Sample response:


A convenience sample is used. The sample could be biased because it limits the population to listeners of that radio station at a certain time. Callers may be more likely to have a strong opinion on the issue.

Which of the following describes the relationship between elements of an ecosystem? Elements of ecosystems are mutually dependen
Margaret [11]

Elements in the ecosystems are mutually dependent on each other

Explanation:

The ecosystems are very complex. Basically, they represent a community of living organisms in conjunction with the non-living components of the environment, and all together acting a single system. All the living organisms have influence on each other, but also on the non-living components of the environment, and vice versa. This results in the system being a ''well oiled machine'', but also making it very fragile, as if one component is eliminated, everything will suffer.

  • The ecosystems are defined by multiple factors, including the latitude, climate, topography, and the living organisms themselves.
  • Everything is dependent on many other components in an ecosystem, so drastic changes often have devastating effects, resulting in extinctions.
  • The changes in the ecosystems occur because of the natural cycles, impact with space objects, or more recently because of the human activity.

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\%
