Hello there!
In this case, according to the given information and the chemical reaction, whereby iron and hydrochloric acid react in a 1:2 mole ratio, it is firstly necessary to calculate the moles of iron (II) chloride from each reactant in order to figure out the limiting reactant:
In such a way, we infer the maximum moles of FeCl2 product are yielded by HCl, for which it is the limiting reactant. Finally, we calculate the grams of product by using its molar mass as shown below:

The equation relating velocity and wavelength is written below:
v = λf
where λ is the wavelength in m while f is frequency in 1/s.
Let's determine first the frequency from the speed of light:
c = distance/time, where c is the speed of light equal to 3×10⁸ m/s
3×10⁸ m/s = (300 mm)(1 m/1000 mm)/ time
time = 1×10⁻⁹ seconds
Since f = 1/t,
f = 1/1×10⁻⁹ seconds = 10⁹ s⁻¹
Thus,
v = (795×10⁻⁹ m)(10⁹ s⁻¹)
v = 795 m/s

<em><u>Freezing is the process that causes a substance to change from a liquid to a solid. Freezing occurs when the molecules of a liquid slow down enough that their attractions cause them to arrange themselves into fixed positions as a solid.</u></em>
Hydrocarbons that lack π bond are called saturated hydrocarbons or alkanes
<h3>Hydrocarbons</h3>
- Hydrocarbon is an organic compound consisting of hydrogen and carbon.
- Hydrocarbons is an examples of 14 group hydrides.
- Hydrocarbons are colorless and hydrophobic.
- Their odors are usually like gasoline or lighter fluid.
- In oil and gas industry, the hydrocarbon in term, combines petroleum and natural gas they are the two naturally occurring phases of hydrocarbon.
<h3>Alkanes</h3>
- Alkanes also konwn as parafins
- They are called as saturated hydrocarbons
- Alkanes contain hydrogen and carbons arranged in tree structure
- Alkanes have two main sources petroleum and natural gas.
Therefore, Hydrocarbons that lack π bond are called saturated hydrocarbons
