A microwave oven has a power rating of 850 w. If the microwave oven is turned on for 6 minutes ,how much energy will it use?state the units in your answer

Answers

Answer 1

Answer: Power is given by;

$P = (E)/(t)$

850 = $(E)/(6 * 60)$

E = 850 * 360

E = 306000

E = 306 kJ

Given the reaction below, which is the oxidized substance?Mg + Cl2—>Mg2+ + 2C1-
A)2014
B)Cl2
C)Mg
D)Mg2+

Answers

The metal loses electrons, and when it becomes Mg2+, it loses two electrons, becoming oxidized. So, the correct option is D.

What is Oxidation reaction?

Initially, the word "oxidation" was used to refer to chemical processes in which a component reacts with oxygen. An illustration of this is the oxidation of magnesium in the formation of magnesium oxide when magnesium and oxygen react.

Antoine Lavoisier used the term "oxidation" to describe the reaction of a material with oxygen. The meaning was later expanded to cover additional reactions in which electron are lost, irrespective of whether oxygen was present, after it was realised that the substance loses electrons when it is oxidised.

In the aforementioned example, the metal loses electrons; specifically, it loses two electrons as it changes from Mg+ to Mg2+, getting oxidized.

Therefore, the correct option is D

Answer:

Mg ²⁺

Explanation:

Τhe metal loses electrons and in forming Mg²⁺ ,it loses 2 electrons and hence oxidized.

Mg(s) ⇒ Mg²⁺ + 2e⁻
