An indicator shows where the endpoint of a titration is. Different indicators will change colors at different equivalence points. Phenolphthalein will change colors at around pH7.5 or so, and others like Methylene Blue will change around a pH of 6. Different titrations will have different pH's at different equivalence points.
No, phosphorus is not a metal, In fact, it is a non metal which means that it isn't metal. If you look at the periodic table, the word phosphorus, is in group 15.
Answer:
The cell's volume will remain stable.
Explanation:
If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell's volume will remain stable. If the solute concentration outside the cell is the same as inside the cell, and the solutes cannot cross the membrane, then that solution is isotonic to the cell.
The best option in here is the mass defect. This is so because the mass defect is the difference between the particles of the nucleous weight and the nucleous itself. According to the equation <span>E=mc^2, the mass defect is related the the binding theory. In order to calculate the mass defect of an atom you need to add up the masses of each proton and each of neutron that are present in the nucleus and then you substract the actual mass of the nucleus from the combined mass. That is why in mass defect you need the information given in your question. </span>
I'm not sure what "mole" is but I am gonna assume molar so "Molar" mass is the mass of a given substance divided by the amount of that substance, measured in g/mol. For example, the atomic mass of titanium is 47.88 amu or 47.88 g/mol. In 47.88 grams of titanium, there is one mole, or 6.022 x 1023 titanium atoms.
have a good day hope this helps
