The largest mass silver chloride is precipitated when excess silver ions are added to 30.0cm3 of 0.30M iron(III) chloride solution.
<h3>What is a precipitation reaction?</h3>
A precipitation reaction is a reaction in which an insoluble substance is obtained when two solutions are mixed together as a result of one of the products of the reaction being insoluble in water.
Silver chloride is an insoluble salt that will precipitate when a single silver salt is added to a soluble chloride salt.
In the above, the largest mass silver chloride is precipitated when excess silver ions are added to 30.0cm3 of 0.30M iron(III) chloride solution since iron (iii) chloride is a weak electrolyte.

Answer:
34 g of NH₃ were produced in the reaction
Explanation:
N₂ (g) + 3H₂ (g) → 2NH₃ (g)
Moles of N₂ → 28 g / 28 g/m = 1 mol
Moles of H₂ → 25g / 2 g/m = 12.5 moles
Clearly, the limiting is the nitrogen.
1 mol of N₂ produced 2 moles of ammonia
So, If I have 1 mol, I'll produce the same amount
2 moles of NH₃ = Mol . Molar mass
2 m . 17 g/m = 34 g
The easiest way to approximate ph level is through the ph paper measurement system because using pH paper would be best for doing a quick measurement in the field. It does not essentially need to be calibrated or standardized and the papers make available an instant estimate.
Answer:
Explanation:
Evaporation is inhibited by high humidity. Low humidity is as result of hotter temperatures that is temperature when the cup of water is under the sun and vice versa for high humidity.
Relative humidity defined as the amount of water vapor in the surrounding air compared with the maximum possible. At its maximum which is termed saturation, relative humidity is 100% and evaporation is inhibited.
The amount of water vapor the air can hold depends on its temperature. Relative humidity rises at low temperatures for example in an air conditioned environment. As the air temperature declines, sometimes reaching the dew point relative humidity is 100%, and fog may result from the condensation of water droplets if they are small enough to stay in suspension.
Drying is more effective with hot air rather than cold air, because hot air can hold more water vapor. The capacity of air to hold water vapor is based on vapor pressure of water. The liquid and solid phases are continuously giving off vapor because some of the molecules have high enough speeds to enter the gas phase.
Therefore, a cup of water placed in the sun will have a reduced water level compared to that in an air conditioned room.
