Question
Why does distilled water not conduct
electricity?Solution
Distilled water does not conduct electricity because it lacks ionic compounds, such as salts, acids, or bases, which are necessary to facilitate the flow of electric current. In its pure form, water is a poor conductor of electricity.
- What will come in place of (?) in the given expression.
β324 + β121 β β49 = ? 1360 Γ· 8 + 490 Γ· β49 + ? = 150 Γ 2
1024 Γ· 32 = 2(1/2)Γ?
(β529 + 63 /8)% of 800 = ?% of 250
8(3/4) + 5(1/6) β 4(3/4) = ?
Evaluate: 25 β 4 Γ (3 + 2) Γ· 5
20% of 1500 β 75% of 200 = 125% of ?Β
62 of 8 - 320 Γ· 4 = ?3 + 200
540 Γ· 6 + 25 % of 120 + ? * 8 = 72 * β9
