You have two water samples.

Chemistry
1 answer:
nikklg [1K]3 years ago
6 0

Answer:

  • <em>Sample X</em>, contains the most heat.

Explanation:

In thermodynamics, the <em>heat content</em> of heat of a system or a substance is described by the term enthalpy.

The heat content (enthalpy) is an extensive property, meaning that it is dependent on the amount of substance.

More substance more heat energy content.

Heat content is also related with the temperature. The higher the temperature the greater the kinetic energy and the higher the heat content.

Since, sample X and sample Y are both at the same temperature of 42°C, this variable does not differentiate the heat content of such samples.

Since, the sample X has more volume than sample Y, as per the previous conclusion that the more substance the more heat energy, you can certainly asses that the former contains the most heat.

Which of the following concerning the effects of temperature and pressure on solubility is/are correct?
just olya [345]

Answer:

None of the options are correct.

Explanation:

1) when the temperature of the solution is increased the solubility of the gas in the liquid decreases , hence option 1 is incorrect.

2)The heat released by the dissolution of an ionic compound in water is heat of hydration of the compound and is independent of the initial temperature of the solution.

3) The solubility of a liquid in water is not affected significantly by the pressure changes in the system as gases only have a significant cahne in solubility with change in pressure.

(b) What is the pOH of 1.35x10⁻³ M HCl? Is the solution neutral, acidic, or basic?
nika2105 [10]

The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7

<h3>What is pOH scale?</h3>

Based on the relative concentration of hydrogen and hydroxyl ions, the pH and pOH scales are used primarily in chemistry, biology, and soil science to describe and measure the acidity and basicity of neutral, acidic, and basic solutions in water.

The terms pH and pOH scale are frequently used and crucial for determining the chemical, biological, and soil health by converting the values of hydrogen or hydroxyl ion concentrations or by utilizing pH paper and meters.

The pH scale or chart, which measures the concentration of hydrogen and hydroxyl ions in acidic and alkaline solutions, was initially developed by Sorensen.

HELP ASAP!! how can nuclear energy be classified as an inexhaustible energy resource??
seropon [69]

Answer:

No, and yes. As there is a finite amount of matter in the

universe, only so much can be converted to make energy. There will

be a limit, though it is a long, long way from where we are
