3 STEPS OF PHOTOSYNTHESIS:

1) Absorption of light energy  by chlorophyll .

2) Conversion of light energy to chemical energy,by breaking down of water molecule .

3) Reduction of carbon dioxide  by carbohydrate .

PROCESS OF DIGESTION:

It involves INGESTION,DIGESTION,ABSORPTION,ASSIMILATION AND EXCRETION.

Take in of food,after that it goes into stomach where it is broken down into smaller substances.Then the food which is not USEFUL is thrown out through LARGE intestine,the USE full and converted into energy is done small intestine.

What are the positive effects of earthquakes? ... A: Earthquakes are very useful to HUMANS because they PROVIDE a picture of what's GOING on underground. This can make OIL and gas extraction more efficient, and allows scientists to monitor the progress of WATER during geothermal energy extraction.

Answer:

A....

The ELEMENT X is Sodium (Na)

The element Y is Litium (Li)

B....

Yes these element belong to the same group that is ALKALI metals Group 1.As they all have 1 electron in its outermost shell.

C...

Sodium is more electropostive in nature as it has more electrons than Litium so its ability to loose electrons is more than that of Litium.

CATHOD RAY TUBE :The cathode-ray tube (CRT) is a vacuum tube that contains one or more ELECTRON GUNS and a phosphorescent screen and is used to display images. It modulates, accelerates, and deflects electron beam(s) onto the screen to CREATE the images.

Answer:A test light, test lamp, voltage tester, or mains tester is a piece of electronic test equipment used ... The test light is an electric lamp CONNECTED with ONE or two INSULATED wire ... This means that no direct metallic contact with the circuit is required.

Explanation:Determine whether the electricity is on or off by USING a two-prong voltage tester. Place the black lead wire on the other screw. When checking an outlet that is already attached to the wall, place the RED lead wire into the outlet and the black lead wire on the screw on the top screw of the outlet plate.

Answer:

5 differences between ionic and COVALENT bonds:

i) Ionic bond is FORMED by the transfer of electrons.

 Covalent bond is formed by the sharing of electrons.

ii) Ionic bond is present between a metal and a nonmetal.

  Covalent bond binds two nonmetals.

iii) Ionic bond forms compounds which are hard SOLIDS CONSISTING of ions.

   Covalent bond forms compounds which are gases or liquids or SOFT solids.

iv) Ionic bond forms compounds which are non-volatile with high melting and     boiling points.

   Covalent bond forms compounds which are volatile with low melting and boiling points.

v) Ionic bond example - NaCl

   Covalent bond example - HCl.

Explanation:

Radioisotopes find wide applications in the fields of medicine, agriculture, archeology, engineering, etc.

AGE of minerals and rocks

The radioactive properties of uranium-238 (92U238) are used to determine the approximate age of minerals and rocks. Uranium-238 (half-life = 4.5 109 years) disintegrates to stable lead-206 (92Pb206) isotope. The half-life of uranium-238 is longer than that of any other member in the series. Hence, all the uranium-238 disintegrated would have been converted to lead-206.

Assuming that the rock did not contain any lead initially, we can calculate the age of the rock by measuring the ratio of concentrations of 92U238 and 82Pb206. Knowing the ratio of concentrations, , the amount of uranium-238 originally present and the amount of uranium-238 present at the TIME of ANALYSIS can be calculated. From this the age of rock can be calculated by USING the equation,

Where,

No is the amount of 92U238 present initially.

N is the amount of 92U238 present after time, t.

l is disintegration constant, which is equal to

This can be better understood with the help of an example.

Example: A sample of pitchblende contains 0.5 g of lead-206 for EVERY gram of uranium-238 present in it. Calculate the age of the pitchblende ore. (half-life of uranium-238 = 4.5 109 years).

Comparison Chart

BASIS FOR COMPARISON ACIDS BASES

Arrhenius Concept Acid is the substance when dissolved in water, increases the concentration of H+ ions. The base is the substance when dissolved in water, increase the concentration of OH- ions.

Bronsted-Lowry Concept Acids are the proton donor. Bases are the proton acceptor.

Lewis Concept Such species that accepts the PAIR of electrons (an electrophile) and will have vacant orbitals are known as Lewis acid. Such species that donates the pair of the electron (a nucleophile) and will have a lone pair of electrons are known as Lewis base.

Chemical formula Such compound whose chemical formula begins with H, for EXAMPLE HCl (Hydrochloric acid), H3BO3 (Boric acid), CH2O3 (Carbonic

acid). Although CH3COOH (Acetic acid) is an exception. Such compounds whose chemical formula ends with OH, for example KOH (Potassium hydroxide), NaOH (Sodium hydroxide).

pH scale (concentration of hydrogen ions in a SOLUTION) Less than 7. Greater than 7.

Physical Characteristics Sour in taste. Bitter in taste.

Gives burning sensation. Odorless (except ammonia).

Acids are usually sticky. Bases are slippery.

Reacts with metals to produce hydrogen gas. Reacts with fats and oils.

Phenolphthalein Indicator It remains colorless. It gives pink color.

Litmus test Turns blue litmus paper to red. Turns red litmus paper to blue.

Strength Depends on the concentration of hydronium ions. Depends on the concentration of hydroxide ions.

Dissociation when mixed with water Acids dissociate to give free hydrogen ions (H+) after mixing in water. Bases dissociate to give free hydroxide ions (OH-) after mixing in water.

Examples Hydrochloric acid (HCl), Sulphuric acid (H2SO4), Nitric acid (HNO3), Carbonic acid (H2CO3). Ammonium hydroxide (NH4OH), Calcium hydroxide (Ca(OH)2), Sodium hydroxide (NaOH).

Uses Used as preservatives, fertilizers, as preservatives, used as carbonated drinks, processing leather, household cleaning, making sodas, flavor to food, etc. Used in gastric medicine (antacid), soaps, detergents, cleanser, antiperspirant armpit deodorant, non-hazardous alkali to neutralise ACIDIC wastewater, neutralise soil acidity.
