Answer:

Yield is the income on an investment over a period of time. It is calculated by taking interest or dividends earned by the investment, then dividing them by the value of the investment. It's usually expressed as an annual percentage, and excludes capital gain, which are the profits earned from buying something at one price and selling it at a higher price.

A 0. 1220 g vitamin c tablet was dissolved in acid. This required 11. 50 ml of 0. 01740 m kio3 to reach the endpoint. Calculate

kodGreya [7K]

86.66 % by weight of ascorbic acid in the tablet, when 0. 1220 g vitamin c tablet was dissolved in acid. This required 11. 50 ml of 0. 01740 m $KIO_3$ to reach the endpoint.

<h3>What is a balanced chemical equation?</h3>

A balanced chemical reaction is an equation that has equal numbers of each type of atom on both sides of the arrow.

$3C_6H_80_6 +3I_2 +KIO_3 +5KI +6H^+$ → $3C_6H_60_6 +6I^- +3I_2+6K^+ +3H_2O$

So, the balanced chemical equation for the reaction will be:

$3C_6H_8O_6 +KIO_3$ → $3C_6H_6O_6 +KI + 3H_2O$

That means, 3 mol of of ascorbic acid reacts with 1 mol of $KIO_3$

Moles of $KIO_3$ available is 0.0174 X 0.0115 =0.0002001 mol

Moles of ascorbic acid to be yielded should be 3 X 0.0002001 =0.0006003

So, percent mass of ascorbic acid in the tablet will be:

(0.1057 / 0.1220) X 100 %

=86.66 %

Hence, the third option is the correct answer.

Olegator [25]

Answer:

A-10

Explanation:

In the SI, designations of multiples and subdivision of any unit may be arrived at by combining with the name of the unit the prefixes deka, hecto, and kilo meaning, respectively, 10, 100, and 1000, and deci, centi, and milli, meaning, respectively, one-tenth, one-hundredth, and one-thousandth.

What is meant by the term neutral in relation to atoms?

Sonbull [250]

Answer:

it means positive and negative charges are equal.

Explanation:

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.

when a neutral atom loses a electron positive charge is created because number of protons are positive charge becomes greater than negative charge.

X → X⁺ + e⁻

When a neutral atom accept the electron negative charge is created because negative charge is become greater than positive charge.

X + e⁻ → X⁻
