Answer : The value of 'R' is 
Solution : Given,
At STP conditions,
Pressure = 1 atm
Temperature = 273 K
Number of moles = 1 mole
Volume = 22.4 L
Formula used : 
where,
R = Gas constant
P = pressure of gas
T = temperature of gas
V = volume of gas
n = number of moles of gas
Now put all the given values in this formula, we get the values of 'R'.


Therefore, the value of 'R' is
.
The correct order of steps during the formation of an ionic bond
- Electrons are transferred
- Ions are attracted to each other
<h3>What is Ionic bonding?</h3>
This is the type of bonding which occurs as result of transfer of electrons
and is also regarded as electrovalent bonding.
When the electrons are transferred , ions form which then gets attracted
to each other and results in the formation of a compound.

Answer:
The cylindrical tube can hold 0.215 cubic decimeters of blood.
Explanation:
Diameter of the cylindrical tube = d = 4.5 cm
r = d/2 ,r = 2.25 cm
Height of the cylindrical tube = h = 13.5 cm
Volume of the cylinder = V = 



The cylindrical tube can hold 0.215 cubic decimeters of blood.
Answer: 300mm
Explanation:
30cm x (10mm/1cm) x <em>(1mm/1mm)</em> = 300mm
<em>Btw, I'm not sure about the </em><u><em>(1mm/1mm).</em></u>
