The new volume of gas Y is 89.38 mL
From the question given above, the following data were obtained:
Initial volume (V₁) = 82.0 mL
Initial temperature (T₁) = 27.0 °C = 27 + 273 = 300 K
Final temperature (T₂) = 54.0 °C = 54 + 273 = 327 K
Pressure = 3 atm = constant
<h3>Final volume (V₂) =? </h3>Since the pressure is constant, we shall determine the final volume of gas Y using the Charles' law equation as follow:
Cross multiply
300 × V₂ = 82 × 327
300 × V₂ = 26814
Divide both side by 300
Therefore, the new volume of gas Y is 89.38 mL

Answer: The final concentration of a solution is 0.350 M
Explanation:
According to the dilution law,
where,
= concentration of concentrated acid solution = 12.0 M
= volume of concentrated acid solution = 35.0 ml
= concentration of diluted acid solution= ?
= volume of another acid solution= 1.20 L = 1200 ml
( 1L=1000ml)
Putting in the values:
The final concentration of a solution prepared by diluting 35.0 mL of 12.0 M HCl to a final volume of 1.20 L is 0.350 M
Beta minus decay will be obtain in the radio-active isotope of Fe-26 power 59.
Whenever there are too many protons or even neutrons in a nucleus, one of the protons and neutrons will turn into the other, which is known as beta decay. During beta minus decay, a neutron transforms into a proton, electron, as well as antineutrino.
→
It can be seen that after the beta minus decay Fe changes into Co.
In beta decay , decrease in atomic number by one unit Fe atom get converted into Co atom.
Neutron-rich nuclei often decay by producing both an electron and an antineutrino.
Therefore, Beta minus decay will be obtain in the radio-active isotope of Fe-26 power 59.
