Solid sodium reacts with liquid water to form hydrogen gas according to the equation
2 Na(s) + 2 H₂O(l) → 2 NaOH(aq) + H₂(g)
What is the pressure (in atm) of hydrogen gas in the 20.0 L headspace of a reactor vessel when 3.36 kg sodium is reacted with excess water at 50.0 °C?

Answers

The pressure (in atm) of hydrogen gas in the 20.0 L headspace of a reactor vessel when 3.36 kg sodium is reacted with excess water at 50.0 °C can be calculated using the ideal gas law, which states that the pressure, volume, and temperature of a gas are related by the equation PV = nRT, where P is the pressure of the gas, V is the volume of the gas, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature of the gas in Kelvin.

To calculate the pressure of the hydrogen gas, we first need to determine the number of moles of hydrogen gas produced by the reaction. We can do this by using the balanced chemical equation for the reaction, which is 2 Na(s) + 2 H₂O(l) → 2 NaOH(aq) + H₂(g).

From the balanced chemical equation, we can see that for every 2 moles of sodium that react, 1 mole of hydrogen gas is produced. Therefore, if 3.36 kg of sodium is reacted with excess water, the number of moles of hydrogen gas produced is 3.36 kg / (22.99 g/mol) = 146.4 moles.

Next, we need to convert the temperature of the gas from degrees Celsius to Kelvin. This can be done by adding 273.15 to the temperature in Celsius, which gives us a temperature of 50.0 + 273.15 = 323.15 K.

Now that we have the number of moles of hydrogen gas and the temperature of the gas, we can plug these values into the ideal gas law equation to calculate the pressure of the hydrogen gas:

P = (nRT) / V

P = (146.4 mol * 0.08206 L*atm / mol*K * 323.15 K) / 20.0 L

P = 4.31 atm

Therefore, the pressure (in atm) of hydrogen gas in the 20.0 L headspace of a reactor vessel when 3.36 kg sodium is reacted with excess water at 50.0 °C is 4.31 atm.

What is Specific heat?

The amount of energy required to increase a substance's temperature by one degree Celsius per gram is known as its specific heat. Although it can alternatively be expressed in terms of calories, specific heat is often expressed in Joules per gram per degree Celsius (J/g oC).

Fe₂O3 +

Answers

To calculate the % yield, you need to determine the actual yield of the reaction and compare it to the theoretical yield. The actual yield is the amount of product that is actually produced during the reaction, while the theoretical yield is the maximum amount of product that could be produced based on the amounts of reactants used.

In this case, the theoretical yield is 87,000 milligrams of iron, since this is the amount of product that was actually produced. The % yield is calculated by dividing the actual yield by the theoretical yield and multiplying by 100%.

Since the actual yield and the theoretical yield are the same in this case, the % yield is 100%. This means that the reaction had a perfect yield, with all of the reactants being converted into product.

What has the lowest volume 1kg lead, 1kg of iron, 1kg of gold, or 1kg of copper

Answers

Answer:

1 kg of lead occupies the smallest amount of space of the four substances

Explanation:

The densities of lead, iron, gold, and copper are 11.34 g/cm^3, 7.87 g/cm^3, 19.32 g/cm^3, and 8.96 g/cm^3, respectively. Therefore, the volumes of 1 kg of lead, iron, gold, and copper are:

Volume of 1 kg lead = 1000 g / 11.34 g/cm^3 = 87.94 cm^3

Volume of 1 kg iron = 1000 g / 7.87 g/cm^3 = 126.98 cm^3

Volume of 1 kg gold = 1000 g / 19.32 g/cm^3 = 51.93 cm^3

Volume of 1 kg copper = 1000 g / 8.96 g/cm^3 = 111.84 cm^3

As we can see, a kilogram of lead has the lowest volume of the four substances, with a volume of 87.94 cm^3. This is because lead is the densest of the four substances, which means that it has the highest mass per unit of volume. Therefore, 1 kg of lead occupies the smallest amount of space of the four substances

Ion-ion forces are the strongest because they involve the electrostatic attraction between two ions that have opposite charges. Ion-dipole forces involve the attraction between a charged ion and a polar molecule, which is weaker than the ion-ion forces. Hydrogen bonding is a particularly strong form of dipole-dipole interaction that is stronger than regular dipole-dipole forces.

Answers

When looking at the broken pieces of charcoal with a hand lens, you will see small pieces of black matter with a rough texture.

What is charcoal?

Charcoal is a combustible, black solid fuel made from partially burned wood, bone, or other organic matter. It is primarily used as a fuel for barbecues, grills, and other cooking methods, and is also used in art and blacksmithing. Charcoal is created by burning wood or other organic material in a limited amount of oxygen, reducing it to a carbon-rich substance. The material is then heated to high temperatures to burn off volatile compounds, leaving behind a black, porous material that is rich in carbon. Charcoal is more efficient than wood as a fuel source because it has a higher energy content and produces fewer pollutants.

The pieces of charcoal are made up of small grains of carbon that were formed when the wood was burned. The texture of the charcoal varies from coarse to fine, depending on the type of wood used in the burning process.

When compared to a piece of coal, the charcoal pieces are much smaller and the texture is more rough. Coal forms when plant materials are buried beneath layers of sediment, which prevents oxygen from reaching them. Over a period of millions of years, these plant materials slowly convert to a charcoal-like material called coal. The coal has a much smoother texture than the charcoal and is made up of larger, more compact pieces of carbon.

3.71 g of iron would be: 3.71/56 = 0.066 mol

The equivalent mole of copper that is produced would be; 3/2 x 0.066 = 0.099 mol.

Since, mass = mole x molar mass, the mass of 0.099 mol of copper would be: 0.099 x 64 = 6.34 grams

In other words, the theoretical yield of solid copper [Cu(s)] in grams is 6.34 grams.

which other element is likely to show a similar chemical reaction with oxygen as shown by magnesium, and to which group does it belong?

Answers

The chemical reaction between calcium (Ca) and strontium (Sr) is anticipated to be comparable to that of magnesium (Mg).

What substance resembles oxygen the most chemically?

Due to the fact that sulfur is located immediately beneath oxygen on the periodic table, they are chemically identical. The electron structures of these atoms are comparable. Because of this, sulfur can create a variety of compounds that are similar to those made of oxygen.

What happens when Group 2 elements and oxygen interact?

I Group 2 Elements and Oxygen Reactions. In the presence of air, the metal oxide tarnishes to create a layer on all Group 2 elements. They violently react with pure oxygen, forming a white ionic oxide. These metals (M) burn vigorously to create a white ionic oxide, M2+O2-, when heated in oxygen.

What particle is emitted (known as an alpha particle)

Answers

Answer:

Alpha particles are contains of two neutrons and two protons.

Answer:

Alpha particles are subatomic fragments consisting of two neutrons and two protons. Alpha radiation occurs when the nucleus of an atom becomes unstable (the ratio of neutrons to protons is too low) and alpha particles are emitted to restore balance.

calculate the mass defect in fe-56 if the mass of an fe-56 nucleus is 55.921 amu. the mass of a proton is 1.00728 amu and the mass of a neutron is 1.008665 amu.

Answers

The mass is 0.81167 amu

What is mass?

Mass is quantitative measure of interia a fundamental quantity of all matter.

Number of protons=42

Number of neutrons = 54

Mass of all the 42 protons = 42× 1.00728= 42.30576 amu

Mass of all 54 neutrons= 54 × 1.008665 = 54.46791 amu

Calculated mass of protons and neutrons in Mo-96 nucleus= 42.30576 amu + 54.46791 amu= 96.77367 amu

Actual mass of Mo-96 nucleus= 95.962 amu

Thus, the mass defect of Mo-96 nucleus= 96.77367 amu - 95.962 amu = 0.81167 amu
