Answer : The volume of container will be 44.8 L
Explanation :
At STP condition,
The temperature and pressure are 273 K and 1 atm respectively.
As we know that at STP, 1 mole of substance occupies 22.4 L volume of gas.
As per question,
1 mole of nitrogen gas occupies 22.4 L volume
and,
1 mole of neon gas also occupies 22.4 L volume
Thus, total volume will be:
Total volume of container = 22.4 + 22.4 = 44.8 L
Hence, the volume of container will be 44.8 L
The statement that is not true about the exothermic reaction is that the potential energy of the product is higher than the potential energy of the reactant. That is option D.
<h3>What is an exothermic reaction?</h3>
An exothermic reaction is the reaction that releases heat to the environment which causes increase in the immediate environment.
The characteristics of exothermic reaction include the following:
- Activation energy of the forward reaction is smaller than the activation energy of the reverse reaction.
- Heat is released to the environment during reaction.
Since there is release of heat, the product will have a lower energy than the reactant.
Therefore, the statement that is not true about the exothermic reaction is that the potential energy of the product is higher than the potential energy of the reactant.

#SPJ1
The molar mass of the unknown compound is calculated as follows
let the unknown gas be represented by letter Y
Rate of C2F4/ rate of Y = sqrt of molar mass of gas Y/ molar mass of C2F4
= (4.6 x10^-6/ 5.8 x10^-6) = sqrt of Y/ 100
remove the square root sign by squaring in both side
(4.6 x 10^-6 / 5.8 x10^-6)^2 = Y/100
= 0.629 =Y/100
multiply both side by 100
Y= 62.9 is the molar mass of unknown gas
Reduction reactions are those reactions that reduce the oxidation number of a substance. Hence, the product side of the reaction must contain excess electrons. The opposite is true for oxidation reactions. When you want to determine the potential difference expressed in volts between the cathode and anode, the equation would be: E,reduction - E,oxidation.
To cancel out the electrons, the e- in the reactions must be in opposite sides. To do this, you reverse the equation with the negative E0, then replacing it with the opposite sign.
Pb(s) --> Pb2+ +2e- E0 = +0.13 V
Ag+ + e- ---> Ag E0 = +0.80 V
Adding up the E0's would yield an overall electric cell potential of +0.93 V.
