<h2>Increase of reaction rate</h2>
Explanation:
- It is observed that when the concentration of acetylcholine remains constant in the reaction of an aqueous solution, the speed of the enzyme-catalyzed reaction or the formation of the product increases with increasing concentrations of substrate.
- The reaction rate is directly proportional to the concentration of acetylcholine.
- At very low concentrations of acetylcholine, there is a small increase in the concentration of the substrate which results in a large increase of the rate in reaction.
1.) is157.7 g
<span>moles Fe = 209.7 g/ 55.847 g/mol=3.75
the ratio between Fe and CO is 2 : 3
moles CO = 3.75 x 3 /2 =5.63
mass CO = 5.63 mol x 28.01 g/mol=157.7 g
2.) is </span><span>1.06 moles

<span>2.12/2 x 24 = 25.44dm^3 hydrogen = 1.06 moles </span>
1.06 X 6.02x10^23 = 1.204x10^24 molecules of hydrogen.

Answer: The freezing point of 3.46 gram of a compound X in 160 gram of benzene is 
Explanation:
The relation of density and molar mass is:
where
d = density = 3.27 g/ L
P = pressure of the gas = 773 torr = 1.02 atm (760 torr = 1atm)
M = molar mass of the gas = ?
T = temperature of the gas = 
R = gas constant = 
The relation of depression in freezing point with molality:
= depression in freezing point = 
= 
= freezing point constant = 5.1
m = molality = 
Thus the freezing point of 3.46 gram of a compound X in 160 gram of benzene is
Answer:
<em>The correct option is C) All of the genetic information comes from one parent.</em>
Explanation:
The description in the paragraph tells that Astrammina rara are unicellular organisms and their offspring born are identical to the parent cell.
Asexual reproduction can be described as a method of reproduction in which a parent cells produces two offsprings which are identical to the parent cell. Asexual reproduction is the common mode of reproduction in unicellular organisms.
Hence, the description shows that Astrammina rara reproduce by this method and hence all of the information will arise from one, single parent.
There are four naturally occurring isotopes of iron, Fe-54, Fe-56, Fe-57, and Fe-58.
