The presence of hydrogen and hydroxyl ions determines the acidic and basic nature of a solution.

<h3>What determine acidic and basic nature of a solution?</h3>

The use of the pH scale is one way of determining the acidic and basic nature of solution. If the pH of a solution is less than 7, it is considered as acidic and if the pH is 7, the solution is neutral.

While if the pH is greater than 7,the solution is basic so we can conclude that the presence of hydrogen and hydroxyl ions determines the acidic and basic nature of a solution.

Bar graph or bar chart displays data graphically using bars

The correct values are;

1. The independent variable is the <u>month</u> of the year

2. The dependent variable is the <u>number of deer</u>

3. The title is:  <u>The number of deer counted per month</u>

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 <u>month</u> 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 <u>number of deer</u>

<u></u>

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; <u>The number of deer counted per month</u>

Clo3− draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons. Show t
Karo-lina-s [1.5K]

The formal charges of all nonhydrogen atoms are -1.

Solution:-

<u>O 7-4 = 3 O Double bond on one H 5-4 = 1</u>

O-Cl-O 6-7 = -1x4 = -4 N 5-4=1 H-N-H 1-1=0

O 3-4= -1 O O 6-7 = -1(2)=-2 H 1-0=+1

<u>6-6 = 0 1-2 = -1</u>

It will percentage its last valence electron thru a single bond to the terminal oxygen atom. This is in agreement with carbon and hydrogen atoms that each need to form 4 and 1 covalent bonds respectively. because the terminal oxygen atom best has a single covalent bond, it'll have a proper rate of -1.

According to the lewis structure of SO2, The critical atom is sulfur and it is bonded with 2 oxygen atoms thru a double bond. each oxygen atom acquires 2 lone pairs of electrons and the primary sulfur atom has 1 lone pair of electrons.

kirill [66]
<span>Answer: A 0.04403 g sample of gas occupies 10.0-mL at 289.0 K and 1.10 atm. Upon further analysis, the compound is found to be 25.305% C and 74.695% Cl. What is the molecular formula of the compound? --------------------------------------... Seems like I did a problem very similar to this--this must be the "B" test. But the halogen was different. 25.305% C/12 = 2.108 74.695% Cl/35.5 = 2.104 So the empirical formula would be CH. However, there are many compounds which fit this bill, so we have to use the gas data. (And I made, in the previous problem, the simplifying assumption that 289C and 1.10 atm would offset each other, so I'll do that, too.) 0.044 grams/10 ml = x/22.4 liters 0.044g/0.010 liters = x/22.4 liters 22.4 liters/0.010 liters = 2240 (ratio) 2240 x .044 = 98.56 (actual atomic weight) CCl = 35.5+12 or 47.5, so two of those is 95 grams/mole. This is sufficiient to distinguish C2CL2, (dichloroacetylene) from C6CL6 (hexachlorobenzene) which would mass 3 times as much.</span>
