Answer: Because Alkalis are bases that can dissolve in water, which can also neutralize acid.
The sample of smoke described above can be described as a heterogeneous mixture. This type of mixture do not have uniform properties and composition. So, getting a certain small sample would not represent the whole mixture since it does not have uniform composition.
Just look at the number in front also called coefficient (you have to balance the equations first, but all the questions here are balanced, so no worries). for q1.
in the balanced equation, the number in front of aluminum oxide is 2 (2 - this number Al2O3) and for aluminium is 4 as in (4 Al). so the ratio is 2:4. simplified it is 1:2. or write it out fully
2 Al2O3: 4 Al
ignore everything after the number.
2:4
same as 1:2
Aluminium oxide to oxygen
2 Al2O3: 3 O2
2:3
aluminum to oxygen
4 Al: 3 O2
4:3
question 2
Mercury oxide to Mercury
2 HgO : 2 Hg
2:2
same as 1:1
Mercury oxide to oxygen
2 HgO : O2
since oxygen in this case does not have a number written in front of it, the default is 1.
2: 1.
you should be able to do the rest
Answer:
carbon dioxide

The Number of moles required for MTBE is 2 as per molarity based chemistry theories.
- A flammable liquid with a distinct, unpleasant smell is called methyl tert-butyl ether (MTBE).
- Since the 1980s, it has been added to unleaded gasoline as a fuel additive to promote more effective burning.
- It is created by mixing chemicals like isobutylene and methanol. Gallstones can be removed with MTBE as well.
- In this type of treatment, surgically inserted special tubes are used to deliver MTBE directly to the gall bladders of the patients.
- Methyl tert-butyl ether is a colorless liquid with a distinct anesthetic-like smell. Vapors are narcotic and heavier than air. 131 °F boiling point. 18 °F is the flash point.
- It is miscible in water and less dense than water. Boosts the octane of gasoline.
- Therefore it has 2 moles of oxygen.
