What is the formula for mass and volume? Between 5 degrees Celcius and 10 degrees Celcius, which solute shows the greatest change in the amount that can be dissolved in 100 grams of water? The volume of a piece of metal is 10mL and mass is 15g, what will it's density be?
The density of the substance is the ratio between a specified mass of that substance and its corresponding volume. The density of a mass will work for any mass with a corresponding volume since density is specific to the substance in consideration. Densities have no unique unit ...
What is the molarity of a solution made by dissolving 26.42 g of (NH4) 2 SO4 in enough water to make 50 mL of solution? How can you increase the solubility of a solution? If the mass of the solute increases, does the solubility increase?
but first, let me explain it from a slightly different perspective, Recall from the dogs’ point of view. Sometimes changing YOUR perspective is what needs to be done. Let’s start with the basics: How do you call your dog? What tone of voice do you use to call the dog? Samurai ...
Mg is a metal forms a cation with +2 ox Ionic compound with cris-cross: MgCl2 Given different pairs of atoms, how would you decide which has the most polar bond? I would first deal with covalent vs ionic Non-metals with non-metals = covalent Metals with non-metals = ionic If I was...
