The labels the table to indicate when each statement Is true. Labels can be used once, more than once, or not at all, The orange dye moves independently of the purple dye. 2. Concentration gradients exist that drive diffusion of both dyes. : <u>free water, solute, free water, solute.</u>
In chemistry, attention is the abundance of a constituent divided by way of the total quantity of an aggregate. several types of mathematical descriptions may be prominent: mass concentration, molar concentration, range concentration, and quantity concentration.
it's miles the amount of solute dissolves in one hundred g solvent. If the attention of the answer is 20 %, we understand that there are 20 g solutes in one hundred g solution. instance: 10 g salt and 70 g water are mixed and the solution is ready. find awareness of the answer by means of percentage mass.

Question 1. What one factor identifies an atom as a specific element? Answer: the number of protons. Remember that the atoms of a same element have the same number of protons, and the atoms of different elements cannot have the same number of protons. That permits to order the elements according to the atomic number (number of protons) in the periodic table. Question 2.An atom of fluorine has an atomic number of 9 and an atomic mass of 19. The atom contains Answer: 9 protons, 9 electrons, and 10 neutrons : because the atomic number is the number of protons, the number of electrons must be equal to the number of protons (because the atom is neutral), and the mass number is the number or protons plus the number of neutrons: 9 protons + 10 neutrons = 19 mass number (atomic mass). Question 33.Experiments with cathode ray tubes led to a new model of the atom, sometimes called the \"plum pudding\" model, because of the discovery of the <span>. Answer. electron ... when electron was discovered JJ Thompson proposed the plum pudding model, in which the atom was a solid positively charged sphere with electrons distributed inside it.</span>
