Answer:

Fluorine

Explanation:

Answer:

Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.

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.

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.

[tex]\boxed {\boxed {\sf B. \ Iodine }}[/tex]

Explanation:

Atomic radius is the measurement from the nucleus to the outer edge of the electron cloud.

As you go down a group (vertically) the atomic radius increases because more electron shells are added. As you go across a period horizontally, the atomic radius decreases.  

If we look at the halogens group (17), we see they follow this order from top to bottom:

F - Fluorine

Cl - Chlorine

Br - Bromine

I - Iodine

Since it increases down the group, iodine  must have the largest atomic radius.

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.

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.

Le Châtelier's principle:

When a stress is applied to a system at equilibrium, the system will respond by shifting in the direction that opposes/ minimizes the effect of the stress.

• This stress could be the addition or removal of a product or reactant, changes in the concentration of the products or reactants, or a change in temperature.

☆ Why can heat be written on the same side of the products when the reaction is exothermic?

• Exothermic means that heat is released, thus heat can be treated as a product.

Explanation:

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.

It could lead to Fatigue

Low energy.

Headaches.

Aches, pains, and tense muscles.

Chest pain and rapid heartbeat.

Explanation:

If a construction worker consumes 18000 KJ of energy on a daily basis, this could lead to adverse effects such as fatigue, headaches, aches, tense muscles, chest pain, and rapid heartbeat.

The NHS advises a man who is working at a construction site to eat 2,500 calories, and women to eat 2,000 calories, on daily basis. On an average, construction workers such as women should have around 2,000 calories a day which carries about 8,400 kilojoules and men should have around 2,500 calories a day which is about 10,500 kilojoules.

The best diet for a construction worker include foods such as grain, vegetable, fruit, dairy product, lean meat, seed, and fats for the maintenance of a healthier condition.

If a construction worker is taking 18000 KJ of energy in diet which is almost 8000 KJ more than the required amount then in this case, the worker may have fatigue, headaches, aches, tense muscles, chest pain, and rapid heartbeat.

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.

Answer:

Explanation:

By dissolving a solute in a solvent, a solution can be formed. To dissolve the solute in the solvent quickly, the solution must be shaken well. Thus option A is correct.

A solution is a substance formed by a solid solute in a solvent. The solution can be of homogeneous or hetreogenous. A homogenous solution is the one where the solute completely dissolve in the solvent and both the solvent and solute are in one phase.

In heterogenous solution, the solute and solvent are in two different phases due to the incomplete solubility of the solute. The solubility of a solute depends on the bond type of both solvent and solute, weight of solute, temperature and pressure as well mixing mode by shaking.

Some times heating the solution can be a good way to increase the solubility and quick dissolving. Where, the solute-solute interaction decreases and solvent-solute  interaction increases.

Similarly, shaking thoroughly will make the solute easily dissolve. Hence, option A is correct.

Answer:

according to me option a is the correct one

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

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.
