Answer: A. Acids have a slippery feel.
Explanation:
Acid : It is a substance that has ability of donating proton or hydrogen ion, .
The properties of an acid are :
Acids are sour in taste.
The texture of an acid solution is sticky.
It changes the color of the litmus paper to red.
It react with a metal to give compound and hydrogen gas.
Base : It is a substance that has ability of donating hydroxide ion, .
The properties of an base are :
Base are bitter in taste.
The texture of a base solution is slippery.
It changes the color of the litmus paper to blue.
It does not react with a metal.
Thus bases have slippery nature and not acids.
Answer : The energy evolved when it burned was,
Solution :
First we have to calculate the moles of hydrogen gas by using ideal gas equation.
where,
P = pressure of gas = 1 atm
V = volume of gas =
T = temperature of gas =
R = gas constant = 0.0821 Latm/moleK
n = number of moles of gas
Now put all the given values in the above formula, we get the moles of hydrogen gas.
Now we have to calculate the amount of energy evolved.
The combustion reaction of hydrogen will be,
The enthalpy of combustion of hydrogen is -286 KJ/mole. (standard value)
As 1 mole of hydrogen gas burned it evolved energy = -286 KJ
So, of hydrogen gas burned it evolved energy =
Therefore, the energy evolved when it burned was,
