Answer:
Its number of protons is the answer. I did a test on this. Hope it helps :)
Answer:
Water is a solvent, and CO2 gas and the powdered drink mix are both solutes.
Explanation:
In order to successfully answer this question, we need to remember that solutions consist of solutes and solvents.
Solutes are components of solutions that are dissolved (typically ionic salts if we have a polar solvent), while solvents are fluids (usually liquids) that provide a medium for the solutes to dissolve (water is the most common polar solvent for ionic salts, for example).
As a general rule, solvent is used in great excess, that is, it makes the greatest percentage in terms of mass of a particular solution.
Applying the theory above for this problem, notice that the greatest percentage of this solution belongs to water, besides, water is a common solvent in general. Thus, it is our solvent.
Also, solution would only have one solvent and one or several solutes. This leaves the two other components, carbon dioxide and powdered drink mix, as our solutes, as they have a lower percentage than our solvent.
Answer:
yes It can because it can be changed by any property
volume is mass divide by density
100/0.8= 125mL
Answer:
Quantum mechanical atomic model.
Explanation:
The first model of electronic configuration was given by Bohr's model.
The most accurate model of electronic configuration is the quantum mechanical atomic model.
Bohr's model has various limitations:
1. It does not explain the Zeeman effect and stark effect.
2. It is not valid for multi-electron system.
3. Heisenberg uncertainty principle is not followed by this model
The quantum mechanical atomic model explains all the four quantum numbers for the electronic configuration of an atom in the periodic table.
The quantum mechanical atomic model considered the Heisenberg uncertainty principle.
