The soda contains CO2 that is dissolved CO2 reacts with water
CO2+H2O--->H2CO3
to form carbonic acid
this is a weak acid but it gives protons to water
H2CO3+H2O-->-HCO3+H30+
pH=-lg[H3O+]
[H3O+] is the molar concentration
Therefore the acid present in the solution causes the pH to be lower than 7. It can either be the H2CO3 if it is a carbonated beverage or citric acid from lime juice.
Starch molecules present in maple tree ............................................. from the external environment as INORGANIC COMPOUNDS.
Starch is made in the maple tree during the process of photosynthesis. The inorganic substances that are used during the process of photosynthesis are carbon dioxide and water; these two are mixed together in the presence of sunlight to form carbohydrates.
i think the answer is "Rocks are made up of many different minerals that are bound together"
The step of the scientific method being described in the example is collecting and observing the data. This is an important part of the experiment, as it is going to be the basis of the analysis and conclusion. This is where the actual application of the hypothesis is going to reflect on. The data noted by the observer should be accurate and genuine.
