a 10 gram ball is rolling at 20 m/s. what energy does the ball have

Answer:

33.0 L

Explanation:

Step 1: Given data

Step 2: Convert the temperatures to the Kelvin scale

We will use the following expression.

K = °C + 273.15

T₁: K = 25.00°C + 273.15 = 298.15 K

T₂: K = 55.00°C + 273.15 = 328.15 K

Step 3: Calculate the final volume of the balloon

If we assume ideal behavior, we can calculate the final volume of the balloon using Charles' law.

V₁/T₁ = V₂/T₂

V₂ = V₁ × T₂/T₁

V₂ = 30.0 L × 328.15 K/298.15 K = 33.0 L

Answer:

A phase change is occurring; the liquid water is changing to gaseous water, or steam. On a molecular level, the intermolecular forces between the water molecules are decreasing. The heat is providing enough energy for the water molecules to overcome these attractive forces.

The phase transition takes place at the molecular level by changing the strength of intermolecular forces between the molecules.

Phase changes can be defined as the physical processes of transition between a state of a medium, identified by some parameters. These changes in states of matter that can be written as liquid, gas, solid, and plasma.

A particular phase in a thermodynamic system exhibits uniform physical properties. During a phase transition, some properties of the medium change, because of the change in external conditions, such as temperature, and pressure.

In a solid state, the molecules are compactly bound by a strong force of attraction. In the liquid state, the molecules have lesser attraction forces. The phase changes depend upon the temperature and pressure.

Therefore, phase transitions occur on a molecular level as the alteration in the strength of intermolecular forces.

Answer: [tex]5.15\times 10^5kg[/tex]

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number of particles.

To calculate the number of moles, we use the equation:

Putting in the values we get:

[tex]\text{Number of moles}=\frac{1.00\times 10^{31}}{6.023\times 10^{23}}=0.166\times 10^{8}moles[/tex]

1 mole of phosphorous [tex]P[/tex] weighs = 31 g

Thus [tex]0.166\times 10^8[/tex] moles of phosphorous [tex]P[/tex] weigh=[tex]\frac{31}{1}\times 0.166\times 10^8=5.15\times 10^8g=5.15\times 10^5kg[/tex]

Answer:

2) ch4 because 8 electrons are shared in this molecule

Explanation:

The bond between carbon and hydrogen in the molecule; CH4 is a covalent bond. This bond involves sharing of electrons. Carbon has a valency of 4 and needs four more electrons to complete it's electronic configuration. These 4 electrons are taken care of by the 4 hydrogen atoms which each have a valency of 1.

Answer:

7.12 × 10⁻³ M/s

Explanation:

Step 1: Write the balanced reaction

2 SO₂ + O₂ ⇒ 2 SO₃

Step 2: Establish the appropriate molar ratio

According to the balanced equation, the molar ratio of O₂ to SO₃ is 1:2.

Step 3: Calculate the rate of formation of SO₃

The rate of loss of O₂ is 3.56 × 10⁻³ mol O₂/L.s. The rate of formation of SO₃ is:

3.56 × 10⁻³ mol O₂/L.s. × 2 mol SO₃/1 mol O₂ = 7.12 × 10⁻³ mol SO₃/L.s

Answer:

0.0153 mol

Explanation:

Mass of crucible and lid: 29.307 g

Mass of crucible, lid, and silver: 30.958 g

Number of moles = Mass /Molar mass

Mass of Silver = Mass of crucible, lid, and silver  -  Mass of crucible and lid

Mass of siilver = 30.958 g - 29.307 g

Mass of silver = 1.651 g

Molar mass of silver = 107.868 g/mol

Number of moles = 1.651 g / 107.868 g/mol

Number of moles = 0.0153 mol

Answer:

123.2 Liters.

Explanation:

At STP (T = 273K & P = 1atm), one mol of any gas will occupy 22.4 liters.

With the above information in mind, we can calculate how many liters would 5.500 mol of gas occupy:

5.500 mol * 22.4 L / mol = 123.2 L

So 5.500 moles of C₃H₃ would have a volume of 123.2 liters at STP.

Explanation:

During periods of strenuous activity muscle cells run low on oxygen.

Muscle cells are defined as the cellular components of muscle tissue.  Muscle cells are designed to contract, or produce a pulling force, in order to stabilize or move different body parts. Skeletal, visceral, and heart muscle cells are the three different types. They are located in the organs' hollow walls. The muscular system is made up of a variety of muscle types, each of which is essential to how the body works.

Lactic acid is produced and accumulates in the muscle when there is a high energy demand, rapid changes in the energy requirement, and a lack of oxygen. During prolonged, intense activity, muscle pH falls to 6.4–6.6. Your muscles are forced to contract as forcefully as they can during this form of exercise, which results in an increase in the number of contractile filaments in your muscle cells.

Thus, during periods of strenuous activity muscle cells run low on oxygen.

The bond angles around carbon in the triple bond are 180 degrees and it is sp hybridized. option B is correct

This hybridization process involves mixing the valence s orbital with one of the valence p orbitals to yield two equivalent sp hybrid orbitals that are oriented in a linear geometry.

The set of sp orbitals appears similar in shape to the original p orbital, but there is an important difference. The number of atomic orbitals combined always equals the number of hybrid orbitals formed.

The p orbital is one orbital that can hold up to two electrons. The sp set is two equivalent orbitals that point 120° from each other. The two electrons that were originally in the s orbital are now distributed to the two sp orbitals, which are half filled.

Therefore, due to the sp hybrid and 120-degree angle option B is correct

Answer:

404 persons

Explanation:

To get n= number of persons

We use this formula

n = I(Dc - EaC)Eaf

I = 6000 = inflow rate

Dc = desired concentration = 1000

Eac = Exhaled air concentration = 280ppm = 0.00028

Exhaled air flow rate = Eaf = 0.0107

When we put values into the formula above

6000(0.001-0.00028)/0.0107

= 6000(0.00072)/0.0107

= 4.32/0.0107

= 403.7

= 404 persons
