ALEKS Modules 1-7 (2022/2023) Rated A

ALEKS Modules 1-7 (2022/2023) Rated A Fahrenheit Equation Tf=(Tc x 9℉/5℃) + 32℉ Celsius Equation Tc= 5℃/9℉ (Tf - 32℉) More Equations Ep=h x v c=weird symbol x v Average Velocity of a Gas Particle Vrms = square root (3RT/MM) R= gas law constant T= temperature MM= molar mass of gas particles Base for log It is 10 10^5 log10(100,000)=5 Base for ln e Euler's number Rules for Counting Significant Figures 1. Any non-zero digit in a measurement is significant (11325 has 5 sig figs) 2. Zeros between non-zero digits are considered significant (4003 has 4 sig figs) 3. Zeros to the left of the first non-zero digit are insignificant (0.072 has 2 sig figs) 4. Zeros to the right of the non-zero digits are significant only when the number contains a decimal point (400.0g has 3 sig figs whereas 400g only has 1 sig fig) Form of Scientific Notation N x 10^M N is a number between 1.000 and 9.999 Ex: 400 = 4.0 x 10^2 Rules for Using Significant Figures Multiplication/Division: must have same number of sig figs as lowest number Addition/Subtraction: last common place rule Logarithms: numbers after decimal are significant. Round answer to whole SI Prefixes Factor = Prefix 10^12 = tera (T) 10^9 = giga (G) 10^6 = mega (M) 10^3 = kilo (K) 10^-2 = centi (c) 10^-3 = milli (m) 10^-6 = micro (μ) 10^-9 = nano (n) 10^-12 = pico (p) 10^-15
