Answer:
Hey there! :)
Explanation:
Answers;
165lbs = 74842.74
12.01cm = 0.1201
………………….……………………………………
(Answers will be explained)
~So first let’s do question ‘A’
A. 165 lbs=?? g
~We have to use the formula.
Grams=Pounds X 453.59237
(Note: 1 lb = 453.59237)
~With that being said, we can see that the pounds in 165. So we have to multiply using the formula.
~165 X 453.59237
⇒ Equals to 74842.74
So question ‘A’ is 74842.74
==================================================
~Okay now let’s do question ‘B’
B. 12.01 = ?? m
~Let’s first see what the formula is.
~Meters = Centimeter * 0.01
Or...
~Meter = Centimeter / 100
(Note: 1 m = 100 cm)
~Okay now let’s use the formula to find the answer.
(We use the formula)
12.01 / 100
⇒ Equals to 0.1201
~Hope this helps!~
^^Good luck!^^
~Have a nice day! :P

Answer:
Direct relationship.
Explanation:
There is direct relationship between enzyme activity and temperature of reaction. Direct relationship means if one factor is increases the other factor is also increase and vice versa. In chemical reactions, the rate of an enzyme action increases as the temperature of the chemical reaction also increases. we see a flattening of the curve for the 75 degree reaction after 3 minutes because the enzyme action is not working at that temperature or in other words, this temperature is not suitable for the enzyme activity.
Answer:
Ca^2+
Explanation:
As we know, more energy is required to remove an electron from a positively charged ion than is required to remove an electron from a neutral atom. Hence, the second ionization energy of calcium is greater than its first ionization energy.
However, the third and fourth ionization energies of calcium are much higher than the second ionization energy because they involve removal of electrons from an inner filed shell. This process requires a lot of energy and is often not feasible.
Hence, the most common ion of calcium must be Ca^2+ where only two electrons are removed from calcium.
