Answer:

Atoms like sodium, with only one or two electrons in a valence shell that needs eight electrons, are most likely to give up their valence electrons to achieve a stable state.

A student observes the chemical process described by this equation:

choli [55]

Answer:

Both are equal

Explanation:

Mass of starting material i.e Aluminium is $4.480 * 10^{-23}$ grams

The weight of oxygen is $2.65 * 10^{-23}$

There are 4 atoms of aluminium and 3 atoms of oxygen

Thus, the total mass of starting material is

$4 *$ mass of one atom of aluminium $+ 6 *$ mass of one atom of oxygen

$4 * 4.480 * 10^{-23} + 6* 2.65 * 10^{-23}$

$35.1 * 10^{-23}$ grams

Mass of new substance is also equal to

$4 *$ mass of one atom of aluminium $+ 6 *$ mass of one atom of oxygen

$4 * 4.480 * 10^{-23} + 6* 2.65 * 10^{-23}$

$35.1 * 10^{-23}$ grams

Question 22 A VHF television station assigned to channel transmits its signal using radio waves with a frequency of . Calculate

aleksklad [387]

The question is incomplete, here is the complete question:

A VHF television station assigned to channel transmits its signal using radio waves with a frequency of 66.0 MHz. Calculate the wavelength of the radio waves. Round your answer to 3 significant digits.

Answer: The wavelength of the radio waves is 4.54 m

<u>Explanation:</u>

To calculate the wavelength of light, we use the equation:

$\lambda=\frac{c}{\nu}$

where,

$\lambda$ = wavelength of the light

c = speed of light = $3\times 10^8m/s$

$\nu$ = frequency of light = $66.0MHz=66.0\times 10^6s^{-1}$

Putting the values in above equation, we get:

$\lambda=\frac{3\times 10^8m/s}{66.0\times 10^{6}s^{-1}}=4.54m$

Hence, the wavelength of the radio waves is 4.54 m

Draw the mechanism for the addition of methylmagnesium bromide to propanoyl chloride (CH3CH2COCl) to give 2-methyl-2-butanol.

Ghella [55]

Answer:

Reaction mechanism has been given below

Explanation:

Propanoyl chloride contains an electrophilic carbonyl center to give nucleophilic acyl substitution reaction by removing Cl group with a strong nucleophile like methylmagnesium bromide.
Two equivalent of methyl magnesium bromide react with cabonyl center followed by protonation of negatively charged oxygen atom gives 2-methyl-2-butanol.
In the first step, nucleophilic acyl substituion occurs. In the second step, nucleophilic addition occurs. In the third step, protonation occurs.
Reaction mechanism has been shown below.
