Write a complete, balanced chemical equation where tin metal reacts with aqueous hydrochloric acid to produce tin(II) chloride and hydrogen gas. Include states.

From the equation, which element is oxidized, and which element is reduced?

Answers

Answer:

1. The balanced equation is given below:

Sn (s) + 2HCl (aq) –> SnCl₂ (aq) + H₂ (g)

2a. H is oxidized.

2b. Sn is reduced.

Explanation:

1. Balanced equation for the reaction between tin (Sn) metal and aqueous hydrochloric acid (HCl) to produce tin(II) chloride (SnCl₂) and hydrogen gas (H₂).

This is illustrated below:

Sn (s) + HCl (aq) –> SnCl₂ (aq) + H₂ (g)

There are 2 atoms of Cl on the right side and 1 atom on the left side. It can be balance by putting 2 in front of HCl as shown below:

Sn (s) + 2HCl (aq) –> SnCl₂ (aq) + H₂ (g)

Now, the equation is balanced

2. Determination of the element that is oxidize and reduced.

This can be obtained as follow:

We shall determine the change in oxidation number of each element.

NOTE:

a. The oxidation number of H is always +1 except in hydrides where it is –1.

b. The oxidation state of Cl is always –1.

Sn (s) + 2HCl (aq) –> SnCl₂ (aq) + H₂ (g)

For Tin (Sn):

Sn = 0

SnCl₂ = 0

Sn + 2Cl = 0

Cl = – 1

Sn + 2(–1) = 0

Sn – 2 = 0

Collect like terms

Sn = 0 + 2

Sn = +2

Therefore, the oxidation number of Tin (Sn) changes from 0 to +2

For H:

H = +1

H₂ = 0

The oxidation number of H changes from +1 to 0

For Cl:

Cl is always –1. Therefore no change.

Summary:

Element >>Change in oxidation number

Sn >>>>>>>From 0 to +2

H >>>>>>>>From +1 to 0

Cl >>>>>>>No change

Therefore,

Sn is reduced since its oxidation number increased from 0 to +2.

H is oxidized since it oxidation number reduced from +1 to 0

The balanced chemical equation for the reaction is

Sn(s) + 2HCl(aq) → SnCl₂(aq) + H₂(g)

and the element that oxidized is tin (Sn) while the element that is reduced is hydrogen (H)

The balanced chemical equation for the reaction where tin metal reacts with aqueous hydrochloric acid to produce tin(II) chloride and hydrogen gas is

Sn(s) + 2HCl(aq) → SnCl₂(aq) + H₂(g)

From the equation,

The element that is oxidized is tin (Sn), because the oxidation state of Sn increased from 0 to +2

The element that is reduced is hydrogen (H), because the oxidation state of H decreased from +1 to 0.

Hence,

The balanced chemical equation for the reaction is

Sn(s) + 2HCl(aq) → SnCl₂(aq) + H₂(g)

and the element that oxidized is tin (Sn) while the element that is reduced is hydrogen (H).

What are different states of matter?

The matter is anything that has mass and occupies space.

Matter can exist in four different states: solid, liquid, gas, and plasma.

By examining the arrangement of molecules, it is possible to comprehend the characteristics of the many forms of matter.

The state of a solid turns to a liquid when it is heated past its melting point.

A liquid turns into a gas when it is heated past the point at which it vaporizes.

Solids have a distinct shape and dimension and are densely packed.

Liquids fill the container's space and are loosely packed.

Gas has a large intermolecular distance and is not stiff.

When energy is removed from the particles of a liquid, the speed gets slowed, and so the motion decreases, as the motion is limited they become packed and the distance between them decreases, and the intermolecular forces increases.

Describe how calcium and fluorine bond together to form calcium fluoride. The electron arrangement of each atom is shown.

Answers

Answer:

Detail is given below.

Explanation:

Calcium is alkaline earth metal. It has two valance electron. Thus calcium needs six more electron to complete the octet. Thus, its very easy for calcium to remove its two electron and get complete octet.

Electronic configuration of Ca:

Ca₂₀ = [Ar] 4s²

While,

Fluorine is halogen. It has seven valance electrons. It needed only one electron to complete the octet. When it combine with calcium , calcium loses two electrons thus two atom of fluorine combine with one atom of fluorine and stable compound calcium fluoride is formed.

Electronic configuration of F:

F₉  = [He] 2s² 2p⁵

Chemical equation:

Ca  + F₂     →     CaF₂

C. Thomson discovered that atoms of one kind of element could

D. Thomson discovered that the atom contained smaller particles

Answers

Answer:

D. thomson discovered that the atom contains smaller particles called electrons

Thomson discovered that the atom contained smaller particles called electrons. The correct option is D.

What is Dalton's atomic model?

Dalton proposed that all matter is composed of tiny indivisible particles known as atoms, which he envisioned as "solid, massy, hard, impenetrable, movable particle(s)."

Thomson's experiment altered Dalton's atomic model by revealing the existence of smaller particles known as electrons within the atom.

The first part of his theory states that all matter is made up of indivisible atoms. According to the second part of the theory, all atoms of a given element have the same mass and properties.

One of Dalton's most important contributions is that it does not violate several fundamental laws of chemical combination, including the law of definite proportions, the law of multiple proportions, and the law of conservation of mass.

Thus, the correct option is D.

You are about to take a short trip. However, you will not be traveling by car or bus; instead you will be traveling up in a hot air balloon. You know that hot air balloons, like the ones pictured, are able to rise when the air contained in them is heated. Why does the balloon rise? What is happening at the molecular level to make the balloon rise?

Answers

Answer:

Hot air rises. Heated air molecules “spread out” or expand and bounce around, and the space becomes less dense than the surrounding space. Increasing the air temperature inside the balloon envelope makes it less dense than the air, thus making it “lighter than air”.

Explanation:

I'm new to brainly but I hope this helped!

Balloon rise because  Warm air ascends. Heat causes the molecules of the air to "spread out," or expand, and bounce off one another, making the area less dense than the surroundings.

What are molecules ?

A molecule is the smallest unit of a substance that keeps its content and properties. It is made up of two or more atoms that are joined together by chemical bonds.

Chemistry is built on molecules. The element symbol and a subscript indicating the number of atoms are used to identify molecules.

Calculate the molarity of a NaOH solution that is prepared by diluting 100mL of 0.20M NaOH with 150mL of H2O.

M = Molarity  

n = number of moles of solute

This story that is related to the movement of water in relation to the amount of solute seeks to explain the process of OSMOSIS in a very interesting way.

Explanation:

The OSMOSIS process is a process where water diffuses from a compartment with fewer solutes to one with higher solutes, that is why the osmotic intention is to balance the concentrations and molarities between both compartments, this is called osmotic balance.

For this to happen, a highly water-permeable barrier is needed.

What is the wavelength of a radio wave with a frequency of 1.2 × 106 Hz? 3.6 × 1014 meters 3.6 × 102 meters 2.5 × 102 meters

Answers

Answer:

2.5 × 102 meters

Explanation:

Wavelength, which is denoted by λ, can be calculated using the formula:

λ = v/f

Where λ = wavelength (m)

v = speed of light (3×10^8m/s)

f = frequency (Hz)

According to the given information I n the question, f = 1.2 × 10^6 Hz, v = 3×10^8m/s

Hence;

λ = v/f

λ = 3 × 10^8 ÷ 1.2 × 106

λ = 3/1.2 × 10^ (8-6)

λ = 2.5 × 10^2

Therefore, the wavelength of the radio wave is 2.5 × 10^2 meters
