During time some corrosion can be observed.
Sorry bud, been looking for the same. Sorry for the Troll though
Iodine added directly to a leaf in an experiment can be used to test for the presence of starch. If the leaf turns blue-black, it indicates that starch is present in the leaf, as iodine reacts with starch molecules to produce this color change. This is commonly used in biology experiments to show the photosynthesis process in plants.
When antifreeze is added to water, it lowers the freezing point and raises the boiling point of the mixture. This helps prevent the water from freezing in cold temperatures and boiling in hot temperatures, making it more suitable for use as engine coolant.
In the experiment, excess HCl was added to ensure that all KHCO3 was reacted. Excess reactants ensure that all of the limiting reactant is completely consumed in the reaction, leaving none unreacted. When all KHCO3 reacts, the reaction reaches completion.
The independent variable in this experiment is the amount of table salt added to the boiling water. The effect of adding salt to the water is to raise the boiling point of the water, therefore increasing the temperature at which the water boils.
The reaction is:CaO + H2O = Ca(OH)2Calcium hydroxide is a white precipitate.
Alcohol is added in the experiment to act as a solvent, helping to dissolve the substances being tested. Its purpose is to facilitate the mixing of the components and ensure a homogeneous solution for accurate measurements and observations.
To make an observation is to watch the subject in question, for example if you were watching a bird, you would make observations as to what kinds of noises it makes, where it lives, does it have any chicks, what does it eat....those are all different kinds of observations. While performing an experiment, observations may include smells, weighing the object, what happens when another thing is added to the solution or whatever.

They weren't added as much as they were discovered to exist. They were added to the science books as observations were made that verified their existence.
scientist make observations and evaluate they data to find new information
A suffix in an experiment refers to affixes added to the end of a word or a symbol that modifies its meaning or creates a new word or symbol. Suffixes can alter the tense, form, or part of speech of a word, providing additional context to the experiment.
First pour the water.

John Sherwen has written: 'Observations on the diseased and contracted urinary bladder, and frequent painful micturition; ... To which are added, Observations on the schirro-contracted rectum, ... By John Sherwen, M.D. ..'
Noah Webster included the word knit in his Compendious Dictionary of the English language published in 1806. Don't believe it had to be added as it was included in the first dictionary that I am aware of.
Some of the substance may be boiled off into the air (depending on the experiment) and cannot be weighed after the experiment is finished.
