Most RADICALS are reasonably stable only at very low concentrations in INERT media or in a vacuum. A NOTABLE example of a free radical is the hydroxyl radical (HO•), a MOLECULE that is one hydrogen atom short of a water molecule and thus has one bond "DANGLING" from the oxygen.

Some EXAMPLES of single replacement reactions WOULD includeZn+H2SO4→ZnSO4+H2Zinc metal reacting in SULFURIC acid to release hydrogen gas.2KBr+Cl2→2KCl+Br2The reaction between potassium bromide and chlorine gas.In both examples the reaction follows the BASIC concept of :-)AB + C ==> AC + B

It is a PROCESS by which the light TRAVELS through the colloidal SOLUTION and makes a tyndall effectExplanation:Take a BEAKER of colloidal solution and pass a light. You can observe the tyndall or brownian movement

because of the HELIUM gas inside the BALLOON and when balloon rise in the air When a balloon GOES up higher in the air, its size will increase. Since there's less air in the UPPER atmosphere, there's less stuff PUSHING back on the balloon, and hence the pressure is lower, which allows the balloon to expand.hope this will help you

tion:In chemistry, electronegativity is a measure of how strongly an atom ATTRACTS the electrons in a BOND. An atom with high electronegativity attracts electrons strongly, while an atom with low electronegativity attracts them weakly. Electronegativity values are used to predict how different atoms will behave when bonded to each other, MAKING this an important SKILL in basic chemistry.understand electronegativity, it's important first to understand what a "bond" is. Any two atoms in a molecule that are "connected" to each other on a molecular diagram are said to have a bond between them. This means essentially that they share a set of two electrons — each atom contributes one atom to the bond.The exact reasons for why atoms share electrons and bond are a LITTLE beyond the scope of this article. If you want to learn more, try this article on the bond basics or WikiHow's own How to Study the Nature of the Chemical Bond (Chemistry).Understand that chemical bonds occur when atoms share electrons.

SiO2 is in giant molecular STRUCTURE but Co2 is SIMPLE molecular structure. Because of this SiO2 is solid and Co2 is GAS at ROOM temperature.Hope it HELPS you!

URINE IS CORRECT ANSWER.......I HOPE HELP YOU.....THANKS.......

Due to INERT pair effect Tl+1 are more STABLE than Tl+3 . hence Tl+3 salts are better OXIDIZING agentHope you like my answer FOLLOW mePlease mark as brainlist

Metals are TYPICALLY malleable and ductile, DEFORMING under stress without cleaving. The NONDIRECTIONAL nature of metallic bonding is thought to CONTRIBUTE significantly to the DUCTILITY of most metallic solids.

it is a DOUBLE DISPLACEMENT reactionExplanation:2NaOH +2CuSo4=2CuOH+2NaSo4

Thomson's model of atom is composed of electron SURROUNDED by a SUPER positive charge to balance the ELECTRONS negative charges like NEGATIVELY charged on surrounded by POSITIVELY charged Pudding

Because of SIZE of CHLORINE and OXIDATION no.

hiExplanation:Avogadro’s law, also known as Avogadro’s principle or Avogadro’s hypothesis, is a GAS law which states that the total number of atoms/molecules of a gas (i.e. the amount of gaseous substance) is directly proportional to the volume occupied by the gas at constant temperature and pressure. Avogadro’s law is closely related to the ideal gas equation since it links temperature, pressure, volume, and amount of substance for a given gasAt constant pressure and temperature, Avogadro’s law can be expressed via the FOLLOWING formula: V ∝ N V/n = k Where V is the volume of the gas, n denotes the amount of gaseous substance (OFTEN expressed in moles), and k is a constant. When the amount of gaseous substance is increased, the corresponding increase in the volume occupied by the gas can be calculated with the help of the following formula: V1/n1 = V2/n2 ( = k, as per Avogadro’s law)

Holi is KNOWN as the festival of COLOURS. It is one of the most important FESTIVALS in India. Holi is celebrated each year with zeal and enthusiasm in the month of March by followers of the Hindu religion. Those who celebrate this festival, wait for it every year EAGERLY to play with colours and have delectable dishes.Holi is about celebrating happiness with friends and family. People forget their troubles and indulge in this festival to celebrate brotherhood. In other words, we forget our enmities and GET into the festival spirit. Holi is called the festival of colours because people play with colours and apply them to each other’s faces to get coloured in the essence of the festival.
