Sample Response: The change in her position (from beginning to end), along with the direction, is considered her displacement. T

his value is a measurement and a direction. The total distance along the path from her starting point to her end point is considered her distance. This value is a measurement only. What did you include in your response? Check all that apply.

The sample response given in the question is right.

To find the answer, we need to know more about the distance and displacement.

<h3>How distance differ from displacement?</h3>
  • Displacement is the shortest distance between the initial and final points of a body.
  • It is the change in position with a fixed direction.
  • Displacement is a vector quantity and can be positive, negative or zero values.
  • Distance is the length of actual path of the body between initial and final positions.
  • It's a scalar quantity and it can be positive or zero.
  • The magnitude of displacement is less than or equal to the distance travelled.

Thus, we can conclude that the given sample response is right.

An aluminum block has a density of 2.70 g/mL. If the mass of the block is 24.60 g, find the volume of the substance.
harina [27]

Volume of a substance can be determined by dividing mass of the substance by its density.

That can be mathematical shown as:

Density=Mass/Volume

So, Volume=Mass/Density

Here mass of the substance given as 24.60 g

Whereas density of the substance is 2.70 g/mL

So,

Volume=Mass/Density

=24.6/2.7

=9.1 mL

So volume of the substance is 9.1 mL.

calcium has atomic number of 20 how many electrons of a calcium atom are involved in chemical bonding
Lelu [443]

The answer is 2 electrons.


The electron configuration of calcium is 2:8:8:2

Calcium has two electrons in its outermost shell. These are its valence electrons and are the ones used in bonding with other elements.  Valence electrons of an atom are those electrons that are in its outer energy shell or that are available for bonding.

Calcium is a metal. When metals react with non-metals, electrons are transferred from the metal atoms to the non-metal atoms forming ions. The resulting compound is known  as an ionic compound.

For example, when calcium metal reacts with chlorine gas,   calcium gives up its two valence electrons and Chlorine accepts them resulting in a new substance called calcium chloride in which the two elements have ended up forming ionic bonds.

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.
