Answer:
C₆H₁₈
Explanation:
Let's say x is the subscript of carbon and y is the subscript of hydrogen. We know from the empirical formula that the ratio of x to y is 2 to 6.
x / y = 2 / 6
We also know from the molar mass that:
12.01x + 1.01y = 90.21
Solving the system of equations:
2y = 6x
y = 3x
12.01x + 1.01(3x) = 90.21
12.01x + 3.03x = 90.21
15.04x = 90.21
x = 6
y = 3x
y = 18
The molecular formula is therefore C₆H₁₈.
Answer:
Niels Bohr, refined the model of an atom by proposing a quantized shell structure atomic model in order to describe how the electrons are able to maintain stable orbits around the nucleus
Based on the predictions of classical mechanics the electron motion of the Rutherford model was unstable as the electrons where expected to have lost some energy during motion and thus having to come rest in the nucleus
According to the modification by Neils Bohr in 1913, electrons move in shells or orbits of fixed energy and emission of electromagnetic radiation takes place only when electrons changes the orbit in which they move
Explanation:
The energy<span> per </span>photon<span> is proportional to the </span>frequency<span> of the radiation when considered as waves, ie inversely proportional to the </span>wavelength. Double the wavelength<span>, halve the </span>photon energy<span>. This means that long </span>wavelength<span> radiation (radio waves) has low </span>photon energy<span> and so does not penetrate matter.</span>
The name of this alkane is with central carbons are bonded to c h 3 is 2-methylbutane.

What is alkane?</h3>
Alkanes belong to the family of saturated hydrocarbons with carbon carbon single bond.
For the given alkane;
CH₃ H
CH₃ - C - C - CH₃
H H
Thus, the name of this alkane is with central carbons are bonded to c h 3 is 2-methylbutane.
