It seems to have choices. You can get the electronegativity order from the periodic table of elements. From left to right, the electronegativity will also increase. From top to bottom, it will decrease.
Hello,
You balanced the equation and then you have to set up what is called a psychometric equation for each reactant so that you get the same unit for each in order to compare the two. so for (calcium hydroxide) = 78.5 g ÷ (40.1 + 32 + 2) = 1.0593 mol * Note: I just broke it down in my own science way..u can just get the molar mass of calcium hydroxide which is approx 74 g/mol
Hope this helps
The Ankeny Substance Abuse Project (ASAP) is a nonprofit alliance of Ankeny area volunteers representing businesses, churches, civic groups, families, public agencies and other organizations dedicated to fostering a safe community free from illicit drugs and alcohol abuse.
Hope this helps.
There doesn't seem to be a clear answer, it is placed in the center when it's substances is on the corners it doesn't give anything else
The equivalency point is at the point of the titration where the amount of titrant added neutralize the solution. When it’s a strong acid strong base titration, the equivalence point will be 7. When it is a weak acid strong base, the equivalence point it more basic (the exact number depends on what acid and base you use). And when it is a strong acid weak base, the equivalence number is more acid (the exact number depends on what acid and base you use). Hope this helps!
