Given the speed of light (3.00 × 108 m/s) and a wavelength 5.9 × 10-7 m, what is the frequency?
Cerrena [4.2K]
Wavelength x Frequency = Speed

So, 5.9 x 10^-7 x F = 3 x 10^8

Rearranging the equation, we get:
F = (3 x 10^8)/(5.9 x 10^-7) = 5.08 x 10^14 Hz

Choose any metal atom from Group 1A, 2A, or 3A. What charge will it adopt when it ionizes?​
Ksenya-84 [330]

Answer:

Positive charge.

Explanation:

Hello!

In this case, since elements belonging to groups 1A, 2A and 3A are mostly metals, we infer they have the capacity to lose electrons and therefore they become positively charged.

Some examples may be:

Na^+\\\\H^+\\\\Ca^{2+}\\\\Al^{3+}\\\\Sr^{2+}

Best regards!

The effect of baking powder solution on dilute hydrochloric acid solution​
Lostsunrise [7]

Baking powder solution has an effect on a diluted hydrochloric acid solution by causing the release of carbon dioxide from sodium bicarbonate, a component of baking soda.

One molecule of backing soda + one molecule of hydrochloric acid yields one molecule of sodium chloride (table salt) + one molecule of carbon dioxide + one molecule of water.

HCl + NaHCO₃=NaCl+H₂CO₃

However, carbonic acid is quite unstable:

H₂CO₃ = CO₂ + H₂O

HCl + NaHCO₃ = NaCl + H₂O (Water) + CO₂.

Effervescence, which is a fast bubble formation, is how liquid releases CO2.
