Answer:

synthesis

Explanation:

The reaction given is a synthesis reaction or combination reaction.

Given equation:

                        NH₃  +  HCl   →   NH₄Cl

In a synthesis reaction, a single product is formed from two or more reactants

                          A + B →  C

The formation of compounds from the union of constituent elements also falls into this category.

So the given reaction is a synthesis reaction.

In a decomposition reaction two or more products are formed from a single reactant

In a single replacement reaction, one substance replaces another.

In double replacement reactions partners in a chemical specie are exchanged.

Therefore the given reaction is a synthesis reaction

Which unit can be used to express the concentration of a solution?
exis [7]

Answer: (3) ppm

Explanation: Concentration is defined as the amount of solute dissolved in a known amount of the solvent or  a solution.

Parts per million (ppm) is used to express the concentration when a very small quantity of solute is present in a large quantity of the solution. It is defined as the mass of solute present in one milion (10^6) parts by mass of the solution.

ppm=\frac{\text {mass of Solute}}{\text {Mass of solution}}\times 10^6

L/s is used to express flow rate.

J/g is used to express energy per unit mass.

kPa is used to express pressure.

Finding energy and wavelength?
deff fn [24]
The equation is
W = C/F
W= 3.00 x 10^8 m/sec
——————————
6.165 x 10^14 Hz
W= 4.87 x 10^-7 m

Energy is
E=hF
E= (6.626 x 10^-34 Jxsec )(6.165 x 10^14 Hz)
E= 4.085 x 10^-19 J
