Answer:
Smallest of the three = 40
Step-by-step explanation:
Consecutive means: x+x+1+x+2 = 123 set X as the smallest number.
x+x+x+1+2=123
3x+3=123
3x= 120
x=40
Answer:
Empirical formula= COOH
Step-by-step explanation:
Molecular mass of the elements
Carbon= 12
Oxygen= 16
Hydrogen= 1
We divide the elements each with their molecular formula
Carbon= 2.4/12
Carbon= 0.2
Oxygen= 6.4/16
Oxygen= 0.4
Hydrogen= 0.2/1
Hydrogen= 0.2
Now we divide with the smallest result which is 0.2
Carbon= 0.2/0.2
Carbon = 1
Oxygen= 0.4/0.2
Oxygen= 2
Hydrogen= 0.2/0.2
Hydrogen= 1
So we have
Carbon 1, oxygen 2, hydrogen 1
Empirical formula= COOH
The answer is B because the quantity tends to stay the same as the sample goes up
Answer:
10
Step-by-step explanation:
6 is the width not the length
You could just subtract it or you could make it into a plus negative
