what type of bonding orbital is always formed between hydrogena nd another atom in a covalent compound
Answers
When hydrogen forms a covalent bond with another atom, it typically forms a sigma (σ) bond. A sigma bond is a type of covalent bond.
A sigma bond is a type of covalent bond that is formed by the overlap of atomic orbitals along the axis connecting the two atoms. Sigma bonds are the strongest and most stable types of covalent bonds, and they are responsible for the majority of the bonding in most molecules.
In the case of hydrogen, the sigma bond is formed by the overlap of the 1s orbital on the hydrogen atom with an orbital on the other atom. The 1s orbital is the lowest energy orbital on the hydrogen atom and is characterized by a spherical shape. When hydrogen forms a covalent bond with another atom, the sigma bond is typically the only bond that is formed. It is important to note that hydrogen can also form other types of bonds, such as pi (π) bonds, which are formed by the overlap of atomic orbitals perpendicular to the axis connecting the two atoms. However, these types of bonds are less common and are typically weaker than sigma bonds.

How to Write the Name for Ionic Compounds
ex Sodium plus fluoride
Answers
Ionic compounds typically consist of a metal (cation) and a non-metal (anion) element, and they form a strong bond due to the transfer of electrons.
To write the name of ionic compounds, follow these steps:
1. Identify the cation (positive ion) and anion (negative ion) in the compound. In your example, sodium is the cation and fluoride is the anion.
2. Write the name of the cation first, which is "sodium" in this case.
3. Next, write the name of the anion, but replace the ending with "-ide." For fluoride, it becomes "fluoride."
4. Combine the names of the cation and anion. In this example, the ionic compound's name is "sodium fluoride."
Remember that ionic compounds typically consist of a metal (cation) and a non-metal (anion) element, and they form a strong bond due to the transfer of electrons.

Answer:
The object has to move a distance when a force is applied to it
Explanation:
For work to be done on a body the force applied must move the body through a particular distance.
Work done = Force x distance
If no distance is moved by the force, no work is done.
Also, the angle between the force and the distance must be 0 to do the maximum work on the body.
In a presentation about measuring mass, one of your classmates states, "Two objects of the same size will always have the same mass.” Is this statement correct? Why or why not?
Answers
Answer:
The statement is not correct.
Explanation:
If two objects have the same mass, their respective densities determine their volumes. By definition, density = mass/volume or volume = mass/density. Therefore if two objects have the same mass, the mode dense object (with higher density) will occupy less volume than the other object.

What is the molar mass of a gas that fills a 1.20l container at a temperature of 305k. the gas has a mass of 1.98g and the container is at a pressure of 0.960 atm.
Answers
Answer:
The molar mass of the gas should be 43.0 g/mol.
Explanation:
1.Use the ideal gas law(\(PV=nRT\)) & the formula for moles and molar mass(\(n=m/M\)).
2.Insert the equation \(n=m/M\) into \(PV=nRT\) and re-arrange to solve for M(molar mass). \(M = mRT/PV\)
3.Insert values and use the gas constant R = \(0.082 (L * atm)/(K * mol)\) since the volume is in liters and the pressure is in atmosphere units.
\(M = mRT/PV = \frac{(1.98g)(0.082 L*atm/(K*mol))(305 K)}{(0.960 atm)(1.20 L)}\)
4. Your answer should be 42.99 g/mol or 43.0 g/mol.

If we look at the periodic table we will see that P belongs to group 15 or 5A. That means that it has 5 valence electrons.
Br belongs to 17 or 7A. That means that it has 7 valence electrons.
Our molecule is PBr₃. One molecule of it has 1 atom of P and 3 atoms of Br. Each atom of Br has 7 valence electrons and the atom of P has 5 valence electrons.
Electron count = 1 * 5 + 3 * 7
Electron count = 26 valence electrons.

Answers
Answer:
An area around a molecule that describes a region of space where the electrons that are shared between bonded atoms can reside
Explanation:
A molecular orbital is an area around a molecule that describes a region of space where the electrons that are shared between bonded atoms can reside.
Molecular orbitals are formed by linear combination of atomic orbitals of about the same energy. The number of atomic orbitals that are combined to give molecular orbitals is the same as the number of molecular orbitals formed. The build up of electrons in molecular orbitals also follow the Aufbau principle, Hund's rule and Pauli exclusion principle.
Which metal is likely to be more reactive? Mg or Rb

Answers
Answer: Rb is more reactive
Explanation: The reason rubidium is more reactive is because it loses its valence electron more readily than Mg does.
Answer:
Rb
Explanation:
Mg has 2 valence electrons to loose vs Rb has 1 valence electron to loose.
Rb wins because losing 1 electron is easier than having to lose 2, which means Rb is more reactive ("ready" to react).
a buffer solution is composed of 0.100 m ha, a weak monoprotic acid, and 0.310 m naa, the sodium salt of the acid. the solution has a ph of 3.80. what is the ka of the weak acid, ha?
Answers
If the solution has a pH of 3.80, then the Ka of the weak acid, HA, is approximately 1.22 x 10⁻³.
To determine the Ka of the weak acid HA, we can use the Henderson-Hasselbalch equation:
pH = pKa + log ([A⁻]/[HA])
Where pH is 3.80, [A-] is the concentration of NaA (0.310 M), and [HA] is the concentration of the weak acid (0.100 M).
3.80 = pKa + log (0.310/0.100)
To solve for pKa, subtract the log term from the pH:
pKa = 3.80 - log (0.310/0.100)
Calculate the pKa:
pKa ≈ 2.91
Now, to find Ka, use the relationship:
Ka = 10^(-pKa)
Ka ≈ 10^(-2.91)
Ka ≈ 1.22 x 10⁻³
The Ka of the weak acid, HA, is approximately 1.22 x 10⁻³.
