Reactions of metals with salt Metal + Acid = Salt + Hydrogen 1 of 27 Hydrochloric acid as a salt Chloride 2 of 27 Nitric acid as a salt Nitrate 3 of 27 Sulphuric acid as a salt sulphate 4 of 27 Word equation for. The reaction of metal and water Metal + Water = Metal hydroxide + Hydrogen eg. magnesium+water=magnesium hydroxide+hydrogen 5 of 27 Word equation for. Reaction of Metal oxides with acid metal oxide + acid = salt + Water. eg. Copper oxide+Nitric acid=copper nitrate+Water 6 of 27 word equation for. Reactions of metal carbonates with acid Metal Carbonate + Acid = salt + Water + Carbon dioxide eg. Calcium carbonate+nitric acid+calcium nitrate+water+carbon dioxide 7 of 27 Thymine pairs with adenine 8 of 27 Cytosine pairs with Guanine 9 of 27 What is the backbone of a gene made out of Phospate and deoxyribose (sugar) 10 of 27 What contains DNA Every nucleus apart from those in a red blood cell 11 of 27 Continuous variation A series of characteristics that can take any range. eg. Human height or handspan 12 of 27 discontinuous variation When a series of characteristics have set values. eg. human blood groups where there are 4 set groups and no other possibilities 13 of 27 what is an ecosystem a biological community of different animals and plants 14 of 27 what is biodiversity a range of different species in an ecosystem 15 of 27 What does sound travel in longitudinal waves 16 of 27 what does light travel in transverse 17 of 27 What is frequency on a wavelength how many waves there are 18 of 27 what is amplitude on a wavelength loud or quite (How high or low the peaks are) 19 of 27 What is an echo an echo is when sound energy bounces of something into your ear 20 of 27 What does the choclea do convert sound into electrical impulses 21 of 27 what does the auditory nerve do allow the electric impulses to travell into the brain 22 of 27 Colours in the spectrum Richard of york gave battle in vein: red, orange, yellow, green, blue, indigo, violet 23 of 27 Why do the colours split in the prisim Because they travell at different speds 24 of 27 Red and green make yellow 25 of 27 green and blue make cyan 26 of 27 red and blue make magenta 27 of 27
