The balanced equation  of reaction  between iron and sulfur to yield  sulfide is as below

8 Fe(s) + S8(s)→ 8 FeS (s)


 <u><em>Explanation</em></u>

 According  to the  law of mass  conservation , the  number   of  atoms  in the  reactant side  must be equal  to  number  of atoms in  product  side

.

By  putting   coefficient  8 in front  of Fe   and in front  of FeS ,  it   balance the reaction  of synthesis of FeS   since it make sure the number  of  atoms  are equal in both side.

for example   there are 8 atoms  of Fe in reactant  side and  8 atoms of Fe in the product side.

Glucose is an example of which carbon-based macromolecule?
Blababa [14]

Answer: Glucose is an example of carbon-based macromolecule known as carbohydrates

Explanation:

carbon based macromolecule are important cellular components and they perform a variety of functions necessary for growth and development of living organisms. There are 4 major types of carbon based molecules and these includes;

Carbohydrate

Lipids

Proteins and

Nucleic acids.

Carbon is the primary components of these macromolecules. Carbohydrate macromolecules are made up of monosaccharide, disaccharide and polysaccharides. Glucose is an example of a monosaccharide and it has two important types of functional groups: a carbonyl group and a hydroxyl group. I hope this helps. Thanks

Why reaction between phosphorus and oxygen produces four atoms of phosphorus and five atoms of oxygen
andreev551 [17]

Answer:

Reaction between an oxygen and  a phosphorus will produce oxides of phosphorus.

Explanation:

Reaction between oxygen and phosphorus produces four atoms of phosphorus with five atoms of oxygen. Sometimes it produces two atoms of phosphorus and five atoms of oxygen and sometimes four atoms of phosphorus and six atoms of oxygen. It does so depending upon the availability of oxygen. The size of phosphorus atom  interferes with the ability to form a double bonds to the other elements, such as nitrogen, oxygen, etc.

Consider the reaction of magnesium metal with hydrochloric acid to produce magnesium chloride and hydrogen gas. if 4.40 mol of m
Georgia [21]
The balanced chemical equation for the above reaction is as follows ;
Mg + 2HCl —> MgCl2 + H2
The stoichiometry of Mg to HCl is 1:2
This means that 1 mol of Mg reacts with 2 mol of HCl
Equal amounts of both Mg and HCl have been added. One reagent is the limiting reactant and other reactant is in excess.
Limiting reactant is the reagent that is fully used up in the reaction and the amount of Product formed depends on the amount of limiting reactant present.
In this reaction if Mg is the limiting reactant, 4.40 moles of Mg should react with 4.40x2 -8.80 moles of HCl.
But only 4.40 moles of HCl present therefore HCl is the limiting reactant that reacts with 4.40/2 = 2.20 moles of Mg
Stoichiometry of HCl to MgCl2 is 2:1
Since HCl moles reacted -4.40 mol
Then MgCl2 moles formed are 4.40/2 = 2.20 mol of MgCl2

It takes 24.56 mL of a sodium hydroxide solution to precisely neutralize 2.023 g of potassium hydrogen phthalate (F.W. = 204.22g
Alinara [238K]

Answer:

0.4033 M is the concentration of the sodium hydroxide solution.

Explanation:

Mass of potassium hydrogen phthalate = 2.023 g

Molar mass of potassium hydrogen phthalate = 204.22 g/mol

Moles of potassium hydrogen phthalate :

= \frac{2.023 g}{204.22 g/mol}=0.009906 mol

C_8H_5KO_4+NaOH\rightarrow C_8H_4KO_4Na+H_2O

According to reaction, 1 mole of potassium hydrogen phthalate reacts with 1mole of NaOH. Then 0.009906 moles of potassium hydrogen phthalate  will recat with:

\frac{1}{1}\times 0.009906 mol=0.009906 mol of NaOH

Moles of NaOH = 0.009906 mol

Volume of NaOH solution = 24.56 mL = 0.02456 L

Molarity=\frac{Moles}{Volume (L)}

[NaOH]=\frac{0.009906 mol}{0.02456 L}=0.4033 M

0.4033 M is the concentration of the sodium hydroxide solution.
