Answer:
B: 2800 hydrogen atoms
C: 6760 hydrogen atoms
D: y=amount of oxygen atoms*2
Step-by-step explanation:
B: We know the formula for water is H2O. SO that means that there is 2 hydrogen atoms and 1 oxygen atom. So there is 2 times the amount of hydrogen atoms so we can do 1400*2=2800, So there is 2800 hydrogen atoms in the water.
C: Same thing as B. 3380*2=6760
D: y=amount of oxygen atoms*2. Because there is one oxygen atom and two hydrogen atoms so 1*2=2.
Answer:
A, B and C
Step-by-step explanation:
example of B
-3×2/3 =-2
-2+2 =0
Y=1 and >0
A and C are also right
Edit: I changed my originally wrong answer, the second poster was right
The answer is 0.02 because the 2 is in the hundredths place
