Help me guys question:- 1) state whether fire is a matter or not . justify your answer ​

Answer»

is anything that has MASS and occupies SPACE. The flame itself is a mixture of gases (VAPORIZED fuel, oxygen, carbon dioxide, carbon MONOXIDE, water vapor, and many other things) and so is matter. The light produced by the flame is energy, not matter. The heat produced is also energy, not matter.

What is covalent bond?​

Answer»

SOACH RHE HO AAJ AAPKA UTUBE CHANNEL SUBSCRIBE KAR DOxDKiya Kiya jae??GOOD NIGHTHORROR DREAMS ☺️TCHERE'S UR ANS ⬇️A covalent BOND is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or BONDING pairs, and the stable balance of ATTRACTIVE and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

Define the following with examples (a)chemical bond (b)Lewis symbol or dot structure (c)octet rule​

Answer»

emical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic FORCE of attraction between oppositely charged ions as in ionic BONDS or through the sharing of electrons as in covalent bonds.b. LEWIS symbols (also known as Lewis DOT diagrams or electron dot diagrams) are diagrams that represent the valence electrons of an atom. Lewis STRUCTURES (also known as Lewis dot structures or electron dot structures) are diagrams that represent the valence electrons of atoms within a molecule.c. The octet rule is a chemical rule of thumb that reflects the theory that main group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.

Why first period in the morden periodictable contain only two elements​

Answer»

There are only two ELEMENTS in the first period: hydrogen and helium. ... This is because in QUANTUM physics, this period fills up the 1s orbital. Period 1 elements follows the duet rule, they only need two electrons to complete their valence shell. These elements can only hold two electrons, both in the 1s orbital.Explanation:I hope it will help you have a nice DAY ahead

State two characteristic features of carbon which when put together give rise to large number of Carbon compounds.[1]​

Answer»

properties of carbon which LEAD to the huge number of carbon compounds we see around us are Catenation and Tetravalence.Catenation :Catenation can be defined as the bonding of carbon atom in the " same element " in a PARTICULAR seriesTetravalency :In tetravalency, as NAME indicate that tetra means four. Four electron PRESENT in outer shell of orbit.Due to this carbon neither lose nor gain electrons to complete it's octect. Thats why carbon shares it electrons.So, it have the ABILITY to bond with another 4 atoms.
