Description

Formic Acid is a reagent comprised of the organic chemical formic acid that cleaves proteins into peptides at the C- or N-terminal side of an aspartate residue.

NCI Thesaurus (NCIT)

Formic acid appears as a colorless liquid with a pungent odor. Flash point 156°F. Density 10.2 lb / gal. Corrosive to metals and tissue.

CAMEO Chemicals

Formic acid is the simplest carboxylic acid, containing a single carbon. Occurs NATURALLY in various sources including the venom of bee and ant stings, and is a useful organic synthetic reagent. Principally used as a preservative and antibacterial AGENT in livestock feed. Induces severe METABOLIC acidosis and ocular injury in human subjects. It has a role as an antibacterial agent, a protic solvent, a metabolite, a solvent and an astringent. It is a conjugate acid of a formate.

Answer:

Let us SAY we have one glass of water and after that when we ADD one or two spoon of SALT then we notice that salt dissolves in it but when we measure the water level we found that there is no difference between initial reading and FINAL reading. So what's happening over there? Why water level doesn't changed when salt is ADDED ?

Answer:

Define the following terms.

1. ACIDIC substances

2. Basic substances

3. Organic acids

4. Dilute acid

5. Concentrated acid

6. Indicators

7. Water of crystallization

8. Anhydrous salts

ANSWER:

1. Acidic Substances are the substances which contain an acid. They are the sour-tasting chemicals which are SOLUBLE in water and corrosive by nature.

2. Basic substances are the substances which contain a base. Basic substances are the bitter-tasting chemicals which may or may not be soluble in water and are soapy to touch.

3. Organic Acids are the substances with acidic properties that occur NATURALLY in plants and animals.

4. Dilute acids are the acids which contain more amounts of water and LESS amounts of acid.

5. Concentrated acids are the acids which contain more amounts of acid and less amount of water.

6. Indicators are substances that CHANGE colour in the presence of an acid or a base.

7. The water molecules present in the salt crystals which gives the crystal its shape is called water of crystallization.

8. Hydrated salts which lose their water of crystallization on heating and change into a powdery substance are called anhydrous salts.

If handles of electric TOOLS don't have any cover, electricity can transfer from tools to the body and ELECTRICIAN and can give him SHOCK. THEREFORE, handles of the tools USED by electricians usually have insulator (plastic/rubber) covers on them so as to stop electricity from getting conducted into electrician's body.

ANSWER:

From the expression of heat (q),

WHER,
c= MOLAR heat capacity
m= mass of substance

= CHANGE in temperature
Substituting the values in the expression of q:

q=1066.7J
q=1.07 kJ

Caste-based trade among the Nakarattars of Tamil Nadu This is not to SAY that the Nakarattar banking system resembled an economist’s model of Western-style banking systems … the Nakarattars loaned and deposited money with one another in caste-defined social relationships based on business territory, residential location, descent, marriage, and common CULT membership. Unlike in modern Western banking systems, it was the reputation, decisions, and reserve deposits shared among exchange spheres defined according to these PRINCIPLES, and not a government-controlled central bank, that … assured public confidence in individual Nakarattars as representatives of the caste as a whole. In other words, the Nakarattar banking system was a caste-based banking system. Individual Nakarattars organised their lives around participation in and management of various communal institutions ADAPTED to the task of accumulating and distributing reserves of capital. Source: Rudner

Read the extracts from Caste and Capitalism in Colonial India(Rudner 1994) in the box and answer the following questions.

1.What are the significant differences between the Nakarattar bankingsystem and the modern Western banking system, according to the author?

2.What are the different ways in which Nakarattar trading andbanking activities are linked to other social structures?

3.Can you think of examples within the modern capitalist economy whereeconomic activities are similarly ‘EMBEDDED’ in social structures?
