Chemical reactions and quantities Flashcards
chemical reactions
involves the change of the bonding between atoms in the reactants in forming the products
chemical change
occurs when a substrate is converted into one or more substances with different formulas and different properties
signs that a chemical reaction is taking place
formation of bubbles
change in color
production of a solid
heat is produced/absorbed
heterogenous situation
different states
combination reaction
2 or more elements form one product
decomposition reaction
one substance splits into 2 or more simpler products
single replacement reaction
one element takes the place of a different element in another reacting compound
double replacement reaction
the positive ions in the reactant compounds switch places
combustion reaction
a carbon-containing compound burns in oxygen gas to form carbon dioxide and water. energy is released as a product in the form of heat
toxicity of CO
- carbon monoxide is a colorless, odorless, poisonous gas
- attaches to hemoglobin molecules when inhaled
- reduces the amount of oxygen that can reach the cells
- causes a person to experience a reduction in exercise capability, visual perception and manual dexterity
hemoglobin
protein in the blood that transports oxygen to cells
what happens when hemoglobin bound to CO reaches 10%?
a person may experience shortness of breath, mild headache, and drowsiness
what happens when hemoglobin bound to CO reaches 30%?
a person may experience more severe symptoms, including dizziness, mental confusion, severe headaches, and nausea
what happens when hemoglobin bound to CO reaches 50%?
a person could become unconscious and die if not treated immediately with oxygen
redox of FAD
FAD can be reduced to FADH2 by the transfer of 2 hydrogen atoms: necessary for the production of energy
