LAB: PHYSICAL AND CHEMICAL CHANGES REPORT i wrote this cinscase anyone has 10th chemistry edge 2020 and has to do the lab report cause this was horrible hope i help someone this only the 1st part though u have to do the rest srry

INTRODUCTION
These experiments are to help understand the differences between physical and chemical change. It shows how to recognize each type of change when it occurs. In a physical change, one or more physical properties are altered. A chemical change involves the formation of one or more new substances. How do we classify physical properties and chemical properties?

HYPOTHESIS
If I observe a chemical change, then composition of a substance does change, because chemical change involves the formation of one of more new substances. If I observe a physical change, then composition of a substance doesn't change, because in a physical change the original properties will stay the same.

VARIABLES
Independent Variables : Calcium carbonate, Calcium carbonate and hydrochloric acid, Water, Copper sulfate pentahydrate, Iron filings and sulfur, Lead nitrate and potassium iodide, Magnesium and hydrochloric acid, Candle
Dependent Variables: hydrochloric acid, boiled water, result of copper sulfate pentahydrate being heated up, mixture of iron filings and sulfur, combination of lead nitrate and potassium iodide, magnesium strip, the melted candle
Controlled Variables: Motar and pestle, hot plate, Bunsen burner, magnet, thermometer, the lit match

MATERIALS
Calcium carbonate, Mortar and pestle, 3 spoons, Hydrochloric acid, 3-50ML beakers, 1-100ML beaker, Hot plate, Hot pad, Copper sulfate, Crucible, Crucible tongs, Clay triangle, Tripod, Bunsen burner, Iron filings, Sulfur, Petri dish, Magnet, Potassium Iodide, Lead nitrate, Graduated cylinder, Magnesium ribbon, Thermometer, Tweezers, Candle, Match
PROCEDURE
Gather materials for each step.
Calcium Carbonate: (Calcium chalk, mortar and pestle)
Place calcium carbonate chalk in a mortar. Crush the calcium carbonate with the pestle
Record all changes observed, type of change, and your reasoning in the data table.
Calcium carbonate and hydrochloric acid: (Crushed calcium carbonate, mortar and pestle, one spoon, hydrochloric acid, 50 mL beaker)
Take crushed calcium carbonate in the mortar and pestle, and scoop it out with a spoon, placing it in 1.0 ML Hydrochloric acid.
Record all changes observed, type of change, and your reasoning in the data table.
Water: (Hot plate, 100 mL beaker, Crucible tongs)
Place the beaker with water onto the Hot plate, using the Crucible tongs. Turn the Hot plate on, and watch the water boil.
Record all changes observed, type of change, and your reasoning in the data table.
Copper Sulfate Pentahydrate: (Tripod, Bunsen burner, copper sulfate, crucible, spoon)
Grab copper sulfate with a spoon, and place it into a crucible. Next place the crucible with copper sulfate onto a Tripod and put a Bunsen burner underneath it. Turn Bunsen burner on.
Record all changes observed, type of change, and your reasoning in the data table.
Iron filings and Sulfur: (Iron filings, Sulfur, 2 spoons, Petri dish, Magnet)
Take a scoop of Iron filings and sulfur using the 2 spoons and place it onto the Petri dish. Mix the Iron filings and sulfur together using a spoon. Place a magnet above the mixture.
Record all changes observed, type of change, and your reasoning in the data table.
Lead nitrate and potassium iodide: (0.1 M Potassium Iodide, 0.1 M Lead Nitrate, 50 mL Beaker, Graduated cylinder)
Pour the 0.1 M Lead Nitrate into the 0.1 M Potassium Iodide beaker using a Graduated cylinder.
Record all changes observed, type of change, and your reasoning in the data table.
Magnesium and hydrochloric acid: (1 M Hydrochloric acid, Thermometer, 50 mL Beaker, Tweezers, Magnesium ribbon)
Place a Thermometer into the 1 M Hydrochloric acid and record the temperature. Next using the tweezers pick up the Magnesium ribbon and place it into the 1 M Hydrochloric acid. Record the temperature using the Thermometer.
Record all changes observed, type of change, and your reasoning in the data table.
Wax Candle: (wax candle, A lit match, time)
Grab a lit match and light the wax candle. Wait some time and see what changes happen to the candle.
Record all changes observed, type of change, and your reasoning in the data table.
