Answer:
( A ) Increases
Explanation:
More room, basically means more creatures. Like in a bedroom, you can only fit amount of people if its small the ocean is like that with depth.
Hopefully this makes sense???
12000 ml would be d to my calculations but then u can 12
Speed = distance/time
=> speed = 817/19 m/sec = 43 m/sec
hope it helps!
Answer:
C 108
Explanation:
1 It was found that 4n atoms of metal x
weigh 501.6 g. The relative atomic mass
of X is 209. If n atoms of another metal,
Y, weigh 65.00 g, what is the relative
atomic mass of metal Y?
A 27 B 52 C 108 D 137
if 4n atoms of x weigh 501.6 gm, the n atoms weigh 501.6/4 = 125.4 gms
since the atomic mass is 209, then 6.022 X10^23 atom weigh 209
the ratio of 125.4 to 209 is
125.4/Y =0.6
therefor n is the number of atom in 0.6 moles
if metal Y has the same, number of atoms "n" and weighs 65 gm
then then the relative atomic mass is
65/0.6 =108
so the answer is
C 108
Atomic mass is the number of protons and neutrons in an element while an atomic number is the number of protons in the element.
