Properties of Metal Oxides (a) Would you expect scandium oxide to be a solid, liquid, or gas at room temperature? (b) Write the balanced chemical equation for the reaction of scandium oxide with nitric acid. Write the balanced chemical equation for the reaction between copper(ll) oxide and sulfuric acid.

MATH121 Chapter 2 Notes LESSON 2.1 – Linear Equations in One Variable Example 1. 6(5x - 5) = -31(3 - x) (Multiply 6 and 5x, and 6 and -5) (Multiply -31 and 3, and -31 and –x) 30x - 30 = -93 + 31x (Get similar values on same sides) -x = -63 (Divide by -1 to get x by itself) x = 63 (One Solution!) Example 2. 3.4x + 5 = 4.4x (Subtract 3.4x from 4.4x to get the similar values on the same side) 5 = x (One solution!) Example 3. (2z - 9)/5 – (1/10) = (-13z + 12)/10 (Since each is a fraction, you can easily see the similar denomina
