Answer: In the three-dimensional structure of methane, CH₄, the hydrogen atoms attached to a carbon atom are aligned <span>
<u>at the corners of a Tetrahedron</u>.
Explanation: In
Methane (CH</span>₄) the central atom (carbon) is bonded to four hydrogen atoms. So, the central atom is having four electron pairs and all pairs are bonding pairs and lacks any lone pair of electron. According to
Valence Shell Electron Pair Repulsion (VSEPR) Theory the central atom with
four bonding pair electrons and
zero lone pair electrons will attain a
tetrahedral geometry with
bond angles of 109°. Hence, the shape of CH₄ is tetrahedral.

Please check attachment
Explanation:
Here in this question question, we are concerned with writing the Lewis structure for the given molecule.
The Lewis structure is simply using dots to represent electrons which are not involved in the bonding.
That is, we shall be using dots to represent the non-bonding pairs of electrons around the atoms which are central.

The answer is Mineral,rock,sedimentary rock
Answer: moles
Explanation: Boyle's law:
Boyle's law stated that volume and pressure are inversely proportional to each others by keeping the number of moles and temperature constant.
Mathematical expression:
P₁V₁ = P₂V₂ (n and T are constant)
Charles's law:
Charles's law stated that temperature and volume are directly related related to each others by keeping number of moles and pressure constant.
Mathematical expression:
V₁/T₁ = V₂ /T₂ (n and P are constant)
Gay-Lussac's law:
This law stated that pressure of gas is directly related to its temperature by keeping the number of moles and volume constant.
Mathematical expression:
P₁/T₁ = P₂ /T₂ (n and V are constant)
<h3><u>Answer;</u></h3>
Covalent bond
<h3><u>Explanation;</u></h3>
- Bonding atoms with similar electronegativity values form covalent bonds.
- Covalent bond is a type of bond that forms as a result of sharing of eleetrons between atoms. It involves non-metal atoms.
- Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons
- <em><u>Pure covalent bonds result when two atoms of the same electronegativity bond.</u></em><em> This occurs only when two atoms of the same element bond with each other.</em>
- <em><u>When the electronegativity difference is greater than 2.0, the bond is considered ionic.</u></em>
