Answer:

Lens

A curved piece of glass or other transparent material that is used to refract light.

Explanation:

u got ig?

A curved piece of glass or other transparent material that is used to refract light is called a lens. The correct option is B).

What are lenses?

A curved piece of transparent material, such as glass, that bends light is called a lens. A lens's shape and the object's position both affect the kind of image it produces.

The center of a concave lens is thinner than the edges. Bent glass is defined as glass that has been curved or bent into a convex or concave shape. The desired shape is created by gently heating the glass until it becomes pliable, then molding it into that shape.

Light is refracted through lenses. When a light beam enters a lens, it is refracted; then, when it leaves the lens, it is refracted once more.

Therefore, the correct option is the B) lens.

How many Liters are in 17.3 moles of Iron?

Answers

Answer:

There are 0.12269 Liters of Iron

Explanation:

First, by means of the molecular weight equation, the grams of iron corresponding to 17.3 moles can be calculated:

[tex]MW=\frac{mass(grams)}{moles}[/tex]

[tex]mass=MW*moles=55.845\frac{g}{mol} *17.3mol=966.119 g[/tex]

Then using the density equation the iron milliters are calculated:

[tex]d=\frac{mass(g)}{volume(mL)}[/tex]

[tex]volume=\frac{mass}{density}=\frac{966.119g}{7.874\frac{g}{mL} } =122.69 mL[/tex]

Milliliters to liters are converted:

122.69 mL = 0.12269 L of Iron.

Answer:

[tex]V_{Fe}=0.125L[/tex]

Explanation:

Hello,

In this case, given the moles of iron, we need to use it atomic mass (55.845  g/mol) and density (7.874 g/cm³) in order to firstly convert from moles to grams and secondly from grams to cubic centimetres:

[tex]V_{Fe}=17.6molFe\times \frac{55.845gFe}{1molFe}*\frac{1cm^3}{7.874gFe}=124.8cm^3[/tex]

Finally, we obtain the volume in litres by:

[tex]V_{Fe}=124.8cm^3*\frac{1L}{1000cm^3} \\\\V_{Fe}=0.125L[/tex]

Best regards.

c
They have relatviely higher melting and boiling points.

d
Many of these compounds are usallly liquids or gases at room temperature.

Answers

Answer:

D. They are usually liquids or gases at room temperature.

Explanation:

Covalent compounds have covalent bonds, meaning that they share electrons between elements and have relatively higher melting melting and boiling points due to the strength of their bonds. However covalent bonds are weaker than ionic bonds which is why B is correct. D is the only incorrect one because it is incorrect and contradicts point C. If a substance has a high melting/boiling point than it is much more likely to be solid at room temperature because of the high temperature it needs to pass in order to be a liquid or gas.

What is the volume of solution (in mL) produced when 91.80g of Mg(OH)2 are used
to produce a 0.7M solution? Record your answer to 1 decimal places.

Answers

Answer:  The volume of solution is 2248 ml

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

[tex]Molarity=\frac{n\times 1000}{V_s}[/tex]

where,

n = moles of solute

[tex]V_s[/tex] = volume of solution in ml

moles of [tex]Mg(OH)_2[/tex] = [tex]\frac{\text {given mass}}{\text {Molar mass}}=\frac{91.80g}{58.32g/mol}=1.574mol[/tex]

Now put all the given values in the formula of molality, we get

[tex]0.7=\frac{1.574\times 1000}{V_s}[/tex]

[tex]V_s=\frac{1.574\times 1000}{0.7}=2248ml[/tex]

Therefore, the volume of solution is 2248 ml

What process in stars played a role in the formation of the universe?

Answers

Answer:

When a clump of interstellar gas and dust is small and dense enough, gravity plays a decisive role in turning that material into a new star.

Explanation:

The process in stars that leads to the formation of the universe has been fusion and gravitational force.

The stars are hot massive clumps of gases. dust and clouds. The formation of stars with the fusion of mass has been given by the density stabilization for the gases and results in stars.

In space, the force acting has been the gravitational force. The higher the mass of the object stronger has been the force that results in the formation of galaxies and the universe.

The stars with the increase in the mass from the fusion of dust and clouds result in increased gravitational force and thereby the formation of planets and other bodies.

Thus, the process in stars that leads to the formation of the universe has been fusion and gravitational force.

Answers

Answer:

Explanation:

When a nuclide is bombarded with alpha particles, we notice an increase in its mass and charge since an alpha particle has a mass of four and a charge of +2. recall that nuclear equations must be balanced. That is, the masses and charges on the left hand six and the right hand side of the nuclear reaction equation must be exactly the same.

Looking at the nuclear reaction at hand, the total mass on the left hand side has to be 246 while the total charge on the left hand side of the equation will be 98. Coming over to the right hand side, the total masses are also found to be the same as a neutron with no charge and a mass of 1 is produced. Hence the nuclear reaction equation is balanced when an alpha particle (helium nucleus) is substituted for X in the equation.

how does the Doppler effect related to the universal expanding?

Answers

The Doppler effect doesn't just apply to sound. It works with all types of waves, which includes light. Edwin Hubble used the Doppler effect to determine that the universe is expanding. Hubble found that the light from distant galaxies was shifted toward lower frequencies, to the red end of the spectrum. This is known as a red Doppler shift, or a red-shift. If the galaxies were moving toward Hubble, the light would have been blue-shifted.

It is the most common long-term disease of children. It causes repeated episodes of wheezing, breathlessness, chest tightness, and nighttime or early morning coughing.2 We know that family history contributes to susceptibility, but in most cases we dont know what causes asthma to develop, and we dont know how to cure asthma. You can control your asthma by knowing the warning signs of an attack, avoiding things that trigger an attack, and following the advice of your doctor.Effects of Asthma3 In 2001, 20.3 million Americans had asthma, and 12 million had had an asthma attack in the previous year. If a person has a parent with asthma, he or she is three to six times more likely to develop asthma than is a person who does not have a parent with asthma.How Asthma Is Diagnosed4 Asthma can be difficult to diagnose, especially in children under 5 years old. Regular physical exams that include checks of lung function and for allergies can help make the right diagnosis.5 A health-care provider trying to diagnose asthma will ask you questions about coughing, especially coughing at night, and whether breathing problems are worse after physical activity or during a particular time of year. Providers also ask about other symptoms, such as chest tightness, wheezing, and colds that last more than 10 days.6 Also, a provider will ask about your family history of asthma, allergy and other breathing problems, and your home environment. He or she also will ask about lost school or work days and limits on your activity.7 Testing of lung function, called spirometry, is another way to diagnose asthma. A spirometer is a piece of equipment that measures the largest amount of air you can exhale after taking a very deep breath. Airflow can be measured before and after you use an asthma medication.What An Asthma Attack Is8 Airways are the paths that carry air to the lungs. As the air moves through the lungs, the airways become smaller, like branches of a tree. During an attack, the sides of the airways in your lungs become inflamed and swollen. Muscles around the airways tighten, and less air passes in and out of the lungs. Excess mucus forms in the airways, clogging them even more. The attack, also called an episode, can include coughing, chest tightness, wheezing, and trouble breathing.Causes Of An Asthma Attack9Environmental exposures, such as house dust mites and environmental tobacco smoke, are important triggers of an attack. Some of these triggers are listed in the box below.How Asthma Is Treated10 You can control your asthma and avoid an attack by taking your medicine as prescribed and avoiding the triggers that can cause an attack. Its just as important that you remove the triggers in your environment that you know make your asthma worse.11 Medicine for asthma is different for each person. It can be inhaled or taken as a pill and comes in two typesquick-relief and long-term control. Quick-relief medicines control the symptoms of an asthma attack. If you are using your quick-relief medicines more and more you should visit your health-care provider to change your asthma management plan. Long-term control medicines make you have fewer and milder attacks, but they dont help you if youre having an attack.Important Asthma Triggers:Dust Mites12 Mattress covers and pillow case covers provide a barrier between house dust mites and the person with asthma. Down-filled pillows, quilts, or comforters should not be used and stuffed animals and clutter should be removed from bedrooms.Pets13 Furry pets may trigger an attack. The simplest solution to this situation is to find another home for the pet. However, some pet owners may be too attached to their pets or unable to locate a safe new home for the animal. Any animal causing an allergic reaction should not be allowed in the bedroom. Pets should be kept outside as much as possible and bathed weekly. People with asthma are not allergic to their pets fur,so trimming the pets fur will not help your asthma. Frequent vacuuming will reduce the presence of the allergen. If the room has a hard surface floor, it should be damp mopped weekly.Mold14 When mold is inhaled, it can cause asthma attacks. Eliminating mold throughout the home can help control asthma attacks. Keep humidity levels between 35% and 50%. In hot, humid climates, this may require the use of air conditioning and/or dehumidifiers. Fixing water leaks and cleaning up any mold in the home can also help.By defining unfamiliar terms such as spirometry, spirometer, and episode, the writer makes this passageA)more convincing.B)more complicated.C)easier to understand.D)more interesting to a doctor.
