How much heat is required to raise the temperature of a 6.21 g sample of iron from 25.0 oC to 79.8 oC?

Answers

Answer:

151.1J

Explanation:

Given parameters:

Mass of iron  = 6.21g

Initial temperature of iron  = 25°C

Final temperature of iron  = 79.8°C

Unknown:

Amount of heat = ?

Solution:

The amount of heat require to cause this temperature can be determined using the expression below;

    H  = m c (T₂ - T₁)

H is the amount of heat

m is the mass

c is the specific heat capacity

T is the temperature

    Specific heat capacity of iron 0.444J/g°C

Insert the parameters and solve;

     H  = 6.21 x 0.444 x (79.8 - 25)

     H   = 151.1J

In your own words, please explain how to name acids.

Answers

Answer:

Acids are named based on their anion — the ion attached to the hydrogen. In simple binary acids, one ion is attached to hydrogen. Names for such acids consist of the prefix “hydro-“, the first syllable of the anion, and the suffix “-ic”. Complex acid compounds have oxygen in them.



2. What properties do all acids have?

3. Why should you never use taste as a method for testing an unknown substance?

4. What is used to detect the presence of acids?

3. You should NEVER taste unknown chemicals because many are poisonous and can destroy body tissue.

4. Most often dyes are used to detect acids. The dyes will turn a certain color which indicates the presence of an acid.

10. You can use litmus to detect wether a solution is a base or an acid.

11. The most common bases I can think of would be: baking soda, laundry detergent, or soaps.

12. Antacids work by neutralizing the acids in your stomach.

13. When an acid and base are mixed together, they produce a salt.

14. Normally pH meters are used, but you can also calculate the pH using math. (yuck)

15. The pH scale measures how acidic or basic a substance is. It ranges from 0-14, with 7 being neutral.

17. pH is very important to the environment as it helps us measure and monitor for safe water conditions. A rise or fall from the average water pH level can indicate chemical pollution.

18. Salt is formed when an acid and base react with each other. It then has a cation of the base, and anion of the acid.

Which models of the atom does the experimental evidence from Bohr's hydrogen experiment support? Explain why these models are compatible with the experimental results.

The models are Daltons, Thompsons, and Rutherfords

Answers

Answer:

Rutherfords

Explanation:

The model of the atom supported by Bohr's hydrogen experiment is the Rutherford's model of the atom.

Rutherford through his experiment on gold foil suggested the atomic model of the atom. The model posits that an atom has a small positively charged center(nucleus) where nearly all the mass is concentrated.

Surrounding the nucleus is the large space containing electrons. In the Bohr's model of the atom, he suggested that the extranuclear space of the atom is made up of electrons in specific spherical orbits around the nucleus.

Answers

As the police car moves towards them, the pitch of the police car's siren goes up because the sound waves get closer together in front of the police car. When the police car moves away from the person, the pitch goes down because the waves spread out behind the police and that makes the frequency go down.

Calculate how much Carbon Dioxide IN GRAMS needs to be absorbed to
release 500g of oxygen during photosynthesis.

Answers

Answer:

687.5 g of CO2

Explanation:

We'll begin by writing the balanced equation for photosynthesis. This is illustrated below:

6CO2 + 6H2O —> C6H12O6 + 6O2

Next, we shall determine the mass of CO2 absorbed and the mass of O2 released from the balanced equation. This is illustrated below:

Mass of CO2 = 12 + (2 × 16) = 12 + 32

= 44 g/mol

Mass of CO2 from the balanced equation = 6 × 44 = 264 g

Molar mass of O2 = 2 × 16 = 32 g/mol

Mass of O2 from the balanced equation = 6 × 32 = 192 g

Summary:

From the balanced equation above,

264 g of CO2 were absorbed to release 192 g of O2.

Finally, we shall determine the mass of CO2 absorbed to release 500 g of O2. This can be obtained as follow:

From the balanced equation above,

264 g of CO2 were absorbed to release 192 g of O2.

Therefore, Xg of CO2 will be absorbed to release 500 g of O2 i.e

Xg of CO2 = (264 × 500)/192

Xg of CO2 = 687.5 g

Thus, 687.5 g of CO2 will be absorbed to release 500 g of O2.

How many moles of NaCl could be found in 0.4 L of a 0.9 M solution? Round your answer to
two decimal places.

Answers

Answer:

0.36mol

Explanation:

Given parameters:

Volume of NaCl  = 0.4L

Molarity  = 0.9M

Unknown:

Number of moles  = ?

Solution:

To find the number of moles, the molarity of a solution is the amount of solute contained in a solution.

 Molarity  = [tex]\frac{number of moles}{volume}[/tex]  

 Number of moles = molarity x volume

 Insert the parameters and solve;

 Number of moles = 0.4 x 0.9  = 0.36mol

10 g of copper is heated and the mass increases to 12.5 g. What is the mass of the copper in the new substances?

Answers

Answer:

10g

Explanation:

The amount of copper in the heated mass of the new substance produced is still 10g because in any chemical action, mass is always conserved.

According to the law of conservation of matter "matter is neither created nor destroyed in a chemical reaction". The change in mass is only due to oxygen gas that combines with the new copper formed or other substances that joined the mass. The substance will still have the same amount of copper as the original one. Since we started with 10g of copper, we end with 10g of copper.

Answers

If you mark those points on the phase diagram it appears to be moving from vapor to liquid. If you can’t see how I determined that please let me know and I can further explain.

Vapor to liquid is the same as saying gas to liquid, which I believe to be the correct answer.

Answer:

[OH⁻] = 8.91x10⁻¹²M

Explanation:

In aqueous solutions, the [OH] and [H⁺] are associated in the equation of hydrolisis of water:

1x10⁻¹⁴ = [OH⁻] [H⁺]

With pH, we can solve for [H⁺] and obtain, the [OH⁻] using this equation:

pH = -log [H⁺]

[H⁺]= 10^-pH

[H⁺] = 1.122x10⁻³M

1x10⁻¹⁴ = [OH⁻] [1.122x10⁻³M]

[OH⁻] = 8.91x10⁻¹²M
