Question 1:

The right answer is A

Chemistry is a science of experimental nature that studies the composition of matter and its transformations.

Chemistry is thus interested in the elements that constitute matter (atoms, ions, etc.), in their properties and in the chemical bonds that can be created between them.

Question 2:

The right answer is A

Sodium chloride is an ionic chemical compound of the formula NaCl. It is more commonly called table salt or cooking salt, or simply salt in everyday language.

It is clear that it exists in the form of solid salts.

during his training, there was a physical change of sodium (metal) and chlorine (gas) into a salt.

Question 3:

This question is a little bit tricky

If we assume that the question is aimed at finding the total number of oxygen in all three molecules together, the answer is 18.

A glucose molecule is made up of 6 atoms of oxygens if we have three glucose molecules (assuming that they are bound), we multiply by 3 and this gives us 18 oxygen atoms.

Which statement is false about fungi?
alekssr [168]

Answer:

C) Most fungi get their nutrients by ingesting small pieces of other living organisms.

Explanation:

Most fungi are saprotroph, it is, they obtain  nutrients by decomposing  non-living organic matter -i.e.  dead plant or animal matter-  and absorbing soluble organic compounds; carbohydrates are the preferred carbon source.

A smaller percentage of fungal species are parasites, and obtain nutrients from living hosts (other living organisms).
