Answer:

An earthquake is a trembling movement of the earth's crust. These tremors are generally caused by shifts of the plates that make up the earth's surface. ... A tsunami (pronounced soo-NAHM-ee) is a series of huge waves that occur as the result of a violent underwater disturbance, such as an earthquake or volcanic eruption.

Answer:

While the earthquake is caused due to tremor or movement of the tectonic plates under the surface of the earth, a tsunami is caused when the earthquake takes place under the water. Thus, we can say that a tsunami is generated due to an earthquake. However, all the tsunamis are not caused due to earthquakes.

Answer:

A holder is a person who legally obtains the negotiable instrument, with his name entitled on it, to receive the payment from the parties liable. A holder in due course (HDC) is a person who acquires the negotiable instrument bonafide for some consideration, whose payment is still due.

Answer:

Hydrogen is placed in group I of the modern periodic table due to following reasons:-

(1) It shows outer electronic configuration similar to group I elements (i.e.1s

1

).

(2) It readily looses its electron to form H

+

 ion which resembles the electropositive character of group I elements.

(3) It shows +1 oxidation state like alkali i.e. group I elements.

(4) Hydrogen also acts as a strong reducing agent like alkali metals and also forms binary compounds with electronegative elements which resembles the group I elements.

Explanation:

Hydrogen element has placed at the top of group 1 above the alkali metals because the electronic configuration of hydrogen is similar to those of alkali metals. Since hydrogen atom is very small in size, many properties of hydrogen are different from those alkali metals. In se of the periodic table, however, hydrogen is not placed in any group.

HYDROGEN IS TREATED AS A VERY SPECIAL ELEMENT AND PLACED ALONG AT THE HEAD OF THE PERIODIC TABLE.

Answer:

Pyrometallurgical treatment may produce products able to be sold such as pure metals, or intermediate compounds or alloys, suitable as feed for further processing. Examples of elements extracted by pyrometallurgical processes include the oxides of less reactive elements like iron, copper, zinc, chromium, tin, and manganese.

Pyrometallurgical processes are generally grouped into one or more of the following categories:

calcining,

roasting,

smelting,

refining.

Most pyrometallurgical processes require energy input to sustain the temperature at which the process takes place. The energy is usually provided in the form of combustion or from electrical heat. When sufficient material is present in the feed to sustain the process temperature solely by exothermic reaction (i.e. without the addition of fuel or electrical heat), the process is said to be "autogenous". Processing of some sulfide ores exploit the exothermicity of their combustion

Roasting is an application of the pyrochemical process in metallurgy​.

• Roasting is a pyrochemical process in which the ore is heated below its melting point in the presence of oxygen or air.
• Roasting is usually done in a reverberatory furnace.
• Ex: In a reverberatory furnace, heating zinc blende with oxygen produces zinc oxide as a solid and sulfur dioxide as a gas.
• 2Zns(s) + 3O2(g) → 2ZnO(s) + 2SO2(g)
