Only bromine and mercury are liquid elements when the temperature is 25 degrees Celsius. Mercury is the sole element in the context of the question that is a liquid at 25 degrees Celsius.
The water must have flowed in and made the cell swell because the cell was hypertonic to the water (had a larger concentration of salts or other dissolved substances). The cell was in a hypotonic environment because the water is hypotonic to the cell in this case.
Sp2 hybridization permits the creation of a single double bond (flat, triangular formation). Sp3 only permits single bonds, whereas Sp permits triple bonds. There is no hybridization in S2.
Any positive integer value can be used as the principal quantum number. The value of the angular quantum number can range from to (n-1). The magnetic quantum number can range from -l to +l in value. Because the magnetic quantum number is greater than the angular quantum number, the set of quantum numbers n = 2, l = 1, ml = 2, and s = -1⁄2 cannot exist.
A compound's mole fraction is expressed as (moles of the specified compound) / (total moles of system). There are five total moles in the system and two moles of NaOH in this question. This results in the mole fraction being written as 2/5, or.40.
The propensity of an atom to draw electrons into a covalent connection is known as electronegativity. In general, electronegativity rises as one moves up groups and through periods. The elements in the periodic table's upper right corner are the most electronegative as a result. The most electronegative element on the periodic table, oxygen, is the only one in the question's context.
Higher energy reactants always move to lower energy products in a spontaneous process. As a result, there is a negative energy differential between the reactants and the products. Therefore, a decrease in Gibbs free energy ensures a spontaneous response that moves ahead.
A pair of two molecules that differ only in the presence of a proton is referred to as a conjugate acid/base pair. The base of a conjugate acid has an extra proton added to it. The acid with one fewer proton is known as the conjugate base. The species with one fewer proton, HS-, is the conjugate base of
A transition from a liquid to a gas is called vaporization. Phase transition from gas to solid is called deposition. A phase change is not described by effervescence. A transition from a solid to a liquid phase is fusion. As a result, sublimation must involve a transition from solid to gas.
The assertion is true. Electrical current can induce a non-spontaneous reaction to proceed, which is known as electrolysis.
Atomic radius grows down a group and decreases over a period. The first group's elements will be the biggest throughout that time. The element with the greatest atomic number, which is at the bottom of the list, will have the largest atomic radius. As a result, of the elements listed, rubidium has the biggest atomic radius.
