Answer:
The final volume of the sample of gas
= 0.000151 
Explanation:
Initial volume
= 200 ml = 0.0002
Initial temperature
= 296 K
Initial pressure
= 101.3 K pa
Final temperature
= 336 K
Final pressure
= K pa
Relation between P , V & T is given by

Put all the values in the above equation we get

= 0.000151 
This is the final volume of the sample of gas.
Using a more concentrated HCl solution and Crushing the CaCO₃ into a fine powder makes the reaction to occur at a faster rate.
<u>Explanation:</u>
CaCO₃(s) + 2HCl(aq) → CaCl₂(aq) + H₂O(aq) + CO₂(g)
When calcium carbonate reacts with hydrochloric acid, it gives out carbon-dioxide in the form of bubbles and there is a formation of calcium chloride in aqueous medium.
The rate of the reaction can be increased by
- Using a more concentrated HCl solution
- Crushing the CaCO₃ into a fine powder
When concentrated acid is used instead of dilute acid then the reaction will occur at a faster rate.
When CaCO₃ is crushed into a fine powder then the surface area will increases thereby increasing the rate of the reaction.
The correct answer is sodium chloride. NaCl. Also known as table salt.
I hope this helps you.
Explanation:
According to the given data, the turnover number can be calculated as follows.
Turnover number = 

Therefore, moles of
hydrolyzed is as follows.
Moles of
hydrolyzed =
=
= 0.00682 moles
Now, moles of
hydolyzed per second is calculated as follows.
Moles of
hydolyzed per second =
= 
And,
Moles of enzyme =
=
=
moles
Therefore, the value of
is as follows.

=
per second
=
per minute
=
per minute
Thus, we can conclude that the turnover number (
) of carbonic anhydrase (in units of
) is
per minute.
For 6, celsius to kelvin is simply adding 273.15
So, 297+273.15 = 570.15 kelvin
