Answer:
It is false.
Soaps are sodium and potassium salts of fatty acids.
Synthetic detergents on the other hand, are salts of long-chain alkyl sulfuric acids (sulfonic acid) or alkylbenzenesulfonic acids, rather than carboxylic acids.
Explanation:
Soaps are sodium and potassium salts of fatty acids. Soaps are made by the process of saponification in which an alkali is added to a fat or oil and then boiled to produce a salt of the fatty acid known as soap. The alkali used may be sodium or potassium hydroxide. However, the advantage of potassium soaps is that are more soluble and lather more easily.
<em>Salts of sulfonic acids or alkylbenzenesulphonates are known as detergents</em>. Unlike soaps, they are not salts of fatty acids and are more soluble in hard water, because the polar sulfonate ion of detergents does not readily bind to calcium and other ions found in hard water. Thus, detergents are more widely used as cleansing agents than soaps

<u>Answer:</u> The pressure of carbon dioxide gas is 11 atm
<u>Explanation:</u>
To calculate the pressure of gas, we use the equation given by ideal gas equation:
PV = nRT
where,
P = pressure of the gas = ?
V = Volume of gas = 25 L
n = number of moles of gas = 10 mole
R = Gas constant = 
T = temperature of the gas = 325 K
Putting values in above equation, we get:
Hence, the pressure of carbon dioxide gas is 11 atm
The equilibrium expression shows the ratio
between products and reactants. This expression is equal to the concentration
of the products raised to its coefficient divided by the concentration of the
reactants raised to its coefficient. The correct equilibrium expression for the
given reaction is:<span>
<span>H2CO3(aq) + H2O(l)
= H3O+(aq) + HCO3-1(aq)
Kc = [HCO3-1] [H3O+] / [H2O] [H2CO3]</span></span>
Tap water contains many dissolved ions that are required to carry an electric current, whilst distilled water contains no or relatively low amounts of dissolved ions. the absence of ions in the distilled water accounts for the low to zero conductivity of the water
