The type of element will change and the mass of the atom will change; A and B
Answer:
15L will be the final volume
STEPS:
.50 + .25 = .75
.25/5 ÷ .75/x
(.75*5=3.25)
.25x = 3.25
x=15
quizlet
It depends if you are talking about the ones that go up or down
or left and right
the ones that go up and down are called groups
the onesthat go left and right are periods
All organic molecules must have carbon and hydrogen so it would be choice A
Answer:
