A. As pressure on the gas increases, the volume and temperature will both decrease
If the grade of the ore is 37.3% nickel, then the unknown quantity to get 10 grams of nickel is 0.373 x = 10 grams or x = 10/0.373=26.8 grams or 0.0268 kg needed to dig up to recover the 10 grams of nickel. At this grade of ore, 1 kilogram would yield 373 grams of nickel.
Answer:
gravity
Explanation:
the force is gravity that pulls the ball downward
Answer:
Solids.
Explanation: Most elements are solids, only 11 are gases and 2 are liquids.
Answer:
A) 1
B) 2.5
C) 3.32
Explanation:
The possibility of n=1 is not achievable in 20 minutes and 30 minutes as calculated n=1 for 10 minutes. The same conversion cannot be achieved for the rest of the time which is impossible as 75% conversion and it cannot be achieved at 10 min and 20 min at the same time
A) what is the order of the reaction if it takes 10 minutes to reach 75% conversion
= n ( order ) = 1
B) what is the order of reaction if it takes 20 minutes to reach 75% conversion
= n ( order ) ≈ 2.5
C) what is the order of reaction if it takes 30 minutes to reach 75% conversion
= n ( order ) ≈ 3.32
