Draw the major monobromination product formed by heating the following alkane with bromine.

yawa3891 [41]

A monobromination reaction of an alkane involves an alkane and bromine. The position of the hydrogen atom that will be substituted by the bromine free radical will depend on the order of the alkane. The bromine will attach to the carbon that has the most substituents.

A hydrogen atom in an excited state can be ionized with less energy than when it is in its ground state. What is n for a hydroge

Molodets [167]

Explanation:

It is known that formula for the ionization energy of hydrogen atom is as follows.

E = $\frac{13.6 eV}{n^{2}}$

or, n = $\sqrt{\frac{13.6}{E}}$

The value of energy is given as 0.544 eV. Therefore, we will calculate the value of n as follows.

n = $\sqrt{\frac{13.6}{E}}$

= $\sqrt{\frac{13.6}{0.544 eV}}$

= 5

Thus, we can conclude that n equals to 5 for a hydrogen atom if 0.544 eV of energy can ionize it.

Calculate the density of a substance with a mass of 0.0500g and volume of 6.40mL, round to the correct number of significant num

lozanna [386]

Density=mass/volume
Mass = 0.0500g
Volume = 6.40mL

0.0500g/6.40mL = 0.0078g/mL
