Why the bonds between nonmentals tend to be covalent

1 answer:

7 0

Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.

N analyst prepared a sucrose solution by weighing 1kg of water and add 1.5kg sucrose.estimate the concentration of the resultant

makvit [3.9K]

The concentration of the solution in mass percent is 60%.

<h3>What is the mass percent?</h3>

The concentration of a substance can be expressed in mass percent. This refers to the percentage of the solute that is contained in the solution.

Thus we can write;

Mass percent = Mass of solute/ Mass of solution * 100/1

Mass percent = 1.5kg/1.5kg + 1 Kg * 100/1

Mass percent = 60%

Hence, the concentration of the solution in mass percent is 60%.

An ideal reversible heat pump is taking heat from the outside air at -14.0°c and discharging it into the house at 20.0°c. what i

just olya [345]

the coefficient of performance of this heat pump is 8.61.

The air source heat pump converts heat from the ambient air into a low-temperature liquid refrigerant. The pump compresses the liquid to raise its temperature using power. To release the heat it had been holding, it then condenses back into a liquid. Your underfloor heating system or radiators get heat.

coefficient of performance -The usable heating or cooling delivered to work (energy) needed ratio, also known as the coefficient of performance, or COP, of a heat pump, refrigerator, or air conditioning system. Higher efficiency, less energy (power) usage, and thus reduced operational costs are all related to higher COPs.

temperature of cold reservoir = -14.0°C

Tc = [ 273+ (-14.0)]K = 259K

temperature of hot reservoir = 20°C

Th = [ 273+ (20)]K = 293K

therefor, formula for coefficient of performance

Cop = Th/Th-Tc

Cop = 293/34

Cop = 8.61
