A thermoacoustic generator transforms thermal energy into electrical energy. Thermal energy is transferred to a gas by a heat ex

changer. The thermal energy causes the gas particles to vibrate rapidly and generate a sound wave. These vibrating gas particles are then used by an alternator to generate electrical energy. The gas used in this kind of generator must be nonreactive to avoid the danger of fire. Using heavier gases increases the amount of electrical energy generated.
Which two elements on the table are most likely to be good choices for use as the gas in a thermoacoustic generator?

Here are options


A. bromine


B. krypton


C. iodine


D. xenon


E. astatine


F. radon

All rocks follow the same pathway though the rock cycle us a false statement. Why?
sammy [17]

False.

This is because there are three different rocks, metamorphic, sedimentary, and igneous. Thus, meaning that there are three different pathways, making this statement false.

Hope this helps!

Which of the following is not equal to 0.1 centimeters?
Anon25 [30]

Answer:

c) 10 millimeters (mm)

Explanation:

The unit conversions are as follows:

1 cm = 10 mm (millimeter)

1 cm = 0.01 m (meter)

1 cm = 0.00001 km (kilometer)

1 cm = 10000 μm (micrometer)

Based on the above conversions:

0.1 cm = \frac{10 mm*0.1 cm}{1 cm} = 0.1 mm

0.1 cm = \frac{0.01 m*0.1 cm}{1 cm} = 0.001 m

0.1 cm = \frac{0.00001 km * 0.1 cm}{1 cm} = 0.000001 km

0.1 cm = \frac{10000 um*0.1cm}{1 cm} =1000 um

Therefore, 0.1 cm = 10 mm is incorrect instead it is 0.1 mm

Define: Atomic Mass, Mass Number, Isotope
Westkost [7]

Answer:

Explanation:

the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.

the total number of protons and neutrons in a nucleus.

to write the symbol for an isotope, place the atomic number as a subscript and the mass number (protons plus neutrons) as a superscript to the left of the atomic symbol

Describe the orbital notation and electron configuration notation to describe the placement of all of the electrons in an atom o
andriy [413]
The arrangement of the electrons on the orbitals is governed by the principles of quantum energy. To be able to draw the correct electronic configuration of an element, they should follow these three principles.

1. Aufbau's Principle. The electrons of an element should be filled up from the highest energy level. You can use the periodic table as a guide for this. In decreasing order, the energy of the orbitals are 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d and 7p. Each 'box' of these orbital must be filled with two electrons from 1s before moving on to the next.

2. Hund's rule. This states that you must fill all boxes of one orbital with one electron first. For example, 2p has 3 boxes. You fill one electron for each box first before going back to fill it to two electrons if there are still excess.

3. Pauli's Exclusion Principle. This states that no electrons of the same element should have the same quantum numbers. To achieve this, the two electrons in each box should have opposite spins, one facing up, and the other facing down.

Using these three rules, you will be able to draw the electronic configuration of Fluorine with 9 electrons as shown in the picture.
