The chemical composition of the magma and the rate at which it cools determine what rock forms. Igneous rocks can cool slowly beneath the surface or rapidly at the surface. These rocks are identified by their composition and texture.
Hope this help XD
Answer:
=1.4953 moles
Explanation:
Iron (III) Oxide is reduced by carbon (II) oxide into Iron. According to the following equation, One mole of Fe₂O₃ react with 3 moles of CO to produce 2 moles of Fe. Thus the reaction ratio of CO to Fe₂O₃ is 3:1
Fe₂O₃₍s₎ + 3CO → 2Fe₍s₎ + 3CO₂₍g₎
125.6 grams of CO is equivalent to: 125.6g/28.0g/mol
=4.486 moles.
The number of moles of Fe produced by the reaction is:
=(4.486 moles×1)/3
=1.4953 moles
Each state is allocated a number of electors equal to the number of its U.S. Senators
Answer:
12.
1 + 2 + 1 = 4 + 1 + 2 + 1 + 4 = 12 = 4 + 1 + 2 + 1 + 4 = 1 + 2 + 1
