Ionic Bonding Practice
For this assignment you need to 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

On a day when the barometer reads 75.23 cm, a reaction vessel holds 250 ml of ideal gas at 20 celsius. an oil manometer ( ρ= 810 kg/m^3) reads the pressure in the vessel to be 41 cm of oil and below atmospheric pressure. what volume will the gas occupy under s.t.p.?

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
