Answer:

8 mol of hydrogen will react with 1 mol of sulfur.

Explanation:

We'll begin by writing the balanced equation for the reaction.

This is given below:

8H2 + S8 —> 8H2S

Now, let us carefully observe the mole ratio of the reactants.

This is illustrated:

The mole ratio of the reactants ( i.e H2 and S8) is 8 : 1

From the balanced equation above,

We can thus, concluded that:

8 moles of H2 will reacted with 1 mole of S8.

You are asked to weigh approximately 0. 4g of acetylsalicylic acid to the nearest mg. When you enter the data in grams in your l
Natali5045456 [20]

The significant figures will be 1.

As, weight of acetylsalicylic acid = 0. 4 g

We obtain 400 mg when we convert 0.4g of acetylsalicylic acid to mg.

So, 400 milligrams are worth 0.4 grams when converted to grams.

There is just one significant figure because 0 before a decimal is not significant i.e. 4.

<h3><u>What are significant figures?</u></h3>

The digits of a number that have relevance in relation to the measurement's resolution are known as significant figures. Additionally known as significant figures in chemistry. All experimental measurements are subject to some degree of uncertainity.

A certain electromagnetic wave has a wavelength of 6.25 x 10-7m. What is the
olasank [31]

Answer: 4.80 * 10¹⁴s⁻¹

Explanation:

Speed = Frequency * Wavelength

So:

Frequency = Speed/ Wavelength

Speed of light = 3 * 10⁸ m/s

Frequency = (3 * 10⁸ m/s) / (6.25 x 10⁻⁷m)

= 4.80* 10¹⁴hz

= 4.80 * 10¹⁴s⁻¹

In reality, a hydrate of iron(III) nitrate had to be used, not the anhydrous salt. As you may guess, some of the hydrate’s mass
liq [111]

<u>Answer:</u> The mass of nonahydrate iron (III) nitrate is 16.2 g

<u>Explanation:</u>

To calculate the number of moles for given molarity, we use the equation:

\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}

Molarity of Fe(NO_3)_3 = 0.0020 M

Volume of solution = 2 L

Putting values in above equation, we get:

0.0200M=\frac{\text{Moles of }Fe(NO_3)_3}{2L}\\\\\text{Moles of }Fe(NO_3)_3=(0.0200mol/L\times 2L)=0.04mol

The chemical equation for the decomposition of hydrated iron (III) nitrate follows:

Fe(NO_3)_3.9H_2O\rightarrow Fe(NO_3)_3+9H_2O

By Stoichiometry of the reaction:

1 mole of iron (III) nitrate is produced from 1 mole of hydrated iron (III) nitrate

So, 0.04 moles of iron (III) nitrate will be produced from = \frac{1}{1}\times 0.04=0.04mol of hydrated iron (III) nitrate

To calculate the mass from given number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Molar mass of nonahydrate iron (III) nitrate = 404.0 g/mol

Moles of nonahydrate iron (III) nitrate = 0.04 moles

Putting values in above equation, we get:

0.04mol=\frac{\text{Mass of nonahydrate iron (III) nitrate}}{404.0g/mol}\\\\\text{Mass of nonahydrate iron (III) nitrate}=(0.04mol\times 404.0g/mol)=16.2g

Hence, the mass of nonahydrate iron (III) nitrate is 16.2 g
