Angela was instructed on a test to make an analogy or comparison for palmers she writes for examples of how palmers are like pearl necklaces she has many parts to this analogy that makes sense but one part of her analogy does not fit which is the most likely air in her analogy a the pearls are like monomers b the thread that connects the pearls is like an ionic bond see the entire necklace is like a polymer or macromolecule or be stringing the beads onto the thread is like polymerization

we need the questions , i may then you.

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.      

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
