chemistry
sodium reacts completely with 0.142kg of chlorine, forming 234g of sodium chloride. What mass of sodium reacted? I know that for chemical changes the amounts should end up being equal, but I don't know how to set up the problem.

Math
What is the pattern for 3, 19, 99, 499, 2499

chemistry
So do I set this up as: 8.86*10^11m (1Gm/10^9m)=8.86*10^11/10^9 since my meters cancel? Which then gives me 8.86^20

chemistry
I am still lost on setting up the last 2.

chemistry
The other two questions that I can not set up for conversions is 8.86*10^11m converted to gigameters 1.57*10^-10m converted to picometers

I am having a hard time with this one not sure how to set up the problem. A gas can holds 1.7gal of gasoline. What is this quantity in cubic centimeters? I know that 1gal=3.785L I know that 1L=1000cm^3 I have tried 1.7gal*3.785L/1gal=6.4345cm^3. I just can not figure out what ...

What word means having no form?

math 7th
divide 6 into 48.. you get 8

How do I calcualte these conversions? 8.4cm = m 1333.8g=kg 119cm=mm 2391mL=L 3.22Mm=km 4.68fs=ps 8.86*10^11=Gm 1.57*10^-10m=picometers 381cm=in 94mm=in 5.0L=q 132kg=lbs
