Chemical change creates a new substance
Answer: It has 52 protons
Answer:
<h3>The answer is 8.40 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
![density = \frac{mass}{volume} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%20%5C%5C%20)
volume = final volume of water - initial volume of water
volume = 56.4 - 50 = 6.4 mL
We have
![density = \frac{53.78}{6.4} \\ = 8.403125](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7B53.78%7D%7B6.4%7D%20%20%5C%5C%20%20%3D%208.403125)
We have the final answer as
<h3>8.40 g/mL</h3>

Answer:
The heat of reaction is basically the energy that is being released and or absorbed when chemicals are transformed in a type of chemical reaction. However, the heat of reaction or also called reaction enthalpy is mostly or typically expressed as a molar enthalpy in kJ/mol and or as just a specific enthalpy in kJ/kg or kJ/L.
