Explanation:
In this problem, we are given a conversion factor.
So, since we know this, we can simply multiply 25 by 6.5 to see what the distance will be.
25 * 6.5 = 162.5
So, the distance traveled for 25 seconds is 162.5 miles.
On a small time scale, glass is in a solid state. When you look at a window, it appears solid.
However, it has been observed that over a very long period, glass starts to act like a liquid.
It can thus be characterized by two different states depending on the time scale considered.<span />
Answer:
B
Explanation:
Isotopy is a phenomenon in which there exists two or more kind of atoms of the same element. These atoms have the same number of protons but different mass numbers. That is, they have the same atomic number but differ only by the number of neutrons in the nucleus of the atom. Now, let us apply this information to the options individually:
A. Is wrong, they are not the same element
B. Is correct. they both belong to the same element hydrogen. Infact, they are named protium and deuterium respectively
C is wrong they are not same element
D is wrong They are not elements at all
E. Is wrong, one is an element, the other is a molecule
Answer:
C: Plants mostly need air, water and sunlight to grow

Hello!
In this case, since the dilution processes are characterized by the decrease of the original stock solution by holding the moles constant and therefore modify the volume, for the described dilution we can write:
Whereas we are asked to compute the volume of the original solution; thus, we can solve for it as shown below:
Best regards!
