Estimating exactly how long treated lumber will take to dry is hard to predict, and will depend on the time elapsed since pressure treatment, sun exposure, local temperature and recent weather conditions. Take these factors into consideration for your specific installation and use your best judgment.
sugar is a covalent bond made up of 12 atoms of carbon, 22 atoms of hydrogen and 11 atoms of oxygen. (C12H22O11) it is covalent because it is made up of bonds between non-meta â¦ ls.

Best Answer: The general (and I mean general as there are some exceptions) rule for determining if a compound is ionic or covalent is by looking at what types of atoms are bonding: If you look at Al2O3 (aluminum oxide) you have a metal bonding with a non-metal.luminium oxide Al2O3 is ionic because of the presence of the metal ion, Al3+ and non-metal ion O2-. Methane CH4 is covalent as all the elements in it are non-metals. It has carbon and hydrogen, both of them are non-metals.
