filtration is the answer

Explanation:

Answer:

Distance also affects the apparent brightness of an object. A distant, but very energetic star can appear dimmer to us than a lower-energy, but closer one. ... Each of their effective temperatures results in a different brightness for the object. The quasar, however, is very far away, and so appears dim.

Answer:

Alkali metals

Explanation:

The lowest number of valence electrons is found in the alkali metals (group 1), which have only one valence electron per atom.

Answer:

Alkali metals:) im 100% sure because i just got done learning everything in the periodic table:)

Explanation:

Answer:

A

Explanation:

This is because in the graph shown line A has a quite greater impact of refraction than line B .

Hence, we can conclude that line A has the greater reaction at a faster rate.

Answer:

C. Copper used for making electrical wires

Explanation:

When a coating of a particular metal is applied on another metal, the process is termed as electroplating. The process is carried by the process of electro-deposition. This process is carried on in order to enhance the quality of the objects manufactured. The coating helps in resistance and provides an attractive appearance to the object.  

Option C. is not an example of electrocoating because on the copper wires no other metal coating is done. In all the other three options, coating has been done on the object.

Answer: [tex]K_p=\frac{1}{[p_{Cl_2}]^6}[/tex]

Explanation:

Equilibrium constant is defined as the ratio of pressure of products to the pressuure of reactants each raised to the power their stoichiometric ratios. It is expressed as [tex]K_p[/tex]  

For the given chemical reaction:

[tex]P_4(s)+6Cl_2(g)\rightarrow 4PCl_3(l)[/tex]

The expression for [tex]K_p[/tex] in terms of gaseous is written as:

[tex]K_p=\frac{1}{[p_{Cl_2}]^6}[/tex]

Answer:

A. 0.48mol O2

Explanation:

The balanced equation is given as follows:

2CH3OH + 3O2 → 2CO2 + 4H2O

This shows that 2moles of CH3OH is required to react with 3 moles of O2

If 0.32 moles of CH3OH are reacted, then;

0.32 × 3/2 moles of O2 is required

= 0.96/2

= 0.48mol of O2

Answer:

Point of incidence: The point on the surface where the incident ray strikes the surface is called the point of incidence. Reflected ray: The ray of light that bounces back from the surface of an object is called a reflected ray of light.

Answer:

4383.28 g

Explanation:

First we'll need to convert molecules into moles, we can do so using Avogadro's number:

Then we will convert 99.62 moles of carbon dioxide (CO₂) into grams, using its molar mass:

Answer:

[tex]2Al(s) + 3NiSO4 --> Al2(SO4)3 + 3Ni[/tex]

Explanation:

This reaction type is a single replacement. The format of a single replacement is:

[tex]A+BC --> B+AC[/tex]

A= Al

B= Ni

C= SO

The coefficient 3 for Ni would become a subscript for  AC. After you plug those into the reaction you need to count how many of each are on the left side and try to get the same number on the right side. Both sides must be equal to have a balanced equation.

AnswerB:

Explanation:

Heat can travel from one place to another in different ways. The different methods of heat transfer are conduction, convection and radiation. Here heat transfers from the glass to the ice through conduction.

The process of transmission of energy from one particle of the medium to another with the particles being in direct contact with each other is defined as the conduction. It is also known as the thermal conduction or heat conduction.

In conduction an area of higher kinetic energy transfers thermal energy towards the lower kinetic energy area. Here a transfer of heat energy occurs from tea molecules to the ice cube. Due to the transfer of heat melting of ice occurs.

As the ice melts, the tea starts cooling while heating the ice cube. So the ice cools down the tea. The tea will be melted by the ice here.

Answer:(4) pH 3 to 1

Explanation:

im 95% sure its the right answer

Answer: 3

Explanation: 5 times a number would be 5x, then increase that by 4 is 5x+4.  The problem then says 5x + 4 ≥ 19.  If we solve for x then we get x ≥ 3 so x has to be greater than or equal to 3, so the smallest number it could be is 3.  You can even try any number smaller than 3 and see it doesn't work.  even something like 2.9

Answer:

As the axial tilt increases, then the seasonal contrast increases so that winters are colder and summers are warmer in both hemispheres. The northern hemisphere is tipped away from the Sun, producing short days and a low sun angle. What kind of effect does the earth's tilt and subsequent seasons have on our length of daylight (defined as sunrise to sunset). Over the equator, the answer is not much.

Answer:

2Na+Cl2 -> 2NaCl

Explanation:

1Na+1Cl 2 -> 1NaCl (i'm assuming they want you to balance it so ill start with 1)

Na = 1

Cl = 2 (it is 2 because it is Cl2, meaning that there are 2; but remember that you cannot change this number only coefficients)

Na = 1

Cl = 1

We need to have 2 Cl on the product side

1Na+1Cl 2 -> 2NaCl

Now we need 2 Na on the reactants side

The final equation is

2Na+Cl2 -> 2NaCl

Now it is balanced

Na = 2

Cl = 2

--

Na = 2

Cl = 2
