The answer is B) pure water because pure water is a poor conductor of electricity.. thus a poor electrolyte
potassium chromate - k2cro4. ,,silver nitrate-agno3. ,, potassium nitrate-kno3 ,,Silver chromate- ag2cro4
well according to what i know....headlights only let you see about 350 feet ahead...hope it helps :)
Hi uhh i've never really typed in Spanish but here I go! :)

Answer:
Δ S = 26.2 J/K
Explanation:
The change in entropy can be calculated from the formula -
Δ S = m Cp ln ( T₂ / T₁ )
Where ,
Δ S = change in entropy
m = mass = 2.00 kg
Cp =specific heat of lead is 130 J / (kg ∙ K) .
T₂ = final temperature 10.0°C + 273 = 283 K
T₁ = initial temperature , 40.0°C + 273 = 313 K
Applying the above formula ,
The change in entropy is calculated as ,
ΔS = m Cp ln ( T₂ / T₁ ) = (2.00 )( 130 ) ln( 283 K / 313 K )
ΔS = 26.2 J/K
