The statement that is true about Earth's water distribution is that the majority of the Earth's water is in the oceans.

Water is a transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients. Its chemical formula is H20, meaning each of its molecules contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water plays an important role in the world economy, as it functions as a solvent for a wide variety of chemical substances and facilitates industrial cooling and transportation. It is also essential for sanitation, hygiene, and the production of hydroelectric power.

This is evident from the graph, which shows that the oceans make up about 97% of Earth's water, while the other 3% is composed of freshwater lakes, rivers, and groundwater. This indicates that the vast majority of Earth's water is in the oceans, and that there is only a small amount of freshwater available for human use.

When the precipitate is washed, dried and weighed, then the percent by mass of silver in the alloy is 100%.

First, we need to determine the mass of the silver in the precipitate. We can do this by subtracting the mass of the filter paper from the mass of the filter paper and dried precipitate:

mass of precipitate = (mass of filter paper and dried precipitate) - (mass of filter paper)

mass of precipitate = 1.9332 g - 0.50000 g = 1.4332 g

Since all the silver in the alloy was converted to silver ions and then precipitated as silver chloride, the mass of silver in the precipitate is equal to the mass of silver in the original alloy. Therefore, the percent by mass of silver in the alloy is:

percent by mass of silver = (mass of silver / mass of alloy) x 100%

We just need to solve for the mass of silver. We know that the mass of the alloy was 4.3148 g, so the mass of silver must be:

mass of silver = mass of alloy - mass of other elements

Since we're assuming the alloy is pure silver and other elements, we can simply subtract the mass of the other elements from the mass of the alloy to get the mass of silver. We don't have information about the mass of other elements, but we can assume it's small enough to be negligible.

So, we have:

mass of silver = 4.3148 g - 0 g (assumed negligible) = 4.3148 g

Now we can calculate the percent by mass of silver:

percent by mass of silver = (mass of silver / mass of alloy) x 100%

percent by mass of silver = (4.3148 g / 4.3148 g) x 100%

percent by mass of silver = 100.00%

To calculate the number of moles of AgNO₃ used in an experiment, we need to know the mass of AgNO₃ weighed out and the molar mass of AgNO₃.

By adding the atomic masses of the component elements, it is possible to get the molar mass of AgNO₃: AgNO₃ = Ag + N + 3O.

AgNO₃'s molar mass = as (1 × Ag atomic mass) + (1 × N atomic mass) + (3 × atomic mass of O)

AgNO₃'s molar mass = 1 × 107.87 g/mol + 1 × 14.01 g/mol + 3 × 16.00 g/mol.

∴ AgNO₃'s molar mass = 169.87 g/mol.

By dividing the mass of weighed-out AgNO₃ by its molar mass, we can now determine how many moles of AgNO₃ were utilized in the experiment:

AgNO₃'s mass and molar mass are used to calculate its moles.

For example: if 2.5 grams of AgNO₃ were weighed out at the beginning of the experiment, the calculation would be:

moles of AgNO₃ = 2.5 g ÷ 169.87 g/mol

moles of AgNO₃ = 0.0147 mol

The concentrations of each ion remaining in solution after the precipitation is complete are [Fe2+] = 0.0375 M, [PO43-] = 0.01875 M, [K+] = 0.1125 M, and [CH3COO-] = 0.0375 M.

What is Precipitation ?

Precipitation can occur in a variety of chemical reactions, but it is most commonly associated with double displacement reactions, where two ionic compounds are mixed together and the cations and anions switch partners. If one of the resulting products is insoluble, it will form a solid that will settle to the bottom of the container.

To solve this problem, we need to determine the products of the reaction between potassium phosphate (K3PO4) and iron (II) acetate (Fe(CH3COO)2), which will result in the precipitation of an insoluble salt.

The balanced chemical equation for the reaction is:

2Fe(CH3COO)2 + 3K3PO4 → Fe3(PO4)2 + 6CH3COOK

From the equation, we can see that the products of the reaction are iron(III) phosphate (Fe3(PO4)2) and potassium acetate (CH3COOK).

To determine the concentrations of the ions remaining in solution, we can use the following steps:

Calculate the number of moles of potassium phosphate and iron (II) acetate in the solutions:

moles of K3PO4 = 0.0750 M x 0.0750 L = 0.005625 mol

moles of Fe(CH3COO)2 = 0.0750 M x 0.0750 L = 0.005625 mol

Determine the limiting reactant. Since the stoichiometric ratio of K3PO4 to Fe(CH3COO)2 is 3:2, we can see that the limiting reactant is Fe(CH3COO)2, since we have an equal number of moles of both reactants.

Use the stoichiometry of the balanced chemical equation to calculate the number of moles of the products:

moles of Fe3(PO4)2 = (0.005625 mol Fe(CH3COO)2) x (1 mol Fe3(PO4)2 / 2 mol Fe(CH3COO)2) = 0.002813 mol

moles of CH3COOK = (0.005625 mol Fe(CH3COO)2) x (6 mol CH3COOK / 2 mol Fe(CH3COO)2) = 0.016875 mol

Calculate the concentrations of the remaining ions by subtracting the number of moles of the reactants from the number of moles of the initial solution and dividing by the total volume:

[Fe2+] = (0.005625 mol - 0 mol) / 0.150 L = 0.0375 M

[PO43-] = (0.005625 mol - 0.002813 mol) / 0.150 L = 0.01875 M

[K+] = (0.016875 mol - 0 mol) / 0.150 L = 0.1125 M

[CH3COO-] = (0.005625 mol - 0 mol) / 0.150 L = 0.0375 M

Therefore, the concentrations of each ion remaining in solution after the precipitation is complete are [Fe2+] = 0.0375 M, [PO43-] = 0.01875 M, [K+] = 0.1125 M, and [CH3COO-] = 0.0375 M.

In chemistry, concentration is a measure of the amount of a substance in a given volume of a solution or mixture. It is usually expressed in terms of the number of moles of the substance per liters of solution or mixture.

We have an equilibrium constant of Ke = 1.2 at 375°C and the starting concentrations are [H2]0 = 0.76 M, [N2]0 = 0.60 M, and [NH3]0 = 0.48 M.

Concentration at equilibrium is,

N2(g) + 3H2(g) — 2 NH3 (g)

We shall determine whether the reaction will move forward or backward by calculating the reaction Q. If Q < K, the reaction will proceed forward so the concentration of reactants will decrease and that of products will increase. The opposite will happen if Q> K (reaction proceeds backwards).

[tex]Q= \frac{NH_{3} ^{2} }{[N_{2} ] [H_{2}]^{3} } = \frac{0.48^{2} }{(0.60) (0.76)^{3} } = 0.87[/tex]

Since Q < [tex]K_{cr}[/tex], the reaction will proceed forward. Therefore, the concentration of reactants N2 and H2 will decrease while the concentration of the product NH3 will increase.

c. Removing some CO (g)

d. Removing some Caco, (s)

The correct answer is B.Bromodimethylbenzene B cannot undergo nucleophilic aromatic substitution

By treatment with sodium amide in liquid ammonia because the two bromine atoms attached to the benzene ring are meta-directing, which would prevent the reaction from occurring.Bromodimethylbenzene is an organic compound made up of a benzene ring with two bromine atoms and two methyl groups attached. It is a colorless liquid at room temperature and has a slightly sweet odor. It is used as an intermediate in the production of a variety of organic compounds, such as dyes and pharmaceuticals. It can also be used as a solvent for various compounds. Bromodimethylbenzene is a toxic substance and should be handled with caution.

To calculate the total pressure of the mixture, we need to add up the partial pressures of all the gases in the mixture. The partial pressures given are:

Ar: 749 torr

O2: 11,235 torr

N2: 803 torr

Other gases (assumed to be negligible): 699 torr

Therefore, the total pressure of the mixture is:

749 torr + 11,235 torr + 803 torr + 699 torr = 13,486 torr

Therefore, the total pressure of the mixture is 13,486 torr.

The overall pressure ptot is the total of all pressures in a reference system. This pressure, according to Bernoulli (see Fluid mechanics), consists of the static pressure p, the dynamic pressure pdyn, and the geodetic component ( g z) that exists in a fluid along a stream line in a frictionless flow.

The total pressure of a gas mixture is the sum of its component gases' partial pressures: Ptot = ∑Pi = P1 + P2 + P3... ntot = total number of moles in the gas mixture (the sum of all ni).
