Answer:
c) evaporating
d) has no salt in it
Explanation:
no problem anytime. just try to understand the concept and it will definitely help if you read the question more than once.
the change of state that is happening the surface of the sea water is evaporating. This is because it allows from liquid to vapour/ gas based on the diagram
the water in the test tube is different from sea water because it is pure meaning no salt. It's evident based on figure 2 because sea water is full of solutions and mixtures.
Answer:
101
Explanation:
Provided that
And,
Now we expect the same
{S} (0.1mM)
This determines that generates a higher rate of product formation as compared to the
So we can easily calculate the for either of or as we know that Tube 1 is and tube 2 is
As we know that
As the rates do not include any kind of units so we do not consider the units for
Now the calculation is
= 100.5
≈ 101
Answer:
The best answer is "E"
NaCl leaves the ascending limb of the loop of Henle through active transport.
Explanation:
The loop of Henle is a U-shaped portion of the tubule that conducts urine within each nephron. It's principal function is the recovery of water and sodium chloride from the urine.
The ascending limb is impermeable to water. NaCl is pumped from the tubule into the interstitium in the ascending limb by active transport. This active transport enables the kidney to establish an osmotic gradient which enables the permeability of water and urea thereby allowing the kidneys to concentrate the urine.
Given :
15 g of potassium react with water .
To Find :
How much potassium hydroxide and hydrogen gas will be produced by the chemical reaction .
Solution :
Balanced chemical equation is given by :
Number of moles of potassium are :
From the chemical equation we can see that 1 mole of potassium produce 2 moles of KOH and 1 mole .
So , 0.38 mole of potassium will produce :
Mass of KOH produced , .
Mass of produced , .
Therefore , mass of potassium hydroxide and hydrogen gas produced is 42.56 g and 0.76 g respectively .
