It is called exothermic reaction because it releases heat and light and it is called combustion reaction because it is reacting and is being oxidised by O2 to MgO.
It can also be called as oxidation reaction since Mg is oxidised to MgO.
The equation presented above is that of uranium reacting with fluorine forming uranium fluoride.
The chemical reaction can be balanced by carefully studying the equation and balancing the number of atoms of each of the element in both sides of the chemical reaction. That is,
<em> U(s) + 3F₂(g) --> UF₆(g)</em>
A grey coloured rock with amphibole and intermediate plagioclase like an andesine would classify as an intermediate rock by Bowen's Reaction Series and by the classification of igneous rocks would probably be like a diorite which is intermediate between a gabbro and a granite. A diorite essentially has no quartz but has the silicates amphibole (like hornblende), mica perhaps a little pyroxene and andesine plagioclase.
Answer:
An autotroph absorbs sunlight from their stoma and converts this solar energy to chemical energy with their chloroplasts. As you can see, the sun's interaction of matter and energy is vital to sustaining all living things on Earth.
Explanation:
1 grams F2 to mol = 0.02632 mol
10 grams F2 to mol = 0.26318 mol
20 grams F2 to mol = 0.52636 mol
30 grams F2 to mol = 0.78954 mol
40 grams F2 to mol = 1.05272 mol
50 grams F2 to mol = 1.3159 mol
100 grams F2 to mol = 2.6318 mol
200 grams F2 to mol = 5.2636 mol
