Chemistry

Gabbie Emily 9/9/12 visible and chemical substance substance Properties think: The plan of this experiment is to develop the visible and chemical properties of the confused substances. surgical process: First, we examined the substances and wrote piling their various properties. Then we smelled the substances. undermentioned we looked at the substances in weewee. Finally, we check over to see if drawing tease had any effect on them. info: Physical Properties Table warmness Formula | Physical declare| twist| Odor| solvability in Water| kernel of drawing card| due south S| Solid pulverise| Yellow| gooey orchis| No| No| cast-iron Fillings Fe| grunge care| Gray| No| No| Yes| Sodium hydrogen veer NaHCO3| Like sugar| bloodless| Yes| Yes| No| Sodium Chloride NaCl| mettlesome | flannel| No| Yes| No| Sucrose C12H22O11| Grainy | White| No| Yes| No| magnesium Mg| Long, thin| silver medal medal| No| No| No| Sand SiO2| arenaceous| topaz| No| No| No| | | | | | | Physical or Chemical Changes System| placard| Fe and S assortment -tested with magnet| Gray/ xanthous powder Iron apart(p) from entropy| NaCl and Sand-Mixed with water-Filtered-Filterate allowed| NaCl dissolved, wet sand, a critical salt in the water | Mg: burned in air| Very bright, ashes nuclear number 18 discolour| Mg with 10M HCl| Its refrigerated.

| Combustion with mathematical product HCl| They were both warming; the teddy boiled.| C12H22O11 heated | It stird state and people of colour; smelled like marshmallows. | NaHCO3 with HCl| It was cold| info Analysis: 1. The various substances had precise different chemical and somatic properties. Conclusion: Physical and chemical properties for several substances were observed. some(prenominal) changes were identified as physical or chemical changes. threesome of the reactions were appoint to be physical and four were found to be chemical. Iron sundry(a) with Sulfur was a physical change because the substances did not change when combined together. Iron could be separated using physical...If you deprivation to get a abounding essay, golf-club it on our website: Orderessay
