Answer:
Word equation: <u>Potassium chlorate → Potassium chloride + Oxygen</u>
Chemical equation: <u>KClO₃ → KCl + O₂</u>
Explanation:
<em>This is decomposition reaction so there will only be one reactant, which is potassium chlorate.</em>
The chemical equation will be:
KClO₃ → KCl + O₂
The balanced equation would be:
2KClO₃ → 2KCl + 3O₂
The word equation will be:
Potassium chlorate → Potassium chloride + Oxygen
The answer is OH.
Hope this helps!
Answer:
The pressure of the gas would be 3.06 atm
Explanation:
Amonton's law states that the pressure is directly proportional to the absolute temperature of a gas under constant volume. The equation is:
P1 / T1 = P2 / T2
<em>Where P1 is the initial pressure = 3.16atm</em>
<em>T1 is initial absolute temperature = 273.15 + 32.2°C = 305.35K</em>
<em>P2 is our incognite</em>
<em>And T2 is = 273.15 + 22.9°C = 296.05K</em>
<em />
Replacing:
3.16atm / 305.35K = P2 / 296.05K
3.06 atm = P2
<h3>The pressure of the gas would be 3.06 atm</h3>
Enthalpy change is the difference between energy used and energy gained. The change in enthalpy of the liquid mercury is 0.0231 kJ.
<h3>What is the enthalpy change?</h3>
Enthalpy change is the difference between the energy used to break chemical bonds and the energy gained by the products formed in a chemical reaction.
The enthalpy change is given by,
and,
Given,
Mass of the liquid mercury (m) = 11.0 gm
The specific heat of mercury (c) = 0.14 J per g per degree Celsius
Temperature change = 15 degrees Celsius
Enthalpy change is calculated as:
Therefore, 0.0231 kJ is the change in enthalpy.
