Graphing is an important procedure used by scientist to display the data that is collected during a controlled experiment. There

astraxan [27]

Bar graph or bar chart displays data graphically using bars

The correct values are;

1. The independent variable is the month of the year

2. The dependent variable is the number of deer

3. The title is: The number of deer counted per month

The reason the above values are correct are as follows:

In a tabular form is given as follows;

$\begin{array}{|c|cc|}Month&&\# \ of \ deer \\Sept&&38\\Oct&&32\\Nov&&26\\Dec&&20\\ Jan &&15\\Feb&&12\end{array}\right]$

A. Please find attached the required bar graph (chart) created with a desktop application

1. In an investigation to assign the cause of an effect is the cause of an effect, the independent variable is the causal variable responsible for the observed effect, and it is not affected by the effect. It is the variable that is not measured

In the given data, the month of the year is not affected by the number of deer, and it is not counted, to see if there is a change, therefore, the independent variable is the month of the year

2. The dependent variable, is the effect variable that is measured, and it depends on the dependent variable, which is the month

Therefore, the dependent variable is the number of deer

3. An appropriate title is one that captures the information intended to be obtained from the Bar graph

An appropriate title for the bar graph is; The number of deer counted per month

Given the balanced equation representing a reaction:

GrogVix [38]

As aluminium loses 12 moles of electrons oxygen gain 12 moles of electrons.

Explanation
4Al + 3 O2→ Al2O3
first write the ions of Aluminium and oxygen

that is, Aluminium ion is = Al^3+
oxygen ion is = O^2-
therefore one atom of Al loses 3 electrons moles while
one atom of O gain 2 electrons moles

from equation above there a total of number of Al atom are 4 =( 1 x4=4) atoms while
Oxygen atoms are 6= ( 3 x2=6) atoms

therefore the total number of Moles of Al lost is = 3 x 4 = 12 moles of electrons

total number of moles of O gained = 2 x6 = 12 moles of electrons

You are performing a gradient elution and are instructed to begin with a low polarity solvent (petroleum ether) and continue to

Sophie [7]

Answer:

The eluting strength of a solvent is primarily related to how strongly it adsorbs onto the adsorbent and because typical adsorbents are highly polar; thus, eluting strength increases with solvent polarity.

Explanation:

The polarity of a solvent makes it more suitable for elution in a polar adsorbent. Hence the choice of solvents should be in order of increasing rather than decreasing polarity. polarity must increase and not decrease
