How many grams of chlorine are required in order to consume 8 mol of
sodium?

The comparison of the results obtained from the experimental and the control groups validates the conclusions of the experiment.

The question is incomplete but I will, try to help you the much I can. The term experimental groups refer to the group that recieves the treatment while the control group is the group that did not receieve the treatment.

Hence, the comparison of the results obtained from the experimental and the control groups validates the conclusions of the experiment.

Explanation:

i) The equation of the dissolution of BF2 is;

BaF2(s)⇄Ba2+(aq)+2F-(aq)

ii) Ksp =[Ba2+]  [2F-]^2

iii) Let the concentration/solubility of [Ba2+] and [2F-] be x

Ksp = [x] [2x]^2

Ksp = 4x^3

iv) x =∛Ksp/4

A) Sodium and chlorine forming salt, in this reaction salt is a new product with different properties than sodium or chlorine

Therefore it is a chemical reaction

B) A candle burning to form carbon dioxide, in this reaction carbon dioxide is a new product with different properties than the candles wax

Therefore it is a chemical reaction

C) Marshmallow releasing carbon is similar to the above one

Therefore it is a chemical reaction

D) Ice turning into water, in this reaction the water can be transformed into ice by freezing it

Therefore it is not a chemical reaction

The answer to your question is D) Ice turning into water

Answer:

0.333 M

Explanation:

Divide the mass of NaOH by the molar mass and then divide by the volume.

80.0 g / 40.0 g/mol = 2.00 mol NaOH

2.00 mol NaOH / 6.00 L = 0.333 M NaOH

okay so you mean this ?

a term for disaccharides would be double sugar or boise!

monosaccharides are simple sugars soluble in water. any class of sugars like glucose.

polysaccharide is starch, cellulose, or glycogen. with molecules together. a carbohydrate.

saccharide knows as to the term structure of carbohydrates. carbohydrates are plain simple? organic compounds that are aldehyde or ketone functional group. with the general chemical formula of carbohydrates is c (H O)

n. 2. n

To solve this we must be knowing each and every concept related to monosaccharide, polysaccharide and disaccharide. Therefore, monosaccharide is the term which  describes the given sugar.

Sugar is the generic term for a variety of sweet-tasting, soluble sugars, many of which are utilized in food. Glucose, galactose, and fructose are examples of simple sugars, often known as monosaccharides.

Disaccharides comprise sugars (carbohydrate compounds) created when two simple sugars, or monosaccharides, combine to create a disaccharide.

Polysaccharides, also known as polycarbohydrates, are among the most common carbohydrates present in foods. They are polymeric long-chain carbohydrates made up of monosaccharide units linked together by glycosidic bonds.

Therefore, monosaccharide is the term which  describes the given sugar.

Answer:

806.96 g

Explanation:

From the question,

Using,

No. of mole = reacting mass/molar mass.

n = R.m/m.m....................... Equation 1

make R.m the subject of the equation

R.m = molar mass of tungsten × number of mole of tungsten.................. Equation 2

Given: number of mole of tungsten = 4.4 moles

Constant: Molar mass of tungsten = 183.8 g/mol

Substitute these values into equation 2

Therefore,

mass of tungsten = 4.4×183.4

mass of tungsten = 806.96 g

809.6g is your answer

Answer:

1 mole of tungsten =184 g

4.4 mole of tungsten =184×4.4=809.6g

Explanation:

We know that photosynthesis involves the combination of carbon dioxide and water in the presence of sunlight to yield glucose.

If the atmosphere is rich in carbon dioxide such as  in a green house where air is filled with carbon dioxide, the rate of photosynthesis is increased.

As the rate of photosynthesis is increased, the growth of plants is also increased.

Hence, in a greenhouse where the air contains more carbon dioxide, the rate of plant growth increases.

Answer:

79.14%

Explanation:

Given the equation : 2Fe2O3 + 3C 4Fe + 3C02

The theoretical yield of CO2 ; is 102.6g

Actual yield = 81.2 gram

Percentage yield = (actual yield / theoretical yield) * 100%

Percentage yield = (81.2 / 102.6) * 100%

Percentage yield = 0.7914230 * 100%

Percentage yield = 79.14%

Hence, tbe percentage yield of CO2 is 79.14%

Answer: 16.32 g of [tex]O_2[/tex] as excess reagent are left.

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} SO_2=\frac{21.71g}{64g/mol}=0.34mol[/tex]

[tex]\text{Moles of} O_2=\frac{21.71g}{32g/mol}=0.68mol[/tex]

[tex]2SO_2(g)+O_2(g)\rightarrow 2SO_3(g)[/tex]  

According to stoichiometry :

2 moles of [tex]SO_2[/tex] require = 1 mole of [tex]O_2[/tex]

Thus 0.34 moles of [tex]SO_2[/tex] will require=[tex]\frac{1}{2}\times 0.34=0.17moles[/tex]  of [tex]O_2[/tex]

Thus [tex]SO_2[/tex] is the limiting reagent as it limits the formation of product and [tex]O_2[/tex] is the excess reagent.

Moles of [tex]O_2[/tex] left = (0.68-0.17) mol = 0.51 mol

Mass of [tex]O_2=moles\times {\text {Molar mass}}=0.51moles\times 32g/mol=16.32g[/tex]

Thus 16.32 g of [tex]O_2[/tex] as excess reagent are left.
