Answer:
The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds. When discussing the octet rule, we do not consider d or f electrons.
Explanation:
To answer this question Kc of this reaction OR the conc of reactants nd products at equilibria is required.
Explanation:
Answer:
When you heat ice, the individual molecules gain kinetic energy, but until the temperature reaches the melting point, they don't have energy to break the bonds that hold them in a crystal structure. They vibrate more quickly within their confines as you add heat, and the temperature of the ice goes up.
There are two types of mixture depending on the distribution of the components in the mixture. Homogeneous mixtures are mixtures which has
uniform properties all throughout the solution while heterogeneous mixtures are
the opposite they do not exhibit uniformity in any property. Example for a
homogeneous is a salt solution where at any point you get a sample the
properties are the same. For the heterogeneous mixture, a mixture of sand and
salt where at any sampling point the properties are not the same.
Answer:
In an empty 100 mL of volmetric flask add 0.4 mL of 0.500 M solution of NaCl and add add water upto the mark of 100 mL .
Explanation:
Molarity of the solution before dilution =
Volume of the solution before dilution =
Molarity of the solution after dilution =
Volume of the solution after dilution =
In an empty 100 mL of volmetric flask add 0.4 mL of 0.500 M solution of NaCl and add add water upto the mark of 100 mL .
