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\%

In what ways do landforms, bodies of water, and climate help determine where people live in East Asia?
wariber [46]

Answer:

<em>Generally speaking, Geography has a tremendous impact on where and how people live in a country.</em>

Explanation:

In East Asian countries such as Vietnam, Laos, Cambodia, Thailand etc, we can kind all kinds of landscapes including hilly areas and beautiful sea shores.

However the population is mostly centered in areas which are relatively flat and with a water body near by, such as a river.

A warm temperature with plenty of annual rain that supports local agriculture is also proffered by most people. Even in parts of China, most of the population lives along rivers and warm areas.

Find the distance between each pair of points<br> (-5.2, 7) and (3,- 4)
Nadusha1986 [10]

Answer:

13.72units

Explanation:

Given parameters:

   Coordinates of the two points  =  (-5.2, 7) and (3,- 4)

Unknown:

Distance between the two points = ?

Solution:

To find the distance between two points, we use the mathematical expression below;

   D = \sqrt{(x_{2}-x_{1}  )^{2} + (y_{2} - y_{1} )^{2}   }

 From the given coordinates;

        x₁  = -5.2      x₂  = 3

        y₁ = 7             y₂ = -4

Now; input the parameters and solve;

  D  = \sqrt{[3-(-5.2)]^{2} + (-4 -7)^{2}  } = \sqrt{67.24 + 121} = 13.72units

The distance between the two points is 13.72units
