Is the dissolving of copper (ii) chloride in water a chemical change or a physical change why?
bija089 [108]
It would be a chemical change because the chloride water would have an effect on the copper. A way to tell if something is a chemical or physical change is that chemical change is not reversible. Physical change can be reversed. For example, water can be physically changed into ice, and it can go back into water. Hope this helps!

What would the expected temperature change be (in Fahrenheit) ida 0.5 gran sample of water released 50.1 J of heat energy? The s
Mariana [72]
<h3>Answer:</h3>

23.95 °C

<h3>Explanation:</h3>

We are given;

  • Mass of the sample is 0.5 gram
  • Quantity of heat released as 50.1 Joules
  • Specific heat capacity is 4.184 J/g°C

We are required to calculate the change in temperature;

  • Quantity of heat absorbed is given by the formula;
  • Q = mass × specific heat capacity × Change in temperature

That is, Q = mcΔT

Rearranging the formula;

ΔT = Q ÷ mc

Therefore;

ΔT = 50.1 J ÷ (0.5 g × 4.184 J/g°C)

    = 23.95 °C

Therefore, the expected change in temperature is 23.95 °C
