5.Through using a telescope Galileo Galilei was able to prove the theories of sciences Isaac newton
6. He believe that the speed of an object motion is proportional to the force being applied and inversely proportional to the density of the medium he reason that the object moving in a void would move in definitely fast and thus any and all objects

Move the decimal point from 0, 250.000 <- this is the same as 250 to between 2 and 5.
I had to move two spaces.
2.5^2
I hope this helps!

Balanced equation: 2Al+Fe2O3–> Al2O3+2Fe
Using mole calculations you can find that 10g of Al produces 24.3g of Fe under the conditions described
C is the correct answer (CaF2) (sorry dont have subscript)
Explanation: synthesis reaction forms a compound and calcium reacting with fluorine produces Calcium Fluoride (CaF2) chemical name
