Starting with 9.3 moles of O2, how many moles of H2S will be needed and how many moles of SO2 will be produced in the following

tensa zangetsu [6.8K]

Answer: The amount of hydrogen sulfide needed is 6.2 moles and amount of sulfur dioxide gas produced is 6.2 moles

Explanation:

We are given:

Moles of oxygen gas = 9.3 moles

The chemical equation for the reaction of oxygen gas and hydrogen sulfide follows:

$2H_2S+3O_2\rightarrow 2SO_2+2H_2O$

For hydrogen sulfide:

By Stoichiometry of the reaction:

3 moles of oxygen gas reacts with 2 moles of hydrogen sulfide

So, 9.3 moles of oxygen gas will react with = $\frac{2}{3}\times 9.3=6.2mol$ of hydrogen sulfide

For sulfur dioxide:

By Stoichiometry of the reaction:

3 moles of oxygen gas produces 2 moles of sulfur dioxide

So, 9.3 moles of oxygen gas will produce = $\frac{2}{3}\times 9.3=6.2mol$ of sulfur dioxide

Hence, the amount of hydrogen sulfide needed is 6.2 moles and amount of sulfur dioxide gas produced is 6.2 moles

An iron nail rusts when exposed to oxygen. According to the following reaction, how many grams of iron(III) oxide will be formed

natka813 [3]

Answer: 103.8 g of $Fe_2O_3$ , 0.65 moles of

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}$

$\text{Moles of} O_2=\frac{31.1}{32}=0.975moles$

Thus $O_2$ is the limiting reagent as it limits the formation of product and $Fe$ is the excess reagent.

$4Fe(s)+3O_2(g)\rightarrow 2Fe_2O_3$

According to stoichiometry :

3 moles of $O_2$ produce = 2 moles of $Fe_2O_3$

Thus 0.975 moles of $O_2$ will produce= $\frac{2}{3}\times 0.975=0.65moles$ of $Fe_2O_3$

Mass of $Fe_2O_3=moles\times {\text {Molar mass}}=0.65moles\times 159.69g/mol=103.8g$

Thus 103.8 g of $Fe_2O_3$ will be produced.

Steven had a sample of ethanol and wanted to see if it would boil at the temperature found in his textbook. His experiment yield

Natasha_Volkova [10]

Answer:

17.04%

Explanation:

Actual Value = 173.1

Measured Value = 143.6

Percent error is obtained using the equation;

Percent error = (Measured - Actual) / Actual ]* 100

Percent error = [ (143.6 - 173.1) / 173.1 ] * 100

The absolute value of (Measured - Actual) is taken,

Percent Error = [29.5 / 173.1 ] * 100

Percent Error = 0.1704 * 100 = 17.04%

Aqueous solutions of silver nitrate (AgNO3) and iron(III) chloride (FeCl3) are mixed together. Which ion combines with the chlor

garik1379 [7]

Hello there!

The correct answer is Ag⁺.

If we look at the solubility rules, it says that most chlorides are soluble, except with Ag⁺, and Pb²⁺.

I hope this helps!
