um im not sure if this is rigt but i think that the ranges would be -5, -3, -1, 1, 3. your equation is in slope intercept form so you start with -1. if you would go with the slope which would be 2, then your next number up is 1, then 3. it can also go down which is where you ...

i dont know sorry
November 17, 2008

so CO3 would be that carbon has 6 electrons and oxygen has 8 meaning that c has 4 electrons in the outer shell and o has 6. they dont make an even 8 so idk how they make and ion because they like to have a full outer shell and those combining wouldnt do that. so imnot sure how...
November 17, 2008

hmmm...you would have the same # of protons and electrons in its normal state, but an ion- the element gives up an ion and another element takes that ion...what is carbonate...carbon and what?
November 17, 2008

it depends....is the carbon giving an electron or taking one?

i dont get your formula but if you have 3 oz of oil for 1/2 gallon of gas then you need 6 oz of oil for 1 gallon. you need 5 gallons so you multiply 6*5. you need 30 oz of oil.
