My landlord pays the energy, but I put a big wardrobe-like thing in front of the window.
Good job! Although you say you are not an environmentalist, your long-term thinking about payback in a few years is similarMany people are short-sighted, and would see insulation and efficiency as unnecessary expensesWe have insulation and CFL's, but not those other measuresBut then again, we don't have A/C, anyway, so there's no cold air to keep inAnd we have a solar array, so our net electricity usage is negative at this time of year.
25a) n4; l n-1; therefore s, p,d, and f orbitals 32 electrons b) 4f orbitals 14 c) 18 26a) magnesium (Mg) b) Aluminum (Al) c) Chromium (Cr) 27a) Excited b) Ground C) Excited d) Excited (unless you inadvertently left out the 4f orbitals) Ground state would be: [Xe]6s^2 4f^14 5d^10 6p^3
