Question
Write short notes on the following: Alloying.
✓

Answer

A homogenous mixture of two or more metals or a metal and a nonmetal in a definite proportion is called an alloy. The physical properties of an alloy are different from those of its constituents. Alloys are corrosion resistant. Alloy decreases the intensity of corrosion of metals.

Examples: Brass is made from copper and zinc, 90 % Copper and 10 % tin are used to make an alloy called bronze, Stainless steel is made from 74% iron, 8 % carbon and 18 % chromium.

A colourless organic liquid $X$ of molecular formula $C_2H_4O_2$ turns blue litmus to red. Another colourless organic liquid $Y$ of molecular formula $C_3H_6O$ has no action on any litmus but it is used as a nail polish remover. A yet another colourless organic liquid $Z$ of molecular formula $C_2H_6O$ has also no action on litmus but it is used in tincture of iodine.
  1. Name the liquid $X.$ To which homologous series does it belong? Give the name of another member of this homologous series.
  2. Name the liquid $Y.$ To which homologous series does it belong? Write the name of another member of this homologous series.
  3. Can you name an organic compound having the same molecular formula as liquid $Y$ but which belongs to a different homologous series? What is this homologous series?
  4. Name the liquid $Z.$ To which homologous series does it belong? Write the name of another member of this homologous series.

There are three plants A, B and C. The flowers of plant A open their petals in bright light during the day but close them when it gets dark at night. On the other hand, the flowers of plant B open their petals at night but close them during the day when there is bright light. The leaves of plant C fold up and droop when touched with fingers or any other solid object.
  1. Name the phenomenon shown by the flowers of (i) plant A, and (ii) plant B.
  2. Name one flower each which behaves like the flower of (i) plant A, and (ii) plant B.
  3. Name the phenomenon exhibited by the leaves of plant C.
  4. Name a plant whose leaves behave like those of plant C.
  5. Which plant/ plants exhibit the phenomenon based on growth movements?

Water and dissolved minerals get into the root hair of a plant by a process called A and enter the conducting tissue B. The process C helps the water and dissolved minerals to move up through the tissue B in roots and stem, and reach the leaves of a plant. In the leaves food is made by a process D. This food is then transported to all the parts of a plant through tissue E. The process of distributing food made in the leaves to all the parts of the plants is called F.
  1. What are (i) A, (ii) B, (iii) C, (iv) D, (v) E, and (vi) F?
  2. Which tissue is made up of living cells: B or E?
  3. Which tissue, B or E, contains sieve tubes?
  4. Which tissue, B or E, contains tracheids?

When an object made of metal A is kept in air for a considerable time, it loses its shine and becomes almost black due to the formation of a layer of substance B. When an object made of another metal C is kept in damp air for a considerable time, it gets covered with a green layer of substance D. Metal A is the best conductor of electricity whereas metal C is the next best conductor of electricity.
  1. What is metal A?
  2. What is metal C?
  3. Name the substance B.
  4. Name the substance D.
  5. What type of chemical can be used to remove the green layer from metal C and clean it? Why?
