Answer:
There is a temperature of 111 K required.
Explanation:
Step 1: Data given
Volume of hydrogen gas = 6.34 L
Pressure = 1.52 atm at 298 K
The volume of the gas at a pressure of 0.720 atm is 4.98 L
Step 2:
(P1*V1)/T1 = (P2*V2)/T2
⇒ with P1 = the pressure of the hydrogen gas = 1.52 atm
⇒ with V1 = the volume of the hydrogen gas = 6.34 L
⇒ with T1 = the temperature of the hydrogen gas = 298 K
⇒ with P2 = the changed pressure of the gas = 0.720 atm
⇒ with V2 = the changed volume of the gas = 4.98 L
⇒ with T2= the temperature of the gas at 0.720 atm and 4.98L
(1.52*6.34)/298 = (0.720*4.98)/T2
0.0323 = 3.5856/T2
T2 = 110.88 K ≈111K
There is a temperature of 111 K required.
The general formula for cycloalkanes is <span>CnH2n .

Answer:
The order of conductivity will be as follows:
> NaBr > Benzoic acid > sugar
Explanation:
ionizes to give one Al and three ions and thus, produces 4 ions.
Sugar does not ionizes and hence does not produce ions.
Benzoic acid is a weak organic acid and ionizes to produce two ions; and .
Sodium bromide is a strong electrolyte and ionizes to produce 2 ions.
As sodium is strong electrolyte, therefore, its conductance will be higher than benzoic acid.
Therefore, the order of conductivity will be as follows:
> NaBr > Benzoic acid > sugar
they send the radiation through the cords
V=0.7 l
c=0.33 moles/l
n(HCl)=v·c
n(HCl) = 0.7 l · 0.33 moles/l = 0.231 moles
0.231 moles of HCl are present
