The diagram below shows three kettles with their powers and the time they take to boil 500cm3 of water. How much energy is trans
Bad White [126]

The energy transferred is given as the product of power and time. The 1.4 kW kettle with boiled water produces 378 kJ of energy.

<h3>What is energy?</h3>

Energy is the quantitative property that determines the work done by the body in the form of heat and light.

The image showing the kettles with time and power is attached below.

Given,

Power of the kettle = 1.4 kW

Time taken = 4.5 minutes

If power = energy ÷ time

Then, energy = power × time

= 1.4 × 0.075

= 0.105 KWh

Therefore, 0.105 kWh or 378KJ is the energy transferred.

Oksana_A [137]

Answer:

Explanation:

First, the KClO3 moles is determined by using given grams of KCl produced from the reaction.

Next, the moles of O2 produced is obtained by using the moles of KClO3 which then, finally converted into mass of O2.

Analyzing the given chemical reaction clearly shows that, 2 moles of KClO3 produces 2 moles of KCl and 3 moles of O2.

From the given grams of KCl produced the initial grams of KClO3 used in the reaction is determined as follows,
