Answer : The mole ratio of to is 1 : 1.
Explanation :
Balanced chemical reaction : It is a chemical reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.
The balanced chemical reaction is:
By the stoichiometry of the reaction we can say that 1 mole of reacts with 1 mole of to give 1 mole of .
From this we conclude that the mole ratio of to is 1 : 1.
Hence, the mole ratio of to is 1 : 1.
Answer : The emperical formula of hydrocarbon is .
Solution : Given,
Mass of = 11.1 g
Mass of = 5.11 g
Step 1 : convert given mass in moles.
Moles of = = = 0.2522 moles
Moles of = moles of C = 0.2522 moles
Moles of = = = 0.2838 moles
Moles of = moles of H = 0.2838 × 2 = 0.5677 moles
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For C = 0.2522/0.2522 = 1
For H = 0.5677/0.2522 = 2.25
C : H = 1 : 2.25
To make the ratio as a whole number multiply numerator and denominator by 4.
Ratio of C : H = = 4 : 9
The mole ratio of the element is repersented by subscripts in emperical formula.
Therefore, the Emperical formula =
Answer:
true
Explanation:
CO has two C-O bonds. The dipoles point in opposite directions, so they cancel each other out. Thus, although CO₂ has polar bonds, it is a nonpolar molecule. Therefore, the only intermolecular forces are London dispersion forces.
Answer:
1. If you put a bucket of water out in the Sun on a hot, windy day, what will happen to the water level in the bucket? The water level will stay the same since the water is protected from the wind. The water level will only go down if the wind makes water splash out of the bucket
