Answer:
Propane tanks are most commonly referred to by their water capacity volume, and propane tanks are normally filled to 80% of its water capacity. For example, a 120-gallon tank will hold approximately 100 gallons of propane when completely full. Since propane is stored in a liquid state under pressure, it needs room to
Answer:
600K
Explanation:
PV=nRT
T=PV/nR
= 1.6atm* 15.0L/ 0.5mol*0.0821LatmK^-1mol^-1
=600K
We can solve this problem using the long hand solution, wherein we 1 by 1 analyze the different equilibrium reactions or by simply using the Henderson Hasselbach equation. The equation is
pH = -log(pKa) + log (salt/acid)
since the acid and the salt have the same concentration, the log (salt/acid) term is equal to zero.
thus
pH = -log(1.73*10-5)
pH = 4.76
please be careful with the negative sign
(D) At equilibrium, the concentration of the products will be much higher than the concentration of the reactants.
<u>Answer:</u> The correct answer is Option A, Option B and Option D.
<u>Explanation:</u>
Molecular compound are defined as the compounds which are formed by the sharing of electrons between the atoms. They are also known as covalent compounds. They are of two types:
- <u>Polar covalent compound:</u> This compound is formed when difference in electronegativity between the atoms is present. When atoms of different elements combine, it results in the formation of polar covalent bond. For Example: etc..
- <u>Non-polar covalent compound:</u> This compound is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. For Example: etc..
We know that: Like dissolves like. This means that polar solvent will dissolve polar molecules and non-polar solvent will dissolve non-polar molecules
Water is a polar compound. So, it will dissolve only polar molecules.
The given substance 'X' is a molecular compound. It may be polar or non-polar.
So, it may be soluble in water or may not be soluble.
Electrolyte are defined as the compound which conduct electricity when dissolved in water. They conduct electricity because of the ions they dissociate into.
Thus, substance 'X' is not an electrolyte.
Hence, the correct answer is Option A, Option B and Option D.
