The numerical value of equilibrium constant depends on
TemperatureAs the Temperature increases the value of equilibrium constant decreases and when the Temperature decreases the equilibrium of constant increases. That means they are inversely proportional..
The numerical value of the equilibrium constant depends on the temperature (Option 1).
What is the equilibrium constant?The equilibrium constant refers to the exact value in a chemical reaction when products and reactants are found in a state of equilibrium.
A chemical reaction is a process where one or more reactants are converted into one or more products.As the temperature increases, the numerical value of this constant decreases and vice-versa.In conclusion, the numerical value of the equilibrium constant depends on the temperature (Option 1).

Why is the neutron to proton ratio so important?The ratio of neutrons to protons (n/p) is a successful way of predicting nuclear stability. This ratio is close to 1 for atoms of elements with low atomic numbers (of less than about 20 protons). The n/p ratio steadily increases as the atomic number increases past element 20 (calcium) to about element 84 (polonium).

What is the difference between a solvent molecule and a non polar solvent?
Answers
Answer:
Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out. Polar solvents have large dipole moments (aka “partial charges”); they contain bonds between atoms with very different electronegativities, such as oxygen and hydrogen. Non polar solvents contain bonds between atoms with similar electronegativities, such as carbon and hydrogen (think hydrocarbons, such as gasoline).

Answers
Taking into account the definition of ionic bond, Li loses 1 valence electron and becomes a positive ion and Cl gains 1 valence electron and becomes a negative ion.
Definition of ionic bondAn ionic bond is a type of chemical bond that occurs when one atom gives up an electron to the other, in order for both to achieve electronic stability.
This union normally occurs between metal and nonmetal elements with different electronegativity, which means that the elements have different capacity to attract electrons.
In other words, an ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.
Bond between Li and ClLi is a metal, while Cl is a nonmetal. Considering the definition of ionic bond, the Li gives up its electrons forming a cation to the Cl, which forms an anion.
In summary, Li loses 1 valence electron and becomes a positive ion and Cl gains 1 valence electron and becomes a negative ion.

A - NH3 because it’s polar
B - BR2 because it’s non polar
C - H2 because it’s polar
D - CO2 because it’s non polar
Answers
Answer:
A
Explanation:
Since water is polar, we need for there to be a polar solute. This eliminates options B and D.
Now to choose between A and C, we can look at the compounds mentioned.
For A, NH3 is mentioned, which is a polar substance.
However, for C, H2 is mentioned, which is a nonpolar molecule, contrary to what is stated by the option.
Therefore, A is the answer.

Answers
Answer:
The percent composition of barium in barium chloride is 65.9%
Explanation:
percent composition = molar weight of barium/molar weight of barium chloride x 100

and the molar weight of BaCl2 = 137.3 +( 35.5 x 2)=208.3
% composition is therefore = 137.3/208.3 x 100=65.9%
