How can you change the volume of gas being produced by the reaction?

Answer:

mass in a given volume

Explanation:

Density is the mass in a given volume or mass per unit volume of a substance.

Mass is defined by the amount of matter present in a substance.

Volume is the space occupied by a body.

Mathematically;

                      Density  = \(\frac{mass}{volume}\)  

From the mole ratio of the gases, 10 moles of hydrogen will produce 10 moles of water, and if 10.0 L of hydrogen and 6.0 L of oxygen were used, 10.0 L of water will be produced.

The mole ratio of the reactants in the formation of water can be shown from the equation below:

\(2H_2 + O_2 \rightarrow 2H_2O\)

Mole ratio of hydrogen to oxygen is 2:1

10 moles of hydrogen will require 5 moles of oxygen, therefore hydrogen is the limiting reactant.

10 moles of hydrogen will produce 10 moles of water.

1 mole of a gas has a volume of 22.4 L.

If 10.0 L of hydrogen and 6.0 L of oxygen were used, 10.0 L of water will be produced.

Therefore, the volume ratio of gas equals mole ratio of gas.

The amount of energy used to heat the copper is 333.855 J.

What is energy?

Energy is a fundamental concept that refers to the capacity of a system to do work or cause a change. Energy can exist in many different forms, including kinetic energy (energy of motion), potential energy (energy stored in an object due to its position or configuration), thermal energy (energy due to the motion of particles within a substance), chemical energy (energy stored in chemical bonds), electrical energy (energy associated with the movement of charged particles), and nuclear energy (energy stored in the nucleus of an atom).

To calculate the amount of energy used to heat the copper, we can use the formula:

Q = m * c * ΔT

where Q is the amount of energy used (in joules), m is the mass of the copper (in grams), c is the specific heat capacity of copper (in J/g°C), and ΔT is the change in temperature (in °C).

Given that the mass of copper is 26.2 g, the specific heat capacity of copper is 0.385 J/g°C, and the change in temperature is (58-23) = 35°C.

Plugging these values into the formula, we get:

Q = 26.2 g * 0.385 J/g°C * 35°C

= 333.855 J

Therefore, the amount of energy used to heat the copper is 333.855 J.

The correct option is e)t  a and b only. Riboflavin and deoxyribose are both components of the molecule, while phosphodiester bonds link the two together.

Molecule is a group of two or more atoms held together by covalent bonds. The atoms that make up a molecule can be from the same element, such as two hydrogen atoms, or from different elements, such as a hydrogen atom and an oxygen atom. Molecules can be as small as two atoms or as large as thousands of atoms. The properties of a molecule depend on how the atoms are arranged and the type of bonds that are formed.

Riboflavin is a B vitamin found in foods such as milk, eggs, and green vegetables, while deoxyribose is a five-carbon sugar that forms the backbone of DNA. Phosphodiester bonds are covalent chemical bonds which link the two components of the molecule together.

Answer:

according to the law,the pressure would increase if volume has been decreased.

Explanation:

the reason is that,pressure and volume are inversely proportional,if volume has been decreased that means the pressure would increase because decreased volume would create a sort of compacted situation for particles either of a liquid or gas,decreasing volume would bring these particle together, closer to each other because of decreased  and since the volume has decreased they dont have enough space,they would end up getting closer to each other most likely to collide, which drastically increase pressure .

Answer:

Answer is in photo

Explanation:

The order of strength of hydrogen bonds, dispersion forces, and dipole-dipole forces is as follows: Hydrogen bonding , Dipole-dipole interactions ,London dispersion forces.

Hydrogen bonding: Hydrogen bonding is the strongest type of intermolecular force. It occurs when a hydrogen atom is covalently bonded to a highly electronegative atom (such as nitrogen, oxygen, or fluorine) and is attracted to another highly electronegative atom in a nearby molecule. An example of a molecule that exhibits hydrogen bonding is water (H2O). Dipole-dipole interactions: Dipole-dipole interactions are slightly weaker than hydrogen bonding, but still stronger than London dispersion forces. They occur between molecules that have permanent dipoles, or regions of partial positive and negative charge. An example of a molecule that exhibits dipole-dipole interactions is acetone (CH3COCH3). London dispersion forces: London dispersion forces are the weakest type of intermolecular force. They are attractive forces that occur between all types of molecules and result from the temporary separation of charge that occurs as a result of the movement of electrons within a molecule. An example of a molecule that exhibits London dispersion forces is hexane (C6H14).

Answer:

Freezing point of solution = -2.740C

Explanation:

The solution is attached herewith

The normal freezing point of an aqueous solution of C₁₂H₂₂O₁₁ is -1.26°C

The freezing point depression can be calculated using the formula:

ΔTf = i* Kf*m ; where

The molality of the aqueous solution of C₁₂H₂₂O₁₁ is first determined using the formula:

The mass of water is unknown but is determined from the mass of the solute and solution from the formula:

mass of solute = number of moles * molar mass

moles of solute in 1 L solution = 0.7439 moles

molar mass of solute, C₁₂H₂₂O₁₁ = 342.0 g/mol

mass of solute = 0.7439 moles * 342.0 g

mass of solute = 254.41 g

mass of solution = density * volume

volume of solution = 1 L = 1000 mL

mass of solution = 1.35g/ml * 1000 mL

mass of solution = 1350 g

Therefore, mass of solvent (water) = 1350 g - 254.41 g

mass of solvent (water) = 1095.59 g

mass of solvent (water) in kg = 1095.59 g * 1 kg/ 1000 g

mass of solvent (water) in kg = 1.0956Kg

Thus, molality of solution = 0.7439 moles / 1.0956 Kg

molality of solution = 0.679 mol/kg

The freezing point depression, ΔTf, is then determined using the formula: ΔTf = i* Kf*m

Since C₁₂H₂₂O₁₁ is a non-electrolyte; i for C₁₂H₂₂O₁₁ = 1

Kf of water = 1.86 kg/mole

m = 0.679 mol/kg

ΔTf = 1 * 1.86 * 0.679

ΔTf = 1.26 °C

Therefore, freezing point depression, ΔTf = 1.26 °C

normal freezing point of solution = freezing point of water - freezing point depression

normal freezing point of solution = 0.0°C - 1.26°C

normal freezing point of solution = -1.26°C

Therefore, the normal freezing point of an aqueous solution of C₁₂H₂₂O₁₁ is -1.26°C
