Answer:
Explanation:
Combination Reaction: is a reaction that occurs when two or more reactants combine to form a single new products. The reactants can either be Elements or Compounds. It does not require heat during the reaction.
A + B ---------> C
C (s) + O2 (g) ----------> CO2 (g)
CaO (s) + H2O (l) ---------> Ca(OH)2 (s)
In this reaction, energy is released.
Decomposition Reaction: is a reaction that occurs when a a single reactant is broken down to form two or more products. Application of heat is usually required in this type of reaction.
Δ
AB ---------> C + D
Δ
CaCO3 (s) --------> CaO (s) + CO2 (g)
In this reaction, energy is absorbed.
A It formed as softer rock broke down
Answer:
Lubrication in vehicles. When you put oil into your car or truck, you should be aware of its viscosity
Cooking. Viscosity plays a significant role in the preparation and serving of food.
Manufacturing. Manufacturing equipment requires appropriate lubrication to run smoothly.
oh, and medicine
Answer : The amount of energy released will be, -88.39 kJ
Solution :
The process involved in this problem are :
The expression used will be:
![\Delta H=[m\times c_{p,l}\times (T_{final}-T_{initial})]+m\times (-\Delta H_{fusion})+[m\times c_{p,l}\times (T_{final}-T_{initial})]](https://tex.z-dn.net/?f=%5CDelta%20H%3D%5Bm%5Ctimes%20c_%7Bp%2Cl%7D%5Ctimes%20%28T_%7Bfinal%7D-T_%7Binitial%7D%29%5D%2Bm%5Ctimes%20%28-%5CDelta%20H_%7Bfusion%7D%29%2B%5Bm%5Ctimes%20c_%7Bp%2Cl%7D%5Ctimes%20%28T_%7Bfinal%7D-T_%7Binitial%7D%29%5D)
where,
= heat available for the reaction = ?
m = mass of water = 155.0 g
= specific heat of solid water = 
= specific heat of liquid water = 
= enthalpy change for fusion = 
Molar mass of water = 18 g/mole
Now put all the given values in the above expression, we get:
![\Delta H=[155.0g\times 4.18J/g^oC\times (0-(39.0))^oC]+155.0g\times -333.89J/g+[155.0g\times 2.01J/g^oC\times (-36.5-0)^oC]](https://tex.z-dn.net/?f=%5CDelta%20H%3D%5B155.0g%5Ctimes%204.18J%2Fg%5EoC%5Ctimes%20%280-%2839.0%29%29%5EoC%5D%2B155.0g%5Ctimes%20-333.89J%2Fg%2B%5B155.0g%5Ctimes%202.01J%2Fg%5EoC%5Ctimes%20%28-36.5-0%29%5EoC%5D)
Therefore, the amount of energy released will be, -88.39 kJ
