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.
The answer is option C.
That is it is a heterogeneous mixture.
Heterogeneous mixture have the following properties:
1. Different components could be observed in the substance.
2. Different samples of the substance appeared to have different proportions of the components.
3.The components could be easily separated using filters and sorting.
Answer:
<h3>The answer is 1.30288 × 10³ g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 95.8mL
density = 13.6g/mL
We have
mass = 13.6 × 95.8 = 1302.88
We have the final answer as
<h3>1.30288 × 10³ g</h3>
Hope this helps you
Answer:
2.86 kJ
Explanation:
When a substance is heated and there's no phase change happening, the amount of heat (Q) necessary for the heating can be calculated by:
Q = m*c*ΔT
Where m is the mass, c is the specific heat capacity of the substance, and ΔT is the variation of temperature. So, in this case, m = 53.8 g, c = 1.05 J/g°C, and ΔT = 50.6 K. The temperature variation is the same in °C and K, so:
Q = 53.8*1.05*50.6
Q = 2858.394 J (÷1000)
Q = 2.86 kJ
The reason why it is not considered this is because the material was made in a lab, not through nature, which is what is required to be considered as a true mineral.
