Choose five elements from the periodic table and arrange them according to increasing atomic radii increasing ionization energy increasing electronegativity in increasing metallic property
Answer: J
Explanation: when a object hits something it has a equal and opposite reaction pushing it back
<u>Answer:</u> The correct answer is Option A.
<u>Explanation:</u>
A catalyst is defined as the substance which increases the rate of the reaction without actually participating in the reaction.
This substance decreases the activation energy of the reactants, so as to proceed the reaction at a faster rate by increasing their effective collisions.
It does not affect the concentration of the reactants.
For the given reaction:
If we add NO, which is acting as a catalyst will increase the rate of the reaction to produce the products which is 
Hence, the correct answer is Option A.
1) The gas evolved will be collected over water. Since, over water there is water vapor, the gas collected is a mixture of the gas evolved of the reaction and the water vapour. This mixture of the gas with vapour water (or other vapour if the liquid were other substance) receives the name of wet gas because the gas obtained from the reaction is mixed with vapor from the liquid over which it gas collected.
2) The pressure read for the wet gas is the total pressure (p total), which is the sum of partial pressure of the gas evolved (pH2) plus the partial pressure of vapou (pH2O)
p total = pH2 + pH2O
Then, the partial pressure of the hydrogen is: pH2 = ptotal - pH2O.
So, to find the partial pressure of hydrogen, you need to find the partial pressure of water vapor in a table and subtract it from the total pressure.
3) The data necessary fo find the partial pressure of pH2 is, beside the total pressure read by the instruments, the partial water vapor pressure.
To obtain the partial pressure of water vapor you need the temperature of the system because the data of water vapor pressure are recorded in tables whose entrance is the temperature.
Answer:
B
Explanation:
The equilibrium expression is
[products]/[reactants] and each is raised to its molar coefficient.
So:
[H2}^2[O2]/[H2O]^2
