Given the reaction below, which is the oxidized substance? Mg + Cl2 mc005-1.jpg Mg2+ + 2Clmc005-2.jpg 2CI- CI2 Mg Mg2+

Answers

Answer 1

Answer: A oxidation-reduction reaction, also known as redox reaction, is a reaction which involves transfer of electrons between species. It is a reaction where there are changes in the number of the oxidation number by gaining or losing electrons. From the reaction, the oxidized substance is magnesium. It was oxidized from an oxidation number of 0 to +2.

b. Materials that transfer energy with no resistance
d. Materials that convert thermal energy into potential energy User: ______ is/are usually the best conductor/s.
a. Metals
c. Air
b. Water
d. Minerals

Answers

Superconductors are materials that transfer energy with no resistance. Metals are usually the best conductors.

Superconductivity is a phenomenon characterized by zero electrical resistance at below critical temperatures. Metals are the best conductors because the molecules inside them are tightly packed, which allows electricity to travel efficiently.

Water is also a good conductor because of the ions and minerals in it. However, water itself is not a conductor of electricity.

The answer would be B

Using the periodic table, determine which material is most likely to be a good conductor. a.sodium
b.bromine
c.carbon
d.oxygen

Answers

The correct option is A.

The elements in the periodic table are arranged into groups and columns on the basis of their atomic number. Elements with similar number of electrons in their outermost shells fall in the same group of the periodic table. There are some properties of the elements that changes both in the periods and the groups of the periodic table and one of these is conductivity. Conductivity increases across period 3 from sodium to aluminium and then decrease to silicon. Thus, sodium is a good conductor of electricity.

Sodium is the answer
