Answer:
There is only one stable atom that does not have neutrons. It is an isotope of the element hydrogen called protium. Protium, which contains a single proton and a single electron, is the simplest atom. All other stable atoms contain some number of neutrons. hope this helps you :)
The order of the reaction with respect to X is 2.
The statements given ;
1. As Concentration of X is in the rate law equation , changing X will have an effect on the rate of the equation.
2. Rate is proportional to X^2
So if concentration of X is doubled, then rate proportional to (2X)^2 = 4X^2
Rate therefore quadruples when X is doubled
This statement is correct
3. If we divide X/2 then the effect to the rate is (X/2)^2 = X/4 . This will reduce the rate by quarter not half . This statement is wrong.
4. If we multiply by 3
Then rate proportional to (3X)^2 = 9X^2
Rate increases by 9 times. This statement is wrong
Answer:
Hydrogen Bonding
Explanation:
Formaldehyde, H2CO, has an oxygen atom which is quite electronegative that means it would attract any atom with a slightly positive charge. Hydrogen in the Hydrogen sulfide (H2S) is attracted by oxygen and hence hydrogen bonding can occur.
