Answer: The valency of oxygen is 2, because it needs two atoms of hydrogen to form water.

Explanation: The nearest noble gas to magnesium is neon with electronic configuration of [2,8], to achieve this stable electronic configuration Mg can lose 2 valence electrons, hence its valency is 2 + ^+ +

tester [92]

The answer is Adsorbent

The adsorbent has a high affinity for solvent and the chemical components of the mixture.

Chromatography is a method of separation in which the mixture of substances is introduced into a mobile phase (solvent). The separation occurs as the solvent interacts with an adsorbent(stationary phase).

The extent of separation of the components of the mixture depends on the extent of interaction between the mobile and the stationary phase . This interaction also determines the retention factor (Rf) of the separation.

For a definition of chromatography, see

A chemist must prepare 550.0 ml of hydrochloric acid solution with a pH of 1.60 at 25°C . He will do this in three steps: Fill a
horsena [70]

Answer:

Vol concentrated HCl needed = 1.73 ml

Explanation:

Prep 550 ml of HCl(aq) solution with pH = 1.60 at 25°C using 8M stock concentrate.

[HCl] = [H⁺] = 10⁻¹°⁶⁰M = 0.0251M HCl(aq)

Molarity Concentrate x Volume Concentrate = Molarity Dilute x Volume Dilute

8M x Vol Conc. = 0.0251M x 550ml

Vol Conc needed = 0.0251M x 550 ml / 8M = 1.73 ml of concentrate

Mixing => to the quantity of water in the mixing flask transfer 1.73 ml of the 8M HCl concentrate solution and dilute up to but not to exceed the calibration mark on the mixing flask.
