Wood, when dry, stores chemical energy. This chemical energy is released as the wood burns, and it is converted into heat, or thermal energy. This also produces light energy. As a result of burning, the wood turns into an entirely new substance - ashes. Wood, a form of fuel with lots of potential energy stored in its covalent bonds, will react with molecules of oxygen in the air in a dramatic chemical reaction we call fire. The complex molecules in the wood have 'high energy' covalent bonds, as do the molecules of oxygen.
I hope this helped:))
To determine if your hypothesis was correct for future reference
Answer:
Explanation:
Actually it was the experimental results of other scientists. The main stems of the theory was the indivisibility of small spheres (his image) that represented the elements he knew which reacted with other elements.
They seemed to give the same ratios in reactions (definite proportions) and multiple whole number ratios. Look up Lavoisier.
Answer:
Starch
Explanation:
Any member of a class of enzymes that catalyze the hydrolysis (splitting of a compound by addition of a water molecule) of starch into smaller carbohydrate molecules such as maltose (a molecule composed of two glucose molecules).
Protists are eukaryotic organisms that do not plant, animal, or fungus.
The kingdom Protista includes an organism that can survive by photosynthesis in the presence of light or by consuming organic material in dark conditions.
<h3>What are protists?</h3>
Protists are eukaryotic organisms.
The nutrition present in them is mixotrophic.
Some organisms make food through photosynthesis and some are parasites and some consume organic material.
Thus, the correct option is protists, they can survive by photosynthesis in the presence of light or by consuming organic material in dark conditions.
