A chemist is using a solution of hno3 that has a ph of 3.75. what is [h ] for the solution?

Answers

A chemist is using a solution of HNO₃ that has a pH of 3.75. what is [H⁺] for the solution is 1.7 × 10⁻⁴M.

How do we calculate the [H⁺]?

Concentration of H⁺ ion will be calculated by using the below equation of pH as:

pH = -log[H⁺]

or [H⁺] = [tex]10^{-pH}[/tex]

Given that, pH = 3.75

So concentration of H⁺ ion will be calculated as:

[H⁺] = [tex]10^{-3.75}[/tex]

[H⁺] = 1.7 × 10⁻⁴M

Hence concentration of H⁺ ion is 1.7 × 10⁻⁴M.

carbon monoxide reacts with iron (ii, iii) oxide (fe3o4) making iron and carbon dioxide. when a student performed the experiment she reacted 70.0 g of fe3o4 with 70.0 g of co and the actual yield of iron was 41.9. calculate the percentage yield.
Please help me!

Answers

The percent yiled shows the extent of conversion of reactants to products. The percent yiled here is 83.1%.

Percent yield

The percent yiled in a reaction is calculated as te ratio of the actual yield to the theoretical yiled multiplied by 100.

Hence the balanced reaction equation is; Fe3O4 + 4CO → 3Fe + 4CO2.

Number of moles of Fe3O4  =  70.0 g/232 g/mol = 0.3 moles

Number of moles of CO = 70.0 g/28 g/mol = 2.5 moles

If 1 mole of Fe3O4  reacts with 4 moles of CO

x moles of Fe3O4 reacts with 2.5 moles of CO

x = 0.6 moles

Hence, Fe3O4  is the limiting reactant.

Now;

1 mole of Fe3O4 yileds 3 moles of Fe

0.3 moles of Fe3O4 yileds 0.3 moles * 3 moles/1 mole = 0.9 moles

Mass of Fe produced = 0.9 moles  * 56 g/mol = 50.4 g

Percent yield = 41.9 g/ 50.4 g * 100/1 = 83.1%

Write a two to four sentence conclusion statement explaining how the potential energy diagram is used to identify if the reaction is endothermic or exothermic, if heat was released or absorbed, and why the sign of enthalpy change was positive of negative. There should be a conclusion statement for each graph.

Answers

Answer:

The Heat of a reaction is given as the heat content/heat of formation/enthalpies of the products minus the heat content/heat of formation/enthalpies of the reactants. If the potential energy diagram has the product(s) having a higher potential energy than the reactant(s), then the reaction is an endothermic reaction (this is why the reaction absorbs heat from the surroundings to try to make up for the lack of potential energy of the reactants) and the sign on the enthalpy change is visibly positive since H(products) > H(reactants) If the potential energy diagram has the reactant(s) having a higher potential energy than the product(s), then the reaction is an exothermic reaction (this is why the reaction releases heat to the surroundings to try to take care of the higher potential energy of the reactants) and the sign on the enthalpy change is visibly negative since H(reactants) > H(products).

The correct answer is A and D.

Explanation:

Please I want brainliest.

Reason:

The size of the ions follows the order:

Negatively charged ion > Neutral atom >

Positively charged ion

This is because of the size of ions increases when the electrons are added to the outermost shell of an atom.

This happens due to the increase in

electron-electron repulsion.

Moreover, when the electrons are removed from an atom, then the affective nuclear charge that is experienced by the outermost electron increases.

Thus the size of the positively charged ion is least.

A set of atoms with the same atomic number but differing masses is known as an element's isotope. This indicates that the number of protons in each atomic nucleus and the number of electrons in the electron cloud of each isotope of an element is the same.

Some isotopes experience radioactive decay because of their unstable atomic nucleus. These isotopes are known as radioisotopes (or radionuclides) because they are radioactive by nature.

Along the slanting, horizontal line there are five dots labeled from left to right as 1, 2, 3, 4, and 5. There is one vertical line between each of the consecutive five dots. The lines are labeled from left to right as Perch, Frog, Pigeon, Rats, and Human. A text box below the branching tree diagram is labeled Derived Shared Characteristics.

From the text box, select a shared derived characteristic that humans and rats have. Explain why you think humans and rats share this characteristic.

Answers

Answer:

I would write "terrestrial/lives on land during all life stages" between the frog and pigeon branches

Explanation:

Jaw evolution has started with fish, so i'd place that before the perch, evolution of four limbs is next and I would plate it between the perch and the frog. Evolution of an egg has ensured that organisms remain terrestrial during all stages of life and don't need to rely on water to lay their eggs. So I would place that between the frog and the pigeon. True mammary glands and true hair, as we know it formed on mammals so i'd place that between the pigeon and the rats (although synapsids evolved similar structures long before birds even existed). And lastly, I would place "walking on two legs" between rats and human branches. Because our ancestors evolved bipedalism relatively late.

If a solute has really strong bonds between its particles, would you expect it to form a solution that gets hold or cold? Explain your reasoning.

Answers

Answer:

The temperature of the solute/solvent without any external effect would decrease.

Explanation:

As the bonding between the solute particles is really strong, therefore a large amount of energy is required to overcome these forces. So that the new bonding between the solute and solvent is created.

In order to achieve this, there will be a lot of energy required and that is through the heating process. So the solution will require energy so the solute will dissolve fully either by provision of external force i.e stirring or by heating.

Which of the following aqueous solutions will have a pH that is significantly different from the rest?


0.1 M H 2SO 4


0.1 M HNO 3


0.1 M HC 2H 3O 2


0.1 M HCl

Answers

Among the given aqueous solutions, the solution with a significantly different pH from the rest is 0.1 M HC₂H₃O₂ (acetic acid).Option C

H₂SO₄ (sulfuric acid), HNO₃ (nitric acid), and HCl (hydrochloric acid) are strong acids that dissociate completely in water. They produce a high concentration of H₃O⁺ ions, resulting in a low pH. Acetic acid, on the other hand, is a weak acid that only partially dissociates in water. It produces a smaller concentration of H₃O⁺ ions, resulting in a higher pH compared to the strong acids.

When a strong acid like HCl, H₂SO₄, or HNO₃ is dissolved in water, it completely dissociates to release H₃O⁺ ions. The resulting solution will have a very low pH, usually close to 0. However, acetic acid (HC₂H₃O₂) only partially dissociates, and the concentration of H₃O⁺ ions is lower. As a weak acid, it has a higher pH compared to strong acids, typically around 2.4.

In summary, among the given options, the aqueous solution of 0.1 M HC₂H₃O₂ (acetic acid) will have a significantly different pH from the rest, with a higher pH value due to its weak acid nature.

Option C

Answers

2.62J of energy will be required to warm a silver metal from a temperature of 25°C to 27.5°C.

How to calculate joules?

The energy required in a calorimetry can be calculated using the following formula:

Q = m × c × ∆T

Where;

Q = quantity of heat absorbed or releasedm = mass of substancec = specific heat capacity∆T = change in temperature

According to this question, 4.37 g of silver should be heated from 25°C to 27.5°C. The heat required is as follows:

Q = 4.37 × 0.24 × (27.5 - 25)

Q = 1.0488 × 2.5

Q = 2.62J

The total pressure is 101.1 kPa. The partial pressure of He is 80.1 kPa. The partial pressure of N₂ is 16.2 kPa. Substitute and solve for O₂:


[tex]\displaystyle \begin{aligned} (101.2\text{ kPa}) & = P_\text{O$_2$} + (16.2\text{ kPa}) + (80.1\text{ kPa}) \\ \\ P_\text{O$_2$} & = 4.9\text{ kPa}\end{aligned}[/tex]
