Answer:
<h2>252.9 kPa</h2>
Explanation:
The new pressure can be found by using the formula
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
From the question we have
We have the final answer as
<h3>252.9 kPa</h3>
Hope this helps you
Answer:
O begins to boil
Explanation:
When the vapor pressure of a liquid is equal to the atmospheric pressure, the liquid suddenly begins to boil.
- At this point the boiling point of the liquid has been reached.
- Further addition of heat energy will cause the liquid to boil vigorously
- Subsequently evaporation will start from the surface of the boiling liquid.
- The atmospheric pressure is the ambient pressure measured with the respect to the sea level pressure.
Answer:
2 moles
Explanation:
number of mole =mass /molar mass
mass=36
molar mass=(2*1)+16=18
therefore, no of mole =36÷18 =2
Answer:
ii) the energy of the electron on the outer shell
iv) the overall size of an orbital
Explanation:
There are four quantum numbers to define the position and energy level of an electron in an atom
a) Principal : The principal quantum number (n) is to know the energy of an electron in an atom and its possible distance from the nucleus.
b) Azimuthal: It refers to the shape of the subshell or orbital of the electron and thus the angular distribution.
c) Magnetic: It refers to the number of orbits and their orientation in the subshell.
d) spin: It refers to the spin of the electron.
