Answer:
A
Explanation:
Isomerism is a phenomena whereby two or more organic compounds have the same molecular formula but different structural arrangements.
This means the organic compounds may belong to different organic family but the main idea is that they have different structural and spatial arrangements but the same molecular formula. This means they have the same number of each atoms
Answer:
- <u><em>1.7 × 10³ kg of ore.</em></u>
Explanation:
Call X the amount of aluminum ore mined to produce 1.0 × 10³ kg the aluminum metal.
Then, taking into account the yield of the reaction (82 % = 0.82) and the percent of aluminun in the ore (71% = 0.71), you can write the following equation:
- X × 71% × 82% = 1.0 × 10³ kg
↑ ↑ ↑ ↑
(mass of ore) (% of Al in the ore) (yield) ( Al metal to obtain)
You must just simplify, solve and compute:
- X = 1,000 / (0.71 × 0.82) = 1,000 / 0.5822 = 1,717.6 Kg
Round to two significant figures; 1,700 kg = 1.7 × 10³ kg of ore ← answer.
Density is equal to mass divided by volume so the densest object will be the object that has the largest mass in the smallest area.
In this case object A is the densest with a density of 10g/cm^3.
I hope this helps. Let me know if anything is unclear.
C. When temperature increases gas molecules increase in kinetic which they move around
When an object is placed on the opposite end of a lever and the near end is held in place without being allowed to move upwards, the lever has potential energy.
