Answer:
0.12 dm³ or 120 cm³
Explanation:
Hi there!
so first step find the number of moles
number of moles = mass ÷ Ar ( since o is an element and when it is alone, it is a diatomic molecule {O2} )
number of moles = mass ÷ Ar
number of moles = 0.16 ÷ ( 16 × 2 )
= 0.16 ÷ 32
= 5 × 10 ( power -3)
1 mol of O2 = 24 dm³ or 24 000 cm³
5 × 10 ( power -3) of O2 = (5 × 10 ( power -3)) × 24
= 0.12 dm³
or
= (5 × 10 ( power -3)) × 24 000
= 120 cm³
Answer:
See explanation below
Explanation:
In this case we have the starting reactant which is the ethine, In the first step reacts with NaNH₂, a strong base. This base will substract the hydrogen from one of the carbon of the ethine, and form a carbanion. This will react with the propane bromide, displacing the bromine and forming a 5 carbon chain with the triple bond on the carbon 1 and 2.
In the second step, reacts with the lindlar catalyst to do a reduction, and form a double bond between carbon 1 and 2. In essence, compound A is similar to compound B.
Finally B reacts with water in acid and makes a addition reaction, and form an alcohol.
The whole process can be seen in the picture below.
Hope this helps
Answer:
<h2>Density = 3.9 g/ mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 43 g
volume = 11.1 mL
Substitute the values into the above formula and solve for the density
That's
We have the final answer as
Density = 3.9 g/ mL to one decimal place
Hope this helps you
Yea ma’am yea sir I am in the process and I’m just getting my car back from work I just saw it and when I got back I went to the doctor for the day so Lillian
The formula unit of compounds formed depends on the valency of the combining ions.
The formula unit is the smallest unit of an ionic substance that gives us a picture of the ratio in which ions are combined in the ionic compound.
Usually, the formula unit is written based on the valency of the ions.
For the ions listed;
Li+ and 02- forms Li2O
Mg2+ and S2- forms MgS
A13+ and CI- forms AlCl3
Na+ and N3- forms Na3N
