How many moles of NaOH must be dissolved in 1.00 L of water to make NaOH (aq) with a pH of 12.2?
Answer:
1.58 102 mol
Explanation:
I just looked it up on Quizlet.
1.58 102 moles of NaOH must be dissolved in 1.00 L of water to make NaOH (aq) with a pH of 12.2.
How many moles are present in NaOH?One mole of any substance weighs about the same as the molecular mass of that substance. Hence, the number of moles of sodium hydroxide contained in 160 g of it is 4 moles.
How do I calculate moles?Number Of Moles Formula
1 The formula for the number of moles formula is expressed as.
Given.
2 The number of moles formula is.
3 The number of moles = Mass of substance / Mass of one mole.

What is the value for AG at 100 Kif AH = 27 kJ/mol and AS = 0.09 kJ/(mol-K)?
A. AG = 2700 kJ/mol
B. AG = -36 kJ/mol
C. AG = 0 kJ/mol
D. AG = 18 kJ/mol
Answer:
ΔG = 18KJ/mol
Explanation:
Given data:
ΔS = 0.09 Kj/mol.K
ΔH = 27 KJ/mol
Temperature = 100 K
ΔG = ?
Solution:
Formula:
ΔG = ΔH - TΔS
ΔS = entropy
ΔH = enthalpy
by putting values,
ΔG = 27 KJ/mol - 100K(0.09 Kj/mol.K)
ΔG = 27 KJ/mol - 9 KJ/mol
ΔG = 18KJ/mol
Answer:
ΔG = 18kJ/mol

Explain the electroplating process of an iron key with silver. the materials provided for electroplating is AgNO3 solution, silver rod and iron key.
Answer:
See explanation
Explanation:
The process of electroplating an iron key with silver involves electrolysis.
The anode is a silver rod, the electrolyte is AgNO3 solution while the cathode is the iron key. A battery is connected to provide energy to drive the non-spontaneous electrochemical reaction.
Electrons flow from the anode to the cathode. Silver ions from the silver rod replenishes the silver that is deposited on the iron key in order to continue the electrolytic process.
The silver anode is therefore depleted in mass while the iron key increases in mass.
An object is moving across a surface, but it does not gain or lose speed. Which best describes the object’s force?
Answer:
Explanation:
the vector sum of all such forces which equals zero for an object at rest. CASE 1: Considering a basketball of weight 1kg, if it has been kept stationary on the ground, there are two forces acting on it. These are it's weight (gravity) and equal and opposite force from the ground (normal reaction).
Answer:
The net force is zero. :)

Methane(CH4) is a gas at room temperature, Methanol (CH3OH) is a liquid. Explain why using types of intermolecular forces present.
Explanation:
Methane is a gas at room temperature but methanol is a liquid because in methane there's London dispersion intermolecular force but in methanol there's H-bond and London dispersion force. H-bond is more stronger than London dispersion force. So, it increases the boiling point of methanol that's why methane is gas at room temperature due to weak attraction of London dispersion force and methanol is liquid.
Methanol has a higher boiling point than methane due to stronger intermolecular forces (IMFs), or attraction between individual molecules. This makes its molecules more difficult to separate, requiring more energy and resulting in a higher boiling point.
What are intermolecular forces?An intermolecular force is a force that mediates the interaction of molecules, including electromagnetic forces of attraction or repulsion that act between atoms and other types of neighboring particles, such as atoms or ions.
Intermolecular forces are classified into five types namely,
Ion-dipole forces.Ion-induced dipole forces.Dipole-dipole forces.Dipole-induced dipole forces.Induced dipole forces.Between ions and polar dipole molecules, ion-dipole forces exist.
Since of stronger intermolecular forces (IMFs), or attraction between individual molecules, methanol has a higher boiling point than methane.
This makes it more difficult to separate its molecules, requiring more energy and resulting in a higher boiling point.
Thus, this is the reason of using types of intermolecular forces present.

What is the molecular formula of the compound with a molecular weight of 112 g/mol and percent composition: 85.6% C and 14.4% H?
Select one:
a. C2H4
b. CH2
c. C4H8
d. C8H16
Answer:
Molecular formula = C₈H₁₆
Explanation:
Given data:
Percentage of hydrogen = 14.4%
Percentage of carbon = 85.6%
Molecular formula = ?
Molecular weight = 112 g/mol
Solution:
Number of gram atoms of H = 14.4/ 1.01 = 14.26
Number of gram atoms of C = 85.6/ 12 = 7.13
Atomic ratio:
C : H
7.13/7.13 : 14.26/7.13
1 : 2
C : H = 1 : 2
Empirical formula is CH₂
Molecular formula:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
n = 112 / 14
n = 8
Molecular formula = n (empirical formula)
Molecular formula = 8 (CH₂)
Molecular formula = C₈H₁₆

how a neutral object is different from a negatively charged object.
Answer:
Charged objects have an imbalance of charge - either more negative electrons than positive protons or vice versa. And neutral objects have a balance of charge - equal numbers of protons and electrons. ... Their presence (or absence) will have no direct bearing upon whether an object is charged or uncharged.

Answer:
Hydrogen bond strengths range from 4 kJ to 50 kJ per mole of hydrogen bonds. In molecules containing N-H, O-H or F-H bonds, the large difference in electronegativity between the H atom and the N, O or F atom leads to a highly polar covalent bond (i.e., a bond dipole).
