How many molecules of water are needed to completely hydrolyze a polymer that is 10 monomers long.

Consider the molecular orbital model of benzene. In the ground state, how many molecular orbitals are filled with electrons is C. 3

In the molecular orbital model of benzene, the ground state refers to the lowest energy state of the molecule. Benzene has 12 electrons, with six of these electrons forming a delocalized π-system that contributes to its aromatic properties.

To determine the number of molecular orbitals filled with electrons, we can look at the molecular orbitals formed by the π-system. In benzene, there are six π molecular orbitals created by the overlapping of the p-orbitals from each of the six carbon atoms. These π molecular orbitals can be classified into three bonding (lower energy) and three antibonding (higher energy) orbitals.

In the ground state, the electrons fill the molecular orbitals from the lowest energy level to the highest. The six π electrons in benzene fill the three lower energy-bonding molecular orbitals, with each orbital containing two electrons. Therefore, there are 3 molecular orbitals filled with electrons in the ground state of benzene. Therefore the correct option is C.

The amount of water removed from every kilogram of commercial sea salt would be 27.57 kg.

Seawater contains 3.5% sodium chloride by mass. This means every 1 kg of seawater contains 0.035 kg of sodium chloride.

Sea salt contains about 10% water. This means every 1 kg of sea salt contains 0.1 kg of water.

In order to calculate the amount of water removed from every kilogram of commercial sea salt produced, we need to know the amount of seawater that will give 1 kilogram of sea salt.

We said every 1 kg of seawater contains 0.035 kg of salt. How many 0.035 kg can be found in 1kg?

1/0.035 = 28.57

This means 28.57 kg of seawater would need to be processed in order to have 1 kg of salt. Thus, the amount of water removed can be calculated as:

28.57 - 1 = 27.57 kg

In other words, about 27.57 kg of water is removed for every kilogram of commercial salt produced.

To determine the pH of a solution using a pH indicator paper, you need a color chart or a color scale that corresponds to different pH values.

This color chart or scale is used to compare the color of the pH indicator paper after it has been immersed in the solution. The pH indicator paper is impregnated with a universal pH indicator, which is a chemical compound that changes color depending on the acidity or alkalinity of the solution.

The indicator undergoes a chemical reaction with the hydrogen ions (H+) or hydroxide ions (OH-) present in the solution, resulting in a color change.

By comparing the color of the pH indicator paper with the color chart or scale, you can determine the approximate pH of the solution. The color chart usually provides a range of colors corresponding to different pH values, allowing you to match the observed color to the nearest pH value.

In the hypothesis mentioned, the aim is to calibrate a cabbage pH indicator using the pH values obtained from a universal pH indicator. Therefore, in addition to the pH indicator paper and color chart, you would also need a range of solutions with known pH values to establish a calibration curve specific to the cabbage pH indicator.

In summary, to determine the pH of a solution using a pH indicator paper, you need a color chart or scale that correlates the observed color of the pH indicator paper with different pH values. This chart or scale serves as a reference for interpreting the color change and determining the pH of the solution.

Answer: COLOR KEY

Explanation: CS

Option (d), P=ATC=MR=MC, accurately represents the long-run equilibrium condition for perfect competition, reflecting the balance between price and cost for firms operating in a competitive market.

The long-run equilibrium condition for perfect competition is that price (P) is equal to average total cost (ATC), which is also equal to marginal cost (MC), and marginal revenue (MR).

Option (d), P=ATC=MR=MC, best represents the long-run equilibrium condition for perfect competition. In perfect competition, firms operate at the minimum point of their average total cost curve, where price equals both average total cost and marginal cost. This condition ensures that firms are earning zero economic profit and are producing at an efficient level.

In the long run, if firms are earning economic profit, new firms will enter the market, increasing competition and driving prices down. Conversely, if firms are experiencing losses, some firms may exit the market, reducing competition and causing prices to rise. This process continues until firms reach a state where price equals average total cost, marginal cost, and marginal revenue, ensuring a long-run equilibrium.

Therefore, option (d), P=ATC=MR=MC, accurately represents the long-run equilibrium condition for perfect competition, reflecting the balance between price and cost for firms operating in a competitive market.

Explanation:

Molarity=(number of moles of solute)/(litres of solution)

In this case, we need to find moles of potassium bromide.

Mass=25.3g

Molar mass= 119g/mol

moles=(mass/molar mass)

        =(25.3)/(119)

        =0.2126moles of potassium bromide

Molarity=(0.2126)/(150/1000)

       ~1.417M

Hope this helps:)

Answer:

\(\boxed {\boxed {\sf molarity \approx 1.42 \ M \ KBr}}\)

Explanation:

Molarity is a measure of concentration in moles per liter.

\(molarity= \frac{moles \ of \ solute}{ liters \ of \ solution}}\)

We have the compound potassium bromide. Potassium (K) has an oxidation state of +1 and bromine (Br) has -1. They bond in a 1:1 ratio, so the formula is KBr.

We are given the amount of solute in grams, but we need moles. To convert, we use the molar mass. These values are found on the Periodic Table. They are the same as the atomic masses, but the units are grams per moles (g/mol) instead of atomic mass units (amu).

Look up the individual element's molar mass.

The formula of KBr contains no subscripts, so we can add the molar masses.

Use the molar mass as a ratio.

\(\frac {118.998 \ g\ KBr}{ 1 \ mol \ KBr}\)

We want to convert 25.3 grams, so we multiply by that value.

\(25.3 \ g\ KBr*\frac {118.998 \ g\ KBr}{ 1 \ mol \ KBr}\)

Flip the ratio so the units of grams of KBr cancel.

\(25.3 \ g\ KBr*\frac{ 1 \ mol \ KBr}{118.998 \ g\ KBr}\)

\(25.3*\frac{ 1 \ mol \ KBr}{118.998} = 0.2126086153\ mol \ KBr\)

Molarity uses liters, so we must convert the 150 milliliters. 1 liter contains 1000 milliliters.

\(\frac{1 \ L }{1000 \ ml}\)

\(150 \ mL *\frac{1 \ L }{1000 \ ml}\)

\(150 *\frac{1 \ L }{1000}= 0.150 \ L\)

Now we have the moles of solute and liters of solution, so we can find molarity.

\(molarity= \frac{ moles \ of \ solute}{liters \ of \ solution}\)

\(molarity= \frac{0.2126086153 \ mol \ KBr}{ 0.150 \ L}\)

\(molarity = 1.417390768\ mol KBr/L\)

The original measurements had 3 significant figures, so our answer must have the same. For the number we found, that is the hundredth place. The 7 in the thousandth place tells us to round the 1 to a 2.

\(molarity \approx 1.42 \ mol KBr/L\)

1 mole per liter is equal to 1 Molar (M), so we must convert the units.

\(molarity \approx 1.42 \ M \ KBr\)

Answer:

Explanation:

The equation for the reaction of lithium with water to produce lithium hydroxide and hydrogen gas is:

Li + H2O -> LiOH + H2

To balance this equation using the electron-transfer method, we first need to determine the oxidation states of each element in the reactants and products.

In Li, the oxidation state of lithium is +1. In H2O, the oxidation state of hydrogen is +1 and oxygen is -2.

In LiOH, the oxidation state of lithium is +1, oxygen is -2 and hydrogen is +1.

In H2, the oxidation state of hydrogen is +1.

It's clear that lithium loses 1 electron to become Li+ and hydrogen gains 1 electron to become H-.

So, we have to add an electron on the right side of the equation to balance the electrons.

Li + H2O -> LiOH + H2 + e-

Now, the number of electrons on both sides of the equation is the same and the equation is balanced.

Alternatively, we can use the oxidation number method, where we balance the charge of the reactant and product side of the equation. The sum of the oxidation numbers of all atoms on the reactant side must equal the sum of the oxidation numbers of all atoms on the products side. In this case, the oxidation state of lithium is +1, hydrogen is +1 and oxygen is -2.

Li + H2O -> LiOH + H2

+1 +1 -2 = +1 +1 +1 -2

The equation is already balanced with respect to oxidation numbers
