The general quadratic equation is ax^2+bx+c=0, now we need to Complete The Square, which allows us to have only one "x" term. First, divide the equation by "a", leaving us with x^2... ...

Effervescence and the magnesium metal would dissolve. Mg + 2HCl --> MgCl2 + H2

In terms of similarities, both processes involve generating a proton electrochemical gradient across a membrane, by pumping protons from an area of lower concentration to a higher concentration. This crea...

Before you start it is best to gather as much information as you can about the function. The most important things to find are any roots - as these will tell where the graph should cross the axis - and th...

F=ma, so a=F/m giving a=2.4m/s^2. When t=9s, v=at, so v=21.6m/s. Friction force is Ff = μF(normal), which is Ff = μmg, so Ff = 6670.8N (if g = 9.81m/s^2). Frictional force always acts against the directio...
