An Arrhenius base that contains aluminum is Al(H2O)5OH2+ This ion has the unwieldy name pentaaquadihydroxoaluminum. An Arrhenius base that contains lithium is LiF. This compound is known as lithium fluoride and is basic because F- is the conjugate base of the weak acid HF, and thus will form hydroxide ions in solution.
According to the Arrhenius model, an acid is any substance that produces hydrogen ions (H+) in a water solution, and a base is any substance that produces hydroxide ions (OH-) in a water solution. For example: NaOH ------> Na+ + OH- In this equation, NaOH dissolves in water producing a sodium ion (Na+) and a hydroxide ion (OH-), and thus it is a base. CH2O2 ------> CHO2- + H+ H+ + H2O ------> H3O+ in these two reactions, formic acid (CH2O2) dissolves in water to produce a formate ion (CHO2-) and a hydrogen ion (H+), which immediately attaches to a water molecule to form a hydronium ion (H3O+), and thus is an acid.
An example:NaHCO3 + HCl = NaCl + H2O + CO2
A double replacement equation has two reactants, each composed of two species, and they exchange "partners" to form either a gas, a precipitate, or a liquid (H2O most often). If none of these happen, and all reactants and products are soluble, then NO REACTION takes place. Example:AB(aq) + CD(aq) ==> AD(s) + CB(aq)
being able to write a balanced equation for a reaction is very important. By balancing an equation we can tell how much material we will need to start with, what the likely products to form, and how much of these products will form
Point-slope form is just another way to express a linear equation. It uses two (any two points that fall on the line) and the slope of the line (Therefore the name point-slope form).y2 - y1 = m(x2 - x1)...with m as the slope.
There have been as many Swedish chemists as in other leading countries, but there are two names who stick out the most, historically. Alfred Nobel (not a pure chemist per say, but more of an inventer) and Svante Arrhenius. Svante Arrhenius is most known for the Arrhenius equation, an accomplishment, among others, for which he received the Nobel Prize.
You use point-slope form to find the equation of a line if you only have a point and a slope or if you are just given two point. Usually you will convert point-slope form to slope-intercept form to make it easier to use.
The equations are equivalent.
Substitute the values for the two variables in the second equation. If the resulting equation is true then the point satisfies the second equation and if not, it does not.
The "form" only refers to how the equation of the line is written. It has no effect on what the line looks like when the equation is graphed. To graph a linear equation, no matter what form it's written in: -- Pick a number for 'x'. Use the equation to calculate 'y'. Graph the point. -- Pick another 'x'. Use the equation to calculate the new 'y'. Graph the point. -- Draw a straight line between the two points, and as much farther as you want to in either or both directions.
The point where two lines form an angle is called the vertex.
The standard form of a linear equation is y = mx + bwhere m is the slop of the line, and b is the y intercept.If you have two points (x1,y1) and (x2,y2), you can get the slope with the following formula:m = (y2-y1)/(x2-x1)if you plug this number in to the equation you can then plug in any (x,y) point on the line to solve for b.
the vertex is the point where two rays begin and form and angle

To graph the set of all the solutions to an equation in two variables, means to draw a curve on a plane, such that each solution to the equation is a point on the curve, and each point on the curve is a solution to the equation. The simplest curve is a straight line.
The equation is (y - 1) = 2/3*(x - 5) That can be simplified to 3y - 3 = 2x - 10 or 3y = 2x - 7
