For example, salts of sodium, potassium and ammonium are usually soluble in water. Notable exceptions include ammonium hexachloroplatinate and potassium cobaltinitrite. Most nitrates and many sulfates are water-soluble
Answer:
Explanation:
Hey there!:
E = energy gained (input) - energy lost (output)
∆E = 150J - 115 J
∆E = 35 J
Hope that helps!
The change in internal energy (?E) of the system is 35 J based on the first law of thermodynamics.
This problem can be solved using the first law of thermodynamics, which states that the change in internal energy (?E) of a system is equal to the heat added to it (Q) minus the work done by it (W) - this is expressed as ?E = Q - W.
In this particular case, the system loses 115 J of heat, so Q equals -115 J (as it's lost, it's negative), and 150J work is performed on the system which equals +150 J (as work is done on it, it is positive). Therefore, substituting these values into the formula, we get: ?E = -115 J - (-150 J) = 35 J:
So, the change in internal energy of the system is 35 J.

A base is an H⁺ acceptor, whereas an acid is an H⁺ donor. Acidic chemicals are typically recognized by their sour flavor.
Any hydrogen which contains a compound capable of giving a proton to another material is described as an acid. An ion and molecule that can receive a hydrogen ion from that of an acid is known as a base. Acidic chemicals are typically recognized by their sour flavor.
In essence, an acid is a substance that has the capacity to donate an H⁺ ion plus maintain its energetic favorability even after losing an H⁺ ion. It is well known that acids may change blue litmus into red. Bases, on the other hand, have a slick consistency and a bitter flavor. A base is an H⁺ acceptor, whereas an acid is an H⁺ donor.
Therefore, a base is an H⁺ acceptor, whereas an acid is an H⁺ donor.

Covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Linear, tetrahedral and trigonal planar geometries would produce a nonpolar molecule.
Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
Using VSEPR and electron pair repulsion, we can easily find that linear, tetrahedral and trigonal planar geometries would produce a nonpolar molecule if we assume that all of the atoms attached to the central atom were identical. Any geometries which have center of symmetry will produce non polar molecule.
Therefore, linear, tetrahedral and trigonal planar geometries would produce a nonpolar molecule.
