Answer:
Like your refrigerator, heat pumps use electricity to move heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. ... The most common type of heat pump is the air-source heat pump, which transfers heat between your house and the outside air.
Explanation:
The aufbau principle, from the German Aufbauprinzip (building-up principle), also called the aufbau rule, states that in the ground state of an atom or ion, electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels.
In the herbicide linuron whose structure is shown in the image attached, there are four pi bonds.
A pi bond is formed by a sideways overlap of atomic orbitals. A sigma bond is formed by an end to end or head to head overlap of atomic orbitals. Pi bonds lead to the occurrence of multiple bonds in the molecule.
In the herbicide linuron whose structure is shown in the image attached to this answer, there are four pi bonds which are easily spotted as double bonds in the structure.

Answer: 7.90 g/cm^3
Explanation:
Density = Mass / Volume
The first step is to find the volume by multiplying the three measures of the cube that have been provided.
3.50 x 0.755 x 2.25 = 5.95 cm^3
Now we can plug the numbers into our equation.
Density = 47.0g / 5.95 cm^3
Density = 7.90 g/cm^3
