INVESTIGATION #2 DETERMINATION OF THE WATER OF CRYSTALLISATION April 4‚ 2012 OBJECTIVE: Chemical compounds that contain discrete water molecules as part of their crystalline structure are called hydrates. Hydrates occur quite commonly among chemical substances‚ especially among ionic substances. More often than not‚ such compounds are either prepared in‚ or are recrystallized from‚ aqueous solutions. Hydrates exist for ionic compounds most commonly‚ but hydrates of polar and non polar covalent molecules

State the principle of triple beam balance A beam balance measures mass as opposed to weight‚ so the mass you weigh will be the same on the moon as it is on earth. Gravity is taken out of the equation‚ unlike a spring balance that measures weight and would measure an article to be 1/6 of the weight on the moon as it would be on earth using the same spring balance that relied on gravity. The principle is that of moment‚ or turning force/torque)‚ calculated by force x distance. Fundamentally‚

Problem-posing education allows people to develop their human natures fully because it depends on dialogue‚ recognizes

The whiskey on your breath Could make a small boy dizzy; But I hung on like death: Such waltzing was not easy. We romped until the pans Slid from the kitchen shelf; My mother ’s countenance Could not unfrown itself. The hand that held my wrist Was battered on one knuckle; At every step you missed My right ear scraped a buckle. You beat time on my head With a palm caked hard by dirt‚ Then waltzed me off to bed Still clinging to your shirt The poem‚ "My Papa ’s Waltz"
