Answer: The new temperature of container is 123 K.

Explanation:

Given: [tex]P_{1}[/tex] = 795 mm Hg,     [tex]T_{1}[/tex] = 273 K

[tex]P_{2}[/tex] = 358 mm Hg,          [tex]T_{2}[/tex] = ?

Formula used to calculate the new temperature is as follows.

[tex]\frac{P_{1}}{T_{1}} = \frac{P_{2}}{T_{2}}[/tex]

Substitute the values into above formula as follows.

[tex]\frac{P_{1}}{T_{1}} = \frac{P_{2}}{T_{2}}\\\frac{795 mm Hg}{273 K} = \frac{358 mm Hg}{T_{2}}\\T_{2} = 123 K[/tex]

Thus, we can conclude that the new temperature of container is 123 K.

Answer: A biome is part of the biosphere. Biomes can influence each other. terrestrial biomes

Explanation:

We are given:

Volume of gas = 3.8 L

Pressure = 460 mmHg

Temperature = 77°c = (77+273)K = 350K

Converting the pressure to atm:

Pressure(in atm)  = Pressure(in mmHg) / 760

Pressure = 460/760 = 0.6 atm

Finding the number of moles:

using the ideal gas equation:

PV = nRT                                         [where R is the universal gas constant]

replacing the given values in this equation

(0.6)(3.8) = n(0.082)(350)

n = (0.6*3.8)/(0.082*350)

n = 0.08 moles

Explanation:

Taking into account the definition of molarity,  0.005 liters of a 6.0 M solution of acetic acid contain 0.0030 moles​.

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

[tex]molarity=\frac{number of moles}{volume} [/tex]

Molarity is expressed in units [tex]\frac{moles}{liters} [/tex].

In this case, you have a 6.0 M solution of acetic acid that contain 0.0030 moles​. Replacing in the definition of molarity:

[tex]0.6\frac{moles}{liters} =\frac{0.0030 moles}{volume} [/tex]

Solving:

0.6 [tex]\frac{moles}{liters} [/tex]× volume= 0.0030 moles

volume= 0.0030 moles ÷0.6 [tex]\frac{moles}{liters} [/tex]

volume=0.005 liters

Finally, 0.005 liters of a 6.0 M solution of acetic acid contain 0.0030 moles​.

Answer:

The tectonic style and viability of modern plate tectonics in the early Earth is still debated. Field observations and theoretical arguments both in favor and against the uniformitarian view of plate tectonics back until the Archean continue to accumulate. Here, we present the first numerical modeling results that address for a hotter Earth the viability of subduction, one of the main requirements for plate tectonics. A hotter mantle has mainly two effects: 1) viscosity is lower, and 2) more melt is produced, which in a plate tectonic setting will lead to a thicker oceanic crust and harzburgite layer. Although compositional buoyancy resulting from these thick crust and harzburgite might be a serious limitation for subduction initiation, our modeling results show that eclogitization significantly relaxes this limitation for a developed, ongoing subduction process. Furthermore, the lower viscosity leads to more frequent slab breakoff, and sometimes to crustal separation from the mantle lithosphere. Unlike earlier propositions, not compositional buoyancy considerations, but this lithospheric weakness could be the principle limitation to the viability of plate tectonics in a hotter Earth. These results suggest a new explanation for the absence of ultrahigh-pressure metamorphism (UHPM) and blueschists in most of the Precambrian: early slabs were not too buoyant, but too weak to provide a mechanism for UHPM and exhumation.

Explanation:

Molarity, M, is an unit of concentration widely used in analytical chemistry. Is defined as the ratio between the moles of solute (In this case, 5.46 moles) and liters of solution. To solve this question we must find the volume of the solution in liters in to find the molarity of the solution, as follows:

Liters solution:

840mL * (1L / 1000mL) = 0.840L

Molarity:

5.46moles / 0.840L

Answer:

c) 3570000

Explanation:

The standard form is a way to simplify too long or too short numbers. Standard form uses powers of ten to contract numbers.

x × 10^n

Where;

x = decimal number between 1.0 - 10.0

n = power of 10

According to this question, a number already in standard form is given as 3.57 x 10^6.

To convert to its long form, we count forward the power of ten beginning from where the decimal is. In this case, we're counting 6 times Note that once the decimal is after 7, we start placing zero (0) instead. Based on this, we have;

3.57 x 10^6

1st count = 35.7

2nd count = 357

3rd count = 3570

4th count = 35700

5th count = 357000

6th count = 3570000

Hence, the long form of the number 3.57 x 10^6 is 3570000.

Answer:

Freezing point of solution = -2.740C

Explanation:

The solution is attached herewith

The normal freezing point of an aqueous solution of C₁₂H₂₂O₁₁ is -1.26°C

The freezing point depression can be calculated using the formula:

ΔTf = i* Kf*m ; where

The molality of the aqueous solution of C₁₂H₂₂O₁₁ is first determined using the formula:

The mass of water is unknown but is determined from the mass of the solute and solution from the formula:

mass of solute = number of moles * molar mass

moles of solute in 1 L solution = 0.7439 moles

molar mass of solute, C₁₂H₂₂O₁₁ = 342.0 g/mol

mass of solute = 0.7439 moles * 342.0 g

mass of solute = 254.41 g

mass of solution = density * volume

volume of solution = 1 L = 1000 mL

mass of solution = 1.35g/ml * 1000 mL

mass of solution = 1350 g

Therefore, mass of solvent (water) = 1350 g - 254.41 g

mass of solvent (water) = 1095.59 g

mass of solvent (water) in kg = 1095.59 g * 1 kg/ 1000 g

mass of solvent (water) in kg = 1.0956Kg

Thus, molality of solution = 0.7439 moles / 1.0956 Kg

molality of solution = 0.679 mol/kg

The freezing point depression, ΔTf, is then determined using the formula: ΔTf = i* Kf*m

Since C₁₂H₂₂O₁₁ is a non-electrolyte; i for C₁₂H₂₂O₁₁ = 1

Kf of water = 1.86 kg/mole

m = 0.679 mol/kg

ΔTf = 1 * 1.86 * 0.679

ΔTf = 1.26 °C

Therefore, freezing point depression, ΔTf = 1.26 °C

normal freezing point of solution = freezing point of water - freezing point depression

normal freezing point of solution = 0.0°C - 1.26°C

normal freezing point of solution = -1.26°C

Therefore, the normal freezing point of an aqueous solution of C₁₂H₂₂O₁₁ is -1.26°C

Explanation:

Molarity is a measure of the molar concentration of a substance (solution). In relation to the volume, it is calculated using the formula as follows;

C1V1 = C2V2

Where;

C1 = initial concentration (M)

C2 = final concentration (M)

V1 = initial volume (L)

V2 = final volume (L)

According to the provided information in this question;

C1 = 14.38 M

C2 = ?

V1 = 1.28 L

V2 = 9.45 L

Using C1V1 = C2V2

14.38 × 1.28 = C2 × 9.45

18.4064 = 9.45 C2

C2 = 18.4064 ÷ 9.45

C2= 1.95 M

Answer:

72 g/L

Explanation:

The dissolved amount of solute is the difference between the amount you have poured and the amount that precipitated:

125 g - 35 g = 90 g

Thus, 90 grams of solute were dissolved in 1.25 liters. The saturation point is the ratio between the grams dissolved and the volume in liters:

saturation point = 90 g/1.25 L = 72 g/L
