Homework: Finish Chemthinks (2) and the Metals,Nonmentals, and Metalloid Lab due friday

-Take notes for the Chemthinks

Body:

Mr. Paek introduced a new lab in class about becoming familiar with chemical and physical properties of metals, nonmentals, and metalloids.

Here are the results from the lab if you missed it

Part one:

Sample A- silver, shiny, metalic, and round.

Sample B- Black, clusters, small, ashy

Sample C- Tiny, shiny, glittery, dark gray

Sample D- Pebbles, metalic, silver, mini

Sample E- Dust, yellow, powder-like

Sample F- silver, tiny

Sample G-gray,dusty,chalk-like

Part two:

Sample A-malleable

Samble B-brittle

Sample C-malleable

Sample D-malleable

Sample E-brittle

Sample F-Malleable

Sample G- malleable

Part three:

Sample A-conductor

Sample B-non conductor

Sample C-conductor

Sample D-conductor

Sample E-non conductor

Sample F-non conductor

Sample G-non conductor

Part Four: (Do HCL only)

Sample A- stays the same, no reaction

Sample B- Stays the same, no reaction

Sample C-bubbles and fizzes, water changes color, reaction

Sample D- No reaction

Sample E- no reaction

Sample F-bubbles, reaction

Sample G-bubbles, reaction

Part Five- (skip densities and do CuCl2 only)

sample a-turns black, melts and bubbles, reaction

sample b- bubbles, reaction

sample c-turned black, reaction

sample d- no reaction

sample e-no reaction

sample f- color changes to green and is warm, reaction

sample g-color changes to brown, reaction

Finish the postlab questions by looking at the element info/properties :)
