What is the product of the reaction?

Please answer with the correct answer! Thanks.

Answer:

D) Fe³⁺, O²⁻; Fe₂O₃

Explanation:

Option D shows correctly an ion pair and the correct formula for the ionic compound the two ions form.

Ion pairs of iron and oxygen react to form iron (III) oxide. The iron (III) oxide is one of the oxides of iron. The compound is usually attacked by acids and it is often called rust. It is used in the feedstock of the steel and iron industries. This means that the compound is used in the production of iron, steel, and many alloys.

Below are some equations:

4 Fe + 3 O₂→ 2 Fe₂O₃

Fe⁰ + 3O₂⁰ →  Fe³⁺O₃²⁻

Answer:

There are 6 hydrogen atoms.

Explanation:

The formula for an alkyne that has only one triple bond is as follows:

Where n is any natural number greater than 2.

For this problem, n=4. This would mean the formula is:

Thus

Thus the answer is 6, there are 6 hydrogen atoms.

Answer:

[tex]\%m/m=10.6\%[/tex]

Explanation:

Hello!

In this case, since the by-mass percent is defined by:

[tex]\%m/m=\frac{m_{solute}}{m_{solution}} *100\%[/tex]

Thus, since the given 1.77 M solution is given in terms of mol/L, we need to compute the mass of acetone via its molar mass and the volume of solution in L to g via the density:

[tex]\%m/m=1.77\frac{mol}{L}*\frac{58.08g}{1mol}*\frac{1L}{1000mL}*\frac{1mL}{0.971g} *100\%\\\\\%m/m=10.6\%[/tex]

Answer:

18.1 g

Explanation:

Step 1: Write the balanced equation

CaO + 3 C ⇒ CaC₂ + CO

Step 2: Calculate the moles corresponding to 10.2 g of C

The molar mass of C is 12.01 g/mol.

10.2 g × 1 mol/12.01 g = 0.849 mol

Step 3: Calculate the moles of CaC₂ produced from 0.849 moles of C

The molar ratio of C to CaC₂ is 3:1. The moles of CaC₂ produced are 1/3 × 0.849 mol = 0.283 mol

Step 4: Calculate the mass corresponding to 0.283 moles of CaC₂

The molar mass of CaC₂ is 64.10 g/mol.

0.283 mol × 64.10 g/mol = 18.1 g

Answer: mass of chlorine reacted is 3.18 g

Explanation:

2 K + Cl2 = 2KCl

no. of moles of K = mass / molar mass

= 3.50 / 39

= 0.0897

no. of moles of KCl = mass / molar mass

= 6.67 / 74.5

= 0.0895  

no. of moles of Cl2 required = number of moles of KCl / 2

= 0.0895 / 2

= 0.0448 moles  

mass of Cl2 required = no. of moles of Cl2 required x molar mass

= 0.0448 x 71

= 3.1808 g ≈ 3.18 g

Therefore mass of chlorine reacted is 3.18 g

Answer:

Their melting and boiling points of alkanes are relatively low. The higher the molecular weight (the greater the number of carbons), the higher the boiling point.

Answer:

0.1500 M

H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O

Explanation:

The balanced chemical equation is:

First we calculate how many NaOH moles reacted, using the volume and concentration:

Then we convert NaOH moles into H₂SO₄ moles:

This amount of H₂SO₄ moles was originally contained within 5.00 mL of solution, thus the molarity is:

Answer: Adenine and guanine are the two purines and cytosine, thymine and uracil are the three pyrimidines. The main difference between purines and pyrimidines is that purines contain a sixmembered nitrogencontaining ring fused to an imidazole ring whereas pyrimidines contain only a sixmembered nitrogencontaining ring. They both are types or categories of nitrogen containing bases present in nuclei acids of DNA and RNA.

Purines are 2 Ring or Carbon Ring, Nitrogen containing bases. That consist of these 2 rings next placed next to each other. These examples include - Adenine and Guanine.

Pyrimidines are 1 or single Ring Nitrogen containing structures. There are 3 nitrogenous bases that are categorized as pyrimidines. Cytosine, Thymine, and Uracil.

I believe the answer is A. Organic.

Hope it helps!

Answer:

Organic

Explanation:

living things are organic, so chemical is wrong, detrital is when rocks form from broken down rocks left behind, again not from living things so that's also wrong, that leave Organic and foliated, foliated makes no sense which leave only Organic, so organic will be your answer

Answer:

the type is single replacement

The given reaction equation represents a single-replacement reaction.

Explanation:

                   ABC→ A+B+C

                   A+B+C → ABC

                   AB+ C → AC + B

                  AB+ CD → AC + BD

Given:

[tex]Fe + CuCl_2 \rightarrow FeCl_2 + Cu[/tex]

To find:

The type of chemical reaction represented by the given equation.

Solution:

In the given reaction:

[tex]Fe + CuCl_2 \rightarrow FeCl_2 + Cu[/tex]

Iron is replacing copper from its compound which is copper(II) chloride to give iron(II) chloride and copper as a product.

So from this, we can conclude that the given reaction equation represents a single-replacement reaction.

Answer:

the average speed of [tex]V_{av} CO_2[/tex] is 5.24 ×  104 cm/s

Explanation:

The computation of the average speed of a [tex]CO_2[/tex] is as follows:

[tex]\sqrt{average} = \sqrt{\frac{8 RT}{\pi M} }[/tex]

where,

M = Molar mass

[tex]V_{av} = \frac{\sqrt{1}}{M}[/tex]

Given that

[tex]V_{av} \ of\ oxygen= 6.14 \times 10^4 cm/s[/tex]

The molar mass of oxygen i.e. (MO_2) = 31.9988 g/mol

And, the molar mass of CO_2 is  44.0098 g/mol

Now

[tex]\frac{V_{av} CO_2}{V_{av} O_2} = \frac{\sqrt{M_{O2} }}{M_{CO2}}[/tex]

Now place these values to the above formula

[tex]\frac{V_{av}CO_2}{6.14\times 104 cm/s} = \frac{\sqrt{31.9988} }{44.0098}[/tex]

So,

V_av CO_2 is 5.24 ×  104 cm/s

hence, the average speed of [tex]V_{av} CO_2[/tex] is 5.24 ×  104 cm/s
