Answer: The property of magnesium that is exhibited by it is DUCTILITY. The correct option is A.

Explanation:

Magnesium is a member of the alkaline earth metals. It occurs in nature, only in the combined state, as Epsom salt, dolomite and in many trioxosilicates( IV) including talc and asbestos. They have the following physical properties:

--> Appearance: they are silvery-white solids

--> Relative density: It has a relative density of 1.74

--> DUCTILITY: it's very ductile in nature

--> melting point: it has a melting point of 660°C.

--> Conductivity: They are good conductor of heat and electricity.

Furthermore, DUCTILITY is the physical property of a metal associated with the ability to be hammered thin or stretched into wire without breaking. A metal such as magnesium can therefore be coiled as a thin ribbon without fracturing due to its ductile physical properties.

A salt bridge is used to provide electrons a path to flow from the electrode of one half-cell to another. TRUE FALSE
kicyunya [14]
It is false. The salt bridge is not a path for electrons, but a path for ions to flow from one half-cell to another. It help to balance the charge between the oxidation and reduction vessels.

HELP HELP IM FAILING PLZ HELP ME
RoseWind [281]

Answer:

236 g/mol

Explanation:

This question is asking to calculate the molar mass/formula mass of calcium nitrate tetrahydrate with the chemical formula: Ca(NO3)2 · 4H20. This is done as follows:

Atomic mass of the constituent elements are as follows:

Ca = 40

N = 14

O = 16

H = 1

Hence, in Ca(NO3)2 · 4H20.

= 40 + {14 + 16(3)}2 + 4 {1(2) + 16}

= 40 + {14 + 48}2 + 4{2 + 16}

= 40 + {62}2 + 4{18}

= 40 + 124 + 72

= 236

Hence, the molar mass of Ca(NO3)2 · 4H20 is 236g/mol.
