I guess it's correct answer
His kinetic energy is converted into potential energy.
<u>Answer:</u> The final temperature of water is 38.5°C
<u>Explanation:</u>
To calculate the amount of heat released or absorbed, we use the equation:

where,
q = heat absorbed = 1.506 kJ = 1506 J (Conversion factor: 1 kJ = 1000 J)
m = mass of water = 30 g
c = specific heat capacity of water = 4.184 Jl/g.°C
= change in temperature = 
Putting values in above equation, we get:

Hence, the final temperature of water is 38.5°C
Answer:
For the Ag ground-state ion, the type of orbital from which an electron will need to be removed to form the ion of greater positive charge is :
<u>s-orbital</u>
Explanation:
Naming of orbitals :
s = s-orbital
p = p-orbital
d = d-orbital
The electronic configuration of Ag is :
![[Kr]4d^{10}5s^{1}](https://tex.z-dn.net/?f=%5BKr%5D4d%5E%7B10%7D5s%5E%7B1%7D)
The Outermost shell = 5s
so electron should be removed from 5s . there is only 1 electron in 5s -shell. Hence , Ag exist +1 oxidation state.
According to Aufbau's Rule : Electron will be filled first in lower energy orbital.
The electron should be removed first ,from the higher energy orbital.This is because high energy orbitals are away from the nucleus and can be easily removed. The outermost electron feel less attraction of the nucleus
Ionization energy : Energy required to remove the electron from the outermost shell of the element in the gaseous state.

Hence it will form Ag+ cation
<u>Ag+:</u>
![[Kr]4d^{10}](https://tex.z-dn.net/?f=%5BKr%5D4d%5E%7B10%7D)
Outer shell is removed after loss of electron.
Answer : The volume of 1 mole of
and
gases are the same.
Solution: Given,
Moles of
= 1 mole
Moles of
= 1 mole
Moles of
= 2 mole
Formula used for ideal gas is :
P V = n R T
According to the question, the gases are at standard temperature and pressure. So, the volume of gases only depends on the number of moles. This means that the higher the number of moles, higher will be the volume of gas.
The moles of
are more than the moles of
and
. So, the volume of
will be more.
And the moles of
and
are equal. Therefore, their volumes are also equal.
Therefore, the best option is the volume of 1 mole of
and
gases are the same.
