Why is chemical change not easily reversible? chemical change never reversed because it produce new substance after reaction which is not reversible . if it is reversed , it can’t called chemical reaction , it called physical reaction. Is a chemical change reversible? In principle, all chemical reactions are reversible reactions . This means that […]

Does higher volume mean higher density? Density is determined by an object’s mass and volume. If two objects take up the same volume, but have one has more mass, then it also has a higher density. It is about how heavy something is compared to the same amount (volume) of water. Are volume and mass […]

What do you do if you hit black ice? Deal with a black ice encounter. If you do hit black ice, your first reaction must be to remain calm and avoid overreacting. The general rule is to do as little as possible and allow the car to pass over the ice. Do not hit the […]

What is the ratio of molecules in 1 mole? 1 mole of any compound is the Avogadro’s number, 6.023×1023 . And, 1 mole of HNO3 = 6.023×1023 molecules. Now, both compounds have the same number of molecules. The ratio of molecules between both the compounds is 1:1 . Which is the correct formula to calculate […]

How do I choose a motor controller? Choosing a Motor Controller The first consideration is the motor’s nominal voltage. Once you have found a range of controllers that can power the motor with the appropriate voltage, the next consideration is the continuous current the controller will need to supply. The Control method is another important […]
