The empirical formula of the solid can be represented as x:y.

The empirical formula of the solid is determined by the ratio of the atoms found at the corners and faces of the face-centered cubic cell.

Since the number of atoms at the corners is represented by x, and the number of atoms at the faces is represented by y, then the empirical formula of the solid can be represented as x:y.

For example, if a face-centered cubic cell contains 2 atoms at the corners and 6 atoms at the faces, then the empirical formula of the solid can be written as 2:6, or 1:3.

The empirical formula of the solid, it is necessary to first determine the total number of atoms that make up the cell.

This can be done by multiplying the number of atoms at the corners (x) by 8, since there are 8 corners in a face-centered cubic cell, and adding the result to the number of atoms at the faces (y).

This total number of atoms can be represented as T, and can be written as T = 8x + y.

The empirical formula of the solid is then determined by dividing the number of atoms at the corners (x) and faces (y) by the total number of atoms (T). This calculation can be written as x/T and y/T.

Therefore, the empirical formula of the solid is determined by the equation x/T:y/T.

For example, if a face-centered cubic cell contains 2 atoms at the corners and 6 atoms at the faces, then the total number of atoms in the cell is 14 (8x2 + 6).

Therefore, the empirical formula of the solid can be calculated as 2/14:6/14, or 1:3.

The empirical formula of the solid in a face-centered cubic cell can be determined by,

calculating the total number of atoms in the cell (8x + y), and then dividing the number of atoms at the corners (x) and faces (y) by this total number. The result is the empirical formula of the solid, which is represented as x:y.

If 150cm³ of carbon(11) oxide burns in 80cm³of oxygen according to the given equation the volume of oxygen that was in excess is 5.6 cm³.

From the balanced equation, we can see that 2 moles of CO react with 1 mole of O2. Therefore, we need to determine how much O2 is required to react with 150 cm³ of CO.

Let's start by calculating the number of moles of CO:

n(CO) = V(CO) / molar volume at STP

= 150 cm³ / 22.4 L/mol

= 0.006696 mol

Since the stoichiometric ratio of equation of CO to O2 is 2:1, we need half as many moles of O2 as CO. Therefore, the number of moles of O2 required is:

n(O2) = 1/2 * n(CO)

= 1/2 * 0.006696 mol

= 0.003348 mol

Now we can calculate the volume of oxygen required using the ideal gas law:

PV = nRT

Assuming the temperature and pressure are constant, we can simplify this to:

V = n(RT/P)

where V is the volume of gas in liters, n is the number of moles of gas, R is the ideal gas constant, T is the temperature in Kelvin, and P is the pressure in atmospheres.

At STP, the temperature is 273 K and the pressure is 1 atm. Therefore:

V(O2) = n(O2)(RT/P)

= 0.003348 mol * (0.0821 L·atm/mol·K * 273 K / 1 atm)

= 0.0744 L

= 74.4 cm³

So the volume of oxygen required to react with 150 cm³ of CO is 74.4 cm³. Since the initial volume of O2 was 80 cm³, the volume of O2 in excess is:

V(excess) = V(initial) - V(required)

= 80 cm³ - 74.4 cm³

= 5.6 cm³

Therefore, the volume of oxygen that was in excess is 5.6 cm³.

The empirical formula represents the simplest whole-number ratio of atoms in a compound. In order to determine the empirical formula, we must first determine the number of moles of each element present in the compound.

Then, we must divide each of these values by the smallest value obtained. This will give us the ratio of the elements, which will allow us to write the empirical formula of the compound.
Given data:
Mass of compound = 180.00 g
Mass of sodium (Na) = 30.06 g
Mass of chromium (Cr) = 72.50 g
Mass of oxygen (O) = 77.44 g


The ratio of Na:Cr:O is therefore 1:1.067:3.707. However, empirical formulas should be in the simplest whole number ratio. Therefore, we will multiply all values by the smallest whole number that will give us a whole number ratio.

Statement 3: When substances are mixed together, the mixture assumes the physical properties of each individual substance.

Mixtures are compounds that are made up of two or more chemical compounds which are not linked to each other chemically. They can be easily separated as there are no chemical reaction between each other.

Mixtures are compounds that retain their respective physical properties even though they were mixed together as there are no reaction between the two. Thus, these physical properties can be used to separate mixtures. Example: Oil in water. They have different densities. Thus, oil will float on water. We can exploit this physical property and separate them using separating funnel.

The shape of a molecule based on the number of electron pairs on the valence shell of its central atom

Explanation:

The improvement of the Sidgwick-Powell theory came to be known as the Valence Shell Electron Pair Repulsion theory (VSEPR). This theory approaches the determination of molecular shape from the perspective of the number of electron pairs on the valence shell of the central atom in the molecule.

Electron pairs on the valence shells of atoms leads to repulsion. Repulsion between two lone pairs is greater than repulsion between a lone pair and a bond pair which is also greater than repulsion between two bond pairs.

Lone pairs cause more repulsion, hence they distort molecules from the ideal shape predicted based on their electron domain geometry.
