a. element b. compound c. pure substance d. homogeneous mixture e. heterogeneous mixture f. solution Matter: Any substance that is known to occupy space and has mass is matter. Matter can be classified based ...
The oxidation number of an atom in a compound or in its pure state is its charge when it becomes an ion. This is the value that is the main concern in a redox reaction. It is the one monitored because the corresponding change in this value will mean that the chemical species undergoes ...
Step 1: Label Each Compound With a Variable Label each compound (reactant or product) in the equation with a variable to represent the unknown coefficients. a CuI + b O2 = c I2 + d CuO Step 2: Create a System of Equations Create an equation for each element (Cu, I, O) where eac...
When you mix two compounds, the melting point of the compound is lowered, but the boiling point is elevated. Explain why. What are the characteristics properties of a pure substance? Is the boiling point of a substance a characteristic property? Explain. ...
