Answer:
4.59 grams of hydrogen
Explanation:
57.010 g of ammonium phosphate * 1 mol / 149 g of ammonium phosphate * 12.0 g H * / 1 mol = 4.591409396.
But with sig figs, it rounds to 4.59.
So the final answer is 4.59 grams of hydrogen.
Answer:
0.29
Explanation:
Step 1: Write the balanced equation at equilibrium
3 NO₂(g) + H₂O(l) ⇄ 2 HNO₃(aq) + NO(g)
Step 2: Calculate the molar concentration of the substances
We will not calculate the molarity of H₂O because pure liquids are not included in the equilibrium constant. We will use the following expression.
Molarity = mass of solute / molar mass of solute × liters of solution
Since the volume of the vessel is missing, we will assume it is 1 L to see the procedure.
[NO₂] = 22.5 / 46.01 g/mol × 1 L = 0.489 M
[HNO₃] = 15.5 g / 63.01 g/mol × 1 L = 0.246 M
[NO] = 16.6 g / 30.01 g/mol × 1 L = 0.553 M
Step 3: Calculate the value of the equilibrium constant Kc for this reaction
Kc = [HNO₃]² × [NO] / [NO₂]³
Kc = 0.246² × 0.553 / 0.489³
Kc = 0.29
Answer:
Mass of 
produced = 32 g
Explanation:
Calculation of the moles of 
as:-
Mass = 82.4 g
Molar mass of = 122.55 g/mol
The formula for the calculation of moles is shown below:
Thus,
From the reaction shown below:-
2 moles of potassium chlorate on reaction forms 3 moles of oxygen gas
So,
0.67237 moles of potassium chlorate on reaction forms 
moles of oxygen gas
Moles of oxygen gas = 1 mole
Molar mass of oxygen gas = 32 g/mol
<u>Mass of produced = 32 g</u>
Answer:
The precipitation reaction is the double displacement reaction in which two ionic bonds combine forming up insoluble salts.
Precipitation reaction can be used in our daily life in events such as in waste water treatment. When a contaminant forms an insoluble solid, then we can use this reaction to precipitate out the contaminated ions.
The rings which form in the bathtubs are also an example of the precipitation reactions.
Answer:
Your answer is b
Explanation:
the answer is b because if there is no phytoplankton then there will be no fish and if you take out one part of the food chain then the whole chain comes apart. So meaning if there is no phytoplankton, then there is no fish, if there isn't any fish, then the other animals that come to eat at the river will eventually starve to death or move somewhere else to get more food.
