Which Of The Following Is A Correctly Written Thermochemical Equation?2C8H18 +25O2 16CO2 + 18H2O, H =

Answers

Answer 1

Answer:

The second option

Explanation:

Answer 2
The correct answer is:

C5H12 (g) + 8O2 (g) → 5CO2 (g) + 6H2O (l), ΔH = –3,536.1 kJ/mol

Explanation:

The correctly written thermochemical equation should include the balanced chemical equation and the corresponding enthalpy change (ΔH). The balanced chemical equation must have equal numbers of atoms on both sides of the equation, and the state of each substance should be indicated. The enthalpy change should be written with the correct sign (positive or negative) and unit (kJ/mol).

The first equation is correctly balanced, but the enthalpy change is not correct. The correct enthalpy change for this reaction is –5,471 kJ/mol, but it is written as a positive value in the equation. The correct enthalpy change should be written as ΔH = –5,471 kJ/mol.

The second equation is correctly balanced and includes the correct enthalpy change (ΔH = –3,536.1 kJ/mol). Therefore, it is the correctly written thermochemical equation

Hello! Can someone tell me how fans function and work? And what fans do? Ill include an imagine below!

Answers

Answer:

How fans work....Instead of sucking in hot air and pushing it down, the fan sucks up cool air and pushes it higher. When the fan forces cool air higher, the cool air forces warm air down. Instead of giving you more access to cool air in your room, the fan gives you more access to the warm air, making you feel nice and cozy.

What fans do....A fan, or a breeze, helps by replacing this hot, humid air with cooler, drier air that allows for more evaporation. Similarly, even without sweat, our body loses heat to the surrounding air simply by convection. ... The breeze from the fan carries that hot air away and perpetuates the process, effectively cooling you off.

At STP 32 g of O₂ would occupy by the same volume as  4 g of He

Further explanation

Complete question

At STP 32 g of O₂ would occupy by the same volume as:

4.0 g of He8.0 g of CH₄64 g of H₂32 g of SO₂

Standard Conditions

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.

So the gas will have the same volume if the number of moles is the same

mol of 32 grams of O₂ :

\(\tt \dfrac{32}{32}=1\)

He

\(\tt mol=\dfrac{4}{4}=1\)

CH₄

\(\tt mol=\dfrac{8}{16}=0.5\)

H₂

\(\tt mol=\dfrac{64}{2}=32\)

SO₂

\(\tt mol=\dfrac{32}{64}=0.5\)

So mol of 4 g He = mol of 32 g O₂

STP is the standard temperature and pressure of the gas to compare with the experimental data. At STP 32 gm of oxygen is equivalent to 4 gm of helium.

What is STP?

STP is the standard temperature and pressure of 0 degrees Celsius and 1 atm. At this temperature and pressure, the volume of the gas is 22.4 L/mol.

So, if the moles of the 32 gm oxygen are the same as the other element then the volume will also be the same. Here, the moles of oxygen are 1 mol.

Moles of 4 gm helium is 1, 8 gm methane is 0.5 mol, 64 gm dihydrogen is 32 mol, and 32 gm sulfur dioxide is 0.5 mol.

Therefore, the mole of 4 gm helium is equivalent to the mole of 32 gm oxygen.

Answers

The equation C2H4(g) + H2(g) + C2H6(g) → Caco3(s) + Cao(s) + CO2(g) shows an increase in entropy due to the formation of a gas as a product. Option A

In this equation, the reactants on the left-hand side consist of gases (C2H4 and H2), while the products on the right-hand side include a solid (Caco3) and a gas (CO2).

When a reaction involves a change from gaseous to solid or liquid states, there is typically a decrease in entropy because the particles become more ordered and constrained in the solid or liquid phase.

Conversely, when a reaction involves the formation of gases, there is generally an increase in entropy because gases have higher degrees of molecular motion and greater freedom of movement compared to solids or liquids.

In the given equation, the reactants include three gaseous compounds (C2H4, H2, and C2H6), and one of the products is a gas (CO2). Therefore, the overall entropy of the system increases during this reaction.

The equation Fe(s) + S(s) → FeS(s) does not show an increase in entropy. Both the reactants (Fe and S) and the product (FeS) are solids. Since solids have lower entropy compared to gases or liquids, the entropy of the system does not increase in this reaction. Option A

The reaction 3H₂(g) + N₂(g) → 2NH3(g) has an enthalpy of reaction of -92.6 kJ/mol. If 1 g of hydrogen and 2 g of nitrogen are
reacted, how much heat is produced (kJ)?

Answers

The amount of heat energy produced when 1 g of hydrogen and 2 g of nitrogen are reacted, is -6.61 KJ

How do i determine the heat energy produced?

First, we shall obtain the limiting reactant. Details below:

3H₂ + N₂ -> 2NH₃

Molar mass of N₂ = 28 g/molMass of N₂ from the balanced equation = 1 × 28 = 28 g Molar mass of H₂ = 2 g/molMass of H₂ from the balanced equation = 3 × 2 = 6 g

From the balanced equation above,

28 g of N₂ reacted with 6 g of H₂

Therefore,

2 g of N₂ will react with = (2 × 6) / 28 = 0.43 g of H₂

We can see that only 0.43 g of H₂ is needed in the reaction.

Thus, the limiting reactant is N₂

Finally, we the amount of heat energy produced. Details below:

3H₂ + N₂ -> 2NH₃ ΔH = -92.6 KJ

Molar mass of N₂ = 28 g/molMass of N₂ from the balanced equation = 1 × 28 = 28 g

From the balanced equation above,

When 28 grams of N₂ reacted, -92.6 KJ of heat energy were produced.

The empirical formula of the compound is C₂H₁₆S₂N₃O.

What is the empirical formula of the compound?

The moles of each element is as follows::

For CO₂:

Carbon (C) has a molar mass of 12.01 g/mol.

Oxygen (O) has a molar mass of 16.00 g/mol.

Moles of C in CO₂ = 2.08 g / 12.01 g/mol = 0.173 moles

Moles of O in CO₂ = 2.08 g / 16.00 g/mol = 0.130 moles

For H₂O:

Hydrogen (H) has a molar mass of 1.01 g/mol.

Oxygen (O) has a molar mass of 16.00 g/mol.

Moles of H in H₂O = 1.28 g / 1.01 g/mol = 1.27 moles

Moles of O in H₂O = 1.28 g / 16.00 g/mol = 0.080 moles

For SO₃:

Sulfur (S) has a molar mass of 32.06 g/mol.

Oxygen (O) has a molar mass of 16.00 g/mol.

Moles of S in SO₃ = 4.77 g / 32.06 g/mol = 0.149 moles

Moles of O in SO₃ = 4.77 g / 16.00 g/mol = 0.298 moles

For HNO₃:

Hydrogen (H) has a molar mass of 1.01 g/mol.

Nitrogen (N) has a molar mass of 14.01 g/mol.

Oxygen (O) has a molar mass of 16.00 g/mol.

Moles of H in HNO₃ = 3.48 g / 1.01 g/mol = 3.45 moles

Moles of N in HNO₃ = 3.48 g / 14.01 g/mol = 0.248 moles

Moles of O in HNO₃ = 3.48 g / 16.00 g/mol = 0.217 moles

The simplest whole-number ratio of the elements will be:

Carbon: 0.173 moles / 0.080 moles ≈ 2.16

Hydrogen: 1.27 moles / 0.080 moles ≈ 15.88

Sulfur: 0.149 moles / 0.080 moles ≈ 1.86

Nitrogen: 0.248 moles / 0.080 moles ≈ 3.10

A sample of 2.0 grams of helium gas is contained in a tank with a volume of 5.0 L at a temperature of 25° C. what is the pressure of the gas in the tank in atm?

Answers

To calculate the pressure of the helium gas in the tank, we can use the ideal gas law equation:

PV = nRT

where P is the pressure of the gas, V is the volume of the tank, n is the number of moles of the gas, R is the ideal gas constant, and T is the temperature of the gas in Kelvin.

First, we need to convert the temperature from Celsius to Kelvin by adding 273.15 to it:

T = 25°C + 273.15 = 298.15 K

Next, we need to calculate the number of moles of helium gas in the tank using its mass and molar mass:

n = m/M

where m is the mass of the gas and M is its molar mass. The molar mass of helium is approximately 4.00 g/mol.

n = 2.0 g / 4.00 g/mol = 0.50 mol

Now we can substitute the values we have into the ideal gas law equation and solve for P:

P = nRT/V

P = (0.50 mol)(0.08206 L·atm/(mol·K))(298.15 K)/(5.0 L)

P = 2.43 atm

Therefore, the pressure of the helium gas in the tank is approximately 2.43 atm.

Glucose, C6H12O6, is used to prepare intravenous feeding solutions. What volume of 5.0 % W/V glucose solution can be prepared using 125 g of glucose? Show your working.

Please if the answer is correct, ill give brainliest

Answers

250 L of 5.0% w/v glucose solution can be prepared using 125 g of glucose.

We use the below formula to solve our problem,

w/v = [ mass of solute (g) / volume of solution (mL) ] × 100

Substitute the values from our problem,

5.0 % w/v = [ 125 g / volume of solution (mL) ] × 100

Rearranging the formula, we have

volume of solution (mL) = [ 125 g / 5.0 % w/v ] x 100

Substitute further for w/v,

volume of solution (mL) = [ 125 g / (5.0 / 100) ] x 100

Simplify the expression,

volume of solution (mL) = [ 125 g / 0.05 ] x 100

Hence, the volume of solution (mL) = 250,000 mL or 250 L

To find the graph of the function g(x) = f(-x), we can start with the graph of the function f(x) and then reflect it about the y-axis.

If the graph of f(x) is symmetric with respect to the y-axis, meaning it is unchanged when reflected, then g(x) = f(-x) will have the same graph as f(x).

However, if the graph of f(x) is not symmetric with respect to the y-axis, then g(x) = f(-x) will be a reflection of f(x) about the y-axis.

In either case, the resulting graph of g(x) = f(-x) will be symmetric with respect to the y-axis.
