36 g. of sodium chloride is dissolved in 100 g. of water at 300 Kelvin, find the concentration of mass by mass percent

Answer» MASS of Sodium CHLORIDE =36g
Mass of Water = 100g
TOTAL mass of solvent = 136g

Mass/mass %
= mass of solute /mass of solvent * 100
= 36 / 136 *100
= 26.4705%

why and when does a current carrying conductor kept in a magneu field exprence force ? list the factor on which direction of this force depend?

Answer»

Mention the factors on which the direction of force experienced by a current carrying conductor placed in a magnetic FEILD depend

a) Mention the factors on which the direction of force experienced by a current carrying conductor placed in a magnetic feild depend.
B) Under what condition is the force experienced by a current carrying conductor placed in a magnetic feild maximum?
c) A proton beam is moving along the direction of a magnetic field. What fo

 The direction of force experienced by a current carrying conductor placed in a magnetic field depends on the direction of the current in the conductor and the direction of the applied magnetic field. This is given by FLEMING's left HAND RULE


Fleming’s left hand rule



If the forefinger, middle finger and thumb of the left hand are stretched such that they are at right angles to each other, then:The forefinger gives the direction of the magnetic field.

       •  The middle finger points in the direction of the current.
       •  The thumb gives the direction of the force acting on the current-carrying conductor placed in the external magnetic field. 

(b) The force experienced by a current carrying conductor is maximum when the current and magnetic field are at right angles to each other. 

(c) Since the proton beam is moving along the magnetic field the force acting on the proton beam is zero.

State the merits of whittakers method og classification.

Answer»

The five-kingdom classification has certain drawbacks also, particularly with reference to the lower forms of life.

· The kingdoms Monera and Protista include DIVERSE, heterogeneous forms of life. In both the kingdoms there are photosynthetic (autotrophic) as WELL as non-photosynthetic (heterotrophic) organisms. Both the kingdoms include organisms which have cells with cell wall as well as without cell wall.

· None of the three higher kingdoms include a single ancestor of all its forms.

· Multicellular lines have originated from protistans several times.

· Unicellular GREEN ALGAE like Volvox and Chlamydomonas have not been included under Protista because of their resemblance to other green algae.

· Slime moulds differ totally from other members of Protista in their general organization.

· Viruses have not been given PROPER place in this system of classification

Steaming and baking are considered better cooking practices than boiling or frying.Give reasons​..

Answer»

When you fry food, the oils that you make use of are rich source of bad fats and saturated fats. These fats can ultimately lead to a number of conditions including obesity and heart related problems. The MOMENT you boil food in water it is obvious that all essential ingredients that are present in the food substances are MIXED with water and get drained at the end when draining water. This leaves the food product less nutritious in value.

Baking or steaming on the other hand does not involve MAKING use of excess amounts of oils or water to cook food. So the natural ingredients of the food are always preserved and consumed by our body. It also MAKES the food more nutritious and healthy.

How do we clean silver or brass articles that have got tarnished?

Answer»

This is a easy WAY to electrochemically clean up brass, bronze and silver items that are badly tarnished.

I have used it QUITE a bit to clean up boat hardware and items I have picked up while diving.

The method is simple, and leaves you with a nice clean item WITHOUT having to do much work.

Brass, bronze and silver tarnish because the metal reacts with compounds in the surroundings. This can be oxygen, sulfur compounds, carbon compounds or chlorides.

The tarnishing actually preserves the metal below by sealing it in, so it can not react further with the surroundings. This is the effect that protects statues, and roof cladding that are exposed to the elements for centuries. Sometimes, however, we wish to remove this tarnishing, like in the example of the bronze handle pictured here.

One way to remove tarnishing is to use abrasives like sand paper or polishing creams. Any such mechanical polishing removes some of the metal every time you do it. This can be seen on old silverware, where the patterns and engravings are usually rounded and have lost detail.

The electrochemical way of removing tarnishing, that we use here, is gentler in this respect. In SHORT terms it turns the surface metal back to its original state by removing only the compounds that reacted with it in the first place.

This is a good way to clean up DETAILED items, where mechanical polishing could cause damage. It could also save you a lot of polishing work if the metal is badly tarnished.

Information on the modern diagnostic and treatments of cancer

Answer»

Cancer can be treated by surgery, chemotherapy, radiation therapy, hormonal therapy, targeted therapy (INCLUDING immunotherapy such as monoclonal antibody therapy) and synthetic lethality. The choice of therapy depends upon the location and grade of the tumor and the stage of the disease, as well as the general state of the patient (performance status). A number of experimental cancer treatments are also under development. Under current estimates, two in five PEOPLE will have cancer at some point in their lifetime.[1]

Complete removal of the cancer without damage to the rest of the body (that is, achieving cure with near-zero adverse effects) is the ideal goal of treatment and is often the goal in practice. Sometimes this can be accomplished by surgery, but the propensity of cancers to invade adjacent tissue or to spread to distant sites by microscopic metastasis often limits its effectiveness; and chemotherapy and RADIOTHERAPY can have a negative effect on normal cells.[2] Therefore, cure with nonnegligible adverse effects may be accepted as a practical goal in some cases; and besides curative intent, practical goals of therapy can also include (1) suppressing the cancer to a subclinical state and maintaining that state for years of good quality of life (that is, treating the cancer as a chronic disease), and (2) palliative care without curative intent (for advanced-stage metastatic cancers).

Because "cancer" refers to a class of diseases,[3][4] it is unlikely that there will EVER be a single "cure for cancer" any more than there will be a single treatment for all infectious diseases.[5]Angiogenesis inhibitors were once thought to have potential as a "silver bullet" treatment applicable to many types of cancer, but this has not been the CASE in practice.[6]
