It is 4/10 of moles is this ane halp?
The reason wet clothes spread out dry faster than when left in a pile is because there is more surface area therefore the rate of evaporation increases and this decreases the time it takes for the water molecules to diffuse into the air.
Answer:
HNO₃ (aq) —> H⁺ (aq) + NO₃¯ (aq)
Explanation:
From the question given above
HNO₃ + H₂O —> ?
Nitric acid, HNO₃ reacts with water, H₂O to form aqueous solution of nitric acid as illustrated below:
HNO₃ + H₂O —> HNO₃ (aq)
Nitric acid is a strong acid and, so will ionised completely when dissolved in water. This is illustrated below:
HNO₃ (aq) —> H⁺ (aq) + NO₃¯ (aq)
<u>Answer:</u> The mass percent of water in the original air sample is 4.16 %
<u>Explanation:</u>
We are given:
Volume of moist air = 12.0 L
Volume of dry air = 11.50 L
Volume of water lost = (12.0 - 11.50) L = 0.50 L
Here, the percent by mass ratio will be equal to the percent by volume ratio as the number of moles is directly related to the volume.
To calculate the volume percentage of water in the air, we use the equation:
Putting values in above equation, we get:
Hence, the mass percent of water in the original air sample is 4.16 %
Answer:
Extensive Properties
Explanation:
A physical property that will change if the amount of matter changes. Change in which the matter's physical appearance is altered, but composition remains unchanged. Solid is distinguished by a fixed structure. Its shape and volume do not change.
