If you react 59.54 g of S and 78 g of HNO3, how many grams of NO2 can you
theoretically produce?
S + 6 HNO3 + H2SO4 + 6 NO2 + 2 H2O
Answers
Answer:
56.94759 grams of NO2
Explanation:
Stoichiometric Equation:
1 S + 6 HNO3 → 1 H2SO4 + 6 NO2 + 2 H2O.
This is so you can create ratios between each compound in the reaction, and identify the limiting and excess reactants to determine exactly how much can be produced?
The coefficients or molecular quantity of each compound in the balanced equation represents the amount of moles.
To figure out how much can be produced, you have to convert 59.54 g of S into moles of S and 78 g of HNO3 into moles of HNO3.
A reference such as a periodic table can be very helpful as it has the atomic mass of each element which is the mass with respect to 1 mol of that element.

Answers
Answer:
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

Approximately how many formula units of NaCl are in 116.88g of table salt (NaCl), knowing that the molar mass of NaCl is 58.44g/mol?
Answers
Answer:
116.88g of table salt (NaCl) contains two formula units
Explanation:
Now,
We know that 1 formula unit of sodium chloride has a molar mass of 58.44g/mol
Hence;
Mass of 1 formula unit = 58.44g
Mass of x formula units = 116.88g
x = 116.88g * 1 formula unit/58.44g
x = 2 formula units
Therefore;
116.88g of table salt (NaCl) contains two formula units
Answer:
There are 1.2044 × 10²⁴ formula units of NaCl in 116.88 g of table salt (NaCl)
Explanation:
A formula unit is an empirical formula of the smallest collection or number of atoms in an ionic or covalent combination from which a compounds formula can be established and which are used to represent the compound stoichiometrically
Sodium chloride is an ionic compound and is represented by the formula unit NaCl as it composed of ions and is not therefoe represented by a molecular formula
The given mass of the table salt, NaCl = 116.88 g
The molar mass of NaCl = 58.44 g/mol = The mass of 1 mole of NaCl
1 mole of NaCl contains one Avogadro's number or 6.022 × 10²³ formula units of NaCl,
∴ 58.44 g of NaCl contains 6.022 × 10²³ formula units of NaCl
116.88 g of NaCl will have (116.88/58.44) × 6.022 × 10²³ = 1.2044 × 10²⁴ formula units of NaCl
The number of formula units of NaCl in 116.88 g of table salt (NaCl) = 1.2044 × 10²⁴ formula units of NaCl.

How much energy is released when 6.0 g of water is condensed from water to vapor?
Answers
Answer:6.0g x 1 mol/18.02g x 40,65 kJ/mol
Explanation: just did the quiz
13.6 kilojoules (kJ) of energy is released when 6.0 g of water is condensed from water to vapor.
To calculate the energy released when 6.0 grams of water is condensed from water to vapor, we need to use the concept of heat of vaporization (also known as enthalpy of vaporization). The heat of vaporization is the amount of energy required to change one gram of a liquid into vapor at its boiling point, without any change in temperature.
The heat of vaporization of water is approximately 40.7 kJ/mol at its boiling point (100°C or 373.15 K). We can use this information to calculate the energy released when 6.0 grams of water is condensed.
Step 1: Calculate the number of moles of water (H₂O) in 6.0 grams.
Molar mass of water (H₂O) = 2 g/mol (for hydrogen) + 16 g/mol (for oxygen) = 18 g/mol
Number of moles of water = Mass of water / Molar mass of water
Number of moles of water = 6.0 g / 18 g/mol = 0.333 moles
Step 2: Calculate the energy released during condensation.
Energy released = Number of moles of water × Heat of vaporization
Energy released = 0.333 moles × 40.7 kJ/mol = 13.6 kJ
Therefore, approximately 13.6 kilojoules (kJ) of energy are released when 6.0 grams of water is condensed from water to vapor.

What makes an atom stable?
a. Having the nucleus in the center
b. Being very small
c. Being neutral
d. Having the right number of protons and neutrons
Answers
Explanation:
An atom is stable if the forces among the particles that makeup the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. Instability of an atom's nucleus may result from an excess of either neutrons or protons.

24.2 mL.
Explanation:
Assuming constant temperature, we can solve this problem using Boyle's law, which states:
P₁V₁=P₂V₂Where:
P₁ = 0.98 barV₁ = 25 mLP₂ = 1.013 barV₂ = ?We input the data:
0.98 bar * 25 mL = 1.013 bar * V₂And solve for V₂:

The characteristics of two unknown intermolecular forces, X and Y, are compared in the table.

Y
Occurs between molecules with instantaneous dipoles Occurs between molecules with permanent dipoles and ions
Which of the following conclusions about the two intermolecular forces is correct?
X represents London dispersion forces, and Y represents ion-dipole forces.
X represents dipole-dipole forces, and Y represents ion-dipole forces.
X represents hydrogen bonding, and Y represents dipole-dipole forces.
X represents London dispersion forces, and Y represents dipole-dipole forces.
Answers
Answer:
X represents London dispersion forces, and Y represents ion-dipole forces.
Explanation:
London forces occurs between molecules that are normally non-polar (electrically symmetric). It arises from instantaneous dipoles in molecules. It occurs in all substances.
Permanent dipoles are caused by non-symmetric electron distribution in molecules leading to a permanent dipole in the molecule such as in HCl. Interaction between the permanent dipole in these molecules and an ion is called ion-dipole interaction.
Hence; X represents London dispersion forces, and Y represents ion-dipole forces.
X represents London dispersion forces, and Y represents ion-dipole forces.
London forces:
