When wood burns what 3 types of chemical energy is it?

so the step is it

Wood - Dry wood stores chemical energy. This chemical energy is released as the wood burns, and it is converted into heat, which is also called thermal energy, and light energy. As a result of burning, the wood turns into an entirely new substance – ashes. Explosives - When an explosive goes off, chemical energy that was stored in the explosive is changed and transferred into sound energy, kinetic energy, and thermal energy. These are observable in the sound, motion, and heat that are created. Food - The chemical energy in food is released while the food is being digested and the molecules of food are broken down into smaller pieces. As the bonds between the atoms of the food break or loosen, new substances are created as a result of the chemical reactions taking place. Bleach and ammonia - When these two substances are mixed, an entirely new substance – a toxic chemical called chloramines vapor - is produced.Heating packs - These handy packages that are used to warm up cold hands or sore muscles have chemicals inside of them. When you crack the pack to use it, chemicals are activated. These chemicals mix together, and the chemical energy that they release creates the heat that warms up the pack.Vehicle air bags - The bags are activated by a chemical reaction inside the bag. A sensor turns on an electrical circuit, and then sodium azide is ignited. The reaction that occurs generates nitrogen gas, which fills the bag at an extremely rapid rate. Baking soda and vinegar - When these two substances are mixed in a container, carbon dioxide gas is produced. As this gas grows in volume, it puts pressure on whatever container it is in, and will erupt out of an opening in the container, creating a volcano effect.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
