the titration of 25.0 ml of an unknown concentration h2so4 solution requires 83.6 ml of 0.24 m lioh solution. what is the concentration of the h2so4 solution (in m)?

Answers

Answer 1

The titration of 25.0 ml of an unknown concentration h2so4 solution requires 83.6 ml of 0.24 m lioh solution. 0.20M is the concentration of the h2so4 solution (in m).

We'll begin by calculating the number of mole of LiOH in 83.6 mL of 0.12 M LiOH solution.

Volume = 83.6 mL = 83.6 / 1000 = 0.0836 L

Molarity of LiOH = 0.12 M, Mole of LiOH =?

Mole = Molarity × Volume

Mole of LiOH = 0.12 × 0.0836, Mole of LiOH = 0.010032 mole

Next, we shall determine the number of  mole of H₂SO₄ needed to react with 0.010032 mole of LiOH.

2LiOH + H₂SO₄ —> Li₂SO₄ + 2H₂O

From the balanced equation above, 2 moles of LiOH reacted with 1 mole of H₂SO₄. Therefore,

0.010032 mole of LiOH will react with =  = 0.005016 mole of H₂SO₄.

Finally, we shall determine the molaity of the H₂SO₄ solution.

Mole of H₂SO₄ = 0.005016 mole

Volume = 25 mL = 25 / 1000 = 0.025 L

Molarity of H₂SO₄ =?

Molarity = mole / Volume, Molarity of H₂SO₄ = 0.005016 / 0.025, Molarity of H₂SO₄ = 0.20 M

Percent concentration: This refers to how much solute dissolves in 100 g of solvent. If a solution's concentration is 20%, we know that there are 20 g of solute in every 100 g of solution. As an illustration, a solution is made by mixing 10 g of salt and 70 g of water. Concentration makes it less likely that you will overlook crucial facts. You can memorize information more quickly if you maintain your focus. Medical, cognitive, or psychological issues, sleep disorders, prescription side effects, alcoholism, or drug usage are all possible causes of concentration issues.

According to the electronegativity difference between the atoms in water, it would be appropriate to label hydrogen with the symbol 18+ and oxygen with the symbol 8+ st

Answers

The electronegativity of hydrogen is 2.0, while that of oxygen is 3.5.

Electronegativity is a chemical property that describes an atom's or functional group's tendency to attract electrons toward itself. An atom's electronegativity is affected by both its atomic number and the distance between its valence electrons and the charged nuclei.

It governs the distribution of shared electrons between two atoms in a bond. The greater an atom's electronegativity, the more strongly it attracts electrons in its bonds. The electronegativity of hydrogen is 2.0, while that of oxygen is 3.5. Because the difference in electronegativities is 1.5, water is a polar covalent molecule. This means that electrons are strongly attracted to the more electronegative element, but the atoms are not ionized.

The empirical equation is C4H11O2.

How do you locate empirical formulas?

Mass of C=1.900g CO2×12.01 g C/44.01g CO2=0.5185 g C

Mass of H=1.070g H2O×2.016 g H/18.02g H2O=0.1197 g H

Mass of C + Mass of H =0.5185 g + 0.1197 g =0.6382 g

This is less than the mass of the sample.

The missing mass must be caused by O.

In comparison to hot working, cold working uses less heating, yields a better surface polish, has greater dimensional qualities, and has fewer contamination issues.

Heat is the energy transfer that happens as a result of the temperature differential between a system and its surroundings. Heat is the energy transmission that uses or stimulates disordered molecular motion in the environment at the molecular level. Heating is the result of the movement of kinetic energy from one media or item to another, or from an energy source to a medium or object. Radiation, conduction, and convection are the three possible mechanisms for this type of energy transmission. When the temperature rises, atoms and molecules move more quickly and collide, creating thermal energy (also known as heat energy).

Mg atoms have two electrons in their outermost orbitals. An atom has the ability to lose two electrons and he becomes Mg²⁺.

Lewis structure, also called Lewis symbols, are used to represent electrons as dots. Two electrons are donated from the Mg atom to produce a magnesium ion or Mg²⁺.

The electronic configuration of Mg can be written as 1s2 2s2 2p6 3s2, whereas the electronic configuration of Mg²⁺ was found to be 1s2 2s2 2p6. Element number magnesium is 12.

Mass concentration, molarity, number concentration, as well as volume concentration are four different categories of mathematical description. Any type of chemical mixture can be referred to by the term "concentration," but solutes but also solvents in solutions are most frequently mentioned. There are different types of molar (amount) concentration, including normal concentration as well as osmotic concentration. Concentration is frequently described qualitatively in everyday, non-technical language by using adjectives like "dilute" for solutions with a low concentration as well as "concentrated" for solutions with a high concentration.


Here, we have given two solution with their conc. and volume.
So, formula used to calculate conc. is
M1V1 = M2V2

let,
M1 = molarity of fe2
V1 = volume of fe2 used
M2 = molarity of ce4
V2 = volume of ce4 used
now, M1 X 20 = 0.1403 x 23.91

I'm not sure about this protein) which then transfers the one electron to the cytochrome c1 subunit of complex three which transfers a single electron to the mobile cytochrome c in the P side (intermembrane space)

The other electron carried by the QH2 is transferred to Heme bL and then Heme bH in the cytochrome b subunit which then transfers the electron to a Q making it a (dotQ-) a semiquinone radical. The original QH2 has been fully oxidized to Q at this point and released

Second QH2 docks and goes through the same process generating a second molecule of cytochrome c and fully reducing the semiquinone to the QH2.This means, in the overall process 2QH2 were oxidized to produce two cytochrome c but two of the electrons were used to generate 1QH2 so there was only a net of one QH2 to make those two cytochrome c

4. Explain why diisopropylamine is a stronger base than aniline nh2 diisopropylamine aniline.

Answers

Answer: Cyclohexylamine is a stronger base than aniline because in aniline electron pair is involved in conjugation, which makes the electron pair unavailable, where as in cyclohexyl amine, the −NH

2

 group is out side the ring and there is no resonance in the ring also, thereby the lone pair present on the nitrogen is freely available, resulting in a stronger base.

1. Endothermic

2. Exothermic

3. Endothermic

4. Endothermic

5. Exothermic

A reaction that emits heat and has a net negative standard enthalpy change is said to be exothermic. Any combustion procedure, iron rusting, and water freezing are a few examples. Exothermic reactions are those in which heat-based energy is released into the surrounding environment. If heat is absorbed by the system from the environment, the reaction or physical change is endothermic. As a result of the system absorbing heat from its surroundings during an endothermic process, the environment cools.
