What neutralizes bleach in water? Pour 1 cup of 3 percent hydrogen peroxide into the water. Ascorbic acid (chemical formula C6H8O6) is used commercially to neutralize bleach in water storage tanks. Bleach, which is added to water tanks as a disinfectant, needs to be completely eliminated before the water is fit for drinking or agricultural […]
Which outcome is the main function of the light-dependent reactions of photosynthesis?
Which outcome is the main function of the light-dependent reactions of photosynthesis? The overall function of light-dependent reactions is to convert solar energy into chemical energy in the form of NADPH and ATP. This chemical energy supports the light-independent reactions and fuels the assembly of sugar molecules. The light-dependent reactions are depicted in (Figure). What […]
Is heat needed in chemical change why?
Is heat needed in chemical change why? Chemical reactions involve the production of new materials which are quite different from the reacting substances. Any new materials come from the reacting substances. While heat is often necessary to initiate a chemical reaction it is not always necessary. Chemical reactions are used to produce most of our […]
What will happen if two hydrogen atoms combine?
What will happen if two hydrogen atoms combine? Thus, two Hydrogen atoms combine to form a Hydrogen molecule. The number of protons in the atomic nucleus is equal to the number of electrons revolving around that nucleus. This means that the positive electric charge is balanced by the negative. The atom is therefore electrically neutral. […]

Table 2 – Long Working Distance Objectives Designation Magnification Working Distance ELWD 100x 2.0 mm SLWD 10x 20.3 mm SLWD 20x 20.5 mm SLWD 50x 13.8 mm What happens if you try to use the coarse adjustment when the 10X lens? What happens if you […]
What is the 7 Universal Laws?
What is the 7 Universal Laws? To name them, they are the Laws of Mentalism, Correspondence, Vibration, Polarity, Rhythm, Cause and Effect and Gender. Once you understand, apply and align yourself with these seven Universal Laws, you will experience transformation in every area of your life beyond what you have ever dared to imagine. What […]
Why do fizzy tablets dissolve faster in hot water?
Why do fizzy tablets dissolve faster in hot water? In the hot water the tablet should have more vigorously produced bubbles than in the cold water. The higher the temperature, the faster the molecules move—and the more likely it is that the bicarbonate will contact hydrogen in just the right way for the chemical reaction […]
What animals live in a cave?
What animals live in a cave? Extant trogloxene animals include rats, raccoons, opiliones, and bears. During the third interglacial epoch and the fourth glacial advance, a large number of now extinct species inhabited the caves of the world. Cave bears, cave leopards, cave lions, and cave hyenas are examples of these extinct animals. Can you […]
Why does the filament in a light bulb glow more brightly when an electric current is slowly increased?
Why does the filament in a light bulb glow more brightly when an electric current is slowly increased? 4.As the electric current in a lightbulb is slowly increased, the filament glows more and more brightly. Why does this happen? As the current increases, the electrons more frequently bump into more atoms of the resistor (filament) […]
What are the five properties of alkalis?
What are the five properties of alkalis? Chemical Properties of Alkalis Alkalis react with Acids to form salt and water. This reaction is called neutralisation reaction. Alkalis react with ammonium salts to form salt, water and ammonia gas. Alkalis react with solution of metal salt to form another metal salt and hydroxide. What are the […]
