The final volume : 3.4 L

<h3>Further explanation</h3>

Charles's Law  

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}

V₁=3300 ml

T₁=63 + 273=336 K

T₂=78+273=351 K

the final volume :

\tt V_2=\dfrac{V_1.T_2}{T_1}\\\\V_2=\dfrac{3300\times 351}{336}\\\\V_2=3447.3~ml\rightarrow 2~sig.~fig.\rightarrow 3.4~L

Identify the term that applies to each definition.
Illusion [34]

Answer:

A. Reference blank

B. Cuvettes

C. Transmittance

D. Absorbance

E. Wavelength

Explanation:

A reference blank is a sample prepared using the solvent and any other chemicals in the sample solutions, but not the absorbing substance.

A square-shaped container, typically made of quartz, designed to hold samples in a spectrophotometer is known as Cuvettes.

A measurement of the amount of light that passes through a sample or percentage of light transmitted by the sample, with the respective intensities of the incident and transmitted beams is called Transmittance.

The measurement of the amount of light taken in by a sample is known as Absorbance

The wavelength is also the distance travelled by the wave during a period of oscillation. In spectrophotometry, the unit is inversely proportional to energy and commonly measured in nanometers

If the reaction is at dynamic equilibrium at 500 K, which statement applies to the given chemical system?
Alenkinab [10]

The correct option is this: THE CONCENTRATION OF THE PRODUCTS AND THE REACTANTS DO NOT CHANGE.

A reversible chemical reaction is said to be in equilibrium if the rate of forward reaction is equal to the rate of backward reaction. At this stage, the concentrations of the products and the reactants remain constant, that is, there is no net change in the concentration even though the reacting species are moving between the forward and the backward reaction.

Which of the following would not cause an increase in the pressure inside a sealed container of neon gas?
r-ruslan [8.4K]

The pressure in a sealed container means the volume of container is fixed

so we cannot change the volume of container hence gas

The other factors which can affect the pressure are

a) moles of gas : if we increase the moles of gas the pressure of gas will increase

b) Temperature: if we increase the pressure of gas the pressure of gas will increase due to increase in kinetic energy

So the following cannot increase pressure

a) decrease in moles of gas

b) decrease in temperature of gas
