Answer:
the same chemistry student has a weight of 155lbs what is the student weight in grams? (16 oz= 1 lb, 1 oz= 28.34g)
Explanation:1 lb = 16oz, so multiply your pounds by 16 to get you ounces of the student, then multiply by 28.34 to get grams
155 X 16 X 28.34 = 70283.2
Answer:
a, b
Explanation:
Electrolytes dissociate to make ions, because of it they conduct electricity.
Answer:
The rate of flow of nitrogen into the reactor is 2,470.588 kg/h.
Explanation:
Mole percentage of nitrogen gas = 25 mole%
Mole percentage of hydrogen gas = 75 mole%
Average molecular weight of the mixture:
Rate of flow of the stream = 3000 kg/h
Mass of stream in 1 hour = 3000 kg = 3,000,000 g
Moles of stream :
Moles of nitrogen gas in 352,941.17 moles of stream be x
x = 88,235.294 mol
Mass of 8,823,529.4 mole of nitrogen gas:
The rate of flow of nitrogen into the reactor is 2,470.588 kg/h.
The answer is:
carboxylate
and protonated amines
The explanation:
when
The Carboxylic acids are polar . and the functional group carboxyl is formed from the hydroxyl and carbonyl group.
and about protonated amines:
-alkyl groups improve the basicity, aryl groups diminish it.
-Primary amides have an aromatic group or alkyl attached to an amino-carbonyl function.
- Primary amines are basic functions which could be protonated to the ammonium ion
Atomic weight of the element = atomic weight of isotope 1 * abundance of isotope 1 + atomic weight of isotope 2 * abundance of isotope 2
Atomic weight of the element = 120.9038 amu * 57.25% + 122.8831 amu * (1 - 57.25%)
Atomic weight of the element = 69.2174255 + 52.53252525 = 121.74995075
=> ~ 121.7500 <--------- answer
