Gravity plays an important role in how we build our houses and structures. If gravity was much weaker on Earth, we would be able to use structures that are not as resistant. Buildings would not have to carry as much weight, which would mean that weaker materials would be able to be used.
On the other hand, much stronger gravity would mean that buildings would have to endure a lot more pressure. Moreover, everything inside the building (furniture, people, etc.) would be heavier, which would require stronger structures.
Explanation:
solution is neutral because it added water and water is neutral solution
- Making Materials
- Moving Materials
- Removing Waste
Answer:
You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled
Moving Materials include aluminum foil tape, shipping tape, box tape and duct tape. Moving labels take the guesswork out of the moving process.

How is salicylic acid obtained?
Answer:
13.39 mol ≅ 13.4 mol.
Explanation:
Using cross multiplication:
1.0 mole of Cl₂ occupies → 22.4 L.
??? mole of Cl₂ occupies → 300.0 L.
∴ The no. of moles of Cl₂ are in 300 liters = (1.0 mol)(300.0 L)/(22.4 L) = 13.39 mol ≅ 13.4 mol.
