Why is the Nucleus' charge postive?

The Nucleus' charge is positive b/c it contains Protons with a positive charge and Neutrons with no charge.

100

Is this a Type I or Type II Binary Ionic Compound (BIC)? 

"Calcium Hydroxide"

Type I b/c Calcium is a Main Group Element (A Gp).

100

Write the fractions you would need to complete this calculation. Calculate the #mol H2 needed if 66.9 g O2 are used.

BCE=2H2(g)+ O2(g) ----> 2H20(g)

MM(H2)=2.02 g/mok, MM(O2)=32.00 g/mol

Fraction #1: (66.9 g O2 / 1)

Fraction #2: (1 mol O2 / 32.00 g O2)

Fraction #3: (2 mol H2 / 1 mol O2)

200

What is the equation to find the pH of a solution?

pH=-log[H+]

300

Explain trend for Atomic Radius (AR) going down a Group and why.

AR increases going down a Group because Valence Electrons (VE) occupy higher Principal Energy Levels (PEL), which extend further away from Nucleus.

300

Name the compound.

Si3N6

 Trislilicon Hexanitride

300

Will this Reaction occur?

MgCl2 + 2Sn ---> 2SnCl+ Mg

 NR

300

Why is calculating the limiting reactant important?

 Calculating the limiting Reactant allows us to calculate the exact amount of Product produced.

300

What is the equation to find the pOH of a solution?

pOH=-log[OH-]

400

Describe the Trend in Ionization Energy (IE) as you move down a Group and why.

   IE decreases as you move down a Group b/c VE are further away from the Nucleus due to increased Atomic Radius, making VE removal easier. 

400

Which chemical Bond type do Type III Binary Compounds consist of?

Covalent Bonds

400
