Answer:

hydrogen GAS is released

Explanation:

its BURNS off with a pop SOUND

hey mate here is the answer

Covalent radius is half of the internuclear SEPARATION between the nuclei of two single-bonded ATOMS of the same species (homonuclear). While van der Waals radius is USED to define half of the distance between the closest approach of two non-bonded atoms of a given element.

hope it helps you

mark it as BRAINLIST

ANSWER:

heyyaa mate..

here is ur answer ..

POLYATOMIC ION consist of more than one atom. The atom in that is usually covalenty bounded to one other

Answer:

MEDICINES which are basically in nature is USE to CURE acidity

Explanation:

acidity is cause when their is excessive amount of acid is PRODUCED in STOMACH

Answer:

A REACTION will takes place.And SALT will be formed along with water.

like this..

HCL +NaOH -----> NaCl +H2O

hope it HELPS.....

When Sulphur BURNS in the presence of oxygen , it REACTS with oxygen and forms a Sulphur dioxide Which is ACIDIC in NATURE. ... That Acidic compound is Sulphuric acid(H2SO4).

ANSWER:

no it is a acid

Explanation:

it TURNS RED LITMUS to BLUE

CHINA ROSE as Indicator

ADD some WARM water. ... Use the coloured water as an indicator. Add five drops of the indicator to each of the solutions. A solution of china rose turns GREEN in a basic solution, and bright pink or magenta in an acidic solution.

The oxides of nitrogen and sulfur are present in the air or atmosphere. When RAIN falls then nitrogen oxide and sulfur oxide dissolve in rain WATER.

Since these oxides are acidic in nature and when they dissolve in rain water then the rain water ALSO becomes highly acidic in nature.

Therefore, due to this reason PH of acid rain is sometimes as low as 2.

Answer:

A molecular orbital (MO) can be used to represent the regions in a MOLECULE where an electron occupying that orbital is likely to be FOUND. Molecular orbitals are obtained from the combination of atomic orbitals, which PREDICT the location of an electron in an ATOM.

AIR , EXHAUST from chimneys, COTTON , water , CHALK, iron

ACID-FREE standard solutions (0.05 M) of the perchlorates of the divalent metals copper, nickel, cobalt, iron, zinc and manganese suitable for use in the determination of stability constants of chelates by the potentiometric method can be prepared utilizing an ion-exchange technique. A column 1.6 cm. diameter containing 50 ML. ‘Amberlite’ cation exchange resin IR 120(H) is treated with a solution (0.1 M) of the pure SULPHATE or chloride of the divalent metal until the pH's of the entrant and issuing solutions are identical. After eluting the excess metal salt solution with water the metal ions bound to the resin are displaced by passing a pure solution of barium perchlorate (0.052 M) on to the resin. Since barium ions have a stronger affinity for the resin than the divalent ions of copper, nickel, cobalt, iron, zinc and manganese, the latter are displaced and the barium-free fractions of the eluates contain the pure perchlorate solutions of these metals.

Answer:

Gold Number is a term USED in colloidal CHEMISTRY. It is defined as the minimum amount of PROTECTIVE colloid in milligrams which PREVENTS a color change from red to violet of 10ml gold sol by the addition of 1 ml of 10%NaCl solution.

Explanation:

mark me and follow me

Answer:

colloid is a solution that has particles ranging between 1 to 1000 nanometres , yet are still able to remain evenly distributed throughout the solution. ... in SIMPLE WAY , cheese is a solid EMULSION in which liquid is solute and solid is SOLVENT. hence, cheese is colloidal solution of liquid in solid

hope these will help you....

PLEASE mark as brainliest.....

CHEESE IS A COLLOIDAL SOLUTION OF LIQUID IN SOLID.....

EXPLANATION :

colloid is a solution that has particles ranging between 1 to 1000 nanometres , yet are still able to remain EVENLY DISTRIBUTED throughout the solution. ... in SIMPLE way , cheese is a solid emulsion in which liquid is SOLUTE and solid is solvent. hence, cheese is colloidal solution of liquid in solid..........

#ANSWER WITH QUALITY.....

Answer:

The COLLOIDAL state matter is the state in which the size of the particles lies in between 1NM (10-9m or 104) and 1000nm (10-6) and the systems CONSISTING of dispersed particles in this RANGE are CALLED colloidal systems.

ANSWER:

SODIUM CHLORIDE, CARBON dioxide

Explanation:

A liquid is a nearly incompressible fluid that conforms to the SHAPE of its container but retains a constant volume independent of PRESSURE. As such, it is one of the four fundamental STATES of matter, and is the only state with a definite volume but no fixed shape.

Explanation:

A SIMILARITY between all the material is that all the materials are made up of matter, they all OCCUPY space and have mass. The BRAINLIEST Answer! Yes there is similarity between materials the similarity is they all are made up of matter and they all have a state like LIQUID, gas or SOLID..

ANSWER:

• The Tyndall effect is the scattering of light as a light beam passes through a colloid.

• The INDIVIDUAL suspension particles SCATTER and reflect light, making the beam VISIBLE.

• As with Rayleigh scattering, blue light is SCATTERED more strongly than red light by the Tyndall effect.

Answer:

When hydrogen gas combines with nitrogen to form Ammonia the following chemical REACTION will take place. Our equilibrium reaction will be N2(g) + 3H2(g) ⇔ 2NH3(g) + HEAT. In this CASE, Hydrogen and nitrogen react together to form ammonia.so this is combination reaction.

• When we bring a charged body in CONTACT with the EARTH, all the excess charge on the body disappears by causing a momentary current to pass to the ground through the connecting conductor (such as our body). This PROCESS of sharing the charges with the earth is called GROUNDING or EARTHING.

Metals contain free electrons. When potential DIFFERENCE is applied at the ENDS of a metal rod, the electrons respond to it and start moving towards the positive terminal,of battery. This FLOW electrons result in the conduction of electricity through the metal.

Required materials:

• battery

• WIRE

• bulb

• a metal (iron pin)

process:

✔ connect the one end of the wire to the battery and the another end to the bulb.

✔connect the iron pin to bulb and the battery

✔ now we can see the bulb start to glow

→This shows that metals are good conductors of electricity.

Explanation:

1. basic oxide REACT with WATER to give a BASE
2. acidic oxide react with base to give SALT and water
3. Amphoteric oxide react with both the acids and BASES to give salt and water

Explanation:The clinical thermometer is used to measure BODY temperature, however, laboratory thermometer is not used for the purpose of measuring body temperature. The temperature range of clinical THERMOMETERS is 35°C to 42°C and that of laboratory thermometers is -10°C to 110°C.

SIMILARITIES Both thermometers are used to measure temperature and both of them use MERCURY.

CARBON DIOXIDE is the ANSWER

ong>ANSWER:

A GIVEN LIQUID will evaporate more quickly when it is heated. This is because the heating process results in a GREATER fraction of the liquid's molecules having the necessary kinetic energy to escape the SURFACE of the liquid.
