The answer is b (the second choice)
Answer:
false
Explanation:
the answer is false because there is minerals in our water, ect.
Answer:
D
Explanation:
Acceleration = velocity/time
A = 2*20
A = 0.10 m/s²
Explanation;
Writing scientific notation :
- Move the decimal to the left side until single digit of number remains before the decimal.
- Then we will count the number of times we moved the decimal. Write this number as the exponential power of number '10'.
- For Example:

Radius of the sun = 696,000.0 kilometer

Radius of the sun can also be written as =
Size of bacterial cell =
millimeter

Size of bacterial cell can also be written as = 
The second reaction with the volume of 5L will occur faster as compared to the first reaction of volume 10L.
Volume is inversely proportional to the rate of reaction.
As volume increases rate of reaction decreases and as volume decreases rate of reaction increases.
Let's consider a reaction A → B.
r is rate of reaction and K is rate constant, A is the concentration of reaction.
r = k(A)
r is directly proportional to the A.
But the concentration of A is in Moles/liters (i.e. moles per unit volume)
r is inversely proportional to the volume of vessel or chamber.
Hence as volume increases rate of reaction decreases.
