Answer:
P(total) = 978 mmHg
Explanation:
Given data:
Total pressure of gas = ?
Partial pressure of O₂ gas = 200 mmHg
Partial pressure of N₂ gas = 350 mmHg
Partial pressure of He gas = 428 mmHg
Solution:
According to Dalton law of partial pressure,
The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.
Mathematical expression:
P(total) = P₁ + P₂ + P₃+ ............+Pₙ
P(total) = P(O₂) + P(N₂) + P(He)
P(total) = 200 mmHg + 350 mmHg + 428 mmHg
P(total) = 978 mmHg
I think it's oxide and halide
i don't know sorry ..............
The following are hazards of corrosion and rancidity;
1. There's reduction of efficiency of the metals.
2. It can lead to contamination especially in the pipes.
3. These can lead to financial losses brought by the destruction of metals.
4. It could result in pollution as a result of chemical reaction bringing about corrosion.
Radio waves. A cell phone transmits its signal to the towers by <em>electromagnetic waves</em>.
The electromagnetic waves are in the <em>radiofrequency region</em> of the electromagnetic spectrum.
Most cell phones in North America use radiofrequencies between <em>700 MHz and 850 MHz</em> and between <em>1700 MHz and 2500 MHz</em>.
