4 Al + 3 O₂ --> 2 Al2Ol₃ Given 6 moles of aluminum, how many grams of aluminum oxide will be produced?

Answers

Answer:

305.88 g

Explanation:

4 Al + 3 O₂ → 2 Al₂O₃

First, we convert 6 moles of aluminum (Al) into moles of aluminum oxide (Al₂O₃), using the stoichiometric coefficients:

6 mol Al * [tex]\frac{2molAl_2O_3}{4molAl}[/tex] = 3 mol Al₂O₃

Finally we convert 3 moles of aluminum oxide into grams, using its molar mass:

3 mol Al₂O₃ * 101.96 g/mol = 305.88 g

How many moles of steam are produced when 5.74 moles of octane (C8H18) react?

Answers

This is a combustion reaction, which always has the hydrocarbon and oxygen as reactants and then carbon dioxide and water (which is steam in this case) as products.

C8H18 + O2 —> CO2 + H2O

Balance your carbons first. You want to get 8 carbons on both sides.

C8H18 + O2 —> 8CO2 + H2O

Now balance your hydrogens. You want 18 hydrogens on both sides.

C8H18 + O2 —> 8CO2 + 9H2O

Now balance your oxygens. You have 2 on the left and 25 on the right. The O2 reactant needs a coefficient of 12.5 to balance this.

C8H18 + 12.5O2 —> 8CO2 + 9H2O

However, you can’t have decimals for coefficients in a reaction. So, multiply everything by 2.

2C8H18 + 25O2 —> 16CO2 + 18H2O

Now, use your mole ratio of 18 mol H2O for every 2 mol C8H18 to solve.

5.74 mol C8H18 • (18 mol H2O / 2 mol C8H18) = 51.7 mol H2O (steam)

HELP PLEASE ||Suppose you add water to a 6 g of sugar to make a solution with a concentration of 3 g/L. What is the total volume of the solution?

Answers

Answer:

2 L

Explanation:

Divide the mass by the concentration to find the volume.

(6 g)/(3g/L) = 2 L

According to the concept of solubility, in order to make solution of sugar the total volume of solution is 2 g/L.

What is solubility?

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

In order to calculate total volume of solution divide mass/ concentration that is 6/3=2 g/L.

Thus, the total volume of the solution is 2 g/L.

Calculate the change in heat (Q) that occurs when 38.68grams of steam at 304°C cools to liquid water at 197°C. (cp = 4.184 J/g°C)

Answers

Answer:

Change in heat (Q) = -1.7316 x 10⁴

Explanation:

Given:

Mass m = 38.68 g

Change in temperature Δt = (197-304) = -107°C

Specific heat C = 4.184 J/g°C

Find:

Change in heat (Q)

Computation:

Change in heat (Q) = (C)(m)(Δt)

Change in heat (Q) = (4.184)(38.68)(-107)

Change in heat (Q) = -1.7316 x 10⁴

What is the pH of a buffer solution prepared by mixing 20.0 mL of 0.0800 molL−1NaOH with 20.0 mL of 0.130 molL−1 cacodylic acid?

Answers

Answer:

pH = 6.20

Explanation:

The pKa of cacodylic acid is 6.

To solve this question we must use Henderson-Hasselbalch equation:

pH = pKa +log [A⁻] / [HA]

Where pKa is the pKa of the weak acid = 6

And [] could be taken as the moles of A⁻ the conjugate base, and HA, the weak acid.

The moles of the NaOH added to the solution of the weak acid are = Moles A⁻

And moles HA = Initial moles HA - Moles NaOH added

Initial moles HA:

0.0200L * (0.130mol / L) = 0.00260 moles

Moles NaOH:

0.0200L * (0.0800mol / L) = 0.00160 moles = [A⁻]

Moles HA =

0.00260 moles - 0.00160 moles = 0.00100 moles = [HA]

pH = 6 +log [0.00160 moles] / [0.00100 moles]

pH = 6.20

The pH of the resulting solution is 1.6.

Let cacodylic acid be HA, mixing cacodylic acid and NaOH, the following occurs;

HA(aq) + NaOH(aq) ------> NaA(aq) + H2O(l)

Number of moles of NaOH = 0.0800 molL−1 × 20.0/1000 = 0.0016 moles

Number of moles of HA = 20.0/1000  × 0.130 = 0.0026 moles

We can see that the HA is in excess, Number of moles of excess acid =

0.0026 - 0.0016 = 0.001 moles

Total volume of solution = 20.0 mL + 20.0 mL = 40 mL or 0.004 L

Molarity of excess acid =  0.001 moles/0.004 L = 0.025 M

pH = -log[H^+]

pH = -log[0.025 M]

pH = 1.6

Calculate the volume which 1.00 mole of a gas occupies at STP.

Answers

Answer:

22.4 L

Explanation:

A gas at STP will possess the following;

Pressure (P) = 1 atm

Temperature (T) = 273K

General gas constant (R) = 0.0821 Latm/molK

Using the general gas law formula to calculate the volume a gas of 1 mol will contain;

PV = nRT

V = nRT/P

V = 1 × 0.0821 × 273 ÷ 1

V = 22.41/1

V = 22.4 litres
