The amount of heat energy absorbed when 200 grams of water are heated from 20 C to 60 C is 33,440 Joules.

To find the amount of heat energy absorbed when 200 grams of water are heated from 20 C to 60 C, we can use the equation Q = mcAT.
First, we need to find the value of m, which is the mass of the water in grams. In this case, it is given as 200 grams.
Next, we need to find the value of AT, which is the change in temperature in degrees Celsius.

This can be calculated by subtracting the initial temperature from the final temperature, which gives us 60 C - 20 C = 40 C.
The specific heat capacity of water, C, is given as 4.18 Joules per gram per degree Celsius.
Now we can plug in the values into the equation:
Q = mcAT
Q = (200 g) x (4.18 J/g°C) x (40°C)
Q = 33,440 J
Therefore, the amount of heat energy absorbed when 200 grams of water are heated from 20 C to 60 C is 33,440 Joules.

So, 5 grams of Aluminum and 10 grams of Iron pellets are heated to 100°C and added to 97.3 grams of water.

Final temperature = ?

All the heat given out by the aluminum and iron is absorbed by the water.

=> Let final Temperature be T.

For Heat Gained by Water:

T1 = 22 °C

T = ?

△T = T-22 °C

m = 0.0973 kg

c = 4200 J kg-1 °C-1

Q = 0.0973 kg * 4200 J kg-1 °C-1 * (T-22)  °C

6.02 x \(10^{20\) formula units of MgCl₂ is equal to 0.1 moles of MgCl₂.

To convert formula units of MgCl₂ to moles of MgCl₂, we need to use Avogadro's number, which relates the number of formula units to the number of moles.

Avogadro's number (NA) is approximately 6.022 x 10^23 formula units per mole.

Given that we have 6.02 x 10^20 formula units of MgCl₂, we can set up a conversion factor to convert to moles:

(6.02 x 10^20 formula units MgCl₂) * (1 mol MgCl₂ / (6.022 x 10^23 formula units MgCl₂))

The formula units of MgCl₂ cancel out, and we are left with moles of MgCl₂:

(6.02 x 10^20) * (1 mol / 6.022 x 10^23) = 0.1 mol

Therefore, 6.02 x 10^20 formula units of MgCl₂ is equal to 0.1 moles of MgCl₂.

It's important to note that this conversion assumes that each formula unit of MgCl₂ represents one mole of MgCl₂. This is based on the stoichiometry of the compound, where there is one mole of MgCl₂ for every one formula unit.

Additionally, this conversion is valid for any substance, not just MgCl₂, as long as you know the value of Avogadro's number and the number of formula units or particles you have.

Option D, W3+ (g) → W4+ (g) + e-, requires the most energy for the ionization process.

The ionization interaction that requires the most energy is choice D, where W3+ (g) is ionized to W4+ (g) by the deficiency of one electron. This is on the grounds that the energy expected to eliminate an electron from a particle increments as the particle turns out to be all the more decidedly charged. Hence, it takes more energy to eliminate an electron from W3+ (g) than it does from W+(g), W2+ (g), or W3+ (g).

Choice An includes the expulsion of one electron from an impartial tungsten iota, and choice B includes eliminating an electron from W+. Choice C includes eliminating an electron from W2+. These ionization processes require less energy than choice D in light of the fact that the ionization energy increments as the particle turns out to be all the more emphatically charged. Hence, the ionization energy expected to eliminate an electron from W3+ is more prominent than that expected to eliminate an electron from any of the past particles.

Subsequently, choice D, W3+ (g) → W4+ (g) + e-, requires the most energy for the ionization interaction.

Two non-renewable resources are coal and petroleum. A natural resource that cannot be easily replaced by natural means quickly enough to keep up with use is referred to as a non-renewable resource (also known as a finite resource).

A natural resource that cannot be easily replaced by natural means quickly enough to keep up with use is referred to as a non-renewable resource (also known as a finite resource). Fossil fuels made of carbon are one instance. With the use of heat and pressure, the original biological matter transforms into a fuel like petrol or oil. Although individual elements are always conserved, earth minerals and metal ores, fossil fuels (coal, petroleum, and natural gas), and groundwater in some aquifers are all regarded as non-renewable resources (except in nuclear reactions, nuclear decay or atmospheric escape). Coal, crude oil, and natural gas are examples of natural resources that take thousands of years to naturally produce and cannot be replaced as quickly as they are used up.

The remains of animals that have been submerged for millions of years deep within the earth's crust give rise to petroleum.

These species, which include different kinds of plants and animals, progressively dissolved over time.

These remnants turned into petroleum as a result of the intense heat, pressure, and lack of air.

Although petroleum is manufactured over millions of years, we also use it at a faster rate than it is created.

The equilibrium constant (Kc) for the given reaction is approximately 16.448. The value of Kc indicates the relative concentrations of reactants and products at equilibrium. In this case, a Kc greater than 1 suggests that the products (H2 and P4) are favored at equilibrium, indicating that the forward reaction is more favorable.

To determine the equilibrium constant (Kc) for the given reaction:

4PH3(g) ↔ 6H2(g) + P4(g)

We can write the equilibrium constant expression based on the stoichiometric coefficients:

Kc = ([H2]^6 * [P4]) / ([PH3]^4)

Substituting the given equilibrium concentrations:

[PH3] = 0.250 M

[H2] = 0.580 M

[P4] = 0.750 M

We can plug in these values into the equilibrium constant expression:

Kc = ([0.580]^6 * [0.750]) / ([0.250]^4)

Kc = (0.0860128 * 0.750) / (0.00390625)

M=molar mass .

n( sulfur ) =64

32

= 2

using N =nL

where N is number of entities

n = moles

L= 6.02×20^23

N( of atoms of sulfur) =2(6.02×10^23)

32(6.02 x 10²³) number of atoms are in 64 g sulfur (S) is:

C. 32(6.02 x 10²³) atoms

To determine the number of atoms in 64 grams of sulfur (S), you need to use Avogadro's number, which is approximately 6.02 x 10²³ atoms/mol. This number represents the number of atoms or molecules in one mole of a substance.

1. Find the molar mass of sulfur (S):

The molar mass of sulfur (S) is the mass of one mole of sulfur atoms, and you can find it on the periodic table. The molar mass of sulfur is approximately 32.06 g/mol.

2. Calculate the number of moles of sulfur:

To calculate the number of moles, divide the given mass (64 g) by the molar mass of sulfur (32.06 g/mol):

Number of moles = Mass of sulfur / Molar mass of sulfur

Number of moles = 64 g / 32.06 g/mol

Number of moles = 1.997 moles

3. Use Avogadro's number to find the number of atoms:

Now, multiply the number of moles by Avogadro's number:

Number of atoms = Number of moles × Avogadro's number

Number of atoms = 1.997 moles × 6.02 x 10²³ atoms/mol

Number of atoms = 1.202 x 10²⁴ atoms

So, there are approximately 1.202 x 10²⁴ atoms in 64 grams of sulfur (S). The closest option to this value is:
