how do you determine how many electron energy levels an element has

Answer:

See below

Explanation:

1)  Moles / volume

  .85 mole / .1 liter = 8.5 M

2)   12 moles are contained in one liter

c. The atom becomes positively charged

if the electrons are removed it means theres no longer a negative charge to balance the positive charge of the protons in the atom

Answer:

The total energy but the photons will give is 6.615 x 10^-14

Explanation:

Formula that can be used in this question is E= hf or E= hc/ λ

This is the formula that can be used to calculate the energy that the photon is carrying where it is given as the Planck's Constant .

Now putting the values given in the equation that can calculate energy we get Planck's Constant is equal to 6.62 x 10^-34

E=(6.62 x 10^-34 x 2.998 x 10^8) / ( 3 x 10^-12 )

E=6.615 x 10^-14

Answer:

The total energy but the photons will give is 6.615 x 10^-14

Explanation:

Answer:

punctuation, and if it makes sense

1. Magnitude measures the energy released by the earthquake, while intensity measures its duration. The correct option is A.

2. The conclusion you can draw between the two conditions is that there is more likely to be an earthquake in a "highest hazard" location than in a "lowest hazard" location and is denoted as option A.

3. P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.

4. Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic network.

Answer:

When an organism use chemical energy to move, some of it is lost as metabolic heat.

The term chemical energy is defined as the energy which is stored in the bonds of chemical compounds. It is given in the chemical reaction and mostly produces heat as a by-product, known as an exothermic reaction.

Energy changes as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are taken by organisms from the next level.

Thus, Metabolic heat is lost when an organism uses chemical energy to move.

...

Answer:

When an organism use chemical energy to move, some of it is lost as metabolic heat.

Answer: B, cause people need livestock and crops to survive

With such huge increases in population,there has not been a direct and equivalent increase in urban development because habitable land is already being used for livestock and crops. Therefore, option B is correct.

Infrastructure for markets, streets, solid waste, education, health, justice, and cultural heritage protection are all included in urban development. Typically, these buildings are included in sector-specific programs that also include capacity-building initiatives. Slums in big cities are also given special consideration.

The segmentation of a city into specialized functional sectors; the creation of commanding central sites for palaces, temples, and civic structures; the creation of ordered roadway systems that are rectilinear and occasionally radial;

Cities may improve social inclusion, stimulate economic growth, decouple living standards and economic growth from the use of environmental resources, conserve local and regional ecosystems, and reduce both urban and rural poverty by properly managing urban development.

Thus, option B is correct.

Why is the use of the inquiry process (or scientific method) a practical way to approach science?

1. The inquiry process is a practical way to approach science because the inquiry process begins by asking questions and moving on from there.  

2. In science it is important to investigate phenomena or certain subjects by posing questions that you would like to answer through the scientific method.

3.  Therefore, the inquiry method is connected because to inquire on a subject requires raising questions which is an essential step in scientific discovery.

Why are scientific theories modified, but seldom discarded?

1.  If a theory cannot explain new evidence or observations then the theory is revised or even thrown

out, but if the theory still explains a wide range of observations and evidence then it is revised

rather than discarded.

2.  it will still hold some value as above as you learn more you tweak your hypothesis to fit the ever expanding amount of info and data you collect and assimilate

3.  The only way they ever go away is if people stop working on them.

Explanation:

Answer:

The visible properties is you would see the salt and sugar dissolve in the water, which is called a homogeneous mixture. This mixture cannot be filtered and is transparent mostly (uniform composition).

Explanation:

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

The fossil record is considered to be incomplete because fossilization is a very rare phenomenon. Most organisms decompose quickly after their death, and their remains dispersed. In order for fossilization to occur, the remains have to be covered by sediments and stay undisturbed for thousands of years.
