Which scatterplot shows the correct division for using the Divide-Center of Data method to draw the trend line?
1 answer:
The appropriate scatter plot that depicts the correct division for using Divide center to draw trend line is the plot D.
<h3>What are Scatter plots?</h3>Scatter plots are used to show how much one variable affects another by plotting data points on a horizontal and vertical axis. Each row in the data table is represented by a marker, the position of which is determined by the values of the columns set on the X and Y axes. Scatter plots are graphs that show the relationship of two variables in a data set. It is a two-dimensional plane or a Cartesian system that represents data points.
In order to draw a trend line correctly, divide the points using the divide center method. The dividing vertical line must be drawn at the midpoint (a position where the number of data points to the left and right of the vertical line is equal).
Only option D has a vertical line dividing the 6 data points into two equal portions when the options are evaluated based on this condition.

The correct answer choice is CO₂ (B)
Rainwater naturally contains acids derived from carbon dioxide in the air and reacts with water vapor to form weak acids
H₂O + CO₂ ---> H₂CO₃
<h3><em>Further Explanation</em></h3>Rainwater can cause damage to buildings, animals or plants due to acid rain
Acid rain occurs because other gases in the air mix with toxic gases to form acids
Rainwater naturally contains acids derived from carbon dioxide in the air and reacts with water vapor to form weak acids
H₂O + CO₂ ---> H₂CO₃
However, due to exhaust gases from industry, motor vehicles, or power plants that use fossil fuels containing sulfur to produce sulfur dioxide gas which will produce sulfuric acid
Sulfur combustion from fossil fuels
S + O₂ ----> SO₂
SO₂ produced from this exhaust gas reacts with O₂ oxygen which oxidizes SO₂ to SO₃
SO₂ + O₂ ----> SO₃
SO3 formed reacts with water vapor in the air to produce sulfuric acid as acid rain
SO₃ + H₂O ---> H₂SO₄
To reduce the pollution from this fossil fuel, various studies are now carried out as substitute energy that is more environmentally friendly such as solar energy and so on

<u>Answer:</u> The expression for equilibrium constant is
<u>Explanation:</u>
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
For the general chemical equation:
The expression for is given as:
For the given chemical reaction:
The expression for is given as:
The concentration of solid is taken to be 0.
So, the expression for is given as:
