Calculate the frequency
Ber [7]
Given: wavelength of Nitrogen laser (∧) = 337.1 nm = 337.1 X 10^-9 m

We know that, Energy of photon (E) = hc/∧ = hv
where, v = frequency of photon and c = speed of light = 3 X 10^8 m/s

Thus, v = c/∧ = (3 X 10^8)/ (337.1 X 10^-9) = 8.899 X 10^14 s-1.

Answer: F<span>requency of nitrogen laser = </span>8.899 X 10^14 s-1.

Assume that Na+ is being transported across a membrane via facilitated diffusion. Which of the following conditions would allow
lesya [120]

Answer:

<h2>4. Na+ diffusing toward the side of the membrane with Cl− and 50% less Na+.</h2>

Explanation:

Facilitated diffusion is a type of transport mechanism in which the special proteins are involved and play an important role in the transport of the atoms, ions or molecules. This mechanism is based on the electrochemical gradient differences. When this difference increase, then the transport of the sodium takes place because sodium ions are chemically attracted by chloride ions. In a facilitated diffusion process, no energy requirement takes place. This process occurs along the concentration gradient.

which are correct formulas for ionic compounds? for those that are not correct, give the correct formula and justify your answer
skelet666 [1.2K]

Answer:

Ionic compounds have a metal and nonmetal.

Ionic compounds are made up of ions.

Explanation:

You did not provide any formulas for me to correct, but:

  • ionic compounds tend to have metals and nonmetals. (EX: NaCl)You can look at the periodic table to see which elements are metals and which are not.
  • ionic compounds are made up of ions. Ions are elements that have a charge (Like Cu^{2+} or  O^{-}). To have a correct ionic compound, make sure that the ions inside of it "cancel" each other out.

       EX: Na has a +1 charge. Cl has a -1 charge. When they are paired up,      they successfully cancel each other out (become neutral) and become the ionic compound NaCl.

The chart below shows you the charge of each element. Make sure the charge of the elements in an ionic compound "cancel" each other out.

The very last chart shows the metals and nonmetals
