When will the net enthalpy of formation of a solution (δhsolution) be endothermic?

Chemistry
1 answer:
Gre4nikov [31]4 years ago
3 0
Answer is: i<span>t can be endothermic when the amount of energy needed to break the intermolecular forces in the solute is larger than the amount of energy given off by formation of intermolecular forces in the mixture, so solution must be heated.
In ideal solution </span><span> the forces of attraction between the solute-solute and the solvent-solvent and solute-solvent molecules are the same.</span>

assume the given amount of rbf fully dissociates in water. calculate the molarity of a solution if 124.86 g of rbf are dissolved
xeze [42]

Molarity of a solution if 124.86 g of rbf are dissolved into a solution of water that has a final volume of 2.00L is 0.59.

<h3>What is molarity?</h3>

Molarity is used for dilute aqueous solutions held at a constant temperature. In general, the difference between molarity and molality for aqueous solutions near room temperature is very small and it won't really matter whether you use a molar or molal concentration.

MOLARITY = no of moles of solute/volume of soln in litres

No of moles of rbf = 124.6/104.46

= 1.19

Volume of soln = 2

Molarity=1.19/2 = 0.59

Carbonic acid dissolves limestone and other rocks. This is an example of _____. chemical errosion
Jet001 [13]

Carbonic acid dissolves limestone and other rocks. This is an example of chemical erosion. An example is in the caves. Caves are formed where rainwater as it falls through the atmosphere absorbs carbon dioxide. The carbon dioxide makes the rain acidic to react it with the limestone bedrock. The rainwater is absorbed by the soil into the ground. Then as it enters through the soil, the rainwater will absorb more carbon dioxide that is produced by the decomposers. The carbon dioxide with water reacts to form carbonic acid. The carbonic acid will react to limestone and dissolves it slowly. As the space become larger, water can enter into it.

In order to design an experiment, you need a ____ about the scientific question you are trying to answer. A. decision B. procedu
kolbaska11 [484]

The correct answer is option C, that is, hypothesis.  

The hypothesis is the starting building block in the scientific method. It is also illustrated as an educated guess, based on previous observation and knowledge. A hypothesis refers to a recommended solution for an unexplained event, which does not fit into the present accepted scientific theory.  

The fundamental concept of a hypothesis is that there is no pre-determined result. For a hypothesis to be considered as scientific hypothesis, it has to be something, which can be refuted or supported via carefully crafted observation or experimentation.
