Answer: Well isn't it supposed to be in YOUR own words not someone else's.?.?.
Explanation:
It has 4 because electrons are negative.
The balance chemical equation is as follow,
2 Al + 3 O₂ → Al₂O₃
Aluminium is the Limiting Reagent,
As,
107.92 g Al required = 96 g of O₂
Then,
82.49 g of Al will require = X g of O₂
Solving for X,
X = (82.49 g × 96 g) ÷ 107.92 g
X = 73.37 g of O₂
But,
We are provided with 117.65 g of O₂, So, it is provided in excess and 44.28 g of it will remain unreacted.
Solving for Amount of Al₂O₃ formed,
As,
107.92 g of Al produced = 203.92 g of Al₂O₃
Then,
82.49 g of Al will produce = X g of Al₂O₃
SOlving for X,
X = (82.49 g × 203.92 g) ÷ 107.92
X = 155.86 g of Al₂O₃
Answer:
- <em>The partial pressure of the oxygen gas is </em><u>96.00 KPa</u>
Explanation:
The law of partial pressures states that, in a mixture of gases, the total pressure of the mixture is equal to the sum of the individual pressures of each gas, as if each gas were alone in the mixture.
So:
- Total pressure = ∑ individual pressures
- Total pressure = Partial pressure of the water + Partial pressure of oxygen
- 98.67 KPa = 2.67 KPa + Partial pressure of oxygen
- Partial pressure of oxygen = 98.67 KPa - 2.67 KPa
- Partial pressure of oxygen = 96.00 KPa ← answer
Answer:
Some serious diseases like anthrax is also caused in animals by the microbes. Microbes also cause diseases of plants like blights in potatoes, sugarcanes, oranges etc. They also reduce the yield. Microbes grow on food products and render them unfit for consumption.
