Answer:
The correct answer is option C.
Explanation:
On increasing the pH of the blood the hydronium ions concentration will decrease which will result in decrease in concentration of hydronium ions at the equilibrium state of hydrogen carbonate.
Le-Chatelier's principle:
This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
According to Le-Chatelier's principle , on decrease in a concentration of the product the equilibrium moves in forward correction to re-establish itself.
So, on increasing the pH, the hydronium ions concentration will decrease which results in disassociation of more hydrogen carbonate to maintain the pH of the blood.
Hence, the correct answer is option C.
False
Explanation: Carbon is the central atom which has valency of 4 and can form 4 bonds to complete its octet. Each chlorine has valency of 1 and can form only one bond to complete its octet. Thus carbon can bond with four chlorine atoms through sharing of electrons to form four single bonds. Thus it cannot contain a double bond.
Answer: Volume of benzene is: 22.8 cm cubed
Answer:
The image is not accurate because
the heavier atoms are moving faster than the lighter ones
but the lighter ones must move faster than the heavier ones.
Explanation:
The image depicts the atoms of two different elements; atoms of lighter and heavier elements.
And the rate of diffusion (movement of atoms) of an element is inversely proportional to the square root of its molecular.
⇒ As the weight increases, the rate of diffusion (movement of atoms) decreases.
And as the weight decreases, the rate of diffusion (movement of atoms) increases.
so, heavier atoms move slowly compared to lighter atoms.
The image is not accurate because
the heavier atoms are moving faster than the lighter ones
but the lighter ones must move faster than the heavier ones.
