Protons have a mass of 1
Neutrons have a mass of 1
So 13*1 + 14*1 = Mass number 27
Answer:The reaction absorbs 8100 J of energy from the surroundings as it proceeds.
Explanation:
Answer:
decreased by a factor of 10
Explanation:
pH is defined in such a way that;
pH= −log10(H)
Where H represents the concentration of Hydronium or Hydrogen ions
Given that pH is changed from 1 to 2,
By rearranging the above formula , we get 10−pH = H
- if pH=1,H=10−1=0.1M
- if pH=2,H=10−2=0.01M
Therefore, 0.1/0.01 = 10 and 0.1 > 0.01
Hence, the concentration of hydronium ions in the solution is decreased by a factor of 10
Answer:
Temperature is the condition of the atmosphere at any given time and place
and climate is the weather over a long period of time
