5. Find the molality if 2.3 moles of glucose is dissolved in 500.0 g of water.

The molality is 4.6

Explanation:

Molality (m) is a concentration measurement that indicates the number of moles of solute that are dissolved in 1 kilogram of solvent.

The Molality of a solution is determined by the following expression:

The molality is expressed in units ().

In this case:

Replacing:

Solving:

Molality=4.6

The molality is 4.6

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

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.
