The pair K and Br would form an ionic bond because K is a metal and Br is a non metal.
To answer your question about which of these pairs would form an ionic bond, let's look at each pair:
1. K (Potassium) and Br (Bromine) - K is a metal and Br is a non-metal. Metals tend to lose electrons, while non-metals tend to gain electrons. This transfer of electrons results in an ionic bond. Therefore, K and Br would form an ionic bond.
2. C (Carbon) and H (Hydrogen) - Both are non-metals, so they tend to share electrons, forming a covalent bond instead of an ionic bond.
3. H (Hydrogen) and O (Oxygen) - Both are non-metals, and they also tend to share electrons, forming a covalent bond rather than an ionic bond.
4. Cu (Copper) and Cu (Copper) - Since they are the same element and both are metals, they do not form an ionic bond.
In summary, the pair K and Br would form an ionic bond.

Answer:
7.1 and 11.1
Explanation:
The symbol for the compound dinitrogen trisulfide is N2S3. It is derived from the number of nitrogen and sulfur atoms present in the compound.
The chemical compound dinitrogen trisulfide is composed of two elements: nitrogen (N) and sulfur (S). When we name the compound according to IUPAC nomenclature rules, we consider the number of each type of atom present. Dinitrogen means there are two nitrogen atoms, represented by the subscript 2, and trisulfide implies that there are three sulfur atoms, signified by the subscript 3. Hence, the symbol or chemical formula for dinitrogen trisulfide is N2S3.

Answer:
Coconut palm trees thrive in environments with temperatures above 64 degree Fahrenheit, that is tropical areas. Southern Florida is an ideal place for coconut palm trees to grow because it is tropical enough for them.
Explanation:
The right answer is physical change.
In the general sense, dissolution is the action of dissolving something, that is to say, of decomposing it by the separation of its parts.
In chemistry, dissolution is an intimate mixture of two bodies, at least one of which is liquid.
Eg: the dissolution of sugar in the water, the sugar will pass from the solid and dry state to the dissolved state so there is a physical change. The sugar is going to be surrounded by water molecules and form hydrogen bonds, so it can be a chemical change.
