The electron arrangement of the outer energy level of an atom determines whether or not it will form chemical bonds. Or The shared electrons are typically near the middle of the bond between the 2 atoms, in a covalent bond.
Answer:
4.4 g
Explanation:
The equation of the reaction is;
NaHCO3 (aq) + CH3COOH (aq) ----> CO2 (g) + H2O (l) + CH3COONa (aq)
Mass of baking soda - 4.5 g
Molar mass of NaHCO3 = 84.007 g/mol
Number of moles of baking soda= 4.5 g/84.007 g/mol = 0.0536 moles
If 1 mole of NaHCO3 yields 1 mole of CH3COONa
0.0536 moles of NaHCO3 also yields 0.0536 moles moles of CH3COONa
Hence;
Theoretical yield of CH3COONa = 0.0536 moles * 82.0343 g/mol = 4.4 g
Geothermal energy is the thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. The geothermal energy of the Earth's crust originates from the original formation of the planet and from radioactive decay of materials
The solution of Ba(OH)2 will have the lowest freezing point. This is because it dissociates into 3 ions, one Ba and 2 OH, which is more than any of the others. Freezing point depression is a colligitive property of water that depends, in part, on the number of ions.
hope it helps
