Answer:
0.2335320064 mi/min
Explanation:
1 km/h = 0.0103561865 mi/min
1 mi/min = 96.56064 km/h
For conversion:
22.55 km/hr = 22.55 x 0.0103561865 mi/min = 0.2335320064 mi/min
Answer:
is the correct choice that is option A.
Explanation:
An electron has
times the mass of a proton, but an equal and opposite negative charge.
Lets
is any element represented here.
Where
is the number of protons as well as its atomic number.
And
is the mass number which is the number of protons and neutrons in any atom.
Note: We know that Hydrogen
is devoid of neutron,so number of neutrons in a Hydrogen atom is zero.
Then
is also a representation of single proton.
So
is the right choice that is option A.
Caffeine is not optically active because it is a planar heterocycle. When you say optically active, it means that compounds have molecules which are chiral. Chirality is the property of molecules as a result of its structure. And when you say planar heterocycle, molecules are flat and the ring should contain atoms located in a similar plane.
The heat of vaporization of aluminium at 25 °C is 315.8 kilojoules per mole.
The sublimation is the phase change of a substance from <em>solid</em> to <em>gas</em>, the fusion is the phase change of a substance from <em>solid</em> to <em>liquid</em> and the vaporization is the phase change of a substance from <em>liquid</em> to <em>gas</em>. The heat of vaporization is the difference between the heat of sublimation and the heat of fusion, that is to say:


The heat of vaporization of aluminium at 25 °C is 315.8 kilojoules per mole.
