When 1 mol of Cr2O3 has 2 mol of Cr, So we can easily get the number of moles of Cr in 2.16 mol of CrO3 by:
Cr → Cr2O3
2 mol→ 1 Mol
X → 2.16 Mol
So X (the no. of mol of Cr ) = 2 Mol * 2.16 Mol = 4.32 Mol
Answer:
0.2 dm³
Explanation:
Concentration = no. of moles of solute / volume
Concentration: 0.30 mol dm-³
no. of moles of solute: 0.060mol
0.3 = 0.06 / v
v = 0.2 dm³
Answer:
[OH-] = 0,071 mol/L
Explanation:
pOH = -log[OH-]
[OH-] = 10^-pOH = 10^-1.15 = 0,071 mol/L
The correct option is (d) Nonane.
Nonane parent chain of the following compound.
<h3>What are hydrocarbons?</h3>
Hydrocarbons are any of a group of organic compounds that exclusively contain the elements carbon (C) and hydrogen (H) (H). The structural framework of the molecule is formed by a number of interactions between the hydrogen and carbon atoms.
<h3>What is hydrocarbon made of?</h3>
Hydrocarbons, which are only composed of carbon and hydrogen, make up the majority of crude oil, refined petroleum hydrocarbons (including gasoline, diesel, kerosene, fuel oil, and lubricating oil), coal tar, creosote, dyestuff, and pyrolysis waste products.
