How many moles of magnesium atoms react with 1 mole of oxygen molecules?

Answers

Answer 1

1 mole of magnesium atoms will react with 2 moles of oxygen molecules. This is because the chemical equation for the reaction between magnesium and oxygen is: Mg + O2 → MgO.

What is chemical equation?

A chemical equation is a symbolic representation of a chemical reaction, showing the reactants (starting materials) on the left side and the products (resulting substances) on the right side. The symbols used to represent the reactants and products are chemical formulas, which use the symbols of the elements in the reaction. The arrow between the reactants and products indicates the type of reaction taking place. The coefficients next to the symbols and formulae of entities indicate the number of moles of each species that are involved in the reaction. The overall reaction is balanced when the number of atoms of each element on the left side of the equation is equal to the number of atoms of that element on the right side of the equation.

This equation shows that for every 1 mole of magnesium atoms, 2 moles of oxygen molecules are required for the reaction to take place. Therefore, 1 mole of magnesium atoms will react with 2 moles of oxygen molecules.

the enthaply of formation of water is -285.8kj/mol. what can be inferred from this statement

Answers

Answer:   It takes 285.8 kJ of energy to form one mole of water

Explanation:

The enthalpy of formation of a substance is the change in enthalpy that occurs when a substance is formed from its elements in their standard states. The enthalpy of the formation of water is -285.8 kJ/mol, which means that it takes 285.8 kJ of energy to form one mole of water from its elements (hydrogen and oxygen) under standard conditions. This value is negative, which means that the formation of water releases energy. This is why water is often referred to as an "exothermic" substance because it releases energy when it is formed. The negative value of the enthalpy of formation for water can be explained by the fact that the bonds formed between hydrogen and oxygen atoms in water are stronger than the bonds between hydrogen and oxygen atoms in the individual elements. This means that it takes less energy to break the bonds in the elements than it releases when the bonds in water are formed, resulting in a net release of energy.

Based on the formula to determine the freezing point depression of the solvent, the freezing point of the solution is 263.85 K.

What is the freezing point of a substance?

The freezing point of a substance is the temperature at which the liquid changes to solid without any further decrease in temperature occurring during the process.

The addition of solute substances in liquids usually lowers the freezing point of the liquid solvent.

The formula to determine the freezing point depression of solvent is given below:

ΔT = i * Kf * m

where'

ΔT is the change in freezing point,i is the van't Hoff factor,Kf is the freezing point depression constant, andm is the molality of the solution.

The molality of the given solution = moles of solute/kg of solvent

moles of solute = 46/92

mass of solvent = 100 g or 0.1 kg

Molality of solution = (46/92) / 0.1

Molality of solution = 5

for glycerine, i = 1

ΔT = ΔT = 1 * 1.86 * 5

ΔT = 9.3

Answers

Answer:

Osmosis is taking place in the vessel, where a 10% solution of sodium chloride is on one side of the semipermeable membrane and a 2% solution of sodium chloride is on the other side. Osmosis is a special case of diffusion, where water moves from an area of higher concentration to one of lower concentration. In this case, water will move from the 10% solution to the 2% solution, as it has a higher solute concentration. This process is known as osmoregulation and it involves maintaining salt and water balance across membranes within the body’s fluids. The key to remember about osmosis is that water flows from the solution with the lower solute concentration into the solution with higher solute concentration. As such, in this case, water will flow from the 2% solution to the 10% solution.

Answers

The mass of [tex]IF_5[/tex] that would be in a 15.88 L sample at 378 K and 0.935 will be 106.51 grams.

Ideal gas problem

The problem can be solved by first using the ideal gas equation to know the number of moles of the gas that is present.

PV = nRT

P = 0.935, V = 15.88 L, T = 378 K, R = 0.082

Making n the subject of the formula:

n = PV/RT

  = (0.935x15.88)/(0.082x378)

   = 0.48 moles of the gas

Recall that, mass = mole x molar mass

The molar mass of [tex]IF_5[/tex] is 221.89 g/mol

Mass of 0.48 moles [tex]IF_5[/tex] = 0.48 x 221.89

if 3.38g of CuNO3 IS DISSOLVED IN WATER TO MAKE 0.220 M solution what is the volume of the solution in milliliters"

Answers

Answer:

To determine the volume of the solution in milliliters, we need to know the mass of CuNO3 and the concentration of the solution.

Given that 3.38g of CuNO3 is dissolved in water to make a 0.220 M solution, we can use the following formula to calculate the volume of the solution:

Volume = (Mass of CuNO3) / (Concentration of solution)

Plugging in the given values, we have:

Volume = (3.38 g) / (0.220 M)

Converting the mass to grams and the concentration to moles/liter, we have:

Volume = (3.38 g) / (0.220 mol/L)

Calculating, we find that the volume of the solution is approximately 15.36 liters.

To convert the volume to milliliters, we can multiply the volume in liters by 1000. In this case, the volume in milliliters is 15,360 ml.

Therefore, the volume of the solution in milliliters is approximately 15,360 ml.

The Clausius–Clapeyron equation can be used to find the heat of vaporization:

  [tex]\ln{P}=-\dfrac{\Delta H_{\text{vap}}}{R}\left(\dfrac{1}{T}\right)+C[/tex]

Solving for ∆H, we find ...

  [tex]\Delta H_{\text{vap}}=-\dfrac{R\cdot\ln{\dfrac{P_1}{P_2}}}{\dfrac{1}{T_1}-\dfrac{1}{T_2}}\\\\\\\Delta H_{\text{vap}}=-\dfrac{8.314\cdot\ln{\dfrac{760}{135}}}{\dfrac{1}{429}-\dfrac{1}{373}}\approx 41052.8[/tex]

The heat of vaporization of pinene is about 41 kJ/mol.

Vapor pressure

Rearranging the above equation to give P1, we have ...

  [tex]\ln{\dfrac{P_1}{P_2}}=-\dfrac{\Delta H_\text{vap}}{R}\left(\dfrac{1}{T_1}-\dfrac{1}{T_2}\right) \\\\\\P_1=P_2\cdot e^{-\frac{\Delta H_\text{vap}}{R}\left(T_1^{-1}-T_2^{-1})}[/tex]

Carbon was discovered by the ancient Egyptians, and it gets its name from the Latin word "carbo," which means "charcoal."

Carbon is a nonmetal that is located in Group 14 of the periodic table. It has a unique ability to form a wide variety of chemical compounds, which is one of the reasons it is so important in modern chemistry. Carbon has four valence electrons, which allows it to form stable chemical bonds with other elements.

Carbon is a chemical element that is found in all living things. It is a key component of proteins, DNA, and other essential biomolecules. Carbon can exist in several different forms, including graphite, diamond, and various forms of carbon-based compounds called organic molecules.

Carbon has many important implications for society. It is used as a fuel to produce energy, and it is also a key ingredient in the production of steel and other metals. Carbon is also an essential component of many plastics and other synthetic materials. However, carbon can also have negative impacts on the environment, as the burning of fossil fuels releases carbon dioxide into the atmosphere, contributing to climate change.

Carbon has many practical applications, including its use as a fuel, a structural material, and a chemical feedstock. However, carbon can also be hazardous in certain situations. For example, inhaling carbon monoxide can be deadly, and carbon dust can be explosive. Carbon is commonly encountered in many different forms, including coal, oil, and natural gas.

Personally, I think that carbon is a very interesting element with a wide range of important applications. It is fascinating to consider the role that carbon plays in the biology of living organisms, as well as its practical uses in industry and technology.

Stoichiometric problems

From the balanced equation of the reaction, the mole ratio of the reactants is 1:3.

Mole of 50.0 g [tex]Fe_2O_3[/tex] = 50/160 = 0.3125 mol

Mole of 10.0 g CO = 10/28 = 0.3571 mol

Stoichiometric equivalent of  [tex]Fe_2O_3[/tex] = 0.3571/3 = 0.1190 mol

In other words,  [tex]Fe_2O_3[/tex] is in excess.

Excess mole = 0.3125 - 0.1190 = 0.1935 mol

Mass of 0.1935 mol [tex]Fe_2O_3[/tex] = 0.1935 x 160 = 30.96 grams

Mole ratio of CO to Fe = 3:2

Equivalent mole of Fe that would be formed = 0.3571 x 2/3

                                                                          = 0.2381 mol

Mass of 0.238 mol Fe = 0.238 x 56 = 13.328 grams

Percent yield of Fe = 11.5/13.328 x 100 = 86.28%

Mole of 75 gk CO2 = 75000/44 = 1704.55 mol

Mole ratio of CO2 and Co = 1:1

Equivalent mole of CO = 1704.55 mol

Mass of 1704.55 mol CO = 1704.55 x 28 = 47.73 kg

80.7% = 47.73 kg

100% = 100 x 47.73/80.7

Average drop volume is a measurement of a droplet's average volume. It is employed in a wide range of applications, including laboratory experimentation, medical research, and medication delivery systems.

It aids in deciding the proper amount of liquid to utilize in a certain condition. It also aids in the creation of novel pharmaceuticals and assuring exact and constant dosing in medical treatments.

You may calculate the average drop volume by dividing the total amount of water (30.0 mL) by the number of drops (15). That is to say:

(30.0 mL divided by 15 drops = 2.0 mL/drop)

Hence where the number of drops is 15mL and the volume of one drop is 1.00mL, the average Volume of a Drop is 2.0mL
