Answer:

  • The process of "slaking" of lime refers to the use of excess water for hydration. balanced equation: CaO + H₂0 = Ca(OH)₂ + heat released

  • First lets know which oxide is quick lime - CaO, is basic in nature as a result it combines with acidic oxides using heat. For example we are gonna make it react with silicon dioxide which is a very weak acid: CaO + SiO₂ → CaSiO₃

Hope this helps ~

Calculate the mean kinetic energy {e1rans) in joules of the following molecules at 350 k: (a) he, (b) co2, and (c) uf6. explain
Lady bird [3.3K]

The mean kinetic energy per molecule is , where  is the Boltzmann constant and T is the absolute temperature.

So at 1000°C, the T = 1273.15 K, kB=1.38 × 10-23, therefore the mean kinetic energy is 2.635 × 10⁻²⁰J.

<h3><u>What is Kinetic energy ?</u></h3>

The energy an item has as a result of motion is known as kinetic energy.

A force must be applied to an item in order to accelerate it. We must put forth effort in order to apply a force. After the job is finished, energy is transferred to the item, which then moves at a new, constant speed. Kinetic energy is the type of energy that is transmitted and is dependent on the mass and speed attained.

Kinetic energy may be converted into other types of energy and transported between things. A flying squirrel may run into a chipmunk that is standing still, for instance. Some of the squirrel's original kinetic energy may have been transferred to the chipmunk or changed into another kind of energy after the impact.
