Fe2O3 (s) + 2 Al (s) ---> 3 Fe (l) + Al2O3 (s) Based on the thermite reaction, how much aluminum oxide (Al2O3) is formed from 8.0 grams of aluminum (Al)?

Answers

Answer:

15.3 g

Explanation:

Fe₂O₃ (s) + 2Al (s) → 3Fe (l) + Al₂O₃ (s)

First we convert 8.0 grams of aluminum into moles, using its molar mass:

8.0 g Al ÷ 27 g/mol = 0.30 mol Al

Then we convert 0.30 moles of aluminum into moles of aluminum oxide, using the stoichiometric coefficients:

0.30 mol Al * [tex]\frac{1molAl_2O_3}{2molAl}[/tex] = 0.15 mol Al₂O₃

Finally we convert 0.15 moles of Al₂O₃ into grams, using its molar mass:

0.15 mol Al₂O₃ * 102 g/mol = 15.3 g Al₂O₃

3.3 mol Fe(OH)3 and 6.3 mole H2SO4react according to the equation 2Fe(OH)3 + 3H2SO4 → Fe2(SO4)3 + 6H2O.
If the limiting reactant is Fe(OH)3, determine the amount of excess reactant that remains. Answer in units of mol.

Answers

Answer and Explanation:

2 mol of Fe(OH)3 produces 1 mol of Fe2(SO4)3  then 2.1 mol of Fe(OH)3 will produce (1)/(2) x 2.01 = 1.05 mol of Fe2(SO4)3  amount of H2O = (6)/(2) * 2.01 = 6.03 mol HO2

How many moles of gas are contained in a 50.0 L cylinder at a pressure of 100.0 atm and a temperature of 35.0°C?

Answers

Answer:

n = 2 moles (1 sig-fig)

Explanation:

Using the Ideal Gas Law equation (PV = nRT), solve for n (= moles) and substitute data for ...

pressure = P(atm) = 100atm

volume =V(liters) = 50L

gas constant = R = 0.08206L·atm/mol·K

temperature = T(Kelvin) = °C + 273 = (35 + 273)K = 308K

PV = nRT => n = PV/RT = (100atm)(50L)/(0.08206L·atm/mol·K)(308K)

∴ n(moles) = 1.978moles ≅ 2 moles gas (1 sig-fig) per volume data (= 50L) that has only 1 sig-fig. (Rule => for multiplication & division computations round final answer to the measured data having the least number of sig-figs).

Moles are the ratio of the mass and the molar mass of the substance. In a 50.0 L cylinder, 2 moles of gas are present at 100 atm and 35 degrees celsius.

What is an ideal gas equation?

An ideal gas equation states the relationship between the moles of the substance, temperature, pressure, and volume. The ideal gas equation is given as,

[tex]\rm PV = nRT[/tex]

Given,

The pressure of the gas (P) = 100.0 atm

Volume of the gas (V) = 50.0 L

Temperature (T) = 308 K

Gas constant (R) =  0.08206 L atm/mol K

Substituting values in equation moles (n) is calculated as:

[tex]\begin{aligned} \rm n&= \rm \dfrac{PV}{RT}\\\\&= \dfrac{100 \times 50}{0.08206 \times 308}\\\\&= 1.978\end{aligned}[/tex]

Therefore, 1.978 or 2 moles of gas are present.

What is the mass in grams of 0.94 moles of sodium bicarbonate. NaHCO3?​

Answers

Mass of a substance = Moles of a substance × molar mass of a substance

We have 0.94 moles of NaHCO3. The molar mass of NaHCO3 is the sum of the atomic masses of the elements comprising NaHCO3, which is approximately 84.007 g/mol.

The mass of 0.94 moles of sodium bicarbonate is therefore (0.94 moles NaHCO3)(84.007 g NaHCO3/mol NaHCO3) = 78.97 ≈ 79 grams of sodium bicarbonate.

While studying meiosis and mitosis for her genetics test, Marisa made notes of the kinds of cells produced from these processes with examples from the body. Which pairing of the cell produced during meiosis and example is correct?

A) diploid cell: liver cell

B) diploid cell: sperm cell

C) haploid cell: egg cell

D) haploid cell: hair cell

Answers

Answer:

C

Explanation:

The pairing of the cell produced during meiosis and correct example is haploid cell: egg cell (Option C).

A haploid (n) cell contains only a set of homologous chromosomes, whereas a diploid (2n) cell contains two sets of homologous chromosomes.

Meiosis is a type of reductional cell division by which a parental diploid (2n) cell generates four haploid germinal (egg) daughter cells having half of the genetic material.

Conversely, mitosis is a type of cell division that produces two genetically identical daughter cells.

Meiosis produces germinal (sex) cells, whereas mitosis produces somatic (body) cells.

In conclusion, the pairing of the cell produced during meiosis and correct example is haploid cell: egg cell (Option C).

convert kilometers to AU? (Hint: 1 AU = 149,598,000 km)

Answers

Answer:

Multiply the length value by 6.68456e-9

Explanation:

The question involves converting from one unit (kilometers) to another unit (Au)

From the question;

149,598,000 km = 1 AU

1 km = x

Cross multiplying;

1  * 1 = x * 149,598,000

1 = 149,598,000x

x = 1 / 149,598,000

x = 6.68456e-9

To convert kilometer to Au; Multiply the length value by 6.68456e-9

Determine the final temperature of a mixture of 50 grams of water at 10 C added to 120 grams of water at 80 C. Show all work. Use the simulator to check your answer. (Hint: This is a weighted average.)

Answers

Answer: 59.41

Explanation:

The final temperature of the system has been 130[tex]\rm ^\circ C[/tex].

Specific heat can be defined as the amount of heat required to raise the temperature of 1 g of substance by 1-degree celsius.

The amount of heat lost and the heat gained have been equal.

Heat = mass × specific heat × change in temperature

Thus,

mc[tex]\Delta[/tex]T = mc[tex]\Delta[/tex]T

50 g × (10 - x) = 120 × (x - 80)

500 - 50x = 120x - 9600

70x = 9100

x = 130

Calculate the number of moles of NaOH contained in 250. mL of a 0.05M solution.

Answers

Answer:

0.0125mol

Explanation:

Molarity (M) = number of moles (n) ÷ volume (V)

n = Molarity × Volume

According to this question, a 0.05M solution contains 250 mL of NaOH. The volume in litres is as follows:

1000mL = 1L

250mL = 250/1000

= 0.250L

n = 0.05 × 0.250

n = 0.0125

The number of moles of NaOH is 0.0125mol.

Answers

Answer:

its B) Thermohaline currents  Sorry if its wrong but im sure this could be it

Explanation:These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice.

Thermohaline currents deep-sea currents that occur because of differences between the salinity and temperature characteristics of water masses

What is thermohaline currents?

Thermohaline currents is also known as 'the ocean conveyor belt' or 'the global conveyor belt'. It is a part of the large scale ocean circulations.

As the name thermohaline suggested that, 'thermo' means heat and 'haline' refers to the salt content. So, when there is a great difference in the temperature and the salt content deep sea currents occur.

Hence option (2) is correct i.e. thermohaline currents occur due to temperature and salinity difference.
