Which statement is not
true?
A. The troposphere is responsible for nearly
all of Earth’s weather.
B. The exosphere reaches deep into space
and is the least dense layer.
C. The thermosphere typically breaks up
meteors before they hit Earth.
D. The stratosphere allows commercial
airlines to fly with less turbulence because
of fewer convection currents.

Answers

answer: C
explanation: to make C correct, the sphere that breaks up meteors is the mesosphere.

The atmosphere of the earth is layered and each layer of the atmosphere has its own properties. The atmosphere of the earth is divided into four layers. The thermosphere typically breaks up meteors before they hit Earth is not correct. The correct option is C.

What is mesosphere?

The four important layers of atmosphere are troposphere, stratosphere, thermosphere and mesosphere. The layer of the atmosphere which is found above the stratosphere is defined as the mesosphere. It is the coldest layer of the atmosphere.

A meteor is known as a celestial object which is made up of rocks and minerals which enters the atmosphere of the earth and burns out completely before reaching the surface of the earth. It is known as the shooting star or falling star.

The temperature of mesosphere drops with altitude. By 80 km it reaches 100 degree celsius. The meteors burn up in this layer not in thermosphere.

Thus the correct option is C.

How many moles of MgO are produced if 0.37 moles of O2 react with excess of Mg?

Answers

Answer:

yez so the answer is mg 1.0

Explanation:

The excess reactant is present in an amount that is greater than required. The amount of MgO that is produced in the reaction is 0.74 moles.

What is an excess reactant?

An excess reactant is that reantant thatis present in an amount that is more than required.

Now we are told that the magnessium is the reactant in excess so we have to use the amount of oxygen.

The reaction is: 2Mg + O2 ---->2MgO

1 mole of O2 produces 2 mole of MgO

0.37 moles of O2 produces 0.37 moles  * 2 moles/1 mole

= 0.74 moles

Answer:

The acidity or alkalinity of a solution depends upon its hydronium ion concentration and hydroxide ion concentration. The concentration of OH⁻ is 1 × 10⁻⁴ M.

What is pOH?

The pOH expresses the hydroxide ion concentration of a solution. The pOH of a solution is defined as the negative logarithm to the base 10 of the value of the hydroxide ion concentration in moles per litre.

The equation used to calculate the concentration of OH⁻ is:

pOH = -log [OH⁻]

[OH⁻] = 10⁻pOH

[OH⁻] = 10⁻⁴

= 0.0001 M

The number of significant figures in a reported value is the number of digits that are known with certainty plus the last one having some uncertainty.

Here 0.0001 contains 3 significant figures. In scientific notation it can be represented as 1 × 10⁻⁴ M.

Thus the concentration of [OH⁻] is 1 × 10⁻⁴ M.

3) A child has a toy balloon with a volume of 1.8 liters. The temperature of the balloon when it was filled was 22° C and the pressure was 1.0 atm. If the child were to let go of the balloon and it rose into the sky where the pressure is 0.86 atm and the temperature is 8° C, what would the new volume of the balloon be?​

Answers

This is a combined gas law problem, according to which

[tex]\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}[/tex]

where P is the pressure of the gas, V is the volume of the gas, and T is the temperature of the gas, and the subscripts 1 and 2 correspond to the initial and final conditions of the gas. In this problem, we are given the initial pressure, volume, and temperature of the gas in the balloon:

P₁ = 1.0 atm

V₁ = 1.8 L

T₁ = 295.15 K (K = °C + 273.15).

Moreover, we are given the final pressure and temperature of the gas in the balloon.

P₂ = 0.86 atm

T₂ = 281.15 K.

What we want to find is the final volume, V₂, which we can obtain by rearranging the combined gas equation to solve for V₂:

[tex]V_2=\frac{P_1V_1T_2}{T_1P_2} = \frac{(1.0 \text{ atm})(1.8 \text{ L})(281.15 \text{ K})}{(295.15 \text{ K})(0.86 \text{ atm})} \\ V_2 = 1.99 \text{ L}[/tex]

This answer has three significant figures. However, the question as written would warrant an answer that comprises one significant figure (as 8 °C has only one sig fig). In that case, the answer would be 2 L. If the answer is to be given to two significant figures, the volume would then be 2.0 L.

*specific heat of tin: 230 | specific heat of carbon: 709*

Which will provide more thermal energy and why?

2 kg of tin at 50 C
or
2 kg of carbon at 50 C

Answers

Answer:

tin

Explanation:

since it takes less heat to change it will warm up and produce thermal energy sooner than carbon

2 kg of carbon at 50°C will provide more thermal energy than 2 kg of tin at the same temperature.

To determine which substance will provide more thermal energy, we need to calculate the thermal energy for both scenarios using the formula:

Thermal energy = mass * specific heat * temperature change

For 2 kg of tin at 50°C:

Thermal energy = 2 kg * 230 J/kg°C * (50°C - 0°C) = 23,000 J

For 2 kg of carbon at 50°C:

Thermal energy = 2 kg * 709 J/kg°C * (50°C - 0°C) = 70,900 J

Therefore, 2 kg of carbon at 50°C will provide more thermal energy than 2 kg of tin at the same temperature. This is because carbon has a higher specific heat (709 J/kg°C) compared to tin (230 J/kg°C), meaning it requires more energy to raise the temperature of carbon compared to tin. As a result, carbon can store and release more thermal energy than tin at the same temperature and mass.

When two objects of different temperatures are placed in contact with one another, eventually: (choose one option from below)

b) their average kinetic energy will be the same
c) neither their average kinetic energy and temperature will be the same
d) their temperature will be the same

Answers

Answer:

a) both their average kinetic energy and temperature will be the same

Explanation:

Temperature is the measure of the average kinetic energy of a system. As temperature increases, so will kinetic energy. As kinetic energy increases, speed increases. As one decreases, so does the other. When two objects are in contact with each other, their molecules will exchange energy and cause an eventual equilibrium of temperature and kinetic energy.

If I have 0.275 moles of gas at a temperature of 75 K and a pressure of 1530 mmHg, what is the volume of the gas?

Answers

Answer: The volume of the gas is 0.84 Liters

Explanation:

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = 1530 mm Hg = 2.01 atm     (760mmHg=1atm)

V = Volume of gas = ?

n = number of moles = 0.275

R = gas constant =[tex]0.0821Latm/Kmol[/tex]

T =temperature =[tex]75K[/tex]

[tex]V=\frac{nRT}{P}[/tex]

[tex]V=\frac{0.275atm\times 0.0820 Latm/K mol\times 75K}{2.01atm}=0.84L[/tex]

Thus the volume of the gas is 0.84 Liters

What is the mass in grams of 0.250 mol CH2Cl2?

Answers

Answer:

21.2 grams CH2Cl2

Explanation:

Number of moles: .25

Molar mass of CH2Cl2: 84.93 g/mol

Mass in grams: 84.93(0.250) = 21.2325

Considering the definition of molar mass, the mass of 0.250 moles of CH₂Cl₂ is 21.225 grams.

Definition of molar mass

The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

The molar mass of a compound (also called Mass or Molecular Weight) is the sum of the molar mass of the elements that form it (whose value is found in the periodic table) multiplied by the number of times they appear in the compound.

Molar mass of CH₂Cl₂

In this case, you know the molar mass of the elements is:

C= 12 g/moleCl= 35.45 g/moleH= 1 g/mole

So, the molar mass of the compound CH₂Cl₂ is calculated as:

CH₂Cl₂= 12 g/mole + 2× 1 g/mole + 2× 35.45 g/mole

Solving:

CH₂Cl₂= 84.9 g/mole

Mass of 0.250 mol CH₂Cl₂

Next, you can apply the following rule of three: If by definition of molar mass 1 mole of the compound contains 84.9 grams, 0.250 moles of the compound contains how much mass?

[tex]mass=\frac{0.250 molesx84.9 grams}{1 mole}[/tex]

mass= 21.225 grams

The mass of 0.250 moles of CH₂Cl₂ is 21.225 grams.
