Answer:
Starch is a viable indicator in the titration process because it turns deep dark blue when iodine is present in a solution. When starch is heated in water, decomposition occurs and beta-amylose is produced
Answer:
2
Step-by-step explanation:
The formula for the most stable form of oxygen is O₂, so the subscript is 2.
However, there is a less stable form of oxygen called <em>ozon</em>e. Its formula is O₃, so the subscript for ozone is 3.
Frost wedging happens when water gets in crack, freezes, and expands. This process breaks rocks apart. When this process is repeated, cracks in rocks get bigger and bigger and may fracture, or break, the rock.
Hope this helps :)
The neutral atom also has 20 electrons, but to form the 2+ ion, it needs to lose 2 of these, giving just 18 electrons. A neutral calcium atom has 20 protons and so 20 electrons. A calcium ion has a 2+ charge so it has lost 2 electrons. It has 20 protons and 18 neutrons.
Answer:
Electromechanical waves are defined as the waves which resulting from the interaction of magnetic fields, and oscillating electric. Some examples of these electromechanical wave are infrared, microwave, ultraviolet, visible, etc.
When these waves are arranged in the order of increasing wavelength then it's called an electromagnetic spectrum, and
spectral regions in order of increasing wavelength, we will get is:
Ultraviolet<visible<infrared<microwave.
