The major visible difference between<span> the two are crystal size, </span>intrusive rocks<span> have a larger crystal/grain texture due to the slow cooling of magma below the earth surface which encourages the growth of larger crystals, while </span>extrusive rocks<span>, because of the rapid cooling at/above the earth's surface does the opposite. Hope I helped</span>
I believe the answer is 50.5 molecules
In a reduction reaction,
some electrons are gained by the substance being reduced. The balanced
half-reaction to this would be:
<span>MnO2(s) + 4 H+ (aq)
+ 2e ---> Mn^2+ (aq) + 2 H2O
(aq)</span>
<span>It is called balanced reaction
since the number of each element in the left side is equal to the number of
each element on the right side.</span>
I think it's a Oxygen Difluoride
