Answer: Carbohydrates (carbo- = “carbon”; hydrate = “water”) contain the elements carbon, hydrogen, and oxygen, and only those elements with a few exceptions. The ratio of carbon to hydrogen to oxygen in carbohydrate molecules is 1:2:1.

<u>Residual soil and transported soil differ by as follows:</u>
Residual soil stays over its parent rock and transported soil forms from particles from another place.
<u>Explanation:</u>
Soil forms from weathering of rock. When a rocks get weathered it creates small paiticles. That forms different kind of soil. Soil varies in texture, structure, colour, composition and in pH level. Each and every soil type produced from parent rock. Depending upon the character of parent rock soil type is determined like basalt the igneous rock forms black soil.
Residual soil stays over parent rock it does not get off by the activities of natural agents like air, water, wind and glacier. Transported soil comes from hilly area to flat topped ground by transportation through some transporting agents of nature. It is immature soil.
1) The time depends on what the lab wanted you to do. It will tell you in the procedure when you are supposed to considered a reaction to be complete and you just measure the time for that to happen.
2) Most text books say that increasing the concentration of one or more reactants will increase the rate of the reaction. To prove this with your data you need to show that when you increased the concentration of one of the reactants, the reaction rate did increase. The results of this experiment are not enough to make a general statement since the experiment was not on a large enough scale to diffidently prove anything. (you could have been testing the one exception or had a error in one of your trials)
I hope this helps. Let me know in the comments if anything is unclear.
(The concentration of one or more of the reactants will increase the rate of the reaction. This is explained through the fact that all reactions require collisions that have certain orientations and a minimum energy level. By increasing the concentration of one or more reactants, you increase the number of collisions which increases the rate since requires collisions in order to occur.) <span />
