CEM 141 MSU Exam 2 Questions and Answers Already Passed Which reaction requires the most energy? A. N(g) → N+(g) + e - B. N+(g) → N2+(g) + e - C. F(g) → F+(g) + e - D. F+(g) → F2+(g) + e - D. F+(g) → F2+(g) + e - Fluorine has a higher effective nuclear charge than Nitrogen - so it is harder to remove an electron (takes more energy because the electron is more strongly attracted by the nucleus). Effective nuclear charge is the same for F and F+ because the number of pro...

Lights acts as what? - Answer-Particle and wave. Wavelength - Answer-The distance (m) of waves from peak to peak. Short: x-ray (red), long: infrared (blue) Short - higher energy Long - lower energy Frequency (V) - Answer-The number of wavefronts per second. Highest: x-ray Velocity of Light - Answer-C = 3.00 X 10^8 = wavelength X frequency Amplitude - Answer-The intensity, height of peaks of waves. Highest: blue light Energy of Wave (J) - Answer-Increases as frequency increases and as wa...

Acceleration - Any change in speed or direction Activation energy - the amount of energy needed to start a reaction All objects experience the same acceleration due to - gravity, but only in the absence of air friction Alloys - mixture of metals Alpha decay - a nucleus gives up a helium nucleus Amplitude - The height of the wave, how far you are from the equilibrium Angular Momentum conserved - Angular momentum = Mass * Velocity * Radius Ice Skater ex. As she pulls her arms in, velocity i...

Atom definition The smallest component of an element Compound Two or more elements, chemically joined in fixed proportions. They can only be separated by chemical means. Mixture Two or more elements/compounds which are not chemically combined. Ways to separate mixtures - Filtration - Evaporation - Crystallisation - Simple distillation - Fractional distillation - Paper chromatography The plum and pudding model Before electrons were discovered, people thought that atoms were indivi...

General Chemistry 1 Exam 1 | Latest Update | 2024/2025 | Rated A+ What is the role of the Pauli exclusion principle in determining the electron configuration of atoms? The Pauli exclusion principle states that no two electrons in an atom can have the same set of quantum numbers, which helps determine the unique electron configuration and arrangement in orbitals. How do isotopes of the same element differ from each other? Isotopes of the same element have the same number of proton...
