Answer:
A. Energy is released
Explanation:
Energy is only released when chemical bonds are formed.
We see from the chemical formula itself that there is 1
mole of F2 for every 1 mole of CaF2, hence the number of moles of CaF2 is also:
moles CaF2 = 1.23 moles
The molar mass of CaF2 is 78.07 g/mol, so the mass is:
mass CaF2 = 78.07 g / mol * 1.23 mol
<span>mass CaF2 = 96.03 grams</span>
Answer:
se refiera a la energía geotérmica es una energía renovable que se obtiene mediante el aprovechamiento del calor del interior de la Tierra que se transmite a través de los cuerpos de roca caliente o conducción y convección, donde se suscitan procesos de interacción de agua subterránea y rocas.
