What is the ratio of hydrogen atoms (H) to oxygen atoms (O) in 2 L of water? Enter the simplest whole number ratio in order of h
1 answer:
Answer : The ratio of hydrogen and oxygen in water is, (2:1)
Explanation :
As we know that the chemical formula of water is, .
In , there are 2 atoms of hydrogen and 1 atom of oxygen.
As we are given that the volume of water is, 2 L. So, there is no matter what is the volume of water that means there is no role of volume of water.
The ratio of hydrogen and oxygen in water is, (2:1)
Thus, in 2 L volume of water, the ratio of hydrogen and oxygen in water is also same that is, (2:1)

Answer:
(d) 3,7-dimethyl-4-nonyne.
Explanation:
Hello,
In this case, considering the attached picture on which you can see that the main chain has nine carbon atoms, one tripe bond at the fourth carbon and two methyl radicals at the third and seventh carbons respectively, by following the IUPAC rules, the name would be: (d) 3,7-dimethyl-4-nonyne since the chain must start at the side closest to the first triple bond due to its priority and subsequently considering the present radicals.
Best regards.
<u>Answer:</u> The volume of given amount of ethanol at this temperature is 159.44 mL
<u>Explanation:</u>
Specific gravity is given by the formula:
We are given:
Density of water = 0.997 g/mL
Specific gravity of ethanol = 0.787
Putting values in above equation, we get:
Density is defined as the ratio of mass and volume of a substance.
......(1)
Given values:
Mass of ethanol = 125 g
Density of ethanol = 0.784 g/mL
Putting values in equation 1, we get:
Hence, the volume of given amount of ethanol at this temperature is 159.44 mL
