Since there are several open channels, the membrane is permeable to K+ when at rest. The equilibrium potentials for sodium (ENa) and potassium (ENa) are +60 mV and 90 mV, respectively.
The main determinant of the resting membrane potential is K+ permeability. The permeability of Na+ Although it contributes, the resting membrane potential is not primarily determined by this factor.-70 mV membrane potential: The cell's resting membrane potential-90 mV membrane potential: the time when neither a net inflow nor an outflow of K + occurs in the cell.The membrane is more permeable to potassium than sodium while it is at rest because significantly more potassium channels are open than sodium channels.

when 20.87 g of propane is combusted in excess oxygen, how many grams of co2 are produced and how many grams of o2 are consumed?
When 20.87 g of propane is combusted in excess oxygen 62.577g of co2 are produced and 75.89grams of o2 are consumed
What are combustion reactions?
combustion is a chemical reaction between two or more chemicals, usually involving oxygen, that produces heat and light in the form of a flame. When a material reacts quickly with oxygen, a combustion reaction happens (O2).
During the combustion of propane the following reaction occurs:
C3H8(g)+5O2(g)→3CO2(g)+4H2O(l)
We know that the combustion of 1 mole of propane gives 3 moles of carbon dioxide.
= 20.87 g/44.10⋅g⋅mol−1=0.473⋅mol
And since, per the stoichiometric equation, if 0.200⋅mol propane is completely combusted, 3×0.473mol×44.10⋅g⋅mol−1=62.5779g
Oxygen consumed can be considered as x
44x=20.87x160=75.89g
Therefore when 20.87 g of propane is combusted in excess oxygen 62.577g of co2 are produced and 75.89grams of o2 are consumed.

Which of the following statements correctly describe bonding and intermolecular forces?
Intermolecular forces involve partial or small charges that are far apart and are relatively weak
Bonding forces occur within the nucleus of the atom and are therefore strong
Covalent bonds are type of intermolecular force since they are found in molecules.
Bonding forces are generally much stronger than intermolecular forces
For molecular substance, the strength of the Intermolecular forces determines the physical properties of its phases
The correct statements are thus: bonding forces are typically much stronger than intermolecular forces, intermolecular forces involve partial or small charges that are far apart and are relatively weak, and for molecular substances, the strength of the intermolecular forces determines the physical properties of its phases.
What does bonding mean in chemistry and its types?When two or more atoms, molecules, and ions join together chemically to form a compound, this process is known as chemical bonding. These chemical bonds hold the atoms in the resulting molecule together.
The four main types of bonding—ionic, covalent, metallic, and molecular—are discussed in this section. Ice is a different kind of solid that plays a significant role in a few crystals.
How bonding is formed and its purpose?To form bonds, atoms exchange or trade their valence electrons. The electrons in an atom's outermost energy level known as valence electrons have the potential to interact chemically. All chemical bonds are built on valence electrons.
The simplest explanation is that atoms are attempting to achieve the most stable (lowest-energy) state possible. Many atoms become stable when they satisfy the octet rule or have their valence shell completely filled with electrons.

a 15.0-ml sample of an electroplating solution is analyzed for its sulfuric acid concentration. it takes 52.6 ml of the 0.583 m to neutralize the sample. find the molarity of the sulfuric acid.
The molarity of the sulfuric acid from a 15ml sample of an electroplating solution is 1.022 M
It is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per liters of a solution. Molarity is also known as the molar concentration of a solution.
How to calculate the molarity of the sulfuric acid?
Based from the rule of acidimetry and alkalimetry
The formula is :
V₁ * S₁ = V₂ * S₂
where
V₁ = 15ml
V₂ = volume of alkali solution = 52.6ml
S₁ = strength of acid solution in normality = unknown
S₂ = strength of alkali solution in normality = 0.583M (Because NaOH normality and molarity has the same value)
Now, let's go back to the formula
15 * S₁ = 52.6 * 0.583
S₁ = 30.6658 / 15
= 2.044N
The molarity of the sulfuric acid is
2.044 / 2 = 1.022 M H₂SO₄ (divided by 2 because H₂SO₄ is a dibasic acid)
So the molarity of sulfuric acid is 1.022 M.

3) hydrogen bond (strong),that is an severe kind of dipole dipole interplay among partly nice hydrogen & partly negative oxygen withinside the methanol(CH3OH) molecule
The CH2O molecules can shape London forces and dipole/dipole forces.(True)
Formaldehyde(CH2O),like several atoms and molecules, may have very vulnerable London dispersion forces created as electrons shift withinside the electron cloud.as it possesses a everlasting dipole (primarily based totally at the polarized carbon-oxygen bond) formaldehyde additionally famous dipole-dipole interactions.

construct an orbital diagram to show the electron configuration for a neutral magnesium atom, mg.
The orbital diagram of magnesium (Mg) shown below:
What is orbital diagram?The electrons in an atom are depicted in orbital diagrams in visual form. For creating orbital diagrams, three guidelines are helpful. Each electron resides in the orbital with the lowest energy, in accordance with the Auf Bau Principle. There may be only two electrons in a single orbital, according to the Pauli Exclusion Principle.
An orbital diagram, often known as an orbital box diagram, is a visual representation of an atom's electron arrangement. The electrons occupying the orbitals are shown as arrows (or half-arrows).
Mg have 12 electrons in the neutral atom
so the electronic configuration of the Mg is: 1s² 2s² 2p⁶ 3s²
