Answer: Catalyst

Explanation: Catalyst is a substance which enhances the speed of Chemical reaction without consuming in the Reaction and it is regenerated after completion of Reaction and it is reused further cycle of reaction.

So catalyst reduces the activation energy by speed up the reaction

Predict the effect of the following changes in the reaction CO (g) + 2 H2 (g) <-> CH3OH (g) + energy.
Sophie [7]

Explanation:

  Equation of reaction:

             CO   + 2H₂    ⇒   CH₃OH   +   energy

a.  An increase in pressure:

A change in pressure affects only equilibrium involving a gas or gases. Le Chatelier's principle can be used to predict the direction of displacement.

An increase in pressure on an equilibrium system will shift the position of equilibrium to the side having smaller volume and vice-versa

       CO   + 2H₂    ⇒   CH₃OH   +   energy

          3 moles                  1 moles

An increase in pressure will favor the forward reaction to be favored.

b. Addition of H₂:

An in concentration of a specie favors the direction that uses up that specie and lowers its concentration.

Addition of hydrogen gas increases the concentration of amount of substances reacting.

To annul the effect of the reactant, more the product is given. The equilibrium shifts in the forward direction.

Anna35 [415]

Answer;

= 64561.95 g/mole

Explanation;

mass of Fe in 100g = .346g

= .346 / 55.8452 moles

= 0.0061957 moles  

These represent 4 moles of Fe in the molecule so moles of hemaglobin

=  0.0061957/4  

= 0.0015489 moles  

these are in 100 g so mass of 1 mole = 100 / 0.0015489

= 64561.95 g / mole

molar mass of hemoglobin = 64561.95 g/mole
