In a redox reaction, what happens to a substance’s charge when it is oxidized?

1 answer:

7 0

I use the acronym LEO for oxidation reactions. This stand for: Lose electrons Oxidation, so when oxidation occurs, electrons are lost. Due to electrons having a negative charge, substance undergoing oxidation have a more POSITIVE charge.

Pls Thank + Branliest its good for my ego :P

Given a balanced chemical equation between H2SO4(aq) and KOH(aq) H2SO4(aq) + 2 KOH(aq) → K2SO4(aq) + 2 H2O(l) What volume (in mL

Lynna [10]

Answer:

48.84mL

Explanation:

H2SO4 + 2KOH → K2SO4 + 2H2O

From the question:

nA = 1

nB = 2

From the question given we obtained the following information:

Ma = 0.43M

Va =?

Mb = 0.35M

Vb = 120mL

Using MaVa / MbVb = nA/nB, we can easily find the volume of the acid required. This is illustrated below:

MaVa / MbVb = nA/nB

0.43 x Va / 0.35 x 120 = 1/2

Cross multiply to express in linear form

2 x 0.43 x Va = 0.35 x 120

Divide both side by the (2 x 0.43)

Va = (0.35 x 120) /(2 x 0.43)

Va = 48.84mL

Therefore, the volume of H2SO4 required is 48.84mL

At what volume of added acid is the phph calculated by working an equilibrium problem based on the initial concentration and kbk

nikdorinn [45]

In an acid-base neutralization reaction, the equilibrium reaction would be between a weak base and its conjugate strong base. So, this must be the basis of the volume of added base.

pH is used to measure whether the substance is acidic, basic or neutral and the range is 0 - 14.

<h3>What is Neutralization Reaction ? </h3>

Neutralization reaction is a chemical reaction in which an acid and a base react quantitatively with together.

Neutralization reaction equation:

Acid + Base → Salt + Water

Thus from the above conclusion we can say that In an acid-base neutralization reaction, the equilibrium reaction would be between a weak base and its conjugate strong base. So, this must be the basis of the volume of added base.

Part 1. Determine the molar mass of a 0.622-gram sample of gas having a volume of 2.4 L at 287 K and 0.850 atm. Show your work.

zaharov [31]

If a sample of gas is a 0.622-gram, volume of 2.4 L at 287 K and 0.850 atm. Then the molar mass of the gas is 7.18 g/mol

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates to the macroscopic properties of ideal gases.

An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

Given :

V = 2.4 L = 0.0024

P = 86126.25 Pa

T = 287 K

m = 0.622

R = 8.314

The ideal gas equation is given below.

n = PV/RT

n = 86126.25 x 0.0024 / 8.314 x 287

n = 0.622 / molar mass (n = Avogardos number)

Molar mass = 7.18 g

Hence, the molar mass of a 0.622-gram sample of gas having a volume of 2.4 L at 287 K and 0.850 atm is 7.18 g
