option A Hydrogen will have the greatest rate of effusion beacuse it has the least mass among all
Calcium hydroxide dissolves and dissociates according to:
Ca(OH)₂(s) ⇄ Ca²⁺(aq) + 2 OH⁻(aq) therefore the answer is PH7
Answer : The temperature in degree Celsius is, 
Explanation :
The conversion used for the temperature from Kelvin to degree Celsius is:

where,
= temperature in Kelvin
= temperature in centigrade
As we are given the temperature in Kelvin is, 2.7
Now we have to determine the temperature in Kelvin.



Therefore, the temperature in degree Celsius is,
