1. *the chemical formula for lithium oxide is __.

(b) ( li_2o ) (c) ( lio_2 ) (d) ( li_2o_3 )
(ii) chloride? (d) ( fecl_3 )

Explanation:

Question #2 Solution:

Step1: Solve for \( x \) from \( 5x + 6 = 10 \)

Subtract 6 from both sides: \( 5x = 10 - 6 = 4 \)
Then divide by 5: \( x = \frac{4}{5} \)

Step2: Substitute \( x \) into \( 10x + 3 \)

Calculate \( 10x \): \( 10 \times \frac{4}{5} = 8 \)
Add 3: \( 8 + 3 = 11 \)

Answer:

c. 11
