What are the two types of mixture and substance? A mixture is made when two or more substances are combined, but they are not combined chemically. There are two main categories of mixtures: homogeneous mixtures and heterogeneous mixtures. Is oil and water a heterogeneous mixture? By definition, a pure substance or a homogeneous mixture consists […]
Does higher volume mean higher density?
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 is ionized helium?
What is ionized helium? Singly ionized helium is an atom that has lost one of its electrons. We must expect its remaining electron to act like a hydrogen electron. There is only one difference between a hydrogen atom and a singly ionized helium atom; number of protons in the nucleus, so the nuclear charge. What […]

What is the ratio of molecules in 1 mole?
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 […]
What is the principle of serial dilution?
What is the principle of serial dilution? Serial dilution is a common technique used in many immunologic procedures. A small amount of serum or solute can be serially diluted by transferring aliquots to diluent. One of the most common series doubles the dilution factor with each transfer (1:2, 1:4, 1:8 …). What is the advantage […]
How do I choose a motor controller?
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 […]
