The partial pressure of CO is 0.536 atom.
<h3>Further Explanation</h3>
Dalton's Law of Partial Pressure states that the total pressure of a mixture of non-reacting gases is equal to the sum of the partial pressures of the individual gases. Mathematically, it can be represented as follows:
If the total pressure is known as well as the number of moles of the gases in the mixture, the partial pressure of a component as can be calculated using the equation below:
where:
Pₓ is the partial pressure of gas X
P(total) = total pressure of the mixture
nₓ = number of moles of gas X
n(total) = total number of moles of gas
To solve the problem, first sort the given:
- n(total) = 0.220 mol CO + 0.350 mol F₂ + 0.640 mol He = <u>1.21 moles</u>
- n(CO) = 0.220 mol
- P(total) = 2.95 atm
Then we plug in the given values into the equation above:

Explanation:
Young babies need a lot of calcium because calcium makes bones strong ,it protects them against bone loss in future,and it also prevents them from a disease called rickets.
Mixing equal amounts of a strong acid with a strong base also produces a neutral pH (pH = 7) solution<span>.

Answer:
A
Explanation:
An element is a substance that cannot be broken down into simpler substances using ordinary chemical procedures. To disintegrate an element, procedures like nuclear reactions needed to be used.
In fact, it was thought of that the elements are indivisible during the days of Dalton, but advances in science and technology has shown that these elements could be broken down albeit not easily
Answer:
Gold
Explanation:
We are given that
Mass of sample ,m=385 g
Volume ,V=20mL
We have to find the coin is gold or yellow brass.
We know that
Density=
Using the formula
Density of coin=19.3g/mL
Density of gold=19.3g/mL
Hence, the coin is gold.
