Waves that we cannot actually see (unlike ripples in water) and that DO NOT need a medium to travel through belong to which category of waves?

Answers

Answer:

electromagnetic waves

Explanation:

The waves that do not need a medium to travel through are known as electromagnetic waves.

What are electromagnetic waves?

These waves do not need any medium for their propagation or traveling. The waves have different wavelength and energy factors depending upon their rate of propagation. EMR waves travel from the sun to the earth in space.

Examples of electromagnetic waves are Xrays, gamma rays, radio waves, and more.

Five liters of air at -35°C is warmed to 89°C. What is the new volume if the pressure remains constant

Answers

Answer:

7.61 liters

Explanation:

From the question,

Applying Charles law formula,

V₁/T₁ = V₂/T₂...................... Equation 1

Where P₁ = initial volume of of air, V₂ = Final volume of air, T₁ = Initial Temperature of air, T₂ = Final Temperature of air.

make V₂ the subject of the equation

V₂ = (V₁×T₂)/T₁............... Equation 2

Given: V₁ = 5 liters, T₁ -35 °C = (-35+273) K = 238 K, T₂ = 89°C = (89+273) K = 362 K

Substitute these values into equation 2

V₂ = (5×362)238

V₂ = 1810/238

V₂ = 7.61 liters

Is Cu(OH)2 a covalent bond , an ionic bond or both?

Answers

The bond between the Cu²⁺ and OH⁻ ions is, well, ionic. However, the bond between the O and the H in the OH⁻ ion is covalent. So Cu(OH)₂ is, as a whole, an ionic compound, but it contains or comprises both ionic and covalent bonds.

The equilibrium constant for the reaction shown below is Kc=0.0091. If the equilibrium concentrations of A and B are 0.031 M and 0.0823 M, respectively, what is the equilibrium concentration of C?

Answers

Answer:

[tex][C]=0.0221M[/tex]

Explanation:

Hello there!

In this case, according to the given chemical reaction at equilibrium:

[tex]3A\rightleftharpoons 3B+2C[/tex]

It is possible for us to set up the equilibrium expression as shown below:

[tex]Kc=\frac{[B]^3[C]^2}{[A]^3}[/tex]

Whereas Kc, [A] and [B] are known as 0.0091, 0.031M and 0.0823M and it is required to calculate [C]; thus, we solve for it as follows:

[tex][C]^2=\frac{[A]^3Kc}{B]^3}[/tex]

[tex][C]=\sqrt{\frac{(0.031)^3*0.0091}{(0.0823)^3}}[/tex]

[tex][C]=0.0221M[/tex]

Answer:

2.00 M KOH

Explanation:

Divide moles by volume and make sure your volume is in LITERS, not mL.

0.0400 mol KOH / 0.0200 L = 2.00 M KOH

A sample of 0.0400 mol potassium hydroxide, KOH was dissolved in water to yield 20.0 ml of solution. The molarity of the solution is 2.00 M KOH.

How does sunlight affect seasons?

Answers

Answer:

Seasons are caused by the Earth’s revolution around the Sun, as well as the tilt of the Earth on its axis. The hemisphere receiving the most direct sunlight experiences spring and summer, while the other experiences autumn and winter. During the warmer months, the Sun is higher in the sky, stays above the horizon for longer, and its rays are more direct.

Explanation:

80 grams of water releases 2550 joules of heat. What is the temperature change of the water? Heat capacity of water is 4.2 J/g°C.

Answers

Answer:

7.59°C

Explanation:

Using the formula;

Q = m × c × ∆T

Where;

Q = amount of heat (joules)

m = mass of substance (g)

c = specific heat capacity (J/g°C)

∆T = change in temperature (°C)

According to this question;

m = 80g

c = 4.2 J/g°C.

Q = 2550J

∆T = ?

Using Q = m × c × ∆T

∆T = Q/mc

∆T = 2550 ÷ (80 × 4.2)

∆T = 2550 ÷ 336

∆T = 7.589°C

The change in temperature of water = 7.59°C.

How much water must be added to 40.0 g of CaCl2 to produce a solution that is 35.0 wt% CaCl2?

Answers

The mass of water present in the solution is 21.5 g.

What is concentration?

Concentration refers to the amount of solute in a solution. There are various ways of expressing concentration such as;

Molar concentrationMass concentrationPercentage concentration

We have the following information;

Percent concentration = 35.0 %

mass of solute = 40.0 g

Mass of water = ?

So;

35 = x/40 + x × 100/1

35 = 100x/40 + x

35(40 + x) = 100x

1400 + 35x = 100x

1400 = 100x - 35x

1400 = 65x

x = 1400/65

x = 21.5 g

Hence the mass of water is 21.5 g.

What is the molar mass of Fe2(CO3)3?

Answers

Answer:

291.7167

Explanation:

The molar mass of Fe₂(CO₃)₃ is 291.714 g/mol.

To calculate the molar mass of Fe₂(CO₃)₃, we need to consider the atomic masses of the individual elements present in the compound.

The molar mass of each element is as follows:

Fe (iron): 55.845 g/mol

C (carbon): 12.011 g/mol

O (oxygen): 15.999 g/mol

Now, let's calculate the molar mass of Fe₂(CO₃)₃:

Molar mass = (2 × atomic mass of Fe) + (3 × atomic mass of C) + (9 × atomic mass of O)

Molar mass = (2 × 55.845 g/mol) + (3 × 12.011 g/mol) + (9 × 15.999 g/mol)

Molar mass = 111.69 g/mol + 36.033 g/mol + 143.991 g/mol

Molar mass = 291.714 g/mol

Therefore, the molar mass of Fe₂(CO₃)₃ is approximately 291.714 g/mol.

In test tube 3, 3 mL of .002 M Fe(III) solution is combined with 7 mL of .02 M 5-sulfosaliclic acid (SSA) solution. What is the mole fraction of SSA in the test tube

Answers

Answer:

0.96

Explanation:

Number of moles of Fe(III) = 3/1000 *  0.002 M = 6 * 10^-6 moles

Number of moles of SSA = 7/1000 * 0.02 = 1.4 * 10^-4 moles

Total number of moles =  6 * 10^-6 moles +  1.4 * 10^-4 moles

Mole fraction of SSA = number of moles of SSA/ total number of moles.

Mole fraction of SSA =  1.4 * 10^-4 moles/  6 * 10^-6 moles +  1.4 * 10^-4 moles

Mole fraction of SSA = 0.96

Answers

Answer:

It Should  be Strong Acid

Explanation:

Strong acids and bases ionize fully in an aqueous solution. Weak acids and bases also ionize, but only partially and the reaction is reversible. So how do we know if an acid or base is strong or weak? A simple way to determine strength is to add the acid or base to water— high reactivity means a stronger acid or base. This reactivity is measured with a value called the Ka or Kb value. It tells us how reactive an acid or a base is based on how many hydronium or hydroxide ions are formed during the reaction.

Answers

Answer:

A single bond, but it's also a hydrogen bond.

Explanation:

A hydrogen bond forms when hydrogen bonds to the 3 most electronegative atoms: Oxygen, Nitrogen, or Fluorine.

It's a single bond because hydrogen only has two valence electrons. Therefore, the rest of the electrons are placed around the nitrogen atom.

Hydrogen bonding between a water molecule and an ammonia (NH3) molecule. Note that the N atom in the NH3 molecule is attracted to H atom in the H20 molecule
