The amount of energy that must be absorbed or lost to raise or lower the temperature of 1 g of liquid water by 1°C _____. See Concept 3.2 (Page)

Answers

Answer:

Specific heat capacity

Explanation:

Heat capacity is defined as amount of the heat supplied or absorbed by the given mass of the material so to make a unit change in the material's temperature.

The SI unit is Joule / kelvin (J/K).

It is an extensive property.

While,

Specific heat capacity is the amount of heat absorbed or lost by one gram of mass of the substance to raise it's temperature by 1°C or 1 K

It is an intensive property.

How is an average mass different from a weighted average mass?

Answers

The weighted average mass of the atoms in a naturally occurring sample of an element is the average atomic mass, also known as atomic weight.

What is atomic mass?

The average mass of an element's atoms expressed in atomic mass units is known as its atomic mass (amu, also known as daltons, D).

The mass of each isotope is multiplied by its abundance to produce the atomic mass, which is a weighted average of all the isotopes of that element.

Any element has a variety of isotopes, thus to take into consideration the fact that each isotope has a different mass, a weighted average mass is used.

A weighted average takes into account the potential that an element's average mass, as calculated from a random sample, will most likely coincide with the average mass of its more common isotopes.

The weighted average masswill therefore be closest to that of the more prevalent isotopes.

To learn more about Atomic mass, refer to the below link:

With any element, there are a range of isotopes . . . a weighted average mass is used because there exist different isotopes of that element, each of varying mass. A weighted average accounts for the fact that the average mass (that may likely be measured from a random sample of the element) will most likely reflect the average mass of the more abundant isotopes. So the weighted average mass will be most comparable to the more abundant isotopes.

What is ph?how basic a solution is
how acidic a solution is
the concentration of potassium ions in a solution
the concentration of hydrogen ions in a solution

Answers

I think the best option is the fourth statement. pH is the measure of the concentration of hydrogen ions in a solution. It is expressed as: pH = -log [H+]. However, it is also an indicator of the acidity and alkalinity of a solution.

Answer:

The concentration of hydrogen ions in a solution

Which atomic model states that it is impossible to know the exact location of electrons around the nucleus?

Answers

The correct answer is electron-cloud model. This model states that electrons don't go around in an eliptical way but rather completely erratically and uncontrolably and this is why it can't be known where they are or how they will behave. They form sort of like a cloud of many electrons that move erratically so you have to check it to see where it is.

Answer:

Electron -cloud model
