Answer : Equation A represents a combination reaction, and equation B represents a combustion reaction.

Explanation :

  • Equation A : H_2+Cl_2\rightarrow 2HCl

In this reaction, hydrogen react with the chlorine to form a single product as hydrogen chloride. So, this reaction is a combination reaction.

Combination reaction : It is a type of chemical reaction in which two or more  reactants combine to produce a single product.

  • Equation B : CH_4+2O_2\rightarrow CO_2+2H_2O

In this reaction, methane is a hydrocarbon react with the oxygen to give carbon dioxide and water as a product. So, this reaction is a combustion reaction.

Combustion reaction : A type of chemical reaction where a hydrocarbon molecule react with the oxygen to produces carbon dioxide and water as a product.

Hence, the Equation A represents a combination reaction, and equation B represents a combustion reaction.

Which element will most likely form covalent bonds with fluorine? f carbon g tin h potassium j neon?
hram777 [196]
Covalent bond is when there is relatively less difference in electronegativity of constituent atoms. On the other hand, ionic bond is formed when there is large difference in electronegativity of constituent atoms. 

In present case, electronegativity of F is 3.98, electronegativity of C is 2.55, electronegativity of tin is 1.96 and electronegativity of potassium is 0.82.

Here, since the electronegativity difference is minimum in case of C-F, so covalent bond will be preferentially with carbon. 

It must also be noted that neon is an inert gas, hence it will not form bond with F.

_______ and _______ are located in the nucleus of the atom, while _______ exist in orbitals in the empty space outside of the nu
hram777 [196]

The atomic structure of an atom is well explained experimentally by different experiments like Rutherford's experiment etc

Based on these experiments it was determined that the atoms contains a central part known as nucleus which contains the positively charged sub atomic particles protons and neutral sub atomic particles neutron.

There is empty space around the nucleus in which negatively charged subatomic particles are found known as electrons.

So answers are

a) protons

b) neutrons

c) electrons

Give the electron configurations for the elements given. use the noble gas core preceding for the inner electrons.
Umnica [9.8K]
Noble Gas Cores have following electronic configuration

He  =  1s²
Ne  =  [He] 2s², 2p⁶
Ar  =   [Ne] 3s², 3p⁶
Kr  =   [Ar] 4s², 4p⁶
Xe  =  [Kr] 5s², 5p⁶

Now solving for question elements,

Germanium = Ge  =  [Ar] 3d¹⁰, 4s², 4p²

Nickle = Ni  =  [Ar] 3d¹⁰, 4s²

Tunsten = W  =  [Xe] 4f¹⁴, 5d⁴, 6s²

Titanium = Ti  =  [Ar] 3d², 4s²

Iron = Fe  =  [Ar] 3d⁶, 4s²

Zinc = Zn  =  [Ar] 3d¹⁰, 4s²

Bose-Einstein condensation occurs at what temperature?
lyudmila [28]

Bose Einstein condensation occur at temperature very close to absolute zero i.e 273.15 degrees centigrade.. Under such conditions, large quantity of Boson occupies the lowest quantum state, at which point microscopic quantum phenomena becomes apparent macroscopically.  A BEC is formed by cooling a gas of extremely low density about one hundred thousandth the density of normal air, to ultra low temperature.
