4 0

Answer:

51.88 grams

Explanation:

make it in ratio form

Al=27×2=54.

54:48

(54/102)×98

=51.88 grams

O=16×3=48

(48/102)×98

=46.12 grams

Find the volume of 2.40 moles of gas whose temperature is 50.0°C and whose pressure is 2.00 atm.
DanielleElmas [232]
PV=nRT
n=2.4 moles
T=273.15+50=323.15K
P=2*101325=202650 Pa
R=8.31


Solve for V:
V=nRT/P=2.4*8.31*323.15/202650=.032m^3

Which of the following leads to a higher rate of diffusion?
miv72 [106K]
<h3><u>Answer;</u></h3>

Higher velocity of particles

<h3><u>Explanation;</u></h3>

The diffusion rate is determined by a variety of factors which includes;

  • Temperature such that the higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly and the diffusion rate will be high.
  • Concentration gradient such that the greater the difference in concentration, the quicker the rate of diffusion.
  • Higher velocity of particles increases the diffusion rate as this means more kinetic energy by the particles and hence the particles will mix and move faster, thus higher diffusion rate.
