Answer:
because that is the last group the ones before it are more reactive im sorry if this not what you were looking for.
The given question is incomplete the options of the compete are:
A. On racecar tracks
B. In real-world conditions
C. In flooded environments
D. On closed courses
Answer: In real world conditions.
Explanation:
Fuel cell vehicles use hydrogen has as a fuel in order to run the car. Unlike the other conventional vehicle that run on fossil fuels and gasoline.
The hydrogen and oxygen combines together in order to power the the motor in the car. The electricity produced by the combination of this runs the car and the waste product is water.
They are also called as electronic cars but the main problem is that it has not been yet tested in the real world. There are many more physiological conditions that differ from place to place in the real world conditions.
Firstly, the cars needs to be tested in the real world and see where there are any advantages and disadvantages over conventional vehicles.
Hence, it is not available to the general public for purchase.
Because of the heat, steam
Answer:
hydrogen oxygen carbon and nitrogen
The molarity of 25.00 grams of powdered AgNO3 added to 500.00mL of pure water is 0.29 mol/L
<h3>Stoichiometry</h3>
From the question, we are to determine the molarity of the solution prepared.
First, we will determine the number of moles of AgNO₃ present.
Using the formula,
From the given information,
Mass = 25.00 g
Molar mass = 169.874 g/mole
Number of moles = 
Number of moles of AgNO₃ present = 0.147168 mole
Now, for the molarity of the solution
From the given information,
Volume = 500.00 mL = 0.5 L
Molarity = 
Molarity = 0.294336
Molarity ≅ 0.29 mol/L
Hence, the molarity of 25.00 grams of powdered AgNO3 added to 500.00mL of pure water is 0.29 mol/L
