Answer : 5100 KJ
Explanation : In the given reaction of
we can see that 2 moles of Al is producing -850 KJ of energy
so for 12 moles of Al we can calculate as;
12 moles of Al X
= -
5100 KJ
So, we can say that 12 moles of Al will need -5100 KJ of energy.
Some metalloids, such as silicon and germanium, can act as electrical conductors under the right conditions, thus they are called semiconductors<span>. Silicon, for example, appears lustrous but is not malleable or </span>ductile<span> (it is </span>brittle<span> - a characteristic of some nonmetals).</span>
The answer is false because qualitative data is describing something with words and quantitative data is describing something with numbers.
