The property of METALS of being sonorous is CALLED sonorousness orsonority. It is due to the property of sonorousness (or sonority) that metalsare USED for making bells, and strings (wires) of musical instruments like sitar and violin. 12 Metals usually have a silver or grey colour (EXCEPT copper and GOLD).

Hello DEAR I am tanwi or Jitu and my best friend is vidhyasha no one can come in between us.




Nacl ,NA2CO3 is a salt

NAOH , H3PO4, Naco3, CA(OH)2 is a base


H2SO4 ,H2SO3 is a acid.

Hope it helps you dear

Thank you
If any help say me I am tanwi I am the best friend of Vidhyasha

Carboxylic acids in aqueous solution and liquid or MOLTEN carboxylic acidscan react with ACTIVE metals to formgaseous hydrogen and a METAL salt. Such reactions OCCUR in principle for solid carboxylic acids as WELL, but are slow if the solid acid remains dry

It may HELP u.....
if it will help u then MARK it BRAINLIEST ANSWER

Can you TELL what is PROTON SWAP

i HOPE this will HELP you

the SALT is COPPER SULPHATE

We can add a SMALL amount of CURD in milk to convert it into curd . there is a BACTERIA called as lactobaccillus which is present in curd which multiplies in milk and convert it into curd

if it is HELPFUL for you Mark me as the brainliest

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. The amount of scattering DEPENDS on the FREQUENCY of the light and DENSITY of the particles.

Hey
To see that Ammonium Chloride undergose sublimation:
1) Take a test tube which is narrow from bottom.

2 )Put some amount of NH4Cl into it and then put some cotton on thr mouth of test tube so that nothinwcan come in and also NH4 Cl goes out.
3) Now apply small amount of heat to the test tube.

You will OBSERVE that FIRSTLY the compound in tube DIRECTLY changes into GASEOUS form and then sticks to the walls of the container and solidify.

Hope it helps :))

Air isn't considered a pure substance because there is no one single CHEMICAL element ofcompound that forms air. Air is a MIXTURE of VARIOUS pure chemical substances, most of which exist in the gaseous state. There are PHYSICAL processes through which we can separate the various components of air.

Draw some blobs of ink on paper (CRAYOLA washable CHILDREN's fiber tips are perfect), roll the paper into a cylinder, and PLACE it in a WINE glass with a small amount of water. As the water creeps up the paper, the COLORS willseparate out into their components. That's chromatography in action

The position of tropic of cancer in India is not fixed but changes in a complex manner over time. The areas that lie south of Tropic of Cancer are CLOSER to equator and throughout the YEAR, they experience very high temperature on the other hand, the northern parts lie in WARM temperature ZONE.

The high pressure ALSO helps FORCE liquid and MOISTURE into the food quickly, which helps it COOK faster and also helps certain foods, like tough MEAT, get very tender very quickly.

The mechanism of acid dehydration of ethanol to YIELD ethene INVOLVES the FOLLOWING three steps:

Step 1:

Protonation of ethanol to form ethyl oxonium ion:



Step 2:

Formation of carbocation (rate determining step):



Step 3:

Elimination of a proton to form ethene:



The acid CONSUMED in step 1 is released in Step 3. After the formation of ethene, it is removed to SHIFT the equilibrium in a forward direction.

N2


N2 have TRIPLE BONDING

@SKB

METHANE is a HYDROCARBON molecule having FOUR single bond

ANSWER:

lithium chloride

Explanation:

because atomic number of lithium is 3 and atomic number of chloride is 17 to STABLE in electronic configuration lithium TRANSFER it's ONE electron to chloride then lithium atomic number is 2 and chlorine is 18

These are
1.It has a HIGH CALORIFIC value.
2.It is ECO FRIENDLY.

The REACTANTS are what you START with and the PRODUCTS are the result.In CHEMICAL reaction equation the reactants are on the left side and the products are on the RIGHT.

The law of conservation of momentum states that for two objects colliding in an isolated system, the total momentum before and after the collision is equal. This is because the momentum lost by one object is equal to the momentum gained by the other.

Conservation of momentum is derived from NEWTON's laws of motion. Newton's third law states that every action has an equal but opposite reaction; the force that one object A exerts on object B is equal but opposite to the force that object B exerts on object A. By Newton's second law, this force is equal to the PRODUCT of the mass and the ACCELERATION of the objects, so the product of the mass and acceleration of object A is equal but opposite to the product between the mass and acceleration of object B.

Acceleration is the change of velocity divided by the TIME. Time is cancelled in the equation because in a collision, the forces act within the same time frame. Thus, the product of object A's mass and change in velocity is equal but opposite to the product of object B's mass and change in velocity. Momentum is defined as the product of mass and velocity, so finally the change in object A's momentum is equal to the opposite of the change in object B's momentum. In a nonisolated system, an external force is APPLIED during the collision, changing the original equation and causing momentum to differ before and after the collision.
