Chemical reactions are the molecular and ionic rearrangement of the reactants to form products. The order of the reactions is combustion, photosynthesis and respiration.
<h3>What are the types of reactions?</h3>
A <u>combustion reaction</u> is a chemical reaction in which the reactant reacts in the presence of oxygen to yield the products and some amount of heat and energy. Burning of the fossil fuels in the presence of atmospheric oxygen is the combustion reaction.
<u>Photosynthesis </u>is a biochemical reaction that occurs in the presence of solar energy that converts carbon dioxide and water to produce sugars and oxygen in plant cells. Tomato plantation is an example of photosynthesis.
<u>Respiration </u>is a process by which the organism utilizes food and oxygen as energy sources required by the body to function and perform activities. Eggs are the source of the energy and are a respiration reaction.
Therefore, the order of the reactions is combustion, photosynthesis and respiration.

Answer:
The water bends due to the static electricity on the balloon.
Explanation:
The static electricity you built up by rubbing it against the balloon attracts the stream of water, bending it towards the comb or balloon like magic!
Negatively charged particles called electrons jump the wool to the balloon as they rub together, the comb now has extra electrons and is negatively charged. The water features both positive and negatively charged particles and is neutral. Positive and negative charges are attracted to each other so when you move the negatively charged balloon towards the stream, it attracts the water's positively charged particles and the stream bends!
Answer:
Option (d) chlorine has a greater ionization energy than sodium
Explanation:
Ionization energy is the energy required to remove an electron from a gaseous atom or ion. Sodium has just 1 electron in it's outmost shell and chlorine has 7.
Sodium needs 7 electrons to complete it's octet configuration and chlorine needs just 1.
Sodium can not attract 7 electrons to complete it's octet configuration instead it will easily lose the 1 electron in it's outmost shell to form cation. On the other hand, it will be difficult for chlorine to lose any of it's outmost electrons. This makes chlorine to have higher ionization energy than sodium.
