3 Cu + 8HNO3 --> 3 Cu(NO3)2 + 2 NO + 4 H20 In the above equation how many moles of water can be made when 60 moles of HNO3
are consumed?

30 mols of water.

Explanation:

This really does not require that you do any calculations but a short one in your head.

8 mols of HNO3 > 4 mols of water.

In other words all you need do is divide the number of mols of HNO3 by 2

60 mols of HNO3 will produce 30 mols of water. If you have a teacher who is a slave to more formal ways of things,, then set up a proportion.

8 HNO3 / 4 H2O > 60 mols HNO3 / x mols water

8/4 ===> 60 / x            Cross Multiply

8x = 4*60                     Combine the right

8x = 240                       Divide by 8

8x/8 = 240/8

x = 30

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
