We collect gas using special apparatus because most gasses cannot be seen, hence we may find it difficult to tell if our test tube is filled, and the best method to collect gas is through water.
One of the apparatus we use in collecting gas is pneumatic trough. A pneumatic trough is a piece of laboratory apparatus used for collecting gases, such as hydrogen, oxygen and nitrogen.
<em>Assumptions we make when using the gas collection apparatus</em>
The assumption we make is on the basis of the ideal gas assumption which are:
- The gas consists of a large number of molecules, which are in random motion and obey Newton's laws of motion;
- The volume of the molecules is negligibly small compared to the volume occupied by the gas; and
- No forces act on the molecules except during elastic collisions of negligible duration.

Answer:
"Wood is technically a renewable source of energy, since it is a form of biomass. All biomass is traditionally considered a renewable source of energy because it is part of the natural carbon cycle on Earth." I found this from https://www.quora.com/
Explanation:
Answer:
To have the electronic configuration equal to 1s²2s²2p⁶3s²3p⁶4s²3d⁷, the chemical element must have an electrical charge equal to 27, that is, it must have 27 electrons, such as Cobalt (Co), for example.
Explanation:
The electronic configuration shown in the question above is known as the Linus Pauling distribution and represents the energy sub-levels that an electrically charged atom can have in relation to the amount of electrons it has.
The layers sub-levels are presented in the following order 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹º 4p⁶ 5s² 4d¹º 5p⁶ 6s² 4f14 5d¹º 6p⁶ 7s² 5f14 6d¹º 7p⁶. Where the small numbers represent the number of electrons in each sub-level and the large numbers represent the layers of electronic distribution.
Accordingly, we can see that an atom that has the configuration 1s²2s²2p⁶3s²3p⁶4s²3d⁷ has 27 electrons, like Cobalt.
