What is the Wt% of SiO2 in augite?<br><br> (Ca, Fe, Mg, Na)(Mg,Fe,Al) (Si,Al)2 O6
vaieri [72.5K]

Answer:

The weight% of SiO_2 in augite is 13.16 %.

Explanation:

Atomic mass of calcium = 40 g/mol

Atomic mass of iron = 56 g/mol

Atomic mass of magnesium = 24 g/mol

Atomic mass of sodium = 23 g/mol

Atomic mass of aluminum = 27 g/mol

Atomic mass of silicon = 28 g/mol

Atomic mass of oxygen = 16 g/mol

Mass of SiO_2=28 g/mol+ 2\time 16 g/mol=60 g/mol

Molar mass of the augite (Ca, Fe, Mg, Na)(Mg,Fe,Al)(Si,Al)_2 O_6 = M

M=40 g/mol+2\times 56 g/mol+2\times 24 g/mol+23 g/mol+3\times 27 g/mol+2\times 28 g/mol+6\times 16 g/mol=456 g/mol

Weight% of SiO_2 in augite:

w\%=\frac{60 g/mol}{456 g/mol}\times 100=13.16\%

Explanation:

  • As global warming is a long rise in the average temperatures of the earth climate it's a major aspect o climate change taking place all over the world. And it is measured by the rise in rising in surface temperature both on land and in oceans and measured continuously as its growth is continuous.
  • According to the IPCC panel the the global rise in temperature form 2.8 degree to 4.8 degrees in 21st century and the possible costs associated to this event site migration of species from these place, along with the environmental impact of mass extinction or relocation natural ecosystems such as coral reefs, mountain chains and shrinking of arctic and antarctic poles.
  • Various NGOs have come up that try to mitigate this change in the evolution of natural gases, either by climatic engineering or by adaptation of habitats. NASA, UNFCCC and G77 nations have taken this step towards the prevention of climatic change.
