Answer: The correct option is 2.
Explanation: There are two types of nuclear reactions:
1) Nuclear fission: These reactions are defined as the reactions in which a heavier unstable nuclei breaks into two or more smaller stable nuclei.
2) Nuclear fusion: These reactions are the ones where two smaller nuclei fuse together or combine together to form a larger nuclei.
In the question, we need to find the fusion reaction which forms elements heavier than helium.
Option 1: In this fusion reaction occurs but the nuclei is Helium itself.
Option 2: In this also fusion reaction occurs and the nuclei is heavier than Helium which is Neon.
Option 3 and Option 4: These two reactions are nuclear fission reactions of Uranium-235 because one heavier element is breaking into more than 2 products.
Hence, the correct option is 2.
There are four choices to choose from in regards with this problem and fortunately I know the answer to the said question:
Listed below are the choices:
a.) 6.0 L of H2(g) at STP
b.) 12.0 L of CO2(g) at STP
c.) 18.0 L of HCI(g) at STP
d.) 24.0 L of O2(g) at STP
The correct answer is b. 12.0 L of CO2 (g) at STP
Note:
STP or (Standard Temperature and Pressure) - most commonly used when performing calculations on gases (e.g. gas density)
<u>Answer:</u> The amount of time required by chlorine gas to effuse is 19 seconds.
<u>Explanation:</u>
Rate of a gas is defined as the amount of gas displaced in a given amount of time.
To calculate the rate of diffusion of gas, we use Graham's Law.
This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:
So,
We are given:
Moles of iodine gas = 0.15 moles
Moles of chlorine gas = 0.15 moles
Time taken by iodine gas = 36 seconds
Molar mass of iodine gas = 254 g/mol
Molar mass of chlorine gas = 71 g/mol
Putting values in above equation, we get:
Hence, the amount of time required by chlorine gas to effuse is 19 seconds.
