Answer:
37.65mL
Explanation:
Given parameters:
density of liquid Z = 0.9237g/mL
Mass of liquidZ + mass of cup = 50.7g
Mass of cup= 15.92g
Volume of liquid Z in cup=?
Solution:
Density is the mass per unit volume of a substance. It is mathematically expressed as shown below:
Density =
To find the volume of liquid Z, we know the density of the liquid but we dont know the mass yet.
Mass of liquidZ = 50.7g - mass of cup = 50.7g - 15.92g = 34.98g
Therefore:
Volume of liquidZ =
=
= 37.65mL
<u>Answer:</u> Enzymes enhances the rate in the same order.
<u>Explanation:</u>
Catalyzed reactions are defined as the reactions in which a catalyst is used.
A catalyst is a substance which increases the rate of the reaction and does not participate in the reaction. It can be recovered at the end of the reaction. It decreases the activation energy of the reaction.
The rate of catalyzed reactions is always greater than the rate of uncatalyzed reactions.
Enzymes are the natural catalysts which are present in the animal body to increase the rate of some reactions.
Thus, they enhance the rate of both slow and fast uncatalyzed reaction at the same rate.
You would need 1000 liters
Answer:
1) Increase
2) Decreases
3) increases
4) Increase
Explanation:
These questions can only be answered by considering the principle which states that, "When a constraint such as a change in concentration, pressure or volume is imposed on a reaction system in equilibrium. The system will readjust itself in order to annul the constraint."
Now, if more reactants are added, the equilibrium position will shift towards the right, If more products are added, the equilibrium position will shift to the left.
Similarly, the removal of H2S causes the O2 concentration to increase since the equilibrium position now shifts to the left.
Also, addition of O2 causes H2S to be removed as the equilibrium moves to the right.
