Answer: The concentartion of solution will be 0.224 M
Explanation:
Molarity : It is defined as the number of moles of solute present per liter of the solution.
Formula used :
where,
n= moles of solute =
= volume of solution in ml = 275 ml
Now put all the given values in the formula of molarity, we get
Therefore, the concentration of solution will be 0.224 M
Answer:
Here is the full sentence: Enzymes affect the reaction in living cells by changing the SPEED OF THE REACTION.
Explanation:
The options attached to the question are given below:
A. Products of the reaction
B. Speed of the reaction
C. Temperature of the reaction
D. pH of the reaction
Enzymes are chemical substances, that affect the rate of biochemical reactions by speeding up the rates at which the reactions occur. Enzymes are found in all living cells and they are formed mostly from proteins. Enzymes speed up the rate of biochemical reaction by lowering the activation energy of the reaction. Each enzymes catalyses only specific reactions and work best under specific conditions.
Answer:
In physics, a region in which each point is affected by a force. The strength of a field, or the forces in a particular region, can be represented by field lines; the closer the lines, the stronger the forces in that part of the field. See also electromagnetic field.
