Question

Sugar is a pure substance, but it is not an element.

Which sentences support this statement?

Hint: Consider the definition of an element.

Select all that apply.

a The process of cellular respiration uses sugar and provides energy to cells.
b Plants make sugar using water (H2O), carbon dioxide (CO2), and sunlight.
c Sugar crystals dissolve in water, but the smaller particles are still sugar.
d Animals break down sugar through cellular respiration.
I think its c and d because elements cannot be broken down.

Answer 1

not c, since it specifically states that the sugar is unchanged. It might be an element.
b states that sugar is built from other parts, so it must not be an element.
you are right about d

Answer 2

thank you
