The density does not change because it is still the same liquid as before
Answer:
No because water needs to have no salt
Explanation:
They have different ratios of elements. Water is H20 and Hydrogen Peroxide is H202. The extra oxygen atom in hydrogen peroxide causes it to be structured and react differently.
<u>Answer:</u> The percent composition of hydrogen in the sample is 15.22 %
<u>Explanation:</u>
We are given:
Mass of hydrogen = 7 grams
Mass of nitrogen = 32 grams
Mass of carbon = 7 grams
Total mass of the sample = 7 + 32 + 7 = 46 grams
To calculate the percentage composition of hydrogen in sample, we use the equation:

Mass of sample = 46 g
Mass of hydrogen = 7 g
Putting values in above equation, we get:

Hence, the percent composition of hydrogen in the sample is 15.22 %
