How many ATOMS are in 7.32 moles of sulfur
dioxide?

Answers

Using the concept of Avogadro's number, the number of atoms present is 4.4 * 10^24 atoms.

What is Avogadro's number?

Professor Avogadro provided a nice way of calculating the number of atoms in a molecules by the use of the Avogardro's number. Now we know that 1 mole of a substance contains about 6.02 * 10^23 atoms, molecules ions etc.

Hence;

1 mole of sulfur dioxide contains 6.02 * 10^23 atoms

7.32 moles of sulfur dioxide contains 7.32 moles  * 6.02 * 10^23 atoms/1 mole

= 4.4 * 10^24 atoms.

What is the formula for the compound formed by Al3+ and N3- ?



Answers

Answer:

[tex]\boxed {\boxed {\sf AlN}}[/tex]

Explanation:

The goal when forming compounds is to achieve a net charge of 0.

We are given aluminum with a charge of 3+  and nitrogen with a charge of 3-.

These charges are equal and opposite, so one of each will equal 0.

3+ (Al) + 3- (N) = 0

Therefore, we do not need any subscripts. List the metal's symbol (aluminum) then the nonmetal.

AlN

Th formula for the compound, which is aluminum nitride, is AlN.

How many grams are in 3.00 moles of carbon

Answers

Answer: Ok I think The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Carbon, or 12.0107 grams. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between moles Carbon and gram. 12 grams

This means that the atomic mass or atomic weight (12 grams) of carbon is equal to exactly 1 mole of carbon.

hope this helps have a awesome night/day❤️✨

Explanation:

There are 36 grams in 3.00 moles of carbon.

HOW TO CALCULATE MASS:

The mass of a substance can be calculated by multiplying the number of moles by its molar mass. That is;

mass (g) = no. of moles (mol) × molar mass (g/mol)

According to this question, 3 moles of carbon was given. The mass can be calculated as follows:

atomic mass of Carbon = 12g/mol

Mass = 12g/mol × 3mol

Mass = 36g.

Therefore, there are 36 grams in 3.00 moles of carbon.

If ONE mole of rocket fuel, ammonium perchlorate, NH4ClO4, is allowed to react with excess Al so that all of the NH4ClO4 is consumed, how many molecules of water will be produced? (All reactants & products are present in a 1:1 ratio.)

Answers

Answer:

9.03×10²³ molecules of H₂O

Explanation:

To solve this, we need to propose the reaction

NH₄ClO₄  →  ammonium perchlorate

Al → Aluminum

Those are the reactants; the reaction is:

6NH₄ClO₄  +  10Al →  5Al₂O₃ + 3N₂ + 6HCl + 9H₂O

Then, water is one of the products. If we see the reaction, is a redox type.

Ratio is 6:9. In conclussion:

6 moles of ammonium perchlorate can produce 9 moles of H₂O

Then 1 mol of salt, may produce (1 . 9)/6 = 1.5 moles of water

Let's count the molecules:

1.5 mol . 6.02×10²³ molecules /mol = 9.03×10²³ molecules of H₂O

how many grams of iorn reacts with 71 grams of chlorine to produce 117 grams of sodium chloride

Answers

Answer:

The answer to your question is: 71 g of Chlorine

Explanation:

Na = 46 g

Cl = ?

NaCl = 117 g

Equation

                     2 Na     +     Cl₂   ⇒   2 NaCl          

                     46g              X              117g

If we consider the law of conservation of matter, we know that the mass of the reactants equals the mass of the products, then

                   mass Na + mass Cl₂  = mass NaCl

                    46 g + X = 117

                    X = 117 - 46

                   x = 71 g of Chlorine

A reaction is expected to produce 28.3 moles of hydrogen gas. If the hydrogen is collected at 297 K and 1.08 atm, what is the volume? 305 L H2 639 L H2 948 L H2 1,240 L H2

Answers

Answer:

The correct answer is 639 L H₂

Explanation:

We use the ideal gas equation:

We have the following data:

n = 28.3 mol

T= 297 K

P= 1.08 atm

R= 0.082 L.atm/K.mol (gas constant)

We introduce the data in the gas equation to calculate the volume (V):

PV=nRT

⇒V =nRT/P = (28.3 mol x 0.082 L.atm/K.mol x 297 K)/(1.08 atm) = 638.2 L ≅ 639 L

Therefore, the correct option is  639 L H₂

639 L H2

How many moles of magnesium bromide are formed when 3.0 moles of magnesium reacts with 2.0 moles of bromine

Answers

Answer:

Reaction:

[tex]2Mg + Br_{2} >> 2MgBr[/tex]

Explanation:

Hello there, I think this is a limiting agent question.

When 3 moles of Mg is reacted with 2 moles of Br2, because of ratio, we just need 1.5 moles of Br2, so Mg is a limiting agent.

So 3 moles of Mg will make 3 moles of MgBr

Taking into account the stoichiometry of the reaction, 2 moles of magnesium bromide are formed when 3.0 moles of magnesium reacts with 2.0 moles of bromine.

The balanced reaction is:

Mg + Br₂ ⇒ MgBr₂

Then, by stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Mg: 1 mole Br₂: 1 moleMgBr₂: 1 mole

On the other side, the limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

To determine the limiting reagent, it is possible to a simple rule of three as follows: if by stoichiometry 1 mole of bromine reacts with 1 moles of magnesium, how much moles of bromine will be needed if 3moles of magnesium react?

[tex]moles of bromine=\frac{1 moles of bromineX3 mole of magnesium}{1 mole of magnesium}[/tex]

moles of bromine=3 moles

But 3 moles of bromine are not available, 2 moles are available. Since you have less moles than you need to react with 3 moles of magnesium, bromine will be the limiting reagent.

Finally, the following rule of three can be applied: if by reaction stoichiometry, 1 mole of bromine forms 1 mole of magnesium bromide, 2 moles of bromine forms how many moles of magnesium bromide?

[tex]moles of magnesium bromide=\frac{2 moles of bromine*1 moles of magnesium bromide}{1 mole of bromine}[/tex]

moles of magnesium bromide= 2 moles

In summary, 2 moles of magnesium bromide are formed when 3.0 moles of magnesium reacts with 2.0 moles of bromine.
