#BEBRAINLY

first, use a magnet for separating iron fillings, then mix the REMAINS 2 compounds in distilled WATER.

after this, filter it. residue on filter paper will be SULPHUR. by evaporating the water, the residue in the beaker will be pure Salt

a is strongly acidic as it has more TENDENCY to GIVE H+ THEREFORE more acidic and c is neutral

ANSWER:

the answer is SEVENTY EIGHT

First the lighter substance distills first and after that the heavier substance starts to EVAPORATE. Eg, with oil and water, the water distills first and after that goes into the condensation tube where it becomes sterilized. After a few MINUTES, the oil will start to evaporate but by this time the water is already cooled down and STORED safely.

Answer:

NaAL

Explanation:

• The Ionisation energy of My will be larger than of Na DUE to fully filled configuration (3s)2
• the ionisation of Al will be smaller than that of Mg due to one electron extra than the stable configuration . But smaller than Si due to INCREASE in effective nuclear charge of Si
• =NaAl

Answer:

And proteolysis is a specific cleavage of the peptide bond with the help of a SPECIAL protein, an enzyme called a protease. So unlike acid HYDROLYSIS, proteolytic cleavage is a specific process. ... Trypsin only cleaves on the carboxyl side of basic amino ACIDS, LIKE arginine and LYSINE.

Explanation:

Acids And Bases

Acids:

An acid is a SUBSTANCE that gives hydrogen ion H+or a hydronium ion H3O+when dissolved in water. A substance, which has an acidic nature, contains one or more hydrogen and an anionic group in its formula.

Example: H2SO4 (sulfuric acid) contains TWO hydrogens or hydrogen ion 2H+and sulfate anion

When sulfuric acid DISSOLVES in water it PRODUCES Hydrogen ion or hydronium ion which is shown below

Base:

A Base is a substance which gives hydroxide ion OH-when dissolved in water.

Example

NaOH It is a base since it contains OH- ion or hydroxide ion.

I FEEL very BAD about NATURE

Answer:

Evaporation is the process of a SUBSTANCE in a liquid state CHANGING to a gaseous state DUE to an increase in temperature and/or pressure.Evaporation is a fundamental PART of the water cycle and is constantly occurring throughout nature.

Explanation:

FACTORS _There are many factors that affect theevaporation rate. The rate of evaporation depends on the liquid's exposed surface area (faster when increased), the HUMIDITY of surroundings (slower when increased), the presence of wind (faster when increased) and the temperature (faster when increased).

LATENT HEAT _Latent heat of vaporization: The "amount of heat" needed to convert "unit mass of liquid" into its "vapour state" without change in its temperature is known as "latent heat of vaporization". Example: The "latent heat of vaporization" of water is "540

Answer:

The industries that produce metals, wood and paper products, chemicals, gasoline and oils, and those invaluable grabber utensils you USE to get your ring (which also needed water to manufacture) out of the garbage disposal are major users of water.Probably every manufactured product uses water during some part of the production process. Industrial water use includes water used for such purposes as fabricating, processing, WASHING, diluting, cooling, or transporting a product; incorporating water into a product; or for sanitation needs within the manufacturing facility. Some industries that use large amounts of water produce such commodities as food, paper, chemicals, refined petroleum, or primary metals.

Industrial Water Use in the United States:

Every five YEARS, water withdrawal and use data at the county level are COMPILED into a national water-use data system, and state-level data are published in a national CIRCULAR.

Answer:

The difference between evaporation and boiling are :

1. Evaporation takes place at all temperatures, while boiling OCCURS at a PARTICULAR temperature.

2. Evaporation takes place from the surface, whereas the entire liquid boils.

3. Evaporation can occur using the internal ENERGY of the system, while boiling requires an external source of heat.

4. Evaporation produces cooling but boiling does not.

5. Evaporation is a SLOW process while boiling is a rapid process.

Answer:

The electropositive CHARACTER increases as we move down the group from Li to Cs. Due to their strong electropositive nature, they emit electrons when exposed to light. ... By losing one electron, these ALKALI metals form a unipositive ion that has a noble GAS configuration

Answer:

We first need to obtain some ice. Sit the ice in a BOWL at room temperature till than it is starting to melt. Then In a freezer, ice is kept at a temperature well below freezing.  We need to allow the ice to sit outside the freezer long enough that is warms up to freezing .  The ice can't get warmer than freezing; once it reaches freezing it will START to melt.

Add 200 to 250 mL of warm tap water (40o C  or less so that there isn't too big of a temperature difference between the water and air) to the styrofoam cup. .  Measure and record the temperature of the warm water just before you are ready to add some ice.  Add one or two ice cubes (or about 1/4 cup of crushed ice) to the warm water and stir GENTLY with the thermometer until the ice is completely melted.  Try to be sure you just add ice and none of the water in the bowl from the melted ice.   You will need to use less ice or more water or both.  Use the graduated CYLINDER to measure the new volume of the water in the styrofoam cup.  This new volume will be larger than the initial volume because it contains the water from the melted ice.  The difference in the starting and ending water volumes is the mass of the ice that was melted.  Do repeat the experiment once or more time by using a different amount of water, a different amount of ice, and PERHAPS a different initial water temperature.

ANSWER:

DIAMOND is the HARDEST non METAL SUBSTANCE

FIRSTLY there are only 7 strong acids which are

1. HCL - hydrochloric ACID

2. HNO3 - nitric acid

3. H2SO4 - sulfuric acid (HSO4- is a WEAK acid)

4. HBr - hydrobromic acid

5. HI - hydroiodic acid

6. HClO4 - perchloric acid

7. HClO3 - chloric acid

Nonmetals (including – to a limited EXTENT – xenon and probably RADON) usually exist as ANIONS or oxyanions in aqueous solution; they generally form ionic or COVALENT compounds when combined with METALS (unlike metals, which mostly form alloys with other metals)

Answer:

Explanation:

Diffusion in solid is minimum or least because the movement of PARTICLES is very least and they have minimum kinetic energy so the cant move from ONE POINT to another point and they don't diffuse readily in other matter. But liquid SHOW bit more diffusionability because of more kinetic energy then solid. But gaseous has more kinetic energy AMONG all the 3 basic states of matters so they have high level of Diffusionability.

ANSWER:

FeO=4 and Fe2O3=3

Explanation:

LET FE in FeO=x

let Fe in Fe2O3=1-x

Then

Fe + 1/2O2 -> FeO

2Fe + 3/2O2 -> Fe2O3

As

x/24 + 3/4(1-x)=0.65

x=0.4 MOLE FeO

1-x/2=0.3 mole Fe2O3

0.4/0.3=4/3

Explanation:

All substances have DISTINCT physical and chemical properties, and may undergo physical or chemical CHANGES. Physical properties, such as hardness and boiling point, and physical changes, such as melting or freezing, do not INVOLVE a change in the composition of matter.

ANSWER:

You can USE GOOGLE for this .

When a chemical reaction takes place any of these changes can be observed:

★ Change in color.

★ Change in state.

★ Evolution of gas.

★ Change in temperature.

★ Formation of precipitate.

Example:

★ When LEAD nitrate and potassium iodide reacts, a yellow precipitate i.e. lead iodide is formed.

★ When sodium reacts with water, sodium HYDROXIDE is formed along with the evolution of hydrogen gas.

★ When GREEN crystals of  iron oxide is heated, a successive color change is observed from green to colorless to reddish brown along with sulphur dioxide and sulphur trioxide.

★ When quicklime is mixed with water, its FORMS slaked LIME and heat is evoluted and hence there is change in temperature.

Answer:

burning of wood is a chemical CHANGE

it turns into ASH and c02 is formed

burning of dry ICE is physical change

it just turns into WATER
