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

Arefrigerator uses r-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 34 percent and leaves the compressor at 70Β°c. if the compressor consumes 450 w of power, determine (a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator. (0.00644 kg/s, 800 kpa, 2.03)
