Answer is: <span>naturally occurring solid, inorganic compound or element is mineral.
Minerals usually have </span>crystalline form, that means than crystal constituents (atoms<span>, </span>molecules <span>or </span>ions<span>) are arranged in a highly ordered microscopic structure, forming a </span>crystal lattice<span> that extends in all directions.
</span><span>For example m</span>agnetite<span> is a </span><span>mineral of iron oxide.</span>
Sound travels most quickly through solids because _____.
answer is: because solids r the most sense.
The distance between molecules in solids r very small.Because they are so close, they can collide very quickly, i.e. it takes less time for a molecule of the solid to 'bump' into its neighbor. Solids are packed together tighter than liquids and gases, hence sound travels fastest in solids.
The equation is as follows;
2CH3OH(g) = 2CH4(g) + O2(g), ΔH= +252.8 kJ
From the equation; for the reaction to produce 2 moles of methane (32g) an energy of 252.8 kJ is released.
Therefore; for an energy of 82.3 kJ the number of moles that will be produced will be; = (2×82.3)/252.3
= 0.6524 moles
which is equivalent to 0.6524 × 16 = 10.438 g
There, the mass of CH4 produced will be 10.438 g
