Answer:
Option A. Dense water floats.
Explanation:
Ocean circulation act as conveyor belt which transport warm water from the tropics towards poles from where cold water sinks to the deep ocean. It is also known as the thermohaline circulation because it is driven by salinity and temperature.
However, change in climate causing these ocean's thermohaline current to slow down because influx of cold and melting fresh water from the polar region is disrupting these circulation as influx of fresh water making the water less saline and less dense and hence it become harder to sink to deep ocean.
The largest mass silver chloride is precipitated when excess silver ions are added to 30.0cm3 of 0.30M iron(III) chloride solution.
<h3>What is a precipitation reaction?</h3>
A precipitation reaction is a reaction in which an insoluble substance is obtained when two solutions are mixed together as a result of one of the products of the reaction being insoluble in water.
Silver chloride is an insoluble salt that will precipitate when a single silver salt is added to a soluble chloride salt.
In the above, the largest mass silver chloride is precipitated when excess silver ions are added to 30.0cm3 of 0.30M iron(III) chloride solution since iron (iii) chloride is a weak electrolyte.

"<span>Let's start with the basics: you have
probably heard that your body is 90% (or 85% or 95%) water. In actual
fact, water is (probably--unless you are obese) the majority of your
body weight--but nowhere near 90%. The best estimate I have seen is 57%
(Body water). So that puts hydrogen and oxygen in the top four.
As
I mentioned, extremely obese people can be less than 50% water. Fat
(triglycerides) is composed of carbon, hydrogen, and oxygen. The
majority of the mass of a triglyceride is carbon--chemically it is
closely related to biodiesel. So that puts carbon in the top four.
Finally,
amino acids which make up proteins (which make up muscle) require
nitrogen. That makes the top four.: Oxygen, Carbon, Hydrogen, and
Nitrogen.
But wait! What about bones? Aren't they calcium and phosphorous? Bones are really heavy.
It
turns out that calcium and phosphorous are indeed the next two most
abundant (by mass) elements in the body, but where nitrogen is about 3%
of your body mass, calcium and phosphorous are 1.5% and 1.2%
respectively.

Answer:
D or the 4th one
Explanation:
mass is literally the measure of matter in an object which is essentially the weight or how much stuff there is.
The hydrogen ions are moved into the thykaloid
