Answer:

Explanation:

wavelength λ = 12.4 x 10⁻² m .

energy of one photon = h c / λ

= 6.6 x 10⁻³⁴ x 3 x 10⁸ /  12.4 x 10⁻²

= 1.6 x 10⁻²⁴ J .

Let density of coffee be equal to density of water .

mass of coffee = 255 x 1 = 255 g

heat required to heat up coffee = mass x specific heat x rise in temp

= 255 x 4.18 x ( 62-25 )

= 39438.3 J  .

No of photons required = heat energy required / energy of one photon

= 39438.3 / 1.6 x 10⁻²⁴

= 24649 x 10²⁴

= 24.65 x 10²⁷ .

Explanation:

One common method of separation is filtration. Filters are used everywhere. We use them in our houses to filter dust and mites out of the air we breathe. We use them to filter impurities from our water.

It is important to be able to separate mixtures to obtain a desired component from the mixture and to be able to better understand how each component works.

In chemistry and chemical engineering, a separation process is commonly used to transform a mixture of substances into two or more distinct materials. The separated products might differ in chemical properties or some physical property, such as size or crystal modification or other separation into different components.

Hopefully this helps you out.

Answer:

at the negative cathode

Explanation:

Reduction happens at the negative cathode because this is where positive ions gain electrons. Oxidation happens at the positive anode because this is where negative ions lose electrons.

Answer:

Ka = [H₃O⁺] [SO₃²⁻] / [HSO₃⁻]

Kb = [OH⁻] [H₂SO₃] / [HSO₃⁻]

Explanation:

An amphoteric substance as HSO₃⁻ is a substance that act as either an acid or a base. When acid:

HSO₃⁻(aq) + H₂O(l) ⇄ H₃O⁺(aq) + SO₃²⁻(aq)

And Ka, the acid dissociation constant is:

When base:

HSO₃⁻(aq) + H₂O(l) ⇄ OH⁻(aq) + H₂SO₃(aq)

And kb, base dissociation constant is:

Answer:

1.2 x 10²³atoms

Explanation:

Given parameters:

Mass of CO(NH₂)  = 12g

Unknown:

Number of Nitrogen atoms = ?

Solution:

Given compound;

     CO(NH₂);

  In;

         1 mole of CO(NH₂), we have 1 mole of N

let us find the number of moles of CO(NH₂);

  Number of moles  = [tex]\frac{mass}{molar mass}[/tex]

  Number of moles  = [tex]\frac{12}{60}[/tex]   = 0.2moles

Since

                  1 mole of CO(NH₂), we have 1 mole of N

                0.2 mole of CO(NH₂) will have 0.2mole of N

            1 mole of a substance contains 6.02 x 10²³ atoms

           0.2 mole of N will contain 0.2 x 6.02 x 10²³ atoms = 1.2 x 10²³atoms

Answer:

1. solid, 2.liquid, 3.gas.

Answer:

1 b. solid

2 a. liquid

3 c. gas

Answer:

The correct answer is C.

Explanation

The pH scale ranges from 0-14 so 7 is neutral.

Given :

Mass of neon gas at STP.

To Find :

The volume of 139.05 g of neon gas at STP.

Solution :

Molar mass of neon, M = 20 g.

Number of moles in 139.05 g of neon :

n = 139.05/20 ≈ 7 moles

We know, volume of 1 mole of any atom/molecules in STP is 22.4 L of volume.

So, volume of 7 moles of neon is :

V = 7×22.4 L

V = 156.8 L

Therefore, volume of 139.05 g of neon gas at STP is 156.8 L.

Explanation:

number of moles can be derived from molarity law as shown in the figure

The number of moles of sodium hydroxide are in the solution should be considered as the 0.0875 moles.

Since there is 50.0 mL of a 0.350 M sodium hydroxide solution.

So here the no of moles should be

[tex]= Molarity * volume\\\\= 250 *10^-3 * 0.350[/tex]

= 0.0875 moles

hence, The number of moles of sodium hydroxide are in the solution should be considered as the 0.0875 moles.

We are given:

Maximum concentration of Lead in water = 9 ppb

Mass of Lead in the given solution = 20 grams

Volume of water in the given solution = 250 mL

What is 1 ppb?

1 ppb, short for parts-per-billion. As from its name itself, ppb is used to find how many molecules of solute are present per 1 Billion molecules of the solvent

you can also use it in grams to get the formula:

1 ppb = 1 gram of solute / 1 Billion grams of Solvent

Finding the Ideal ppb concentration:

We are given that the maximum allowed concentration is 9 ppb

which means that we need 9 grams of the solute per 1 Billion grams of Solvent:  9 grams of Solute / 10⁹ grams of Solvent

ppb Concentration of the given solution:

We have 20 grams of Solute in 250 mL of water

Since the density of water is 1 gram/mL

20 grams of Solute / 250 grams of Solvent

As we can see, this fraction is FAR more large that the maximum ppb concentration

This means that the concentration of Lead in the Given solution is higher than the maximum amount and Hence, is unfit to drink

Answer:

C.  Cs, because it has the lower ionization energy and more easily gives up its valence electrons to participate in a reaction.

Explanation:

The Cs will produce the most hydrogen gas because it has a lower ionization energy and more easily gives up its valence electrons to participate in the reaction.

Explanation:

Answer:true

Explanation:

Covalent bonds are a class of chemical bonds where valence electrons are shared between two atoms, typically two nonmetals. The formation of a covalent bond allows the nonmetals to obey the octet rule and thus become more stable.

Answer:

covalent bonds are bonds in which valence electrons are shared.
