I think this answer is D or C
Answer:
Explanation:
Well you didn’t send a picture of the question but h2O is water so. If the questions answer has a option of water then pick that one
Hello!
We use the amount in grams (mass ratio) based on the composition of the elements, see: (in 100 g solution)
C: 83.7% = 83,7 g
H: 16.3% = 16.3 g
Let us use the above mentioned data (in g) and values will be converted to amount of substance (number of moles) by dividing by molecular mass (g / mol) each of the values, lets see:


We note that the values found above are not integers, so let's divide these values by the smallest of them, so that the proportion is not changed, let's see:


Note: So the ratio in the smallest whole numbers of carbon to hydrogen is 3:7, t<span>hus, the minimum or empirical formula found for the compound will be:

I hope this helps. =)
The answer is Xylem. The plant structure that helps transport water and nutrients from the roots to the leaves and other parts of the plant is Xylem. In vascular plants, plants that have TUBELIKE STRUCTURES that carry water, nutrients, and other substances throughout the plant have xylem (<span>vascular tissue that carries water upward from the roots to every part of a plant) </span>and phloem (vascular tissue tubelike vessels that transport sugar made in photosynthesis from leaves to plant).
My educated guess should be the 3rd one
