Answer:
The molarity of the solution is 0,12 M.
Explanation:
We calculate the molarity, which is a concentration measure that indicates the moles of solute (in this case KOH) in 1000ml of solution (1 liter):
0,25 L solution----- 0,030 moles of KOH
1 L solution----x= (1 L solution x 0,030 moles of KOH)/0,25 L solution
x= 0,12 moles of KOH ---> <em>The solution is 0,12 M</em>
Explanation:
The photic zone, euphotic zone, epipelagic zone, or sunlit zone is the uppermost layer of a body of water that receives sunlight, allowing phytoplankton to perform photosynthesis. It undergoes a series of physical, chemical, and biological processes that supply nutrients into the upper water column. The photic zone is home to the majority of aquatic life due to its location.
Photosynthesis in photic zone Edit
In the photic zone, the photosynthesis rate exceeds the respiration rate. This is due to the abundant solar energy which is used as an energy source for photosynthesis by primary producers such as phytoplankton. These phytoplankton grow extremely quickly because of sunlight's heavy influence, enabling it to be produced at a fast rate. In fact, ninety five percent of photosynthesis in the ocean occurs in the photic zone. Therefore, if we go deeper, beyond the photic zone, such as into the compensation point, there is little to no phytoplankton, because of insufficient sunlight.[1] The zone which extends from the base of the euphotic zone to about 200 meters is sometimes called the dysphotic zone.[2]
follow me ok nice study ☺️☺️☺️
This is a physical change.
Answer:
0.67 mole/litre
Explanation:
the molarity equall no. of moles ÷ volume of sol.
Answer:
The best option is "Heat is transferred by the interaction of moving particles."
Explanation:
The Kinetic Molecular Theory of Heat states that molecules in a fluid increase their speed as temperature increases.
Kinetic theory of heat is a theory that the temperature of a body is determined by the average kinetic energy of its particles and that an inflow of heat increases this energy.
Heat and temperature are related to each other, but are different concepts.
1. Heat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance.
2. Temperature does not depend on the size or type of object.
Also heat can be transferred but temperature can't be transferred.
