H^+(aq) + OH^-(aq) ---> H2O(l)
<span>Na^+ and ClO4^- are the spectator ions.</span>
When you want to melt an ice, you only need the latent energy of fusion, <span>δhfus. We use the given value, then multiply this with the given amount to determine the amount of energy. Since the energy is per mole basis, use the molar mass of ice which is 18 g/mol. The solution is as follows:
</span>ΔH = 5.96 kJ/mol * 1 mol/18 g * 500 g
<em>ΔH = 165.56 kJ</em><span>
</span>
The answer is D)
<span>when the remains of a living thing are preserved and turned into rock
</span>
Answer:
Absolute error 
% Error 
5
Explanation:
The absolute error is the the difference in the measured value and the actual value of a quantity.
Here the actual value is 
grams
The measured value is 
grams
Absolute error
Percent error
Where AE stands for absolute error and AV stands for absolute value.
