Answer:
39.6 g
Explanation:
The equation of the reaction is;
2Mg(s) + O2(g) --------> 2MgO(s)
To obtain the limiting reactant;
Number of moles in 26.4 g of Mg = 26.4g/24 g/mol = 1.1 moles
If 2 moles of Mg yields 2 moles of MgO
1.1 moles of Mg yields 1.1 * 2/2 = 1.1 moles of MgO
Number of moles in 26.4 g of O2 = 26.4 g/32g/mol = 0.825 moles
If 1 mole of O2 yields 2 moles of MgO
0.825 moles of O2 yields 0.825 moles * 2/1 = 1.65 moles of MgO
Hence Mg is the limiting reactant.
Theoretical yield of MgO = 1.1 moles of MgO * 40 g/mol = 44 g
Percent yield = 90%
Percent yield = actual yield/theoretical yield * 100
Actual yield = Percent yield * theoretical yield/100
Actual yield = 90 * 44/100
Actual yield = 39.6 g
Answer:
I got 1.14 mol So3 as the answer
hopefully if this could help
The larger/bulky groups will be in equatorial positions. There is less ring strain in the equatorial position.
The IUPAC name of this compound is diamminecarbonylchloroIridium ..

Answer:
3.32 m
Explanation:
<u>We have:</u>
<em>f = frequency of the electromagnetics waves = 9.05x10⁷ Hz (frequency of the electromagnetic waves of FM broadcast throughout the world)</em>
<em>c = is the speed of the electromagnetics waves = 3x10⁸ m/s (speed of light)</em>
We can find the wavelength of the electromagnetics waves as follows:
Therefore, the wavelength of a certain FM radio station broadcasts electromagnetic waves is 3.32 m.
I hope it helps you!
