Answer:
B
Explanation:
Shows actual sacrifice in order to train and be the best.
Answer:
4.525% is the percentage by volume of oxygen in the gas mixture.
Explanation:
Total pressure of the mixture = p = 4.42 atm
Partial pressure of the oxygen =
Partial pressure of the helium =
(Dalton law of partial pressure)
According Avogadro law:
(At temperature and pressure)
Volume occupied by oxygen gas =
Total moles of gases = n = 1 mol
Total Volume of the gases = V
Percent by volume of oxygen in the gas mixture:
Butane and isobutane are structural isomers. Isobutane is produced by the isomerization reaction of butane.
CH3CH2CH2CH3--(t°,AlCl3)-›CH3CH(CH3)-CH3.
They have the same chemical formula C4H10.But structural formulas are different
Butane CH3CH2CH2CH3
Isobutane CH3CH(CH3)CH3
Isobutane has methyl radical.
The correct answer is fracture formation.
Fracture formation is not an indication of a chemical change.
Gas production, energy transfer are Precipitate information indications of a chemical change.
A chemical change is an irreversible process wherein there are rearrangements of the atoms in the molecules of a compound, resulting in the formation of a new compound with new chemical properties or composition.
A fracture is a fault line that divides rocks into two or more pieces. A fracture is a geological formation. Fracture is most often seen as crevice or deep fissures in rocks.
