what is the difference between a diatomic element and a compound

Answers

Answer 1

Diatomic

consist of two atoms bonded together. In contrast, monatomic elements consist of single atoms (e.g., Ar, He). Many compounds are diatomic, such as HCl, NaCl, and KBr. Diatomic compounds consist of two different elements. There are seven pure elements that form diatomic molecules.

Key Takeaways: Diatomic Elements

Diatomic elements are pure elements that form molecules consisting of two atoms bonded together.

There are seven diatomic elements: hydrogen, nitrogen, oxygen, fluorine, chlorine, iodine, bromine.

These elements can exist in pure form in other arrangements. For example, oxygen can exist as the triatomic molecule, ozone.

This is a list of the seven diatomic elements. The seven diatomic elements are:

Hydrogen (H2)

Nitrogen (N2)

Oxygen (O2)

Fluorine (F2)

Chlorine (Cl2)

Iodine (I2)

Bromine (Br2)

All of these elements are nonmetals, since the halogens are a special type of nonmetallic element. Bromine is a liquid at room temperature, while the other elements all gases under ordinary conditions. As the temperature is lowered or pressure is increased, the other elements become diatomic liquids.

Astatine (atomic number 85, symbol At) and tennessine (atomic number 117, symbol Ts) are also in the halogen group and may form diatomic molecules. However, some scientists predict tennessine may behave more like a noble gas.

While only these seven elements routinely form diatomic molecules, other elements can form them. However, diatomic molecules formed by other elements are not very stable, so their bonds are easily broken.

compounds

are formed by the chemical combination of two or more element. example water is a compound because two elements water and hydrogen come to form it.

If the reaction occurs between Fe2S3(s) and H+ (aq) and the equation is properly balanced with the smallest
whole-number coefficients, what is the sum of the coefficients for all reactants and products?
Fe2S3(s) + H+ (aq)

Answers

The sum of the coefficients for all reactants and products is: 12.

Here, we first need to balance the equation of the reaction between Fe2S3(s) and H+.

The chemical equation yields H2S and Fe3+ as follows;

Fe2S3(s) + H+ (aq) ------> H2S + Fe3+(aq)

Balancing the equation consequently yields;

Fe2S3(s) + 6H+ (aq) ------> 3H2S + 2Fe3+(aq)

The sum of the coefficients for all reactants and products is therefore;

Sum = 1 + 6 + 3 + 2.

Sum of coefficients = 12

An excess of sodium carbonate, Na, CO3, in solution is added to a solution containing 17.87 g CaCl2. After performing the
experiment, 13.19 g of calcium carbonate, CaCO3, is produced. Calculate the percent yield of this reaction.

Answers

Answer:

Approximately [tex]81.84\%[/tex].

Explanation:

Balanced equation for this reaction:

[tex]{\rm Na_{2}CO_{3}}\, (aq) + {\rm CaCl_{2}} \, (aq) \to 2\; {\rm NaCl}\, (aq) + {\rm CaCO_{3}}\, (s)[/tex].

Look up the relative atomic mass of elements in the limiting reactant, [tex]\rm CaCl_{2}[/tex], as well as those in the product of interest, [tex]\rm CaCO_{3}[/tex]:

[tex]\rm Ca[/tex]: [tex]40.078[/tex].[tex]\rm Cl[/tex]: [tex]35.45[/tex].[tex]\rm C[/tex]: [tex]12.011[/tex].[tex]\rm O[/tex]: [tex]15.999[/tex].

Calculate the formula mass for both the limiting reactant and the product of interest:

[tex]\begin{aligned}& M({\rm CaCl_{2}}) \\ &= (40.078 + 2 \times 35.45)\; {\rm g \cdot mol^{-1}} \\ &= 110.978\; \rm g \cdot mol^{-1}\end{aligned}[/tex].

[tex]\begin{aligned}& M({\rm CaCO_{3}}) \\ &= (40.078 + 12.011 + 3 \times 15.999)\; {\rm g \cdot mol^{-1}} \\ &= 100.086\; \rm g \cdot mol^{-1}\end{aligned}[/tex].

Calculate the quantity of the limiting reactant ([tex]\rm CaCl_{2}[/tex]) available to this reaction:

[tex]\begin{aligned}n({\rm CaCl_{2}) &= \frac{m({\rm {CaCl_{2}})}}{M({\rm CaCl_{2}})} \\ &= \frac{17.87\; \rm g}{110.978\; \rm g \cdot mol^{-1}} \\ &\approx 0.161023\; \rm mol \end{aligned}[/tex].

Refer to the balanced equation for this reaction. The coefficients of the limiting reactant ([tex]\rm CaCl_{2}[/tex]) and the product ([tex]{\rm CaCO_{3}}[/tex]) are both [tex]1[/tex]. Thus:

[tex]\displaystyle \frac{n({\rm CaCO_{3}})}{n({\rm CaCl_{2}})} = 1[/tex].

In other words, for every [tex]1\; \rm mol[/tex] of [tex]\rm CaCl_{2}[/tex] formula units that are consumed, [tex]1\; \rm mol\![/tex] of [tex]\rm CaCO_{3}[/tex] formula units would (in theory) be produced. Thus, calculate the theoretical yield of [tex]\rm CaCO_{3}\![/tex] in this experiment:

[tex]\begin{aligned} & n(\text{${\rm CaCO_{3}}$, theoretical}) \\ =\; & n({\rm CaCl_{2}}) \cdot \frac{n({\rm CaCO_{3}})}{n({\rm CaCl_{2}})} \\ \approx \; & 0.161023\; {\rm mol} \times 1 \\ =\; & 0.161023\; \rm mol\end{aligned}[/tex].

Calculate the theoretical yield of this experiment in terms of the mass of [tex]\rm CaCO_{3}[/tex] expected to be produced:

[tex]\begin{aligned} & m(\text{${\rm CaCO_{3}}$, theoretical}) \\ = \; & n(\text{${\rm CaCO_{3}}$, theoretical}) \cdot M(({\rm CaCO_{3}}) \\ \approx \; & 0.161023\; {\rm mol} \times 100.086\; {\rm g \cdot mol^{-1}} \\ \approx \; & 16.1161\; \rm g \end{aligned}[/tex].

Given that the actual yield in this question (in terms of the mass of [tex]\rm CaCO_{3}[/tex]) is [tex]13.19\; \rm g[/tex], calculate the percentage yield of this experiment:

[tex]\begin{aligned} & \text{percentage yield} \\ =\; & \frac{\text{actual yield}}{\text{theoretical yield}} \times 100\% \\ \approx \; & \frac{13.19\; {\rm g}}{16.1161\; {\rm g}} \times 100\% \\ \approx \; & 81.84\%\end{aligned}[/tex].

how many millilters of a 6.00 M sulfuric acid solution are reqired if you need 0.750 moles of H2SO4 for a reaction

Answers

125 milliliters of a 6.00 M sulfuric acid solution are required if 0.750 moles of H2SO4 are needed for a reaction.

HOW TO CALCULATE VOLUME:

The volume of a solution can be calculated by dividing the number of moles of that solution by its molar concentration. That is:

Volume = no. of moles ÷ molarity

According to this question, the molarity is given as 6.00 M sulfuric acid solution and the no. of moles is 0.75 moles. The volume is calculated thus:

Volume = 0.75mol ÷ 6M

Volume = 0.125L

Volume of sulfuric acid in milliliters = 0.125 × 1000 = 125mL

Therefore, 125 milliliters of a 6.00 M sulfuric acid solution are required if 0.750 moles of H2SO4 are needed for a reaction.

The element is Oxygen (O) in the given element model.

The atomic number of an element is equal to the number of protons in its nucleus. Since the element in question has 8 protons, its atomic number is 8. Oxygen has an atomic number of 8, making it the element with 8 protons. Additionally, the atomic number determines the identity of an element; no other element has 8 protons in its nucleus.

The element's name is Oxygen, and its chemical symbol is O. Oxygen is a vital element in the Earth's atmosphere and is essential for supporting life. It is commonly found in the form of diatomic molecules (O2), which make up a significant portion of the air we breathe. Oxygen plays a crucial role in various biochemical and chemical processes, and its presence is essential for the respiration of most living organisms.
