Solving Proportions, Using Exponents

Solving Proportions, Using Exponents. Proportions. Many chemistry problems deal with changing one variable and measuring the effect on another variable. We call these proportions (fractions) when there is a direct relationship between the two variables.

  2. Proportions Many chemistry problems deal with changingone variable and measuringthe effect on another variable. We call these proportions(fractions) when there is a direct relationship between the two variables. When you recognize a problem as a proportion, you can easily solve it by cross-multiplying to isolate the unknown variable.

  7. Exponents Understanding and using exponents and logarithms will be essential in chemistry. positive powers: 33 = 3*3*3 negative powers: 3-3 = negative bases: -33 = -3*-3*-3 fractional bases: 3 = **

  8. Exponents Understanding and using exponents and logarithms will be essential in chemistry. powers of 1: 31 = 3 powers of 0: 30 = 1 radicals: = 31/3 mixed radicals: = 32/3

  9. Exponents Understanding and using exponents and logarithms will be essential in chemistry. multiplying common bases: 33*32 = 33+2 dividing common bases: 33÷32= 33–2 base 10 logarithms: log10(100) = 2 102 = 100 natural logarithms: loge(148.4) = 5 e5= 148.4

  10. Logarithms Calculate log(71)
