1.As you move from left to right across a period,the number of valence electrons
Vitek1552 [10]
<span>1. The number of valence electrons increases as you go from left to right across a period. This is because the number of electrons increases, so another electron will be added to the outer shell.

2. Group 6A elements will have 6 valence elecrons, while Group 2A elements only have 2, therefore Group 6A elements have more valence electrons that Group 2A elements.

3. Fluorine has a smaller atomic size than the other halogens (Cl, Br, I), so its valence electrons are nearer to its nucleus. This means that the attractive forces are stronger, so when another electron (from another atom) draws near the F atom, it is more likely that the electron will be pulled toward the nucleus and react with the F atom</span>.

The distance measured between five successive crests of a wave motion executed by a photon of an electromagnetic radiation is 2.
Jet001 [13]

Answer:

6.25 ×10^10 Hz

Explanation:

If the distance between five successive crests is 2.4 cm, then the distance between each crest is 2.4/5 = 0.48 cm or 0.0048 m or 4.8 ×10^-3 m

Since the velocity of a wave is given by;

v= λf

Where;

λ= wavelength of the wave

f= frequency of the wave

But λ= distance between successive crests = 4.8 ×10^-3 m

v= 3×10^8 ms-1 (speed of electromagnetic waves in vacuum)

f= v/λ

f= 3×10^8 ms-1/4.8 ×10^-3 m

f= 0.625 ×10^11 Hz

f= 6.25 ×10^10 Hz

A 0.45-g sample of aspirin is decomposed into its constituent elements and found to contain 0.27 g C, 0.020 g H and 0.16 g O
andre [41]

Explanation:

Given parameters:

Mass of aspirin = 0.45g

Mass of C = 0.27g

Mass of H = 0.02g

Mass of O = 0.16g

Unknown:

Mass percentage of the constituents = ?

Solution:

To find the mass percent, ensure that sum of the mass of the elements  add up to the that of the given mass of aspirin

 Total mass = 0.27 + 0.02 + 0.16 = 0.45g

Now express each of the given percentages to that of the total one.

mass percent of C = \frac{0.27}{0.45} x 100 = 60%

mass percent of H = \frac{0.02}{0.45} x 100 = 4.4%

mass percent of O = \frac{0.16}{0.45} x 100  = 36%
