Answer:The final pressure i.e the pressure of the compressed gas is 273.8mmHg
Explanation:i think
<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles.
4 mol He ( </span>6.022 x 10^23 atoms / mole ) = 2.4088 x 10^34 atoms He
Answer: 1.52 atm
Explanation:
Given that:
Volume of gas V = 10.0L
Temperature T = 35.0°C
Convert Celsius to Kelvin
(35.0°C + 273 = 308K)
Pressure P = ?
Number of moles = 0.6 moles
Molar gas constant R is a constant with a value of 0.0821 atm L K-1 mol-1
Then, apply ideal gas equation
pV = nRT
p x 10.0L = 0.6 moles x (0.0821 atm L K-1 mol-1 x 308K)
p x 10.0L = 15.17 atm L
p = 15.17 atm L / 10.0L
p = 1.517 atm (round to the nearest hundredth as 1.52 atm)
Thus, the pressure of the gas is 1.52 atm
<u>Answer:</u> The half reactions are written below.
<u>Explanation:</u>
Oxidation reaction is defined as the reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.
Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
We are given a chemical cell which is Fe-Sn cell. The half reaction follows:
<u>Oxidation half reaction:</u> 
<u>Reduction half reaction:</u> 
The substance having highest positive 
potential will always get reduced and will undergo reduction reaction. Here, zinc will always undergo reduction reaction will get reduced.
<u>Total cell reaction:</u> 
Hence, the half reactions are written above.
