The air pressure creates a vacuum in the straw that pulls the air into the liquid.
The mass stays the same because if you have the same amount of steam then it can't change. The volume will get slightly smaller because the average kinetic energy of the molecules is less, so they move around less, so they take up less space. The particles are moving less fast.
Answer:
Pb(C2H3O2)2 + KI ----> PbI2 + KC2H3O2
Explanation:
all the numbers are written as subscripts
Answer:
28%
Explanation:
concentration=(solute mass/solution mass)*100
C=concentration
md-solute mass
ms-solution mass
the solution mass is equal to the sum of the solute and solvent mass
ms=3.82+1.49=5.31lb
c=1.49/5.31 * 100=0.28*100=28%
