Answer:
A.
Explanation:
The pancreas is one of the biggest insulin producers in the body, and testes release, among other hormones, testosterone. :)
Answer:
A. The equilibrium will shift towards the right, towards the formation of products
B. The concentration of hydrogen gas will decrease as more of it is used in the formation of products
C. Increasing the temperature at which the reaction is performed will increase the concentration of C2H4, the product of the reaction.
Explanation:
The given reaction is an exothermic reaction as it requires the addition of extra energy of about 52.4KJ in the form of heat for the reaction to proceed towards product formation.
According to L' Chtler principle, when an external constraint is applied to A given system in equilibrium, equilibrium position will shift so as to annul the effect ofnthe constraint imposed on the system.
Therefore, the answers tonthe questions above are given below as follows :
A. The equilibrium will shift towards the right, towards the formation of products in order to remove the effect of the additional heat since the forward reaction is endothermic.
B. The concentration of hydrogen gas will decrease as more of it is used in the formation of products .
C. Increasing the temperature at which the reaction is performed will increase the concentration of C2H4, the product of the reaction as the equilibrium will shift towards the right; formation of products.
Seawater found to be seeping up through the canyon floor is why
scientists think Grand Canyon was once covered by an ocean.
Grand cayon is located in Arizona, United States and comprises of a lot of
fossil records and rocks which makes it one of the best sites for geological
study.
The Grand cayon was found to be seeping through its floor which made
scientists think it was once covered by an ocean years ago.

<h3><u>Answer;</u></h3>
Higher velocity of particles
<h3><u>Explanation;</u></h3>
The diffusion rate is determined by a variety of factors which includes;
- Temperature such that the higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly and the diffusion rate will be high.
- Concentration gradient such that the greater the difference in concentration, the quicker the rate of diffusion.
- Higher velocity of particles increases the diffusion rate as this means more kinetic energy by the particles and hence the particles will mix and move faster, thus higher diffusion rate.
Answer:
Speed, 
Explanation:
The device which is used to accelerate charged particles to higher energies is called a cyclotron. It is based on the principle that the particle when placed in a magnetic field will possess a magnetic force. Just because of this Lorentz force it moves in a circular path.
Let m, q and V are the mass, charge and potential difference at which the particle is accelerated.
The work done by the particles is equal to the kinetic energy stored in it such that,
v is the speed with which the particles enter the cyclotron
So,
So, the speed with which the particles enter the cyclotron is . Hence, this is the required solution.
