pOH scale is used to determine the basicity of a solution
pH scale is used to determine the acidity of a solution
pH and pOH are related in the following formula
pH + pOH = 14
once pOH is known we can calculate pH
pOH = 8.7
pH = 14 - 8.7
pH = 5.3
pH of the solution is 5.3
when pH is less than 7 the solution is said to be acidic
when pH is equal to 7 then solution is neutral
when pH is more than 7 then solution is basic
the pH of the solution here is 5.3 which is less than 7, therefore solution is acidic
acidic solution with pH of 5.3
2. molecules under the apex of the curve
3. molecules under the right end of the curve
4. all molecules under curve "T2"
Answer : The correct option is, (3) molecules under the right end of the curve
Explanation :
Evaporation : It is type of process in which the phase changes from liquid state to gaseous state below the boiling temperature of the liquid.
As we know that the higher the temperature of the liquid , the more will be the molecule escaping into the gaseous phase than the lower temperature .
So, the molecules under the right end of the curve are likely candidates for evaporation.
Hence, the correct option is, (3)
Answer: molecules under the right end of the curve
Explanation: smart
(2) 236 K (4) 371 K
Answer:
3= 310. k
Explanation:
how to convert 37 Celsius to Kevin is to add 273.15 to 37 then you get 310.15 Kevin then you round that number to the nearest whole and you get 310 and that is your answer. please give me brainiest
