structural isomers, so the answer is structural isomers.</span>
It means that 22.5×10^5 J of heat is required to change 1 kg of water into steam.
Latent heat of vaporization is amount of energy required to change 1 gram (in this example 1 kilogram) of material from the liquid to the gaseous state at its boiling point.
Boiling point of the water is 100°C.
Joule (J) is the standard unit for energy (in this example heat).
Evaporization is phase change process in which the water changes from a liquid to a gas (water vapor). Fore example, solar radiation can be the source of energy for evaporation.

Answer:
count how many electrons it 'owns'
The rest of the wood was burned into gases of equivalent weight.
<u>Explanation</u>:
The rest of the wood was burned into gases of equivalent weight.
- When wood is burnt in the open air, with the help of oxygen and heat, it is transformed into carbon dioxide, water vapor, and ashes.
- Ignition and combustion of wood mainly depend on pyrolysis which is also known as thermal combustion.
- The loss in weight of the ashes is due to the fact that gases and water vapor are also formed due to the combustion of wood.
