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/molMass = 12g/mol × 3molMass = 36g. Therefore, there are 36 grams in 3.00 moles of carbon.Learn more at: https://brainly.com/question/15743584?referrer=searchResults

How many ATOMS are in 7.32 moles of sulfur
dioxide?
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.

THE MYSTERY SALT
Imagine that you have a barrel of salt, but you forgot to label it. You know it must be either KNO3, or KCl.
You look at the solubility curves for KNO3 and KCl and you find that at 35 degrees Celsius, 100 g of water can dissolve about 30 g of KNO3, or about 37 g of KCl.
The solubility curves disappear. You only remember the solubility for both salts at 35 degrees Celsius in 100g of water. You know absolutely nothing else about these salts.
You have a scale, a hot plate, a thermometer, empty beakers, and plenty of water. You do NOT have any labeled KNO3 or KCl.
1. What property can you use to determine whether the barrel contains KNO3 or KCl? Hint: Name the property you could use to identify the mystery salt? (1 point)
2. Explain exactly what you would do. Another person should be able to perform your test by following your procedure. Do not bother with why you are doing these steps.

What is the pH of a 2.0 × 10-4 M HCl solution?
Answer:
pH = 3.69
Explanation:
HCl is a strong acid. It will disscociates completely into dissoluted ions such that,
[tex][H^+]=2\times 10^{-4}\ M[/tex]
The formula for pH is given by :
[tex]pH=-log[H^+]\\\\pH=-log(2\times 10^{-4})\\\\pH=3.69[/tex]
So, the pH of the solution is 3.69.

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

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

What is the formula for the compound formed by Al3+ and N3- ?
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) = 0Therefore, we do not need any subscripts. List the metal's symbol (aluminum) then the nonmetal.
AlNTh formula for the compound, which is aluminum nitride, is AlN.

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.)
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
Which of these indicates that a liquid has transferred thermal energy to the air?
O The liquid increases in temperature, and its particles lose kinetic energy
O The liquid decreases in temperature, and its particles gain kinetic energy
O The liquid increases in temperature, and its particles gain kinetic energy.
O The liquid decreases in temperature, and its particles lose kinetic energy
No
Answer:
The liquid decreases in temperature and its particles lose kinetic energy.
Temperature is proportional to kinetic energy, so if temperature decreases, kinetic energy decreases. Energy has been removed from the liquid, because it is in the air

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
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
