that would be physical change cuz your only changing it PHYSICALLY ya know wat im sayin...

a physical change is a change that does not change the composition of the substance. a physical change does not change the molecules of the substance. (they mean the same thing) but no new substance is made from a physical change it stays the same substance as it is...and probably.....always...wooooooo

-exp would be: cutting, tearing, folding, painting, melting, freezing, mixing, and evaporating.

carbon disulfide is formed by the reaction of coke (carbon) with sulfur dioxide. how many moles of cs2 will be generated if 8.0
Murrr4er [49]
5C₂ + 4SO₂ ------>  2CS₂  +  8CO

mole ratio of C₂  :  CS₂
                 =   5   :    2

∴ since C₂ contains 8 moles 

  then CS₂ contain   ( \frac{8}{5} )  *  2  moles
                            
                             =  3.2 moles

Find the volume of a gas at STP, if its volume is 80.0 mL at 109 kPa and -12.5°C.​
exis [7]

Answer:

= 913.84 mL

Explanation:

Using the combined gas laws

P1V1/T1 = P2V2/T2

At standard temperature and pressure. the pressure is 10 kPa, while the temperature is 273 K.

V1 = 80.0 mL

P1 = 109 kPa

T1 = -12.5 + 273 = 260.5 K

P2 = 10 kPa

V2 = ?

T2 = 273 K

Therefore;

V2 = P1V1T2/P2T1

     = (109 kPa × 80 mL × 273 K)/(10 kPa× 260.5 K)

     <u>= 913.84 mL</u>
