Answer:
Explanation:
2-methyl-3-ethylpentane | C8H18 | ChemSpider.
Boiling Point: 115.3±7.0 °C at 760 mmHg
Molecular Formula: C8H18
Density: 0.7±0.1 g/cm 3
Enthalpy of Vaporization: 32.9±0.0 kJ/mol
Answer: 44.8 L
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 
of particles.
Standard condition of temperature (STP) is 273 K and atmospheric pressure is 1 atm respectively.
To calculate the moles, we use the equation:
1 mole of 
occupies volume = 22.4L at STP
Thus 2 moles of magnesium react with=
Thus the volume of 
molecules of nitric oxide gas is 44.8 L.
A cation is smaller than its parent atom.
Therefore, here a sodium ion is smaller than the neutral sodium atom.
Reason: Since the sodium atom loses an electron to form an electropositive ion(cation), its nuclear charge increases(the number of protons exceeds the number of electrons) and the orbital electrons are pulled with a greater energy.
Thus,the sodium ion shrinks in size.
