Calculate the mass of oxygen produced when 2000 kg of aluminium oxide is completely electrolysed.
Answer:
Explanation:
Given that:
The mass of aluminium oxide Al₂O₃ = 2000 kg = 2000 000 g
Molar mass of Al₂O₃ = 101.96 g/mol
no of moles = mass / molar mass
no of moles of Al₂O₃ = 2000 000 g/ 101.96 g/mol
no of moles of Al₂O₃ = 19615.4 mol
From the reaction:
4Al + 3O₂ ⇒ Al₂O₃
To determine the moles of O₂ in Al₂O₃:
Then;
19615.4 mol * 3/2 mol of O₂ = 29423.1
The mass of oxygen now = 29423.1 × 32 g
= 941539.2 g
To kg;
= (941539.2 / 1000) kg
= 941.5 kg

A mixture of gases with a pressure of 900 mm Hg contains 20% of oxygen and 80% of nitrogen by volumeWhat is the partial pressure of the oxygen gas in the mixture?
A-45mmHg
B-180mmHg
C-210 mmHg
D-320 mmHg
Answer:
180 mmHg
Explanation:
Total volume of gases = 20% + 80%= 100%
Total pressure of gases = 900 mm Hg
Note that partial pressure of a gas = mole fraction × total pressure
Mole fraction of oxygen = 20/100
Hence partial pressure of oxygen= 20/100 × 900 mm Hg
partial pressure of oxygen= 180 mmHg
when electrical energy is converted into any other deform of energy, the total amount of energy
A haloalkane 'X' if heated with sodium metal in presence of dry ether produces
2,3 - dimethyl butane
as major product
Identify x with chemical reaction.
Answer:
2 halo - propane
Explanation:
We are told that a halo alkane is heated with sodium in the presence of dry ether to produce 2,3 - dimethyl butane.
Now, according to Wurtz reaction this formation from heating with sodium in the presence of dry ether is done by 2 alkyl halides in the form of;
2RX + 2Na → R−R + 2Na+X−
Now, formula for 2,3 dimethyl butane is (CH₃)₂CHCH(CH₃)₂
Thus, from the Wurtz reaction, we can write that;
2RX + 2Na → (CH₃)₂CH - CH(CH₃)₂ + 2Na+X−
So, R = (CH₃)₂CH
This means the original halo alkane has 3 carbon atoms and thus, we can say it is 2 halo - propane.

How many grams H2 are needed to react with 2.80 g of N2?
Answer:
N2 +3 H2 → 2 NH3
so we have 2180 g of N2
or 2.80 g ÷ 28.02 g/mol = 0.100 mol
1 mol of N2 react with 3 moles of H2
Therefore 0.100 mol of N2 react with 0.3 moles of H2
0.300 mol X Molar mass (2.00 g/mol) = 0.600 g
0.600 g of H[tex]_2[/tex] are needed to react with 2.80 g of N[tex]_2[/tex]. Mole is one of the International System for Units' seven foundation units (SI).
What is mole?A mole is just a measuring scale. In reality, it is one of the International System for Units' seven foundation units (SI). When already-existing units are insufficient, new ones are created. Using absolute amounts of atoms, molecules, or ions would be problematic as well since chemical reactions frequently occur at levels that use grams would be inappropriate.
A mole consists of precisely 6.022140761023 particles. The "particles" might be anything, from tiny things like electrons and atoms to enormous things like stars or elephants.
N[tex]_2[/tex] +3 H[tex]_2[/tex] → 2 NH[tex]_3[/tex]
2.80 g ÷ 28.02 g/mol = 0.100 mol of N[tex]_2[/tex]
1 mol of N[tex]_2[/tex] react with 3 moles of H[tex]_2[/tex]
0.100 mol of N[tex]_2[/tex] react with 0.3 moles of H[tex]_2[/tex]
0.300 mol X Molar mass (2.00 g/mol) = 0.600 g of H[tex]_2[/tex]

10. mL of 0.10 M HCl(aq). The concentration of the NaOH(aq) is
Answer:
0.0286M
Explanation:
Using the formula as follows:
CaVa = CbVb
Where;
Ca = concentration of HCl acid (M)
Cb = concentration of NaOH base (M)
Va = volume of HCl acid (mL)
Vb = volume of NaOH base (mL)
According to the information provided in this question;
Ca = 0.10 M
Cb = ?
Va = 10mL
Vb = 35mL
Using CaVa = CbVb
Cb = CaVa/Vb
Cb = (0.10 × 10) ÷ 35
Cb = 1 ÷ 35
Cb = 0.0286M

7.68 x 4.564 = [?]
Answer: The correct number of significant figures in [tex]7.68 \times 4.564[/tex] is 35.05152.
Explanation:
Digits present in a number that helps in determining the degree of accuracy starting from the first non-zero digit is called a significant figure.
Some rules for significant figures are as follows.
All the digits present within the non-zero digits are considered in a number.For example, 2085 contains 4 significant digits.
Leading zeros are not counted in a number.For example, 0.0034 has 2 significant digits.
We count the trailing zeros when a decimal point is present in a number.For example, 0.02500 has 4 significant figures.
When there is no decimal point then trailing zeros may or may not count.For example, 19000 has 2 significant digits.
Now, the product of given digits is as follows.
[tex]7.68 \times 4.564 = 35.05152[/tex]
Thus, we can conclude that correct number of significant figures in [tex]7.68 \times 4.564[/tex] is 35.05152.

We must remember that when a constraint such as a change in concentration, pressure or temperature is imposed on a reaction system in equilibrium, the equilibrium position will shift in such as way as to cancel the constraint.
If more of A or more of B is added to the system, the equilibrium position will shift towards the right and the solution becomes clear and colorless.
If C is added to the system, the equilibrium position will shift towards the left and the solution colour turns blue.
If A is removed from the system, the equilibrium position is shifted towards the left and the solution once again turns blue.
If C is removed from the system, the equilibrium shifts towards the right and the solution turns clear and colorless
if 5.0g zinc reacts with 10.0 g hci to produce h2 gas and znci2 according to the following equation zn=2hci znci2 + h2 what is the limiting reactant and how many grams of h2 will be produced
Answer: The mass of [tex]H_2[/tex] produced is 0.153 g
Explanation:
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex] ......(1)
For zinc:Given mass of zinc = 5.0 g
Molar mass of zinc = 65.38 g/mol
Putting values in equation 1, we get:
[tex]\text{Moles of zinc}=\frac{5.0g}{65.38g/mol}=0.0765mol[/tex]
For HCl:Given mass of HCl = 10.0 g
Molar mass of HCl = 36.46 g/mol
Putting values in equation 1, we get:
[tex]\text{Moles of HCl}=\frac{10.0g}{36.46g/mol}=0.274mol[/tex]
The given chemical equation follows:
[tex]Zn+2HCl\rightarrow ZnCl_2+H_2[/tex]
By stoichiometry of the reaction:
If 1 mole of zinc reacts with 2 moles of HCl
So, 0.0765 moles of zinc will react with = [tex]\frac{2}{1}\times 0.0765=0.153mol[/tex] of HCl
As the given amount of HCl is more than the required amount. Thus, it is present in excess and is considered as an excess reagent.
Thus, zinc is considered a limiting reagent because it limits the formation of the product.
By the stoichiometry of the reaction:
If 1 mole of zinc produces 1 mole of [tex]H_2[/tex]
So, 0.0765 moles of zinc will produce = [tex]\frac{1}{1}\times 0.0765=0.0765mol[/tex] of [tex]H_2[/tex]
We know, molar mass of [tex]H_2[/tex] = 2 g/mol
Putting values in above equation, we get:
[tex]\text{Mass of }H_2=(0.0765mol\times 2g/mol)=0.153g[/tex]
Hence, the mass of [tex]H_2[/tex] produced is 0.153 g
