Answer:
0.83 g
Explanation:
Step 1: Write the balanced equation
Fe + CuSO₄ ⇒ Cu + FeSO₄
Step 2: Calculate the moles corresponding to 0.75 g of Fe
The molar mass of Fe is 55.85 g/mol.

Step 3: Calculate the moles of Cu produced from 0.013 moles of Fe
The molar ratio of Fe to Cu is 1:1. The moles of Cu produced are 1/1 × 0.013 mol = 0.013 mol.
Step 4: Calculate the mass corresponding to 0.013 moles of Cu
The molar mass of Cu is 63.55 g/mol.

Answer:
I'm pretty sure that it's plate movement...
NOT MY WORDS TAKEN FROM A SOURCE!!!!
Any naturally occurring homogeneous solid that has a definite (but not fixed) chemical composition and a distinctive internal crystal structure.
Minerals are usually formed by inorganic processes.
Synthetic equivalents of various minerals, such as emeralds and diamonds, are manufactured for commercial purposes.
Although most minerals are chemical compounds, a small number (e.g., sulfur, copper, gold) are elements.
Minerals combine with each other to form rocks.
For example, granite consists of the minerals feldspar, quartz, mica, and amphibole in varying amounts.
Rocks are generally, therefore, an intergrowth of various minerals.<span> </span>

(2) Arsenic. It is an element and elements are chemically the simplest units and cannot be broken down by any chemical change.
