Please mark brainliest

Diffusion is the name of process that , happens in liquids and solids ( Atomic diffusion ) as well although in solids it is a very slow process.ln liquids it is quicker, imagine putting a drop of dye into a bowl of clear water, after a while all the water will be colored.

Brown fumes of bromine vapour spread through the whole glass jar because of phenomenon of diffusion in the glass jar.

The gasses gases show the property of moving continuously in the air that's why Brown fumes of bromine vapour spread through the glass jar.

If the power source in a motor was to be replaced with an electrical load, and the armature was turned by hand, then what device have you made?

Answers

Answer:

This question doesnt make much sense but ill try to answer it.

A brushed DC electric motor is an internally commutated electric motor designed to be run from a direct current power source. Brushed motors were the first commercially important application of electricity. If the shaft of a DC motor is turned by an external force, the motor will act as a generator. DC Motor rotation does have to do with the voltage polarity and the direction of the current flow.

Based on your understanding of how bond types influence a material’s properties, identify each of the following compounds as being made of ionic, covalent, or metallic bonds.
ANSWER
Steel: Metalic
Propane: Covalent
Calcium chloride: ionic
Water: Covalent
Edge 2021

Answers

Answer: The given compounds are identified as being made of ionic, covalent, or metallic bonds:

Steel - Metallic bondsPropane - Covalent bondsCalcium chloride - Ionic bondsWater - Covalent bonds

Explanation:

A bond formed by transfer of electrons from one atom to another is called an ionic bond. An ionic bond is formed between a metal atom and a non-metal atom.

A bond formed by transfer of electrons from one atom to another is called a covalent bond. A covalent bond is formed between two or more non-metal atoms only.

Steel is actually an alloy of carbon and iron where there is less than 2% carbon, 1% manganese and small amounts of silicon, phosphorus, oxygen and sulphur are present.

When atoms of metals are held together then bond formed between these atoms is called metallic bond.

Hence, steel is made of metallic bond.

Chemical formula of propane is [tex]CH_{3}CH_{2}CH_{3}[/tex] as there are only non-metal atoms are present. So, sharing of electrons takes place in such atoms due to which covalent bonding will be there.

Hence, propane is made up of covalent bonds.  

Calcium chloride contains a metal and a non-metal atom. This means that electrons are being transferred from calcium atom to the chlorine atom. Hence, bond present in calcium chloride is ionic bond.

Water has chemical formula [tex]H_{2}O[/tex]. Since, non-metal atoms are present there so sharing of electrons takes place between hydrogen and oxygen atoms. Hence, covalent bond is present in water.

Thus, we can conclude that given compounds are identified as being made of ionic, covalent, or metallic bonds:

Steel - Metallic bondsPropane - Covalent bondsCalcium chloride - Ionic bondsWater - Covalent bonds

Steel: ✔ metallic

Propane: ✔ covalent

Calcium chloride: ✔ ionic

Water: ✔ covalent

Process name of water vapor to ice

Answers

Answer:

Deposition

this is the process of a substance changing its state from gas to solid. Solid to gas is known as sublimation

Please mark brainliest

Water is a liquid and its solid form is known as ice. When the water converts from the liquid phase (that is, water) to the solid phase (that is, ice), the process is known as freezing.
Water freezes at 0 degrees Celsius at standard atmospheric pressure, while it is present as liquid water between a temperature of 0 degrees Celsius and 100 degrees Celsius. Heat is lost to the surroundings as the water freezes. The ethalapy of fusion of water or heat of fusion of water is 6 kJ/mol. That is, for freezing 1 mole of water at 0 degrees Celsius, 6 kJ of heat is lost to the surroundings or is given out. Thus, freezing is an exothermic process.
Note that freezing refers to the phase change from liquid to solid and does not involve any change in the temperature of water.

Describe at least two advantages and two disadvantages of using natural gas as a source of energy.

Answers

Answer:

See explanation

Explanation:

Natural gas is mined along with crude oil in many oil wells. It has the advantage of being a cheap fossil fuels which is easily obtainable.

Generally, natural gas is the cleanest of all the fossil fuels. This means that it is the fossil fuel that least contributes to environmental pollution.

On the other hand; natural gas produces some amount of sulphur as it is burnt and mercury as particulate matter. These substances are quite dangerous to health.

Secondly, the combustion of natural gas leads to the production of the oxides of nitrogen which play a key role in the occurrence of photochemical smog.

Consider the redox reaction below talking place in certain electro chemical cell: Cu(s)+cu^2+(aq) -------> Cu^2+(aq) + Cu (s)

Answers

Answer:

cu+2 ------ oxidation whereas Cu ------ reduction.

Explanation:

In the reaction, cu+2 is the place where oxidation occurs because this cupric ion losses electrons  which causes +2 charge on it. we know that oxidation is the loss of electrons and reduction is the gaining of electrons so the Cu is the place or atom at which reduction occurs. Electrochemical cells have two electrodes, which is anode and the cathode. The anode is the electrode where oxidation occurs whereas the cathode is the electrode where reduction takes place.

How many milliliters of 1.5 M H.So, are needed to exactly
neutralize 20. milliliters of a 0.8 M KOH solution?

Answers

Answer: A volume of 10.66 mL of 1.5 M H is required to exactly neutralize 20. milliliters of a 0.8 M KOH solution.

Explanation:

Given: [tex]M_{1}[/tex] = 1.5 M,     [tex]V_{1}[/tex] = ?

[tex]V_{2}[/tex] = 20 mL,         [tex]M_{2}[/tex] = 0.8 M

Formula used to calculate the volume is as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]

Substitute the values into above formula as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}\\1.5 M \times V_{1} = 0.8 M \times 20 mL\\V_{1} = 10.66 mL[/tex]

Thus, we can conclude that a volume of 10.66 mL of 1.5 M H is required to exactly neutralize 20. milliliters of a 0.8 M KOH solution.

The copper (II) present in the wood will make the flame produce a bluish-green color.

This is because copper (II) compounds are known to produce flame colors that range from blue to bluish-green when tested in the laboratory.

how many moles of H2 are required to make 10 moles of water?​

Answers

Explanation:

10 moles h20 is required

10 moles of H₂ are required to make 10 moles of H₂O.

What is Stoichiometry ?

Stoichiometry is an important concept which helps us use the balanced chemical equation to measures the amount of reactants and products.

What is Balanced Chemical equation ?

A balanced chemical equation is chemical equation that has equal number of atoms on both sides of arrow that is reactant and product.

First we have to write the Balanced chemical equation

2H₂ + O₂ → 2H₂O

To produce 2 moles of water, 2 moles of hydrogen are required to produce 10 moles of water.

So,

[tex]\frac{2\ \text{moles of}\ H_2}{2\ \text{moles of}\ H_2O}[/tex] × 10 moles of H₂O

= 10 moles of hydrogen are required.

Thus, from above conclusion we can say that 10 moles of H₂ are required to make 10 moles of H₂O.

Let's start by figuring out the amount in miles. From there, we can easily find the equivalent mass. Which equation do we need to find out how many moles of NH4Cl would there be in 500 mL of a 0.300 M solution of it?

A. n=C x V
B. C=V x n
C. C=n x V
D. n=C / V

Answers

Answer:

A. n= C x V

Explanation:

Molarity of a solution is the molar concentration of that solution. It can be calculated using the formula:

M = n/V

Where;

M = molarity (M)

n = number of moles (n)

V = volume (mL)

To calculate the number of moles from a given molarity value and volume, we say:

n = M × V

For this case of NH4Cl;

V = 500mL = 500/1000 = 0.5L

M = 0.300 M

n = 0.300 × 0.5

n = 0.15moles

Answer: n=CxV
