Thus I assumed an asymptote at 23°C. 1st equation: An equation for an exponentially decaying graph is in the form of: y = a + b (e –m x) Where: a= Vertical Translations (Ambient Temperature)‚ b= Dilations‚ m= Gradient x= Time (t)‚ y= Temperature (T (t)) From the data‚ we know that the value of ‘a’ is always equal to 23 °C. The original equation is equal to: T (t) = 23 + b (e –m t) This part of the investigation had some issues. I had formed the equation but was confused on how to solve it. Later

combusts as: CH4(g) + O2(g) ---> CO2(g) + 2 H2O(g) Net Ionic Equations Net ionic equations are equations that show only the soluble‚ strong electrolytes reacting (these are represented as ions) and omit the spectator ions‚ which go through the reaction unchanged. When you encounter net ionic equations on the test‚ you’ll need to remember the following solubility rules‚ so memorize them! Also keep in mind that net ionic equations‚ which are the bare bones of the chemical reaction‚ usually take

is ‚ and its purpose is to solve quadratic equations and can only be applied to a quadratic equation that is in the standard form of (ax2+ bx +c = 0).It is important to differentiate between a quadratic formula and a quadratic equation‚ where the quadratic formula is a tool‚ and the quadratic equation is specifically given to you for the purpose of solving it. When solving a quadratic equation‚ you are basically finding the roots of that specific equation. Those roots will tell you where the line

certain run from the previous task was twice duplicated to for a “hot and cold” test for reaction rate. The prior run was again duplicated for a test with catalyst. The data obtained was graphed in a linear regression form‚ using the Arrhenius equation: lnk=-EaR-1T+lnA‚ reaction rate: rate = k[A]x[B]y and other principles held in chemistry. The graph from the results determined that there is a relation between rate and the previously mentioned factors. The results validated the notion that temperature

the left side of the problem of our equation 25x = 0 or x-12 = 0 this is called the Zero Factor Property we are using X = 0 or x = 12 parabola will cross over the x-axis at 0 and 12. I have solved for x. Now we will find the axis symmetry the x = - b/2a. We determine here if the Parabola has a maximum or a minimum value. At this point we will now solve the equation by breaking down the a = -25‚ b = 300
