5.00 ml of an H2SO4 solution with unknown molarity was diluted with 25.00 ml. This was tirated with 15.00ml of .1000 M NaOH to reach the equivalence point. What is the molarity of the original unknown H2SO4 solution? Also, what would the balanced chemical equation for this reaction be?

Answers

Answer:

0.1500 M

H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O

Explanation:

The balanced chemical equation is:

H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O

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

15.00 mL * 0.100 M = 1.5 mmol NaOH

Then we convert NaOH moles into H₂SO₄ moles:

1.5 mmol NaOH * [tex]\frac{1mmolH_2SO_4}{2mmolNaOH}[/tex] = 0.75 mmol H₂SO₄

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

0.75 mmol H₂SO₄ / 5.00 mL = 0.1500 M

What is the mass % of acetone in a 1.77 M solution of acetone (MM = 58.08 g/mol) in water? The density of the solution is 0.971 g/mL.

Answers

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]

Two waves were analyzed with some high-tech instrumentation. The first wave was found to have a wavelength of 3 x 10 m and the second wave had a wavelength of 3 x 10 m. Which wave would have a higher frequency? Explain​

Answers

Explanation:

The first wave was found to have a wavelength of 3 x 10⁵ m and the second wave had a wavelength of 3 x 10⁴ m

We need to find which wave have a higher frequency.

The relation between frequency and wavelength is given by :

[tex]c=f\lambda[/tex]

Let f₁ and f₂ be the frequency of wave 1 and wave 2.

[tex]f_1=\dfrac{c}{\lambda_1}\\\\f_1=\dfrac{3\times 10^8}{3\times 10^5}\\\\=1000\ Hz[/tex]

And

[tex]f_2=\dfrac{c}{\lambda_2}\\\\f_2=\dfrac{3\times 10^8}{3\times 10^4}\\\\=10000\ Hz[/tex]

Hence, the wave having less wavelength will have higher frequency. The wave having wavelength 3 x 10⁴ m will have higher frequency.

The oxidation state of nitrogen in NO changes from +2 to 0, and the oxidation state of carbon in CO changes from +2 to +4 as the reaction proceeds.
The oxidation state of nitrogen in NO changes from 0 to +2, and the oxidation state of carbon in CO changes from +4 to +2 as the reaction proceeds.

Answers

Answer:

The oxidation state of nitrogen in NO changes from +2 to 0, and the oxidation state of carbon in CO changes from +2 to +4 as the reaction proceeds.

Explanation:

In the catalytic converter, the oxidation number of nitrogen in NO changes from +2 to 0, and of carbon in CO changes from +2 to +4 as the reaction proceeds. Thus, option C is correct.

What is a catalytic converter?

The catalytic converter is a device used in vehicle exhaust to reduce the emission of toxic gas. The reaction in the device occurs to convert the nitric oxide into oxygen and nitrogen.

The redox reaction is given as,

2NO(g) + 2CO(g) → N₂(g) + 2CO₂(g)

In the reduction half of the reaction, the electrons are lost (addition of oxygen) like in carbon monoxide the oxygen is added that changes the number from +2 to +4. CO is a reducing agent that oxidized the carbon atom.

In the reduction half of the reaction, the oxygen is removed (electrons are added) and is shown by NO where the oxygen was lost to form N₂ with oxidation +2 to 0.

Therefore, option C. NO is a reducing agent that reduced nitrogen in the reaction.

Joshua wants to create something to put between a hot pot and a table, so he doesn't burn the table. He
knows he needs to choose a material that does not conduct heat well. Which material would be the best for
him to choose?
A. Wood
B. Aluminum
C. Copper
D. Glass

Answers

Copper is a good conductor of heat. This means that if you heat one end of a piece of copper, the other end will quickly reach the same temperature. Most metals are pretty good conductors; however, apart from silver, copper is the best.

Aluminum is an excellent heat and electricity conductor and in relation to its weight is almost twice as good a conductor as copper.

Glass is a very poor heat conductor. It has one of the lowest possible heat conduction a solid (without air trapped in it) can possibly have, this is mostly due to its lack of ordered crystal structure. Since it's an insulator, the electronic contribution to the thermal conductivity is very small.

Metals and stone are considered good conductors since they can speedily transfer heat, whereas materials like wood, paper, air, and cloth are poor conductors of heat. ... These include copper (92), iron (11), water (0.12), and wood (0.03).

Wood and Glass do not conduct heat well, aluminum is the best for him to choose because

aluminum conducted heat the fastest at an average of 14 seconds. ... Aluminum has the ability to absorb heat faster than copper, and when removed from the heat source, will cool faster because it is less dense than copper

What is the difference between a purine and a pyrimidine?

Answers

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.

The average speed of an oxygen molecule is 6.14 x 104 cm/sec at a certain temperature. What is the average speed of a CO2 molecule at the same temperature? (molar mass O2 = 31.9988; CO2 = 44.0098)

Answers

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

CaO + C CaC2+CO
What is the mass of CaC2 which can be produced from the reaction of excess calcium oxi
10.2 g of carbon? (Hint: Balance the equation first)​

Answers

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
