Chemistry

Answer:

he key difference between plant and animal cells lies in the structural differences. Plant cells are rectangular wheres animal cells are round and plant cells contain chloroplasts, a cell wall, and vacuoles while animal cells do not.

Another difference is that plant cells have chloroplasts while animal cells do not. Chloroplasts, rich in chlorophyll, absorb light and conduct photosynthesis, providing the cell with the energy it needs.

The third is the fact that the plant cell doesnt require much nutrients as an animal cell would because for a plant  it uses Glucose for food as though animal require protien several vitamins water,and iron and vitamin b3

Animal cells are round, plant cells are circle (most of them) Plant cells have a rigid cell wall that surrounds the cell membrane. Animal cells do not have a cell wall.

What defines a mixture?
erica [24]

B is your best answer because a mixture is when two or more things combine but not chemically.

You can still take the noodles, you take the fish or meat out still, you take the broth away to.

Dinitrogen pentoxide can be made by the reaction of nitrogen with oxygen. Consider the reaction
Rom4ik [11]
The only reactants are Nitrogen and Oxygen and the only product is dinitrogen pentoxide. Following the law of conservation of mass, the total amount of reactants must equal the total amount of products. Thus, the total mass of dinitrogen pentoxide:

Free Energy
ratelena [41]

Answer:

a) galvanic cell

b)electrolytic cell

c) i) K=6.27x10'34

ΔG°=198790 J

ii) K=3.58x10'-34

ΔG°= 191070 J

d) E°=0.278 v

ΔG°= -26827 J

Explanation:

a) There are two kinds of an electrochemical cell, the first is called "galvanic cells", and the second "electrolytic cell".

The fuel cells are capable of produce electric energy through chemical reactions. These reactions are often spontaneous. So, the galvanic cell has a negative value for Gibbs free energy.

b) The electrolytic cell increases the value of Gibbs energy, to positive values, due to the reactions are not spontaneous.

c) i) look image attached

ii) k = look image attached

ΔG° = -nFE° = - 6 X 95500 J/vmole x (-0.33 v)

ΔG° =-191070

d) E°= 0.0592 v/n x lg K

E°= 0.0592V / 1 X log 5.0X10'4

E°= 0.278 v

ΔG° = -nFE° = -1 x 96500 J/ vmole x 0.278v

ΔG° = -26827 J
