Can the element gold kick out magnesium from a compound?

Chemistry

Misha Larkins [42]1 year ago
7 0

Gold cannot replace Magnesium from a compound as gold is placed lowest in the reactivity series of metals. It won't even react with the compound let alone replace it. Gold has great ductile strength and malleability.

 Features of Reactivity Series of Metals

  • The metals at the top of the reactivity series are powerful reducing agents since they are very easily oxidized. These metals tarnish or corrode very easily though.
  • The reducing ability of the metals grows weaker while traversing down the reactivity series.
  • The electro-positivity of the elements also reduces while moving down the reactivity series of metals.
  • All metals that are found above hydrogen in the activity series liberate H2 gas upon reacting with dilute hydrochloric acid(HCl) or dilute sulphuric acid(H2SO4).
  • Metals than on the reactivity series have the ability to displace metals that are placed lower from their salt solutions such as Mg can replace Au but Au cannot replace Mg as Au is kept lowest in the reactivity series
  • Higher ranking metals require greater energy for their isolation from ores and other compounds to stay highly reactive.

Therefore Gold cannot replace Magnesium from a compound as it is the least reactive metal and therefore, comes lower than Magnesium in the reactivity series

What is the velocity of a wave with a frequency of 2.0 Hz and a wavelength of 0.4?
andrew-mc [135]
The velocity of the wave is calculated by multiplying the wavelength with the frequency. It is to be noted that the unit Hz is equal to 1/s. 

 velocity = (wavelength)(frequency)

Substituting the known values,

velocity = (0.4 m)(2/s) = 0.8 m/s

<em>Answer: 0.8 m/s</em>

3.0 L of a gas has a temperature of 78 C find the volume of the gas at standard temperature
jeka57 [31]

Answer:

= 2.33 L

Explanation:

V1/T1 = V2/T2

V1 = 3.0 L

T1 = 78 + 273

   = 351 K

At s.t.p the temperature is 273 K and pressure is 1 atm.

V2 = ?

T2 = 273 K

V2 = V1T2/T1

    = (3.0 ×273)/351

    = 2.33 L
