Answer:

the answer is A: 7.0 ppm

Explanation:

To calculate the dissolved oxygen concentration in parts per million (ppm), we need to divide the mass of the dissolved oxygen (0.0070 g) by the mass of the water solution (1000 g) and then multiply by 10^6 to convert the result to ppm.

0.0070 g / 1000 g * 10^6 = 7.0 ppm

The dissolved oxygen concentration in parts per million (ppm)  for 0.0070 gram of oxygen in 1000 g of water is 7 ppm. Hence, option A is correct.

Dissolved oxygen (DO) refers to the amount of molecular oxygen (O2) dissolved in water or another liquid. It is an important measure of water quality, as many aquatic organisms depend on dissolved oxygen to survive.

Dissolved oxygen concentration (ppm) = (mass of dissolved oxygen / mass of solution) x 10^6

The mass of the solution is the mass of the water plus the mass of the dissolved oxygen:

mass of solution = 1000. grams of water + 0.0070 gram of oxygen

mass of solution = 1000.0070 grams

Substituting the values in the formula, we get:

Dissolved oxygen concentration (ppm) = (0.0070 / 1000.0070) x 10^6

Dissolved oxygen concentration (ppm) ≈ 6.9997 ppm

Therefore, the dissolved oxygen concentration of this solution in parts per million is approximately 7.0 ppm (option A).

The size and mass of an atom are determined by the number of protons, neutrons, and electrons it contains and can increase or reduce size & mass.

Protons and neutrons are the subatomic particles responsible for most of the mass of an atom. Protons have a mass of approximately 1 atomic mass unit (amu), while neutrons have a slightly larger mass of approximately 1.008 amu. Electrons, on the other hand, have a much smaller mass of approximately 0.0005 amu.

The number of protons and neutrons in an atom determines its atomic mass, which is the sum of the masses of all its protons and neutrons. The number of electrons determines the chemical properties of an atom and how it interacts with other atoms.

In summary, subatomic particles, such as protons, neutrons, and electrons, do not have the ability to increase or decrease the size and mass of an atom. Rather, they determine the fundamental properties of an atom, including its size, mass, and chemical behaviour.

The molar mass of hydrogen (H2) is 2.016 g/mol. Therefore, the mass of 9 moles of hydrogen is: 9 mol x 2.016 g/mol = 18.144 g. So, 18.144 grams of hydrogen must react with 3 moles of nitrogen completely.

Ammonia is useful in many ways, including fertilizer production, household cleaning product, refrigeration, water treatment, textile production and fuel production.

Ammonia is a key component of fertilizer because it contains nitrogen, an essential nutrient for plant growth. Plants require nitrogen to build proteins and other essential molecules. While nitrogen is abundant in the atmosphere, plants cannot use it in its gaseous form. Instead, nitrogen must be converted into a usable form, such as ammonia, through a process called nitrogen fixation.

The balanced chemical equation for the reaction between nitrogen and hydrogen to form ammonia is N2 + 3H2 → 2NH3.

To react completely with 3 moles of nitrogen,

3 moles N2 x 3 moles H2 / 1 mole N2 = 9 moles H2

The molar mass of hydrogen (H2) is 2.016 g/mol. Therefore, the mass of 9 moles of hydrogen is: 9 mol x 2.016 g/mol = 18.144 g

As the molarity of a solution increases, the absorbance readings of the solution typically increase.

This is because an increase in molarity generally corresponds to an increase in the concentration of the absorbing species in the solution, which in turn leads to an increase in the number of absorbing particles that can interact with the incident light.

The relationship between absorbance and concentration of a solution is described by the Beer-Lambert law, which states that the absorbance of a solution is proportional to the concentration of the absorbing species and the path length of the light through the solution. Thus, an increase in the concentration of the absorbing species (i.e. the molarity of the solution) leads to an increase in the number of particles that can interact with the light, resulting in a higher absorbance reading.

It's worth noting that this relationship between molarity and absorbance is not always linear, and may depend on the specific properties of the absorbing species and the solvent in which it is dissolved. Additionally, if the concentration of the absorbing species becomes too high, the solution may become opaque and the absorbance readings may no longer be meaningful.

A nucleic acid sequence that is palindromic, meaning it reads the same forward and backward, could form a perfectly base-paired, double-stranded molecule with itself.

Palindromic sequences are nucleic acid sequences that read the same forward and backward, and they can form perfectly base-paired, double-stranded molecules with themselves. In DNA, palindromic sequences are typically four or more nucleotides in length, and they can be recognized by their symmetry around a central axis. For example, the sequence 5'-CGCG-3' is a palindromic sequence that can base-pair with its complementary sequence 3'-GCGC-5' to form a double-stranded structure. Similarly, RNA sequences can also be palindromic and form double-stranded structures. RNA palindromic sequences tend to be longer and more complex than DNA palindromes, but they also base-pair with their complementary sequences to form double-stranded structures. Palindromic sequences can be found in various regions of the genome, including regulatory regions and coding sequences. They play important roles in DNA replication, gene expression, and recombination.

Explanation:

x is 1. Sodium chloride (NaCl) is a binary ionic compound composed of sodium (Na) cations and chloride (Cl) anions.

The empirical formula for sodium chloride is NaCl, which means that each formula unit of sodium chloride contains one sodium cation (Na+) and one chloride anion (Cl-).

Since the compound was found to contain 29.0% of chlorine by mass, the molar mass of the compound can be determined as follows:

Mass of Cl = 29.0 g Cl / 100 g compound

Mass of Na = 71.0 g compound - 29.0 g Cl

Moles of Cl = Mass of Cl / Atomic mass of Cl

Moles of Na = Mass of Na / Atomic mass of Na

Since the ratio of sodium cations to chloride anions is 1:1, the number of moles of sodium cations is equal to the number of moles of chloride anions. The empirical formula for the compound is therefore NaCl, and the value of x is 1.

If lithium hydroxide reacts with gaseous carbon dioxide to form solid lithium carbonate and liquid water. then 0.915 g of carbon dioxide would react with 1.00 g of lithium hydroxide.

The balanced chemical formula for the reaction of carbon dioxide and lithium hydroxide is:

Li2CO3 + H2O = 2 LiOH + CO2.

According to the equation, which is balanced, two moles of LiOH and one mole of CO2 combine to form one mole of Li2CO3.

We must convert the mass of LiOH to moles in order to determine how much CO2 is needed to react with 1.00 g of LiOH. LiOH has a molar mass of:

Lithium's atomic mass is 6.94 and its atomic masses are 15.9994, 1.0079, and 23.95 g/mol respectively.

Hence, 1.00 g of LiOH equals:

1.00 g / 23.95 g/mol equals 0.0417 moles of LiOH

The balanced equation states that 2 moles of LiOH and 1 mole of CO2. The amount of moles of CO2 needed to react with 0.0417 mol of LiOH is therefore:

0.0208 mol CO2 = 0.0417 mol LiOH x (1 mol CO2 / 2 mol LiOH)

Lastly, we can use the molar mass of CO2 to convert the quantity of moles of CO2 to grammes, which is:

1 atomic mass of C plus 2 atomic masses of O equals 44.01 g/mol.

44.01 g/mol times 0.0208 mol CO2 equals 0.915 g CO2

The pKb for the hypochlorite ion (OCl-) can be calculated using the relationship between the Ka and the Kb of the acid and its conjugate base.

Kw = Ka * Kb

where Kw is the ion product constant of water (1.0 x [tex]10^{-14}[/tex] at 25°C).

At 25°C, the pKa for HOCl can be calculated as:

pKa = -log(Ka) = -log(3.0 x [tex]10^{-8}[/tex]) = 7.52

The pKb for OCl- can be calculated using the following formula:

pKb = pKw - pKa = 14.00 - 7.52 = 6.48

Therefore, the pKb for hypochlorite ion is 6.48. Rounded to three significant figures, the answer is 6.49.
