The period of time needed for a radioisotope to lose one-half of its activity is known as that isotopes

Answers

Explanation:

The radioactive scattering technique is called radioactive degradation. For each radioactive isotope, the natural radioactive cycle is special and is determined by a period of time termed a half-life. One half-life was its time needed to experience radioactivity for half of both the radioactive nuclei.

If two vectors combine in the same direction what mathematical operation would you use to
find the resultant vector?

Answers

Answer:

The head-to-tail rule is used to sum two vectors pointing in the same direction. (Vectors in the same direction are called collinear). The sum vector is slightly moved out of its correct position so that you can see it. For now, to determine if two vectors have the same direction look at a picture or use geometry.

How many particles are present in a 56.9 mole sample of calcium hydroxide?

Answers

Answer:

Particles?  Calcium hydroxide does not exist as discrete molecules, but as a network solid.  The only way you would have separate particles, is if the calcium hydroxide was dissolved in a boatload of water.  Ca(OH)2 is not all that soluble in water.  Nonetheless, assume a lot of water, enough to dissolve 56.9 moles.

Ca(OH)2 --> Ca2+ + 2OH-

56.9 moles Ca(OH)3 x (3 moles ions / 1 mol Ca(OH)2) = 170.7 mol ions

How does a flux capacitor deteriorate under high octane pressure?

Answers

The high octane pressure interferes with the neutrino conjugations, which in turn decrease the fusion potential to below optimal levels. If this is allowed to continue, the the sub-optimal fusion potential will degrade the bucking electrodes and final flux concentration vortex. At that point the flux capacitor will deteriorate quickly and will likely not be repairable.

If a disease strikes the snake population in the food chain shown, what will happen to the populations of hawks?

The population of hawks would decrease
The population of hawks would increase
The population of hawks would stay the same.
The population of hawks will increase and then decrease.

Answers

Answer:

The population of hawks would decrease cause the snake is decreasing

Explanation:

although i would think hawks could eat rabbits but it doesn't ask you that so its haws decreasing

Answer: The population of Hawks will decrease.

Explanation:  When the population of one species decreases suddenly, as when a disease strikes the population, the populations higher in the food chain also decrease due to a loss in food supply. In this case the hawk population decreases because there are suddenly fewer snakes to eat. The species below the diseased species in the food chain increase because there are fewer predators. In this case, the rabbit population increases because there are fewer snakes to eat them.

Most representative metal atoms tend to gain enough electrons to attain a stable noble gas (octet) configuration.

True or False

Answers

Answer:

False

Explanation:

Non- metals tend to gain electrons easily, metals tend to lose electrons easily

For example, oxygen, a non-gas, when it is an ion, has the option to lose 6 electrons to become like helium, or gain 2 electrons to become like the noble gas neon. However, it becomes like neon for 2 reasons.

A. As a general rule, atoms lose/gain the LEAST amount of electrons.

B. Oxygen is a nonmetal, therefore, to become like a Noble Gas, it would gain, as non-metals usually would, 2 electrons.

What is the molarity of a solution if 0.529 moles of LiCl is dissolved in 687 mL of water?

Answers

Answer:

Molarity of solution = 0.77 (Approx.)

Explanation:

Given:

Moles of LiCl = 0.529

Volume of water  = 687

Find:

Molarity of solution

Computation:

Molarity of solution = [Moles/Volume]1000

Molarity of solution = [0.529/687]1000

Molarity of solution = 0.77 (Approx.)

An electron in an atom of hydrogen goes from energy level 6 to energy level 2. What is the wavelength of the electromagnetic radiation emitted?

Answers

Answer:

410 nm

Explanation:

when an electron falls from ni=6 to nf=2 , a photon of wavelength 410 nm is emitted.

When an electron falls then the wavelength of the electromagnetic radiation emitted is = 410 nm.

What is electromagnetic wavelength?

When The Electromagnetic wavelength directs to the measured distance between the trough or crest of each adjacent wave generated by the electromagnetic disturbance.

When the wavelength of electromagnetic radiation is comparable to the de Broglie wavelength of its quantum (photon).

Now we are Showing that the wavelength of electromagnetic radiation is comparable to the de Broglie wavelength of its quantum (photon).

Therefore, when an electron falls from ni=6 to nf=2, a photon of wavelength 410 nm is emitted.

4. Which chemical formula below contains 2
different elements?
A. CO
B. Fe2O3
C. C2H4
D. All of the above

Answers

All of the formulas have two elements formula one has Carbon and Oxygen, Formula two has Iron and Oxygen, formula three has Carbon and Hydrogen.

The chemical formula of CO, Fe₂O₃, and C₂H₄ contain atoms of two different elements. Therefore, option (D) is correct.

What is the chemical formula?

A chemical formula provides information about the chemical proportions of atoms of each element that are present in a molecule or chemical compound. The chemical formula can be represented by using chemical symbols of elements, numbers (subscripts), and other symbols, such as commas, dashes, brackets, and plus (+) and minus (−) signs.

A chemical formula of a compound has no words but can be written in certain simple chemical structures. Chemical formulae can be more limited in power than chemical names and structural formulae. There are two kinds of chemical formulas in which one empirical formula and another molecular formula.

In the chemical formula of carbon monoxide (CO) has carbon and oxygen two different elements. In the chemical formula of iron oxide (Fe₂O₃)  iron and oxygen are two different elements. In the chemical formula of ethane (C₂H₄ ) has carbon and hydrogen two different elements.

1. Sequence Order the path of a sound wave
from when it is produced by a source until
it is interpreted by the brain

Answers

Answer:1. The sound waves arrive at the pinna (auricle), the only visible part of the ear.

2. Once the sound waves have passed the pinna, they move into the auditory canal (external

acoustic meatus) before hitting the tympanic membrane (eardrum).

3. Once the sound waves reach the tympanic membrane, it begins to vibrate and they enter

into the middle ear.

4. The vibrations are transmitted further into the ear via three bones (ossicles): malleus

(hammer), incus (anvil), and the stapes (stirrup). These three bones form a bridge from

the tympanic membrane to the oval window.

5. Once sound passes through the oval window, it enters into the cochlea in the inner ear.

6. Hair cells in the organ of Corti (within the cochlea) are stimulated which in turn

stimulates the cochlear branch of the vestibulocochlear nerve.

7. The cochlear nerve then transmits electrical impulses to the auditory region of the brain

in the temporal lobe.
