pls answer this ​

Answer 1

Answer:

Most students breathe a sigh of relief when the professor outlines a multiple choice exam on the syllabus, but what about the dreaded long answer exam? When this style of exam is announced it is often met with panic and concern from students, because they know they will have to demonstrate a deep understanding of the material. As I progressed further in my university career, multiple choice tests became a rarity and I quickly had to learn how to prepare for the new expectations that came along with long answer style tests. Through my experiences and some additional advice from learning professionals, I have some tips for successfully writing long answer tests.

Bloom’s Taxonomy and Long Answer Tests

Before we get into my tips for success on long answer tests, let’s take a look at the kind of skills you’ll need for this type of test.

Bloom’s (revised) Taxonomy is something we reference often in the Centre for Student Success, as it helps students understand the skills they’ll need for effective learning.

Answer 2

Answer:

The correct answer is:-

oxides- bauxite, haematite

sulphides- zinc blende,cinnabar

Explanation:

Oxide ore:-

An oxide ore is the one in which desired elements are combined with oxygen.

Oxide ore is an ore which contains metals in oxidized forms. In other terms, oxide ore is a mineral (from which a metal can be extracted) in which the elements combine with oxygen to form oxides.

Bauxite is the ore of aluminium which contains alumina in oxide form.

Unlike sulphide ores oxide ores much more energy for melting. Fir this reason hydrometallurgical approach is generally used to refine these ores.

Sulphide ores:-

Any member of a group of compounds of sulfur with one or more metals.

They are very economic and are easy to extract from the rocks.

examples

Galena- ore of lead Formula is PbS

Cinnabar-ore of mercury Formula is HgS

Copper pyrites-ore of copper.
