<span>Explain the difference between a weak acid and a strong acid according to the Arrhenius theory his question in english</span>
To calculate the mass of Fe formed in a) we get first the limiting reactant between Fe2O3 and CO. Given the masses, the ratio of Fe2O3 is 1.33 while that of CO is 1.67. Hence the limiting reagent is Fe2O3. The mass of Fe formed is 148.98 grams. In b, the needed CO is only 112.04 grams. Hence, the excess is 27. 96 grams.
Its molecular formula : C₆H₁₂O₆
<h3>Further explanation </h3>
The empirical formula(EF) is the smallest comparison of atoms of compound forming elements.
A molecular formula(MF) is a formula that shows the number of atomic elements that make up a compound.
(EF) n = MF
its empirical formula is CH₂O
CH₂O : 12+2+16=30
![\tt [30]n=180\rightarrow n=6\\\\(CH_2O]_6=C_6H_{12}O_6](https://tex.z-dn.net/?f=%5Ctt%20%5B30%5Dn%3D180%5Crightarrow%20n%3D6%5C%5C%5C%5C%28CH_2O%5D_6%3DC_6H_%7B12%7DO_6)
Answer:
H-F> H-O> O-F
while H-H is nonpolar.
Explanation:
The bond is polar when electronegativity difference of both bonded atom is greater than 0.4.
Electronegativity values of O. F and H are
O = 3.4
H = 2.2
F = 3.98
For O-F
3.98 - 3.4 = 0.58
For H-F
3.98 - 2.2 = 1.78
For H-O
3.4 - 2.2 = 1.2
For H-H
2.2 -2.2 = 0
So H-H is nonpolar.
