Answer: -
1.34 L
Explanation: -
Initial Pressure P 1 = 39.1 bar
Initial Temperature T 1 = 643 K
Let the initial volume be V 1.
Final pressure P 2 = 87.0 bar
Final temperature T 2 = 525 K.
Final volume V 2 = 0.492 L
Using the equation


Plugging in the values
We have
V 1 = 87 bar x 0.492 L x 643 K / (39.1 bar x 525 K)
= 1.34 L
Thus, a gas is contained in a thick-walled balloon. When the pressure changes from 39.1 bar to 87.0 bar the volume changes from 1.34 L to 0.492L and the temperature changes from 643K to 525K
The fluoride ion in the reaction has been the acceptor of the hydrogen. Thus, the fluoride ion has been the Brønsted Lowry base.
<h3 /><h3>What is the Brønsted Lowry acid and base concept?</h3>
The Brønsted Lowry acid and base concept can be described based on the proton acceptor and donor. The Brønsted Lowry acid has been the proton donor, and the Brønsted Lowry base has been the proton acceptor.
The Arrhenius concept is based on hydrogen and hydroxide donors. The Arrhenius base has been the hydroxide donor, and the Arrhenius acid has been the hydrogen donor.
Since the fluoride ion has been the proton acceptor in the reaction, it has been the Brønsted Lowry base.

Answer:
d
Explanation:
Isomers are molecules that have the same molecular formula(the same number of each atom), but different structural formulas
in this case both have the formula C2H5O
Answer:
The Inert Pair effect renders Pb(II) as the more stable oxidation state of lead
Explanation:
SnBr4 + PbBr2 ---> SnBr2 + PbBr4
SnBr2 + PbBr4 ---->
The Inert pair effect is mostly observed between group 15-17 in the periodic table. It leads to stability of the lower oxidation state of an element.
The reason for the Inert pair effect is that the s electrons become Inert due to poor shielding of the d and f-electrons. The Inert pair effect is a tendency of the s electrons not to participate in bonding (remain an Inert pair).
Owing to the Inert pair effect, Pb II is more stable than Pb IV
