Which of the elements has the same lewis structure as sulfur?

professor190 [17]

The answer is Oxygen. The elements that has the same lewis structure as sulfur is Oxygen. This is due to the fact that although the two compounds have different electronic configurations, the two have the same arrangement of electrons in their outermost orbits.

SEP Analyze Data Use graphing software or draw a graph from the data in the table. Label "Heat input (joules)" on the y-axis and

galben [10]

The characteristics of the graphic representation are to find the scales and make the best graphic, in the attachment we have the points plotted

The graphical representation is one of the best methods to see the relationships between groups of data and to be able to find the functional relationships between them.

In this case, it is requested to make a scatter plot where the measured temperature is placed on the x-axis and the heat on the y-axis.

In the attachment we can see a graph with the requested data, the most important part of finding these graphs is looking for the scales

x-axis

scale x = $\frac{\Delta Values}{paper length}$

y-axis

scale y = $\frac{\Delta Values}{paper \ lengthy}$

In general, the paper is 20 x 30 cm, we select the shortest part as the x axis

scale x = $\frac{50-30}{20}$

scale x = 1º $\frac{ C}{cm \ peper}$

Let's find the scale on the axis and the maximum value is 54000 and the minimum value is 3800, as the minimum value is much less than the maximum value, let's set this value to zero

scale y = $\frac{54000-0}{30}$

scale y = 1800 $\frac{j}{cm \ paper}$

To facilitate marking the values, we select a slightly larger scale,

Selected scale

scale y = 2000 \frac{j}{cm \ paper}

Let's mark the points.

From observing these graph we see;

The relationships are linear
For the same material the amount of heat necessary to reach the same temperature is proportional to the mass of the material

Using the characteristics of the graphical representation, it is possible to find the scales and make the best graph

What units do chemists normally use for the density of liquids and solids? For the density of gas? Explain the differences.

beks73 [17]

Answer:

Densities of the solids and the liquids are expressed in units of grams per cubic centimeter (g/cm³) or in grams per milliliter (g/mL).

Densities of the gases are usually expressed in the units of grams per liter (g/L).

Explanation:

Density of a substance can be defined as the ratio of its mass and its volume.

The constituting atoms in the solids and liquids are fairly packed closely together.

In general, a 1 cm³ or 1 mL volume of most of the solids and the liquids has mass of several grams. Thus, densities of the solids and the liquids are expressed in units of grams per cubic centimeter (g/cm³) or in grams per milliliter (g/mL).

The constituent atoms or the molecules in the gases are far apart from each other when compared to the solids and the liquids.

Thus, gases are much less dense and even about 1 L of gas have mass in range close to 1 gram. Thus, densities of the gases are usually expressed in the units of grams per liter (g/L).

Also, the density of the gases also depend upon the pressure and the temperature but these factors much not influence the density of the solids and the gases.
