Answer:
B
Explanation:
For solving this we need a heat balance
By changing the corresponding relations, we have
By cancelling similar factor, we obtain
Which means that the change of temperature in A is twice the change of B
True! You can use the percentage to determine the amount of moles of each substance in the compound, and then use that information to find the empirical formula.
From the stoichiometry of the reaction, 1.4 * 10^-3 g is produced.
<h3>What mass of water is produced?</h3>
The equation of the reaction is written as; CO2 + 2LiOH → Li2CO3 + H2O. This can help us to apply the principle of stoichiometry here.
Thus;
Number of moles of CO2 = 0.00345 g/44 g/mol = 7.8 * 10^-5 moles
If 1 mole of CO2 produced 1 mole of water
7.8 * 10^-5 moles of CO2 produced 7.8 * 10^-5 moles of water
Mass of water produced = 7.8 * 10^-5 moles * 18 g/mol = 1.4 * 10^-3 g

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.
