<u>Given:</u>
Time taken by the electromagnetic radiation, t = 33 fs
<u>To determine:</u>
The distance (d) travelled
<u>Explanation:</u>
Time taken = 33 fs (femtosecond)
1 fs = 10⁻¹⁵ s
Thus t = 33 *10⁻¹⁵ s
Speed of electromagnetic radiation = 3*10⁸ m/s
Distance = Speed * Time = 3*10⁸ ms-1 * 33*10⁻¹⁵ s = 99*10⁻⁷ m
Ans: distance traveled = 9.9*10⁻⁶ m
Density is given by the equation D=m/V, were D is density, m is mass in grams, and V is volume in cubic centimeters.
In this problem, we have density and we have mass so we can plug into the equation and solve for V.
38.6=270.2/V
<em>*Multiply both sides by V*</em>
38.6V=270.2
<em>*Divide both sides by 38.6*</em>
V=7
The volume of the gold nugget is 7cm3.
Hope this helps!!

Answer:
This is due to more hydrogen bonding in ethylene glycol than it is in isopropyl alcohol
Explanation:
The boiling point of isopropyl alcohol is 82.4 °C it contains only a single OH group, hence intermolecular hydrogen bonding is solely responsible for it's boiling point, whereas Ethylene glycol (CH2OHCH2OH) contains 2-OH group and both intermolecular and intramolecular hydrogen bonding are responsible for the higher boiling point of ethylene glycol at 198 °C.
Answer:
They will create an ionic bond.
Explanation:
The atom with the one valence electron will lose its one, because it's a metal and metals will lose electrons to become stable. The nonmetal (with 7 valence electrons) will gain that electron, therefore creating a stable octet for the nonmetal, making the compound stable.
