when you take 10 grams of salt, and dissolve it in 25 grams of hot water what is the solubility
Answer:
When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules. ... Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together.

What is wrong with writing the electron configuration of a ground state atom as 1s2 2s2 2p6 3s2 3p6 3d10 4s2 ?
Answer:
Writing of the subshells
Explanation:
Given configuration:-
[tex]\\ \sf\longmapsto 1s^22s^22p^63s^23p^63d^{10}4s^2[/tex]
Actual configuration:-
[tex]\\ \sf\longmapsto 1s^22s^22p^63s^23p^64s^23d^{10}[/tex]
This is because 4s orbital is less in energy than that of 3d

What is the molarity of 48.6 g of magnesium (Mg) ions in 4 L H2O? Show cancelation of units to get credit. PLEASE HELP!!!
Answer:
0.50M (1 sig. fig.)
Explanation:
The problem objective is 'Molarity (M)', so set up given data to reduce to moles per liter. That is ...
Molarity = moles Mg/Liters of solution = (48.6g/24.31g·mole⁻¹)/(4Liters) = 0.499794323M (calc. ans.) ≅ 0.5M (1 sig. fig.)
the chemical bond between elements of the two terminals of the periodic table is
Answer:
Covalent bonds are much more common in organic chemistry than ionic bonds. A covalent bond consists of the simultaneous attraction of two nuclei for one or more pairs of electrons. The electrons located between the two nuclei are bonding electrons.

What would be the freezing point of a solution that has a molality of 1.324 m which was prepared by dissolving biphenyl (C12H10) into naphthalene
The freezing point of a 1.324 m solution, prepared by dissolving biphenyl into naphthalene, is 71.12 ° C.
A solution is prepared by dissolving biphenyl into naphthalene. We can calculate the freezing point depression (ΔT) for naphthalene using the following expression.
[tex]\Delta T = i \times Kf \times m = 1 \times 6.90 \°C/m \times 1.324m = 9.14 \°C[/tex]
where,
i: van 't Hoff factor (1 for non-electrolytes)Kf: cryoscopic constantm: molalityThe normal freezing point of naphthalene is 80.26 °C. The freezing point of the solution is:
[tex]T = 80.26 \° C - 9.14 \° C = 71.12 \° C[/tex]
The freezing point of a 1.324 m solution, prepared by dissolving biphenyl into naphthalene, is 71.12 ° C.

Balancing Chemical Equation
C=H2=CH4
Answer:
C + 2H2 ⇒ CH4
Explanation:
In order to balance a chemical equation you need to make sure that the number of atoms on both sides are equal
C + H2 = CH4
C = 1
H = 2
Products:
C = 1
H = 4
H2 = 2 × 2 = 4
C + 2H2 ⇒ CH4

what is the molarity of an acetic acid solution if 25.0mL of the Hc2H3O2 solution is titrated with 29.7 mL of a 0.205 M KOH solution
The molarity of the acetic acid, HC₂H₃O₂ solution is 0.244 M
We'll begin by writing the balanced equation for the reaction
HC₂H₃O₂ + KOH —> KC₂H₃O₂ + H₂O
From the balanced equation above,
The mole ratio of the acid, HC₂H₃O₂ (nA) = 1
The mole ratio of the base, KOH (nB) = 1
From the question given above, the following data were obtained:
Volume of the acid, HC₂H₃O₂ (Va) = 25 mL
Volume of the base, KOH (Vb) = 29.7 mL
Molarity of the base, KOH (Mb) = 0.205 M
Molarity of the acid, HC₂H₃O₂ (Ma) =?MaVa / MbVb = nA/nB
(Ma × 25) / (0.205 × 29.7) = 1
(Ma × 25) / 6.0885 = 1
Cross multiply
Ma × 25 = 6.0885
Divide both side by 25
Ma = 6.0885 / 25
Ma = 0.244 MTherefore, the molarity of the acetic acid, HC₂H₃O₂ solution is 0.244 M
