Monatomic Ions and Their Charges show me a perfect score
Write a lewis dot structures for these substances: calcium floride, Vanadium (II) sulfide, copper(I)oxide, I2, SiCl4, PI3, BaI2, H2O, PO4-3 ,NH4+1 then make another structure using dashes.... (ionic compounds don't share electrons, so don't do this with them)
Are all of these covalent compounds?
If it is a molecule, tell what shape it is and whether it is polar or non polar; if it is a polyatomic ion, describe its shape, but not polarity; if it is an ionic compound only give dot structure.
What is VSEPR? What does it have to do with molecular shapes?
What is the general rule for determining what liquids will mix? Give examples.
draw 2 or more water molecules, and label covalent bonds and hydrogen bonds. Which is stronger?
What would these atoms do to become stable, & what would be their resulting ionic charge?
K, Rb, Xe, P, B, Sr, Cr (I)
What is charge of iron(II) ion? iron(III)?
Write the formulas for these compounds. What type of bonds are found in them? iron(II) oxide, iron(III) oxide, Sodium sulfide, Strontium chloride, Carbon dioxide, aluminum bromide, aluminum sulfide, calcium phoshide, dinitrogen trioxide, cesium Iodide, carbon monoxide,
Cobalt (III) bromide, Titanium (III) oxide, Sodium sulfate, calcium nitrite, aluminum phosphate , strontium phosphate
Explain the paper chromatography experiment(if we have done it), using the word polarity. Be sure to review the lab and the demonstrations on polarity.
explain what is going on with bending water from the buret and marble demo.
explain how to calculate Ratio blue (rb) from chromatography data
explain and describe reasons for some special properties of water.
