382.75 is the temperature of the 0.750 mol of an ideal gas occupy a volume of 35.9 L at 114 kPa.
Explanation:
Given:
number of moles (n) = 0.750
volume of the gas = 35.9 litres
pressure on the ideal gas = 114 kPa or 1.125 atm
R (gas constant) = 0.0821J/Kmole
Absolute temperature of gas in celcius =?
the equation for the ideal gas is
PV = nRT
putting the values in the above equation:
T =
=
= 655.907
655.9 kelvin is the temperature of the ideal gas.
To convert this unit of kelvin into degree celcius:
K-273.15 = C
655.9 - 273.15
= 382.75 degrees
382.75 degrees celcius is the temperature of the ideal gas.
Answer: A convex lens is used to converge ligtht.
Explanation:
A concave lens is a lens that is thicker on the ends than in the middle. As consequence of this, a concave lens diverges (separate) the rays of light. A concave lens is also called diverging lens.
A convex lens is is thicker in the middle than on the ends. As consequence of this, a convex lense converge the parallel rays that pass through it. A convex lens is also called converging lens.
Answer:
The correct answer is B. A compound that is a hydrogen ion acceptor in an acid-base reaction
Different wavelength are involved.
Explanation:
If magnesium burns with a bright white flame, one can conclude that different wavelengths accompany the electron transitions for the magnesium atom.
- When an atom burns, the electrons in it are excited.
- They give out characteristic light commensurate with their energy.
- A white light is made up of different combinations of wavelength of radiations.
- When we see a white light we can infer that different joined together in the emission observed.

Answer:
Explanation:
No, it is preposterous and possible to expect or to disengage and isolate a basic and neutral compound by 1M NaOH in DCM. Since neutral compounds do not react with NaOH, and NaOH itself is a base so it can't react with another base to yield salt. For that reason, we just need a corrosive element i.e an acid.
So; In DCM, we can't utilize 1M NaOH rather than 1M HCI for isolation and detachment of neutral and basic compounds.
