On the left side. The alkali metals are group 1, the alkaline earth metals are group 2, and the transition metals are groups 3-12.
About 7.1 litres all you have to do is to divide divide the volume value by 1000
Answer : The mass of vanadium(V) oxide will be 
Explanation : Given,
Number of atoms of 
= 
Molar mass of = 181.88 g/mole
In , there are 2 atoms of vanadium and 5 atoms of oxygen.
First we have to determine the moles of .
As, 
number of vanadium atom present in 1 moles of
So, number of vanadium atom present in 
moles of
Now we have to determine the mass of .
Therefore, the mass of vanadium(V) oxide will be
B
Relative to the observer, the objected, emitting visible light will appear red in color because the wavelength of light is stretched hence acquiring longer wavelength in the visible electromagnetic spectrum (remember red light has the longest wavelength in the visible light spectrum).
Explanation:
Conversely, if the object was moving towards the observer, it would appear blue in color (blue shift) because the relative wavelength of the visible light would be ‘compressed’ (remember this is always relative to the observer) hence the wavelength would be shorter (and blue light has the shortest wavelength in the visible light spectrum).
Both these phenomenons are classified under Doppler shift effect of waves. It also occurs in our daily lives. When a wailing ambulance approaches you, the pitch of the wailing sounds is higher (relative to you). However, when the ambulance passes you and begins stretching away from you, the pitch of the wailing goes low.
