how many moles of water are in 1.23 times 10^18 water molecules

Answers

Answer:

The answer is 0.000002 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\ [/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{1.23\times {10}^{18} }{6.02 \times {10}^{23} } \\ = 0.00002043...[/tex]

We have the final answer as

A ball initially at rest is dropped from a window sill 14.2 m off the ground. Find the velocity of the ball the moment it hits the ground. Round your answer to 2 decimals places.

Answers

Answer:

16.68 m/s

Explanation:

The following data were obtained from the question:

Height (h) = 14.2 m

Initial Velocity (u) = 0 m/s

Final velocity (v) =?

Thus, the velocity (v) with which the ball hit the ground can be obtained as follow:

v² = u² + 2gh

NOTE: the acceleration due to gravity (g) = 9.8 m/s²

v² = u² + 2gh

v² = 0² + 2 × 9.8 × 14.2

v² = 0 + 278.32

v² = 278.32

Take the square root of both side

v = √278.32

v = 16.68 m/s

Therefore, the velocity with which the ball hit the ground is 16.68 m/s

When 150. g zinc sulfide are burned in excess oxygen, 68.5 g of zinc oxide are actually produced, along with sulfur dioxide. Determine the percent yield of zinc oxide after finding the theoretical production of zinc oxide.

**Show the balanced equation before you begin.**

Answers

%yield = 54.6%

Further explanation

Percent yield is the compare of the amount of product obtained from a reaction with the amount you calculated

(theoretical)

General formula:

Percent yield = (Actual yield / theoretical yield )x 100%

Reaction

2ZnS+3O₂ ⇒ 2ZnO+2SO₂

MW ZnS = 97.474 g/mol

mol ZnS

[tex]\tt \dfrac{150}{97.474}=1.54[/tex]

MW ZnO = 81.38 g/mol

mol ZnO (from mol ZnS as limiting reactant, O₂ excess)

[tex]\tt \dfrac{2}{2}\times 1.54=1.54[/tex]

Actual ZnO produced

[tex]\tt 1.54\times 81.38=125.33~g[/tex]

Theoretical production = 125.388

%yield

Explanation:

What is the factor that changes the reaction rate in the following example and why:
Wine sours more slowly when stored in closed bottles.

Answers

Answer:

The factor is called a "catalyst." The wine sours more slowly when stored in closed bottles because there's no "oxygen" inside the bottle that could lead to an increase rate of decomposition.

Explanation:

Wines are naturally stored with a cork. The cork prevents oxygen from entering into the bottle. As you probably know, wines have natural bacteria which play a role in the process of fermentation. Once bacteria are introduced to oxygen, they multiply. However, in the process of fermentation, there's no oxygen present. So, once the bottle of wine is opened, it should be consumed immediately because exposing it to air will change its flavors.

A "catalyst" is a factor that affects reaction rates. Their presence hastens the time for decomposition.

Answers

Answer::

*Gravitational potential energy transforms into thermal energy.*

O Gravitational potential energy transforms into kinetic energy.

O Gravitational potential energy transforms into thermal energy.

When a skydiver jumps out of a plane, the following energy transfers take place: the skydiver's gravitational potential energy decreases as his altitude decreases and his kinetic energy store increases as his speed increases.When a skydiver jumps out of a plane, the following energy transfers take place: the skydiver's kinetic energy store increases as their speed increases. the thermal store of the air and the skydiver increases, as there is friction between the skydiver and the air particles.

In this case, both options A and B are correct.

The water molecules are in a block of ice containing 0.750 mole of water. The number of water molecule is 4.52 x 10²³molecules.

What are molecules?

Molecules are defined as a group of two or more atoms that together create the lowest recognizable unit into which a pure material can be separated while retaining its makeup and chemical qualities.

It can also be defined as a group of two or more atoms held together by attractive forces called as chemical bonds.

There are mainly three types of molecule.

Molecules of an atomMolecules of an compoundMolecules of an element

1 mole of water molecules = 6.022 x 10²³ molecules

So, 0.750 mole of molecules = 6.022 x 10²³ x 0.750

= 4.52 x 10²³ molecules

Thus, the water molecules are in a block of ice containing 0.750 mole of water. The number of water molecule is 4.52 x 10²³molecules.

Identify the number of each jelly bean needed to make both models.

Answers

Answer:

Altogether for both models; two red jellybeans, two white jellybeans, two black jellybeans and six blue jellybeans.

Note: Since no specific color was stated for oxygen atoms, the answer assigns blue colored jellybeans to represent oxygen atoms.J

Explanation:

Sodium bicarbonate, NaHCO₃ is a compound composed of one atom of sodium, one atom of hydrogen, one atom of carbon and three atoms of oxygen.

Since red jellybeans represent sodium atoms, white jellybeans represent hydrogen atoms, black jellybeans represent carbon atoms and blue jellybeans represent oxygen atoms, each of the two students will require the following number of each jellybean for their model of sodium carbonate: One red jellybean, one white jellybean, one black jellybean and three blue jellybeans.
