The true statement  for the quantum mechanical atomic model is that Electrons give off electromagnetic radiation when they jump from a high to a low energy level.

Option c is correct.

The quantum mechanical atomic model, also known as the wave mechanical model, describes the behavior of electrons in atoms as waves.

This model described that only electrons can exist only in certain discrete energy levels around the nucleus. When an electron absorbs energy, it moves to a higher energy level.

In other words, when it loses energy, it moves to a lower energy level.

Answer:

\(\frac{1000}{3}\)  

Explanation:

Given problem:

    log 9x - log 3  = 3

To solve this problem, we need to find the value of x for which when the expression is simplified, we would a solution of 3;

   From log rules;

          log a - log b  = log \(\frac{a}{b}\)  

 So;

      log 9x - log 3 = 3

      log( \(\frac{9x}{3}\))   = 3

        log 3x  = 3

 So;

            3x  = 10³

In this equation, the concentrations of the species involved in the reaction are represented by the square brackets [ ]. The subscripts indicate the stoichiometric coefficients of each species in the balanced chemical equation.

The reaction being studied involves the following species:

\(C0_4^ 2\)- (ag) + 2Ht (ag) = \(CI_20\), 2- (ag) + \(H_20\)(1)

In the equilibrium constant expression, the concentration of \(CI_20\), 2- is multiplied by the concentration of \(H_20\)(1) and divided by the product of the concentrations of \(C0_4^ 2\)- and Ht. The stoichiometric coefficients in the balanced equation are used as exponents for the concentrations of the respective species.

It is important to note that the concentrations used in the equilibrium constant expression should be in molar units (mol/L) or expressed as partial pressures for gases.

The statement is true that a molecule is composed of several functional groups.

A molecule is a group of two or more atoms held together by chemical bonds. Atoms can form chemical bonds by sharing electrons with other atoms, leading to the formation of stable molecules with unique chemical and physical properties. Molecules can be made up of atoms of the same element or different elements, and they can vary widely in size and complexity. In biology, many important molecules are made up of carbon, hydrogen, oxygen, nitrogen, and other elements, and they play critical roles in biological processes such as metabolism, cellular signaling, and genetic information storage and transmission. Examples of important biological molecules include DNA, RNA, proteins, carbohydrates, lipids, and many others. These molecules are responsible for carrying out the various functions of cells and organisms and are critical for life as we know it.

Here,

Many molecules in biology are composed of several functional groups, which are specific atoms or groups of atoms within the molecule that give it its chemical properties and reactivity. Examples of common functional groups in biological molecules include amino (-NH2), carboxyl (-COOH), hydroxyl (-OH), phosphate (-PO4), and methyl (-CH3) groups, among others. The presence of these functional groups can determine how a molecule interacts with other molecules in the cell and can influence its function and activity.

Explanation:

Answer:

Explanation:

The density of a substance can be found by using the formula

To calculate the Density in g/mL we must first convert the mass from kg to g and the volume from L to mL

For the mass

That's

1.34 kg

1kg = 1000 g

1.34 kg = 1000 × 1.34 = 1340 g

For the volume

That's

2.0 L

1 L = 1000 mL

2.0 L = 2 × 1000 = 2000 mL

So we have

mass = 1340 g

volume = 2000 mL

Substitute the values into the above formula and solve for the Density

To balance the equation and identify the type of reaction, let's start by assigning coefficients to each compound: 2H2O + 1SO3 -> 1H2SO4

To balance the equation, we need to ensure that the number of atoms on both sides is the same. Here, we have two hydrogen (H) atoms on the left side and two on the right side, so hydrogen is already balanced.

We have two oxygen (O) atoms on the left side and four on the right side, so we need to balance oxygen by adding a coefficient of 2 in front of the water molecule:

2H2O + 1SO3 -> 1H2SO4

Now the equation is balanced with two hydrogen, four oxygen, and one sulfur (S) atom on both sides.

The type of reaction represented by this equation is a combination or synthesis reaction. In a combination reaction, two or more substances combine to form a new compound. In this case, water (H2O) and sulfur trioxide (SO3) combine to form sulfuric acid (H2SO4).

From the balanced equation above,

28 g of N₂ reacted with 6 g of H₂

Therefore,

2 g of N₂ will react with = (2 × 6) / 28 = 0.43 g of H₂

We can see that only 0.43 g of H₂ is needed in the reaction.

Thus, the limiting reactant is N₂

The mass of HF produced from the given amounts of BF₃ and H₂ is 99.5 grams.

To solve this problem, we need to use stoichiometry to determine the amount of HF produced from the given amounts of BF₃ and H₂.

From the balanced equation;

2 BF₃ + 3 H₂ → 2 B + 6 HF

We can see that 2 moles of BF₃ react with 3 moles of H₂ to produce 6 moles of HF. This means that the ratio of BF₃ to HF is 2:6, or 1:3.

First, we need to calculate the number of moles of BF₃ and H₂ from their given masses and molar masses;

n(BF₃) = m(BF₃) / M(BF₃) = 40 g / 67.81 g/mol = 0.59 mol

n(H₂) = m(H₂) / M(H₂) = 5 g / 2.02 g/mol = 2.48 mol

Next, we can determine which reactant is limiting by comparing their mole ratios. The ratio of BF₃ to H₂ is 1:1.67, which means there is not enough H₂ to react with all of the BF₃. This makes H₂ the limiting reactant.

To find the number of moles of HF produced, we use the mole ratio from the balanced equation;

n(HF) = n(H₂) × (6 mol HF / 3 mol H₂) = 2.48 mol × 2

= 4.96 mol

Finally, we calculate the mass of HF produced from its number of moles and molar mass;

m(HF) = n(HF) × M(HF) = 4.96 mol × 20.01 g/mol

= 99.5 g

Therefore, the mass of HF is 99.5 grams.
