solubility is a measure of How easily something will dissolve in a solvent What does solubility depend on Strength of the attractions within the substance being dissolved and between the solute and solvent Solubility increases with temperature True or False True What is the only non- metal that is a good conductor Graphite What allows transition metals to be catalysts More than one ion/variable oxidation states Group 1 metal plus water Metal hydroxide plus hydrogen Fluorine properties A v...

nucleus middle of the atom, contains protons and neutrons, positive charge protons positively charges neutrons no charge electrons negative charge number of protons equals number of electrons atoms of an element have the same number of protons one proton in nucleus hydrogen two protons in nucleus helium horizontal rows periods vertical colups groups elements in the same groupo similar properties group same number of electrons in their outer shell group 18 noble gases - eight electron...

Reactivity series of metals an order of reactivity, giving the most reactive metal first, based on results from a range of experiments involving metals reacting with oxygen, water, dilute hydrochloric acid and metal salt solutions Extraction of metals Most reactive metals are extracted from their ores by electrolysis of a molten compound. Iron ore blast furnace Fe2O3 + 3CO → 2Fe + 3CO2 - Carbon is higher in the reactivity series than iron and is therefore able to remove the oxygen from iron(...

What does a Nuclues contain? Genetic material that controls the activities of the cell What is cytoplasm and what does it contain? Gel like substance where most chemical reactions happen; contains ezymes What are mitochondria? Site of aerobic respiration and releases energy that cells need to work What does the cell membrane do? Holds the cell together and controls what goes in and out What extra features does a plant cell have compared to an animal cell? Cell wall, chloroplast, vacuole Wha...

What is the main 4 processes that happen when in cell division? Cells get bigger. The cell duplicates the DNA. The cell prepares to divide. The cell divides by mitosis. What is interphase? When the cell grows and duplicates the DNA. This will happen regardless what How many pairs of chromosomes do humans have? What do somatic cells have? 23 pairs of chromosomes and we usually call them 2n worth of genetic material. What is mitosis? Mitosis involves the replication of genetic material which me...

Which events will occur when outside is too hot and the individual is sweating a lot? -Water content in blood is low -ADH production increases -Effect on nephrons on kidney high water absorption -Urine concentration concentrated How can sexually transmitted diseases be speead Through blood transfusion, skin contact (herpes) and pregnancy/child birth Sharing food or beverages does not transmit sexually transmitted diseases - similarly to respiratory droplet spread, these pathogens need to come i...

Anaerobic respiration leads to an O2 debt Which type of resp leads to O2 debt? Anaerobic Aerobic respiration Releases more energy per unit glucose than anaerobic Decrease aerobic resp --- decrease energy available for active transport Which type of resp releases more energy per unit of glucose? Aerobic Total amount of respiration in cell given by amount of CO2 produced (from aerobic respiration) + amount of lactic acid produced (from anaerobic respiration) Ribosome site of protein synthesis...
