Answer:

1.56x10^23 atoms of Mn

Explanation:

250 grams of braunite (Mn3SiO6) is:

  (250 g)/(288.91 g/mole) = 0.865 moles of Mn3SiO6

One mole of Mn3SiO6 would contain 3 moles of Mn, since it appears 3 times in the compound.  Breaking apart 1 mole of Mn3SiO6 into individual atoms of each element would procude 3 moles of Mn atoms (and 1 mole of Si and 6 moles of O atoms),

Since we have 0.865 moles of Mn3SiO6,

we should have:

    (0.865 moles of Mn3SiO6)*((3 moles of Mn)/(1 mole Mn3SiO6))

 this is equal to 2.596 moles of Mn atoms

Since 1 mole is 6.02x10^23 particles of anything, we can write:

(2.596 moles of Mn)*(6.02x10^23 particles Mn atoms/mole) =

          1.56x10^23 atoms of Mn

A. They can end up as waste products that sometimes can’t be recycled.

B. They sometimes release toxins into the environment.

C. They use materials from Earth that are nonrenewable.

Explanation:

A. Synthetic polymers, such as plastic, can end up as waste in landfills, oceans, and other natural areas. This can cause a variety of environmental problems, as some types of plastic do not break down easily and can persist in the environment for decades or even centuries. This accumulation of waste can have negative impacts on wildlife, ecosystems, and human health.

B. Some synthetic polymers are made using harmful chemicals that can leach out and release toxins into the environment. These toxins can have negative impacts on wildlife, ecosystems, and human health. For example, some types of plastic contain chemicals such as bisphenol-A (BPA) that have been linked to hormone disruption and other health problems.

C. The production of synthetic polymers often requires the use of nonrenewable resources, such as petroleum and natural gas. These resources are finite and their extraction and processing can cause environmental damage, including air and water pollution and habitat destruction. The continued use of these nonrenewable resources can exacerbate environmental problems and contribute to climate change.

These are three ways that synthetic polymers can affect the environment, and it's important to consider the impacts of these materials in order to minimize their negative effects and promote sustainability.

Boyle's law, likewise alluded to as the Boyle-Mariotte law, or Mariotte's regulation (particularly in France), is an exploratory gas regulation that portrays the connection among tension and volume of a bound gas. Boyle's law has been expressed as: Numerically, Boyle's regulation can be expressed as: or where P is the pressure of the gas, V is the volume of the gas, and k is a consistent. Boyle's law expresses that when the temperature of a given mass of restricted gas is constant, the result of its pressure and volume is likewise inversely proportional to each other.

According to boyle's law total pressure of any tank will be pressure exerted by it on a total volume of container.

In other words,pressure exerted by each tank =pressure value  × (total volume of container)

Therefore,

From first tank, pressure is  =7.2 × [15L/(15+8.3)]

=>pressure of first tank is = 7.2 ×(15/23.3)

=>pressure of first tank is =7.2×0.64377=4.635atm

Now,pressure of second tank is =4.1 × [8.3 / (8.3+15) ]

=>pressure of second tank is =(4.1) × [8.3 / 23.3]

=>pressure of second tank is =4.1×0.356=1.46atm

Therefore,total pressure exerted by two tanks combines=1.46atm + 4.635atm=6.095atm=6.1atm.

The molality of HCl in the solution is[tex]0.00122 mol/kg[/tex]

Molality is defined as the number of moles of a solute in one kilogram of a solvent. In this case, the solvent is water.

To calculate the molality, we first need to calculate the molarity of the solution. Molarity is defined as the number of moles of a solute in one liter of solution.

To calculate the molarity, we need to know the mass of the solute (HCl) and the volume of the solution. The mass of the solute can be calculated using the density of the solution (1.22 g/ml):

Mass of HCl =[tex]Density * Volume[/tex]

Volume = [tex]\frac{Mass}{Density }[/tex]

Volume =[tex]\frac{(12.0 mol/L) }{ (1.22 g/ml) }= 9.839 L[/tex]

Molarity = [tex]\frac{ (12.0 mol/L) }{(9.839 L) }= 1.22 mol/L[/tex]

Now, we can calculate the molality:

Molality = [tex]\frac{ (1.22 mol/L) }{(1000 g/kg) }= 0.00122 mol/kg[/tex]

Therefore, the molality of HCl in the solution is [tex]0.00122 mol/kg[/tex].

At the same temperature, the gas has a 2.5 L volume at 7.0 atm. Volume in the context of gases is the quantity of space a gas takes up.

The ideal gas law, which connects a gas's pressure, volume, and temperature, can be used to solve this issue. PV = nRT. Assuming that the temperature stays constant, we may apply the ideal gas law in the following manner: P1V1 = P2V2. With the supplied values plugged in, we obtain (5.0 atm)(3.5 L) = (7.0 atm) (V2). We can calculate V2 as follows: V2 = (5.0 atm)(3.5 L) / (7.0 atm) = 2.5 L. As a result, the gas has a 2.5 L volume at the same temperature at 7.0 atm. In many industrial, scientific, and medical applications, accurate gas volume measurement and management are crucial.

In the given sample, when the water level is rises from 23.8ml to 28.5 ml,  the density of the metal is 5.00 g/cm³

To find the density of the metal, we need to use the formula:

density = mass / volume

We are given the mass of the metal as 23.5 g. To find the volume of the metal, we need to subtract the initial volume of water in the cylinder from the final volume of water after the metal is added. The difference in volume is equal to the volume of the metal.

The initial volume of water is 23.8 ml, and the final volume of water is 28.5 ml, so the volume of the metal is:

volume = final volume - initial volume

volume = 28.5 ml - 23.8 ml

volume = 4.7 ml

Now we can substitute the values for mass and volume into the density formula:

density = mass / volume

density = 23.5 g / 4.7 ml

We need to convert the volume to cubic centimeters (cm³) because the units of density are expressed in g/cm³.

1 ml is equal to 1 cm³, so:

To dilute the triamcinolone injectable suspension from 10mg/ml to 0.125 mg/ml, we need to dilute it 80 times (since 10 ÷ 0.125 = 80). This means that we need to add 1 part of the 10mg/ml suspension to 79 parts of distilled water.

To calculate how much of each we need, we can use the following formula:

C1V1 = C2V2

where C1 is the initial concentration (10mg/ml), V1 is the initial volume (unknown), C2 is the final concentration (0.125mg/ml), and V2 is the final volume (480ml).

First, we can solve for V1:

C1V1 = C2V2

10mg/ml x V1 = 0.125mg/ml x 480ml

V1 = (0.125mg/ml x 480ml) / 10mg/ml

V1 = 6ml

So we need 6ml of the 10mg/ml triamcinolone injectable suspension.

Next, we can calculate how much distilled water we need to add:

Total volume - volume of triamcinolone suspension = volume of distilled water

480ml - 6ml = 474ml

Therefore, we need to add 6ml of the 10mg/ml triamcinolone injectable suspension and 474ml of distilled water to make 480ml of the final product with a concentration of 0.125mg/ml.
