I am pretty sure the answer is A
Answer:
A. 15859.2 L or 15900 L
B. 0.629 mol
Explanation:
At STP, one mole is equal to approximately 22.4 L
L or mL is volume, so you are attempting to solve for L or mL.
A.
708 mol x (22.4 L/1 mol) = 15859.2 L (w/ significant figures included - 15900 L)
B.
(14.1 L) x (1 mole/ 22.4 L) = 0.629 mol.
Answer:
Fish, marine mammals and seabirds are being injured and killed by plastic corruption /pollution, and it is believed that 700 species could go deceased because of it. ... Losses are generally influenced by the ingestion of plastics, starvation, suffocation, virus, drowning and entrapment.
You can thank me and google
x 0,025
HCl+KOH--> KCl + H2O
1 1
c=1M
V=25ml=0,025l ( you need the volume to be in l)
c = n/V
n=c*V
n=1*0,025=0,025 m KOH
x=0,025m
c=1 M
V=n/c
V=0,025/1=0,025l=25ml HCl
Answer: (c) CHCl3
Explanation:
From the rule : a polar solvent will dissolve a polar compound and a non polar solvent will also dissolves a non polar compound.
(a) CH4 is non- polar and water is a polar solvent. Therefore CH4 is not soluble in water
(b) CCl4 is non polar and water is a polar solvent. Therefore CCl4 is not soluble in wtaer
(c) CHCl3 is polar molecule and water is also a polar solvent.
Therefore CHCl3 is expected to be most soluble in water
