Answer:
i believe its A, potassium iodide in water
Explanation:
Answer:
Explanation:
The Ideal Gas equation is:
(1)
Where:
is the pressure of the gas
the number of moles of gas
is the gas constant
is the absolute temperature of the gas in Kelvin.
is the volume
It is important to note that the behavior of a real gas is far from that of an ideal gas, taking into account that <u>an ideal gas is a single hypothetical gas</u>. However, under specific conditions of standard temperature and pressure (T=0\°C=273.15 K and P=1 atm=101,3 kPa) one mole of real gas (especially in noble gases such as Argon) will behave like an ideal gas and the constant R will be .
However, in this case we are not working with standard temperature and pressure, therefore, even if we are working with Argon, the value of R will be far from the constant of the ideal gases.
Having this clarified, let's isolate from (1):
(2)
Where:
is the absolute temperature of the gas in Kelvin.
(3)
Finally:
Benzyl Amine is synthesized from Toluene in two steps;
Step 1: Bromination of Methyl Group in Toluene: Bromination is carried out on methyl group present on Benzene ring through free radical mechanism by treating toluene with <span>N-Bromosuccinimide (NBS) and Benzyl Bromide is formed.
Step 2: Benzyl Bromide into Benzyl Amine; This step is carried out utilizing a neme reaction "Gabriel Reaction". Benzyl bromide is treated with </span>Potassium Phthalamide and an intermediate is formed which on treatment with Hydrazine produces Benzyl amine.
According to Grahams law the rate of effusion of a gas is inversely proportional to the square root of it's molecular weight. The rate of diffusion is the measure of rate at which two gases mix. From this law we can say that for the two gases carbon monoxide and carbon dioxide, the rate of effusion of carbon monoxide is greater than that of carbon dioxide, this is because carbon monoxide is lighter (28 g) compared to carbon dioxide (44 g).
Answer: Free-energy change of a reaction is a measure of the direction in which a net reaction occurs.
Explanation:
It is known that free energy change is represented by the symbol . Free-energy helps in determining the direction of a chemical reaction like if it is taking place in forward or backward reaction.
For a spontaneous reaction, the standard free-energy change is negative in nature and the reaction will proceed in forward direction.
Thus, we can conclude that free-energy change of a reaction is a measure of the direction in which a net reaction occurs.
