ANSWER:

A COVALENT bond in chemistry is a chemical link between two atoms or ions in which the electron pairs are shared between them. A covalent bond may also be TERMED a molecular bond.

Explanation:

Answer:

propen = C3H6

1- butene = CH3-CH2-CH=CH2

1-penten = 3

HOMOLOGOUS SERIES = The series of carbon compounds FORMED by joining the same functional group in the place of a particular hydrogen atom on the carbon chains having sequentially increasing length is CALLED as homologus series.

you choose any ALKANE in homologous series

like. METHANE , ethane , propane ,.........

ANSWER:

what is your QUESTION BUDDY...

<P>Answer:

magine two baseballs are being thrown at you. One is traveling at 50 mph and the other at 150 mph. Even if you somehow catch that 150 mph ball, it might knock you off your feet. It will take more effort on your part to stop the 150 mph ball than the 50 mph one. So it STANDS to reason that velocity is a very important aspect of momentum. However, that's not all there is to momentum.

Now imagine two balls being thrown at you at 50 mph. One is a baseball and the other is a bowling ball. You probably aren't going to want to try to stop the bowling ball. It's going to keep traveling even after it hits you. Both balls are traveling at the same velocity, so what makes the bowling ball so much harder to stop? It's because it is heavier. It has more mass. So the other important aspect of momentum is mass.

In physics, we define momentum mathematically as the multiplication of mass and velocity as seen in this EQUATION: p = m * v

p = momentum

m = mass

v = velocity

As far as momentum's units go, we have no special symbol used just for momentum. Instead, it is SIMPLY the combination of mass's standard unit of kilograms (kg) and velocity's standard unit of meters per second (m/s). Momentum is measured in standard units of kilograms times meters per second

C. acetic acid

COMMENT and MARK me BRAINLIEST

Answer:

Deposition is the geological process in which sediments, soil and ROCKS are added to a landform or land mass. Wind, ice, water, and GRAVITY transport previously weathered surface MATERIAL, which, at the loss of enough kinetic ENERGY in the fluid, is DEPOSITED, building up layers of sediment.

MOLAR CONDUCTANCE = 1000K/M

Given , K=0.0248 ; M=0.2

M.C = 1000x0.0248/0.2

= 248/2

= 124 Scm^2mol^-1

Please MARK it as the BRAINLIEST answer.

Answer:

When HEATED, the pure 100% acid loses sulfur trioxide gas, SO 3, until a constant-boiling solution, or azeotrope, CONTAINING about 98.5% H 2SO 4 is formed at 337°C. ... When hot it is an oxidizing agent, the sulfur in it being REDUCED; sulfur dioxide gas may be released.

→The endothermic process is a TERM that describes a REACTION where the system absorbs the energy from its surrounding in the form of heat.

→The exothermic reaction is the opposite of an endothermic reaction. It releases energy by light or heat to its surrounding.

Explanation:

Endothermic Reaction

1. A reaction that the system absorbs energy from its surrounding in the form of heat.
2. The energy is absorbed from the surround into the reaction
3. Energy in the form of heat
4. Melting ICE, evaporation, cooking, GAS molecules, photosynthesis are few examples

Exothermic Reaction

1. A reaction that releases energy from the system in the form of heat.
2. The energy is released from the system to its environment.
3. Energy is released as heat, electricity, light or sound.
4. Rusting iron, settling, chemical bonds, EXPLOSIONS, nuclear fission are a few examples.

ANSWER

Disulphurous acid or pyrosulphurous acid is an OXOACID of SULPHUR with the formula

The salts of disulphurous acid are called disulphites or metabisulphites. The oxidation STATE of the sulfur atom bonded to 3 oxygen ATOMS is +5 while the oxidation number of other sulfur atom is +3.

Answer:

Let INITIAL amount = A

after 32 minutes = 75% of A COMPLETED = 0.75A

we know , formula for 1st order reaction ,

K = 2.303/t log[ initial ]/[final]

= 2.303/32 log{ A/(A - 0.75A)}

={2.303/32}× LOG4 --------(1)

for half LIFE , formula is

T½ = 2.303/K log2

put K ={2.303/32} × log4

T½ = 2.303/[{2.303/32} × log4 ] × log2

= 32 log2/log4

= 32log2/2log2

= 16 min

hence, half life of given reaction is 16 minutes .
