Matter consists of atoms. All matter can be classified as being either a pure substance or a mixture. Matter can exist as either a solid, liquid, or a gas and can change among these three states of matter.
Mixtures can be heterogeneous made up of two or more physically different parts or states of matter or homogeneous consisting of components that cannot be individually detected. Homogenous mixtures are usually called solutions. In a two-component system, the major component is called the solvent and the minor component is called the solute.
Aqueous solutions have water as the solvent. If the components of a solution can be mixed in any proportion, they are said to be miscible. A colloid is a mixture in which the particles of the lesser phase are intermediate in size between those present in the homogeneous mixtures and those in heterogeneous mixtures; typically they are on the order of 10 to 10, angstroms in diameter.

Mysteries of matter, therefore, have a fascination for thoughtful laymen as well as scientists and technologists. The atom has long been familiar as the ultimate unit of matter". Lord Ernest Rutherford - Learn about each elements physical characteristics and atomic structure by periodic chart of elements and each elements associated physical characteristics.
At first concentrate on the more common elements of hydrogen, oxygen, carbon, sodium, potassium, sulfur, and a few metals like copper, zinc, silver, mercury, and lead. Later you can study the rest of the elements. Web Elements Online - http: Pictorial Periodic Chart http: Periodic Chart and other interesting things. The periodic table, www.

In a study of magnesium absorption, chemist Joseph Domek measures magnesium content in water with an atomic absorption spectrophotometer. Photo by Scott Bauer.
Study chemical reactions by reading sections on stoichiometry in chemistry text books and demonstrating them with laboratory experiments. See laboratory cautions below. Combining elements to form new combinations is a very important part of chemistry.
Also look up the words in your dictionary for additional understanding. Learn about the concept of a MOLE. Learn more about chemical reactions HERE. Our last stage is to put in state symbols, s, l, g, aq , as appropriate. On a molar basis, we can say that one mole of iron 56g reacts with one mole of sulfur 32g to produce one mole of the compound iron II sulfide 88g.
You will need the ability in chemistry to describe formulas for any substance you come across. Oxygen O has a charge of Carbon C has a charge of When by knowing the number of charges each ion has.
For example syou see these elements in a formula; substitute the charge numbers and that will tell you how many atoms of each element are needed to balance the equation. When we say one, it could mean one atom or one mole. This is sodium chloride or common table salt. What about aluminum and chlorine? Some elements can have various charges like iron.
Construct a Lewis Structure Tutorials-1 Sites to help students practice skills needed for the Chemistry exam How do I draw a Lewis structure for a molecule? Names of common acids and their salts follow these simple rules: Acids Bases and Alkaline Materials Salts. Alkali Metals Precious Metals Chemistry:: Metric Measurement for Chemistry. Measurements metric unit General Chemistry Online: Measurement [PDF] Chapter 1: Chemistry and Measurement What is.
You are guaranteeing that your X-axis values will be plotted only, at frequency of 4 " generic x-axis" values:. Setting this to vale to 1 will give a value for every x-axis value, that is incremented as a whole number in this case days. Each data point in a series has X and Y values that determine its position in the plotting area.
With some charts, the X value of points is not important, and does not have to be provided. In this case, the point positions in the plotting area are determined only by their point index i. When X values are "indexed", the data point index, not a point's X value, is used to determine the position of points along the categorical X axis. For example in Figure 1 below, two charts are shown displaying the same data.
However, the first chart uses non-indexed X values, therefore the X values of those points determine their location along the x-axis. The second chart is indexed, therefore its point indices are used to determine their position along the x-axis. In this case the X values are only used for the axis labels, and nothing more.
I sourced my original information regarding intervals and interval offsets at the following site:. For example, assume you wish to create a re-occurring StripLine to highlight weekends.
You set the interval to 7 and its type to Days. Since the first point is Sunday you set the IntervalOffset to 6 to mean the 6th day of the week and its type to Days. The resulting chart does not show the first StripLine.
A good rule of thumb to follow when using the Interval and IntervalOffset properties of the Chart is that the IntervalOffset should be a lower interval magnitude than the Interval ie. Florian, can you pls show the code for the labels, properties etc of the x-axis?
Did you ever consider 3rd party plotting components, such as ZedGraph? Most likely such little caveats are already covered there. Give it a shot! I think I have your solution, just need clarification, you have all the tools within vb. Actually, I could also write some sample text at the X axis values, the dates are only confusing. The main problem is that the VB chart somehow calculates a very big margin on those descriptions at the X axis.
It doesn't show that you have formatted your date and date string. There also needs to be taken into account, that you are not using the en-US date format I'm in Australia, so we have the same format as you. The default date type is for en-US. ToString IFormatProvider method returns the string representation of a date and time value using the short date and long time pattern of a specific culture.
The following example uses the DateTime. ToString IFormatProvider method to display the date and time using the short date and long time pattern for the fr-FR culture. Please see this link: I think you should convert the string date representation to an actual datetime object before adding it to the chart.
