Correct Answer: D. NaHCO₃

Correct Answer: A. bring government nearer to the people

Explanation

(a) (i) - All elements consist of atoms which are indivisible

- Atoms can neither be created nor destroyed

- The atoms of an element are all alike but differ from those / atoms of other elements

- When atoms combine with other atoms they do so in simple ratios

-All chemical changes result from the combination or separation of atoms

(ii) If A and B form more than one compound, since the atoms are indivisible, combination will be in (simple) integral ratios, as mass of atom of each element is fixed.

(b) (i) - soap

- margarine

- propan – 1,2,3 - triol / glycerine

Alkaline hydrolysis gives soap / propan-1,2,3-triol

(c)Atomic radii increases down the group and decreases across the period hence the size of Beryllium (Be) is about the same as the size of Aluminium (Al).The charge densities of Be\(^{2+}\) and Al\(^{3+}\) cause almost the same effect.

OR

Periodic properties increase / decrease from left to right and decrease / increase down the group in the periodic table. A diagonal relationship/similar properties exist between a pair of diagonally adjacent elements in the second and third periods ofthe periodic table as in the case of Be and Al.

(d) I\(_2\) + 2Na\(_2\)S\(_2\)O\(_3\) → 2NaI + Na\(_2\)S\(_4\)O\(_6\)

Correct Answer: D. rail

Correct Answer: B) Tapeworm

Explanation

This question is asking us to identify the organism that is not a micro-organism. Micro-organisms are tiny living things that can only be seen with a microscope. The options given are Virus, Tapeworm, Coccus, and Vibro cholera. Out of these options, the correct answer is Tapeworm. Tapeworms are not micro-organisms because they are relatively large parasites that can be seen with the naked eye. They live in the digestive tracts of animals, including humans, and can cause health problems. On the other hand, viruses, cocci, and Vibro cholera are micro-organisms. Viruses are tiny infectious agents that can only replicate inside living cells. Cocci are spherical bacteria that can cause diseases such as strep throat and pneumonia. Vibro cholera is a type of bacterium that causes cholera, a serious and sometimes deadly disease. In summary, Tapeworm is not a micro-organism while Virus, Coccus, and Vibro cholera are micro-organisms. It is essential to understand the characteristics and types of micro-organisms to identify and classify them correctly.

Correct Answer: C. 30

Correct Answer: D. Umrah

Correct Answer: B. ore

Explanation

The underlined vowel sound in 'pour' is /?:/ as in 'ore'. Therefore, the word that has the same vowel sound as the one represented by the underlined letter(s) in 'pour' is 'ore'.
