<u>Answer:</u> The mass of water produced in the reaction is 47.25 grams.
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
.....(1)
Given mass of ammonia = 29.7 g
Molar mass of ammonia = 17 g/mol
Putting values in equation 1, we get:
The given chemical reaction follows:
By stoichiometry of the reaction:
4 moles of ammonia produces 6 moles of water.
So, 1.75 moles of ammonia will produce = of water.
Now, calculating the mass of water by using equation 1, we get:
Molar mass of water = 18 g/mol
Moles of water = 2.625 moles
Putting values in equation 1, we get:
Hence, the mass of water produced in the reaction is 47.25 grams.
<h2>0.2 atm </h2>
Explanation:
The new pressure can be found by using the formula for Boyle's law which is
Since we're finding the new pressure
We have
We have the final answer as
<h3>0.2 atm</h3>Hope this helps you
Answer:- Yes, strontum bromide and potassium sulfate gives a precipitate of strontium sulfate.
Explanations:- As per the solubility rules, all compounds of alkali metals are soluble.
Sulfate of most of the alkaline earth metals like Ca, Ba and Sr are insoluble.
A double displacement reaction takes place when strontium bromide and potassium sulfate are mixed and a precipitate of strontium sulfate is formed:
Note: (aq) stands for aqueous and (s) stands for solid and here it's precipitate.
