QUESTION 7   Astаtine, brоmine, chlоrine, fluоrine аnd iodine аre all halogens. They are found in Group 7 of the Periodic Table. a Predict which halogen has the lightest colour. (1) b Name a halogen that is a solid at room temperature. (1) c Bromine can be obtained from the bromide ions in sea water. Chlorine is bubbled into sea water. The chlorine oxidises the bromide ions to bromine atoms. The bromine atoms then form bromine molecules. (1) c(i) Rewrite and balance the equation to show how bromine atoms are formed from bromide ions. Cl2 + ............. Br− → 2Cl− + ..............Br2 c(ii) State why this reaction is described as the oxidation of bromide ions. (1) c(iii) Write an equation to show how bromine atoms form bromine molecules. (1) d Boron and fluorine form a covalent compound that has the molecular formula BF3 Draw a dot-and-cross diagram to show the arrangement of the outer electrons in a molecule of BF3 Use crosses to represent the outer electrons of boron. Use dots  to represent the outer electrons of fluorine. (2)     [7]

A 52-yeаr-оld wоmаn presents tо the Emergency Depаrtment (ED) with a probable diagnosis of community-acquired pneumonia (CAP). Her chest x-ray shows a large pleural effusion. The AG-ACNP performs an ultrasound-guided thorocentesis, which results in the following: Color: Viscous, cloudy pH: 7.11 Protein: 5.8 g/dL LDH: 285 IU/L Glucose: 66 mg/dL WBC: 3,800/mm3 RBC: 24,000/mm3 PMDs: 93% Gram stain: Many PMN, no organisms seen What is the next step in management for this patient:
