It is the control group of the experiment. It provides a normal standard which the results of the experimental groups can be compared against.
the weak chemical attraction is Hydroden bond while the stronger one is the Ionic bond
In a chemical equation, each element has a symbol (in the periodic table in the elements). You use those symbols to create a chemical equation. For example, water is H2O. "H" represents Hydrogen, "O" represents Oxygen and the 2 means that there are two oxygen particles for each oxygen particle. Together, this creates one water molecule.
Oxygen concentration in water can be tested using a dissolved oxygen meter or a chemical test kit. The dissolved oxygen meter measures the amount of oxygen dissolved in the water, while a chemical test kit uses reagents to indicate the oxygen level based on a color change. Both methods provide an accurate assessment of oxygen concentration in water.
The hypothesis of purifying water is that the chosen purification method, such as filtration or chemical treatment, will effectively remove contaminants and pathogens from the water, making it safe for consumption. This hypothesis can be tested through experiments that measure the water quality before and after purification to assess its effectiveness.
a molecule or compound. Each element is represented by its chemical symbol (e.g. H for hydrogen), and the number of atoms of each element is denoted by a subscript following the symbol (e.g. H2O for water).
if there been many chemical changes in the water then it's chemical properties each time will be different and we may not call it water then. it would be a formation of each time , a new compound.....
The chemical commonly used for testing chlorine in water is sodium thiosulfate. This chemical is added to water samples that are being tested for chlorine content to neutralize the chlorine and allow for accurate measurement using colorimetric methods.
You can be tested for multiple chemical sensitivity by being tested for sensitivity using the chemicals that you have deemed relevant by your doctor. You can learn more about this condition at the Wikipedia.

The chemical signature for water is H2O, indicating that each molecule of water is composed of two hydrogen atoms and one oxygen atom.
the weak chemical attraction is Hydroden bond while the stronger one is the Ionic bond
This percentage is different for each chemical compound.
To start with a base result.
It refers to the atoms in a molecule of the chemical compound. For example, water's chemical formula is H2O, which means that there are 2 hydrogen atoms and 1 oxygen atom in each molecule of water.

H 2 0 That is one part hydrogen and two parts oxygen
no. The chemical compound in pot that is tested for is THC and its metabolites, while the chemical compounds tested for with adderall are amphetamines and their metabolites. COMPLETELY different drugs.
