Answer:
b. 1.5 atm.
Explanation:
Hello!
In this case, since the undergoing chemical reaction suggests that two moles of A react with one moles of B to produce two moles of C, for the final pressure we can write:
Now, if we introduce the stoichiometry, and the change in the pressure 
we can write:
Nevertheless, since the reaction goes to completion, all A is consumed and there is a leftover of B, and that consumed A is:
Thus, the final pressure is:
Therefore the answer is b. 1.5 atm.
Best regards!
Liquids stays the same volume but the bonds are spaced out enough that it can take the shape of whatever container it’s in.
Answer:
A3B3
Explanation:
Molecular formula = n x empirical formula
(AB) n = 90
MM of AB = 30 g/mol
30n = 90
Divide both side by the coefficient n i.e 30
n = 90/30 = 3
Molecular formula = n x empirical formula
Molecular formula = n x (AB)
Molecular formula = 3(AB) = A3B3
Answer: The faster stuff or an object moves, the more energy it has. ... Energy can be transformed from one way to another. Kinetic energy can be told apart from the various forms of potential energy. A demonstration is: toaster transforms electrical energy into thermal energy.
Explanation: An energy transformation is the change of energy from way to another. Energy transformations occur everywhere every second. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, and chemical. Because the law of conservation of energy states that energy is always conserved in the world and simply changes from one form to another, many energy transformations are taking place all the time
