When 1. 0 l of 0. 00010 m NaOH and 1. 0 l of 0. 0014 m mgso4 are mixed, there will be no precipitate formed.
<h3>What is a precipitate?</h3>
The precipitate is the solid concentration of a substance that is collected over a solution.
First, we determine the concentration of magnesium and hydroxide
(Mg2+) = 7.00 × 10⁻⁴
(OH−) = 5.00 × 10⁻⁵
Now, we calculate the solubility quotient
Qc = (Mg2+) (OH−) ²
Qc = 7.00 × 10⁻⁴ x (5.00 × 10⁻⁵)²
Qc = 1.75 x 10⁻¹²
The solubility product of the magnesium hydroxide is 1.80 x 10⁻¹¹ which is more than the solubility quotient. Thus, there will be no precipitate form.
Thus, there will be no precipitate formed because the solubility quotient we calculated is less than the solubility product.

Explanation:
Van der Waals interactions occur between any two or more molecules. They are caused by a fluctuation in electron density, as electrons are not actually fixed in a shell, but actually freely moving as a 'cloud of electron density'. This means that sometimes one end of a molecule can become more partially negatively charged as all electrons move to that side, and conversely it can attract the more partially positive end of a molecule (that has little electrons).
Hydrogen bonds only occur between molecules that contain oxygen, nitrogen and fluorine bonded to a hydrogen atom.
Hydrogen bonding is also the strongest intermolecular force there is, but not strong in comparison to ionic and covalent bonds. Therefore, hydrogen bonds are much stronger than Van der Waals forces. Hydrogen bonds only form if oxygen, nitrogen and fluorine are bonded to a hydrogen atom, as they have the greatest electronegativity differences (look at an electronegativity table), and when the overall molecule is polar (have unequal charges). This allows the molecule to be able to attract another molecule from one of the bonded atoms to a hydrogen atom.
Yes because it is a perfect conductor and all metals conduct heat.
<span>The nucleus is the organelle present in eukaryotic cells with the main function in the control of all cell activities and maintaining the gene integrity. Namely, it contains the genetic material of the cell in the form of chromosomes (DNA molecules in complex with proteins). It is enclosed by the nuclear membrane which regulates the movement of proteins and RNA in and out of the nucleus.</span>
Answer:
Option A
Explanation:
Standard molar entropy determines the randomness of a mole of substance. Thus, the larger and complex a molecule is, the larger will be its molar entropy.
The molar entropy of gases is higher than liquids which is turn is higher than solid.
Here , NO2 is a gas with higher complex structure (trigonal planar) than N2 (linerar), N2O (linear) and N2O2 (linear)
Hence, NO2(g) will have greatest standard molar entropy
Option A is correct
