<h3><u>Answer;</u></h3>
Ionic
Powdered sports drink is<u> ionic </u>
<h3><u>Explanation;</u></h3>
- <em><u>Sports drinks are beverages whose purpose is to help athletes replace water, electrolytes, and energy before and after training or competition.</u></em>
- Sport drinks contain may contain water, fuel and electrolytes which are used to regulate fluid balances in the body. Electrolytes are molecules that have electrical charge called ions, such as calcium , potassium, sodium and chloride ions.
- <em><u>Ionic compounds are made up of ions, that is positively charged ions and negatively charged ions which are joined together by ionic bonds. Electrolyte in sport drinks forms ionic bonds.</u></em>
Carbon dioxide and oxigen
Answer:
λ = 2.38 × 10^(-7) m
Explanation:
We are given the work function for palladium as 503.7 kJ/mol.
Now let's convert this to KJ/electron.
We know from avogadro's number that;
1 mole of electron = 6.022 × 10^(23) electrons
Thus,
503.7 kJ/mol = 503.7 × 1/(6.022 × 10^(23)) = 8.364 × 10^(-22) KJ/electron = 8.364 × 10^(-19) J/electron
Formula for energy of a photon is;
E = hv
Where;
h is Planck's constant = 6.626 × 10^(-34) J.s
v is velocity
Now, v = c/λ
Where;
c is speed of light = 3 × 10^(8) m/s
λ is wavelength of light.
Thus;
E = hc/λ
Making λ the subject, we have;
λ = hc/E
λ = (6.626 × 10^(-34) × 3 × 10^(8))/(8.364 × 10^(-19))
λ = 2.38 × 10^(-7) m
