Answer:
D. water currents melting the glaciers in Antarctica
Explanation:
The hydrosphere contains all the water on earth ranging from underground water, water in the air and water running on the surface of the earth. This water exist as liquid or ice. In liquid form, it includes water in the sea, ocean, river, underground water (wells, aquifers) and water vapor. In ice form, it includes: glaciers, ice caps and icebergs. The frozen part of the hydrosphere is known as the cryosphere.
There are interactions between the hydrosphere and cryosphere such as water currents melting the glaciers in Antarctica, melting of snows and ice.
Answer: D. To decrease the total moles of gas in the system
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.
This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
when the pressure is increased, , the volume will decrease according to Boyle's Law. Now, according to the Le-Chatelier's principle, the equilibrium will shift in the direction where decrease in pressure is taking place.
As the pressure is directly proportional to the number of moles of gas molecules. So, the equilibrium will shift in a direction where the total moles of gas are decreasing.
Thus the correct answer is to decrease the total moles of gas in the system.
Answer:
C6H12O6
Explanation:
Just use the table method like I did and compared the molecular mass with the mass of the empirical formula.
Answer:
The term Decimal is coined from the word Decimus. Decimus is a Latin word which means ‘tenth’.
The Decimal system is a system of numbering that is based on multiples of tens. It is flexible and easy to convert from one metric to another.
The preference of the term over the Metric System is because the word Metric is related more to the measurement of lengths if we looked at the origin of the word which is French.

The dye molecules move in a directed way from high to low concentration
Explanation:
The statement that best describes the motion of dye molecule in water is directed from a region of high to low concentration. The motion of the particles of the dye in water is described as diffusion:
- diffusion is the movement of molecules of a substance from one position to another.
- diffusion occurs from a region of high concentration to that of a low concentration.
- the dye in the water solution causes an increase in concentration of an area where it is dropped.
- this causes the particles to spread outward in the solution.
- a concentration gradient is set up between the two parts of the solution.
- this gradient facilitates the movement of the dye particles.
