When chlorine is added to sodium bromide solution, the mixture turns brown. What type of reaction has taken place?

Answers

Answer:

A displacement reaction

Explanation:

This is because the chlorine reacts with the sodium bromide, forcing it to go brown.

I hope this helps, good luck! (✿◡‿◡)

When chlorine is added to a solution of sodium bromide (either as a gas or dissolved in water), the bromine is replaced by the chlorine.

What do you mean by Solution?

In chemistry, a solution is a homogeneous mixture of two or more compounds in their relative proportions that can be continually altered up to what is referred to as the limit of solubility.

Although the word "solution" is typically used to refer to the liquid state of matter, solutions of gases and solids are also possible.

When chlorine is added to a solution of sodium bromide (either as a gas or dissolved in water), the bromine is replaced by the chlorine. Because chlorine is more reactive than bromine, sodium bromide loses its bromine content. The mixture darkens to brown. The bromine has been displace, giving this colour of brown.

lons form when atoms gain or lose valence electrons. When an atom gains
electrons, it becomes negatively charged, and when an atom loses
electrons it becomes positively charged. Why?

Answers

Answer:

In neutral atom number of electrons (negativity charged particle) and number of proton ( positively charged particle) are equal.

When one or more electrons are lost so positive charge particle increases and cation is formed.

For example in Na 11 electrons and 11 protons are present when it loses one electrons protons are 11 and 10 electron are remaining so one positive charge is present.

Morever when an element gain electrons one negative charge increases and anion is formed. For example in Cl 17 proton and 17 electrons are present when it gain one electron 18 electrons and 17 protons are now present one negative is more so anion negative ion is formed.

In the equation CH4 + 2O2 --> 2H2O + CO2 What is the mass of CO2 produced when 35g of O2 reacts?

Answers

Answer:

24.06 g of CO₂

Explanation:

The balanced equation for the reaction is given below:

CH₄ + 2O₂ —> 2H₂O + CO₂

Next, we shall determine the mass of O₂ that reacted and the mass of CO₂ produced from the balanced equation. This can be obtained as follow:

Molar mass of O₂ = 2 × 16 = 32 g/mol

Mass of O₂ from the balanced equation = 2 × 32 = 64 g

Molar mass of CO₂ = 12 + (2×16)

= 12 + 32

= 44 g/mol

Mass of CO₂ from the balanced equation = 1 × 44 = 44 g

SUMMARY:

From the balanced equation above,

64 g of O₂ reacted to produce 44 g of CO₂.

Finally, we shall determine the mass of CO₂ produced by the reaction of 35 g of O₂. This can be obtained as follow:

From the balanced equation above,

64 g of O₂ reacted to produce 44 g of CO₂.

Therefore, 35 g of O₂ will react to produce = (35 × 44)/64 = 24.06 g of CO₂.

Thus, 24.06 g of CO₂ were produced from the reaction.

What are the states of matter and why are they relevant to you?

Answers

Three states of matter

Solids, liquids and gases are three states of matter. In solids, the particles are tightly packed together. In liquids, the particles have more movement, while in gases, they are spread out. Particles in chemistry can be atoms, ions or molecules.

It is important to understand the particle nature of matter. The particles that make up matter are not ‘small bits of solid’ or ‘small drops of liquid’ but atoms and molecules. The physical characteristics of those atoms and molecules decide its state.

Graphite has a specific heat of 0.709 J/gºC. If a 25 gram piece of graphite is cooled
by 17°C, how much energy was lost by the graphite?

Answers

Answer:

[tex]\boxed {\boxed {\sf 301.325 \ Joules }}[/tex]

Explanation:

Since we are given the mass, specific heat, and change in temperature, we should use this formula for energy:

[tex]q=mc \Delta T[/tex]

The mass of the graphite is 25 grams. Graphite's specific heat is 0.709 J/g °C. The change in temperature is 17 degrees Celsius.

[tex]m= 25 \ g \\c= 0.709 \ J/g \ \textdegree C \\\Delta T= 17 \ \textdegree C[/tex]

Substitute the values into the formula.

[tex]q= (25 \ g)( 0.709 \ J/g \ \textdegree C )( 17 \ \textdegree C)[/tex]

Multiply the first two numbers. The grams will cancel.

[tex]q= 17.725 \ J/ \textdegree C(17 \ \textdegree C)[/tex]

Multiply again. This time the degrees Celsius cancel.

[tex]q= 301.325 \ J[/tex]

The graphite loses 301.325 Joules of energy.
