Practice writing the compounds different ions will make when they react. I will give you 2 ions that will react. You need to write the correct formula for the compound that those two ions will create.
For example:
When potassium reacts with sulfur
first write the ions for each element
K1+ and S2-
Then write your basic compound formula. Put the positive ion first, then the negative ion
KS
Then use the charge number to determine how many of each atom is required to make a neutral compound like we did in the nearpod video (remember you don't need to write 1s in your formulas)
K2S This formula is complete!
Write the formulas for the following reactions:
When calcium reacts with oxygen
when lithium reacts with sulfur
when caesium reacts with phosphorus
when strontium reacts with iodine

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.
