The solute will dissolve quicker if the solute is more?A. shaken.
B. saturated.
C. cooled.
D. settled.
Answers
Answer:
A) Shaken is the correct answer
Explanation:
The other three don't fit in with the solution if you think about it. When you shake something with lemonade crystals (Like a lemonade flavor packet in poured in a water bottle) it dissolves faster when you shake it rather than it sit on the bottom for 15 minutes! :) .
Hope this helps! :)

Answer: Compounds having the same empirical formula are:
Explanation:
Empirical formula tells us about the proportion of the elements present in the compound but it do not tells us about the actual numbers of atoms of the elements present in the compound.
In given empirical formula that is proportion of C:H:O = 1:2:1
In the proportion of C:H:O =2:4:2= 1:2:1
In the proportion of C:H:O =3:6:3= 1:2:1
In the proportion of C:H:O =1:2:2= 1:2:2
In the proportion of C:H:O =5:10:5= 1:2:1
In the proportion of C:H:O =6:12:6= 1:2:1
Compounds having the given empirical formula are:
The chemical compounds that have the empirical formula are:
A.C2H4O2
B.C3H6O3
D.C5H10O5
E.C6H12O6
An empirical formula can be defined as a formula that gives the smallest and simplest whole number ratio of the atoms of a chemical element found in a chemical compound.
The simplest whole number ratio of the atoms of is:
= 1:2:1
- 1 atom of carbon.
- 2 atoms of hydrogen molecule.
- 1 atom of oxygen.
For :
= 2:4:2 = 1:2:1
For :
= 3:6:3 = 1:2:1.
For :
= 1:2:2 = 1:1:1 (Incorrect)
For :
= 5:10:5 = 1:2:1
For :
= 6:12:6 = 1:2:1
Note:
- C is the chemical symbol of carbon.
- H is the chemical symbol of hydrogen.
- O is the chemical symbol of oxygen.

What are the 4 types of electron configuration?
The 4 special types of orbitals (s,p,d, and f) have distinctive shapes, and one orbital can hold a most of twoelectrons. The p, d, and f orbitals have different sublevels, accordingly can keep extraelectrons. As stated, the electronconfiguration of each detail is precise to its position on the periodic table.
In atomic physics and quantumchemistry, the electronconfiguration is the distribution of electrons of an atom or molecule (or different bodily structure) in atomic or molecularorbitals.

If you search Google images for "Aufbau principle periodic table," you'll find some handy diagrams that will make it much easier to determine an element based on its electron configuration. Determine the number of electrons in the last part of the configuration (in this case, 5), locate that group on the Aufbau periodic table diagram, then count that number from left to right within that group. In this case, within the "3p" portion of the Periodic table, count to 5 and you'll find Chlorine as the answer.

51)
Mg(s) + N₂(g) --> Mg₃N₂(s)
There is one Mg atom on the reactant side and three Mg atoms on the product side. So to balance the number of Mg on both side of the equation a coefficient 3 is placed before Mg on the reactant side. The number of N atoms are two on both side of the reaction. Therefore the balanced chemical equation is,
2Mg(s) + N₂(g) --> Mg₃N₂(s)
52)
The electron configuration of Mg is 1s²2s²2p⁶3s² or [Ne]3s²
The electron configuration of Mg²⁺ is 1s²2s²2p⁶ or [Ne]
The electron configuration of Ne is 1s²2s²2p⁶
Ne he same electron configuration as a Mg²⁺ ion.
53)
Mg has its valence electron in the 3s shell, but Mg²⁺ has no electron in the 3s shell, the valence electron in Mg²⁺is in the 2p orbital. The size of the 2 shell is smaller than the 3 shell. Hence, Mg²⁺ is smaller than Mg.
The balanced equation for the reaction between magnesium and nitrogen is 3Mg(s) + N2(g) -> Mg3N2(s). Neon has atoms with the same electron configuration as a magnesium ion. When an atom of a metal forms an ion, it loses electrons and has a smaller radius.
51. The balanced equation for the reaction between magnesium and nitrogen is:
3Mg(s) + N2(g) → Mg3N2(s)
52. The magnesium ion has the same electron configuration as a neon atom because both have the electron configuration of 2,8. Therefore, neon is the noble gas with atoms having the same electron configuration as a magnesium ion.
53. When an atom of a metal forms an ion, it loses one or more electrons to achieve a stable electron configuration. This results in a decrease in the size of the ion compared to the neutral atom. The loss of electrons reduces the repulsion between the remaining electrons, causing the ion to have a smaller radius.
