Answer:
1 mole of water and 6.022 ×10^23 water molecules
The amount of heat required is calculated using the below formula
Q(heat) =M(mass) xC(specific heat capacity)x delta T (change in temperature)
change in the temperature in kelvin=(35+273)- (25 +2730= 10K
c= 2.48 j/g/k
mass= 54.0 g
Q= 54.0 g x 2.48 j/g/k x 10k = 1339.2 joules is required
When titrating a strong monoprotic acid and KOH at 25 degrees Celcius, the pH will be approximately equal to 7.00. Since a strong acid and a strong base reacts through a neutralization reaction. The pH of a neutral solution is 7.00. <span />
the number is the mass number
the mass number is the number of nucleons (total number of protons and neautrons in the nucleus) so in hydrogen-3 there are 3 nucleons and as hydrogen has 1 proton, there are 2 neutrons
carbon 12 has 12 nucleons (6 protons and 6 neutrons) and carbn 13 has 13 nucleons (6 protons and 7 neutrons)
Answer:
5. All of the above.
Explanation:
Energy can be extracted from water by gravitational force as done in hydroelectric plants, temperature gradients that creates natural convection processes, the mechanical variations of ocean currents and surface waves, and by nuclear fussion.
