What impact did the Spanish have on the region of South America?
vichka [17]

Answer:

The Spaniards practically went to war with the native Americans in South America, such as the Inca. They also brought diseases to South America. Diseases like smallpox.

Explanation:

Then after effectively killing off most of the native American population the Spanish continued to use South America for resources and they enslaved most of what was left of the non-Spanish and mixed populations. Francisco Pizarro took a page from Cortes' book, capturing Atahualpa, Emperor of the Inca, in 1532 and Cortes was the conquistador who defeated the Aztec Empire in what is now modern day Mexico or Central America.

How many moles of Fe2O3 will be produced from a 18.0 grams of Fe
Dennis_Churaev [7]

Answer:

The answer to your question is 0.113 moles of Fe₂O₃

Explanation:

Data

moles of Fe₂O₃ = ?

mass of Fe₂O₃ = 18 grams

Process

1.- Calculate the molar mass of Fe₂O₃

Fe₂O₃ = (56 x 2) + (16 x 3)

          = 112 + 48

          = 160 g

2.- Use proportions to solve this problem. The molar mass is equivalent to 1 mol.

                   160 g of Fe₂O₃ --------------- 1 mol

                     18 g of Fe₂O₃ ---------------- x

                            x = (18 x 1)/160

                           x = 0.113 moles of Fe₂O₃
