If we were to classify the pure substance represented by the lewis dot structure seen here, we would classify it as a(n) a) element. b) compound. c) element and ion. d) compound and molecule.

D

Explanation:

This is a water molecule. It is a compound and molecule. Compounds with covenant bonds form molecules.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
