Are cations like sodium ion or copper ion electron deficient species or lewis acids
Because both of them have orbitals to accommodate electrons

I have a can of diethylene glycol that will burn complete in 6 hours. How much air (with 21% O2) will be required to burn all of the 7.41 fl. ounces of fuel?
Consider an atom that has an electron in an excited state. The electron falls to a lower energy level. What effect does that have on the electron?
How much water must be vaporized from 0.4 molar 200mL H2SO4 solution to make it 1.6 molar at same temperature?
Draw a labelled diagram depicting variation of radial probability density R-r) against (rlan) for an electron in 2s orbital
If Kinetic Energy is directly proportional to mass, than the gas with the larger mass would have the larger kinetic energy, right? But what if the two separate gases are in two non-rigid containers of equal volume (1 Liter), and at the same temperature (25 celsius). The two gases are Carbon monoxide and carbon dioxide. There are 2 atm of carbon monoxide, and 1 atm of carbon dioxide. I used PV=nRT to find the moles of CO and CO2 using these conditions and concluded that there is more of Carbon monoxide than there is Carbon dioxide. Shouldn't this mean that it has more kinetic energy than carbon dioxide? Still, I also know that temperature is indicative of average kinetic energy, and so if they are both the same temperature than they should have the same kinetic energy. So I guess I was confused about which was right.
A 0.004 mol dm-3 solution of epsom salts contains 1.072g of the salt on 1dm3 of solution. Find the mass of 1 mol of epsom salts. If the formula of epsom salt is represented by MSO4•7H2O, find the relative atomic mass of M.
40 cm3 of a solution of hydrated barium chloride , BaCl•xH2O, contain 1.952g of salt.
A) what is the mass concentration of the solution?
B) given that the concentration of the solution is 0.2 mol dm-3, find the value of x in the formula?
10cm3 of a solution of hydrochloric acid 6.125g H2SO4 How many moles of H2SO4 are present in 25.0cm3 and what is the concentration of this solution in mol dm-3?
