Answer:
1& 4
Explanation:
1. The average kinetic energy of the particles in a substance determines the substance's temperature.
4. How fast a substance's particles are moving determines how hot or cold the substance is.
For conversion of kPa and atm, the relationship is 1 atm = 101.325 kPa. So for 20000 kPa, the atm number is 20000/101.325=197.4 atm.
It would be c because it has to get hot so it is absorbing the heat not releasing it
It would be the same amount. So, 45 ml of NaOH is required to be added to the 45 ml of HCI to neutralize the acid fully. Here is a brief calculation:
Firstly, here is your formula: M(HCI) x V(HCI) = M(NaOh) x V(NaOH)
With the values put in: 0.35 x 45 = 0.35 x V(NaOH)
= 45 ml.
There is 45 ml of V(NaOH)
Let me know if you need anything else. :)
