Explanation:
A precipitate is defined as an insoluble substance that emerges upon mixing of two aqueous solutions.
For example,
As precipitate is a solid and it is represented by (s). And, an aqueous solution is represented by (aq).
So, the products of the given reactants will be as follows.
Hence, we can conclude that out of the given options, these two equations will produce a precipitate.
Answer:
A region of high electron density between two positively charged nuclei, such that a net attractive force results.
Explanation:
Typically, the covalent bond is rationalized on the basis of the sharing of 2 electrons between two atomic nuclei. The modern covalent bond is considered to be a region of high electron density between 2 positively charged atomic nuclei, such that internuclear repulsion is minimized, and a net attractive force results.
Ionic bonds fall outside this umbrella.
Answer:
D. Grams liquid x mol/g x delta Hfreezing
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to reason that the stoichiometry used to calculate energy released when a mass of liquid freezes, involves the grams of the liquid, the molar mass of the liquid, as given in all the group choices, and the enthalpy of freezing because that is the process whereby a liquid goes solid.
In such a way, we infer that the correct factor would be D. Grams liquid x mol/g x delta Hfreezing which sometimes is the negative of the enthalpy of fusion as they are contrary processes.
Regards!
Well where is the elements and category
