name the inorganic compounds that are oxides?

Answer 4

carbon dioxide
nitric oxide
magnesium oxide
hydrogen peroxide

Question 5

name the inorganic compounds that are not oxides?

Answer 5

nitrates
phosphates
sulfates

Question 6

function of carbon dioxide?
Co2

Answer 6

• plant extract Co2 from the air, then made into sugar molecules and O2 to feed themselves
• animals use O2 to produce energy for themselves. they give off carbon which combines with O2 in the air

• when added to a liver it produces oxygen gas and water

Question 10

function of nitrates?
NO3

Answer 10

• plants absorb NO3 during photosynthesis, then converted to nitrogen

Question 11

function of phosphates?
PO43-

Answer 11

each of the bases in DNA and RNA has nucleotides. one nucleotide has to have one phosphate group

Question 12
