The first test conducted on unknown bacteria 32 was the Gram stain. From this stain‚ unknown 32 was found to be a Gram-positive cocci. This test eliminated all possible Gram-negative bacteria‚ Gram-positive rods and Gram-positive spirillium. Next‚ the endospore test determined whether or not the Gram-positive bacteria contained endospores. With the use of malachite green‚ steam‚ and safranin it was found that unknown bacteria 32 did not contain endospores. This eliminated Gram-positive cocci Sporosarcina

Conclusion: (Identity‚ % error‚ other evidence‚ how to improve) The identity of Unknown A is the compound cobalt(II) chloride hexahydrate (CoCl₂•6H₂O).This is justified by the similarities in color of red-purple crystal like grains‚ which is significant in identifying the product out of the eight suggested identities. Only two had similar characteristics which were CoCl₂•6H₂O and CoSO₄•6H₂O. Before unknown A was heated‚ there was a notable common physical property of the substance being red crystal

OUTLINE 1. Intro- Chemical and biological weapons first appeared in a large quantity in the First World War. Chemical weapons‚ such as sarin‚ nerve gas‚ and mustard gas‚ have to be made in a laboratory. Biological weapons‚ such as Typhus‚ Q fever‚ and Anthrax‚ can be viruses or bacteria. Chemical and Biological weapons have few advantages and so many disadvantages that the advantages aren’t worth the possible effects. 2. Paragraph 1-advantages that can be turned into disadvantages a.

WATERY WORLD Water Usage in HICs Agriculture (39%) – use water to irrigate crops‚ using automated machines that use lots of water. Industry (47%) – Water is used in production and for cooling. Some use 1million litres a day Domestic (14%) – piped water supplies used for baths (150L) and washing machines (100L) other Water Usage in LICs Agriculture (91%) – Less efficient and require man power. Water is wasted in evaporation. Industry (5%) – There is less industry‚ more small cottage shops
