For the answer to the question above, the best lubricant has around 17-35 saturated hydrocarbons. Lubricants can either be liquid (oils) or solid (grease). Oils typically have 15-20 carbon atom chains, while grease has 20-35 carbon atoms chains. This means that both lubricant types fall under the range 17-37.
I’m stuck on that question
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:
Mercury is bad at sharing electrons.
Explanation:
Most metal atoms readily share valence electrons with other atoms. The electrons in a mercury atom are bound more tightly than usual to the nucleus.
