Response is below
Explanation:
The different types of mining are underground, surface, placer, and in-situ. Underground mining uses various materials to excavate resources from beneath the surface of the Earth. Surface mining is a category of mining that in which soil and rock overlying the mineral deposit are removed. Placer mining is the mining of stream bed deposits for minerals. In-situ mining is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit.
Answer:
The answer to your question is 1.2 moles
Explanation:
Reaction
N₂(g) + 3H₂ (g) ⇒ 2NH₃
Check if the reaction is balanced
Reactants Elements Products
2 N 2
6 H 6
As the number of reactants is equal to the number of products, this reaction is balanced.
Now, calculate the moles of ammonia produced using proportions
1 mol of nitrogen -------------- 2 moles of ammonia
0.6 mol of nitrogen ----------- x
x = (0.6 x 2) / 1
x = 1.2 / 1
x = 1.2 moles of ammonia are formed
Answer:
Covalent bonds involve the sharing of electron pairs between atoms. Electron pairs shared between atoms of equal or very similar electronegativity constitute a nonpolar covalent bond (e.g., H–H or C–H), while electrons shared between atoms of unequal electronegativity constitute a polar covalent bond (e.g., H–O).
Explanation:
<span>The
surface of a mirror is smoothly and therefore the rays of light are
reflected with the same angle they hit the surface. The surface of a
piece of wood on the other hand has a lot of microscopical
imperfections and hence the rays of light are reflected in multiple
directions.</span>
It is believed that the entire solar system was born f<span>rom an early nebula.</span>
