Answer: 19kpa
Explanation:
The total pressure of a mixture of gases is the sum of the partial pressure exacted by the individual gases.
P total = P X + P Y
From the question above:
P total = P .nitrogen + P. oxygen
123.5kpa = 104.5kpa + P. Oxygen
P. Oxygen = 123.5kpa - 104.5kpa
= 19kpa
Answer:
In its pure form, it is a very pale blue liquid, slightly more viscous than water. Hydrogen peroxide is the simplest peroxide (a compound with an oxygen–oxygen single bond).
Answer:oxidation number H = +1
oxidation number O = -2
let x = oxidation number Cl
in HClO3
+1 + x -6 =0
x = +5
Explanation:
Answer:

Explanation:
Given that the volume is 
The air flows (F) at the rate of
. The concentration of carbon monoxide in the air is 5%.
Let Q be the amount of the carbon monoxide present in the room at time t. then,

Also,


Thus,

Theses can include the power supply circuit a joule meter to measure the energy transferred which makes the calculations a lot easier.
