Answer:

125 carbon atoms are from proline are present in the protein.

Explanation:

Molecular formula of proline = C_5H_9NO_2

Number of carbon atoms =  5

If a human protein has 25 proline monomers.

Number of proline molecules = 25

Number of carbon atoms in 25 molecules of proline :

5\times 25 = 125

125 carbon atoms are from proline are present in the protein.

zysi [14]

Answer:

Pros

1)Ethanol Creates Positive Energy Balance

2) Ethanol is a renewable source of energy

3)made from multiple raw materials

4) Green House gas emission reduction

Cons

1) Price fluctuations becauset

The volume of Ethanol production is season dependent

2) has lower mileage

3) corrosive effect because ethanol can absorb water

Explanation:

The amount of green house gas produced in burning Ethanol is minimal compared to that produced in burning gasoline.

Also the corrosive effect on metallic part of vehicle since most likely since ethanol is water friendly

By what factor does the rate change in each of the following cases (assuming constant temperature)? (a) A reaction is first orde
Papessa [141]

Answer:

a) 2

b) 1/4

c) 9

Explanation:

a) for a first order reaction in reactant A

r initial = k*[A initial]

then if the concentration is doubled [A final ]= 2*[A initial]  , then

r final = k*[A final ] = 2* k*[A initial] = 2*r initial

then the velocity changes by a factor of 2

b) for a second order reaction in reactant B

r initial = k*[B initial]²

then if the concentration is halved: [B final ]= [B initial]/2  , then

r final = k*[B final ]²  = k*( [B initial]/2 )²  =k* [B initial]² /4 = r initial /4

then the velocity changes by a factor of 1/4

c) for a second order reaction in reactant C

r initial = k*[C initial]²

then if the concentration is tripled : [C final ]= 3* [C initial]  , then

r final = k*[C final ]²  = k*( 3*[C initial] )²  =k* [C initial]² *9 = 9 * r initial  

then the velocity changes by a factor of 9
