Answer:Cl2

Explanation:

Diatomic gases always possess dispersion forces as their strongest intermolecular force. Dispersion forces are the primary intermolecular interaction existing between gases containing homonuclear covalent bonds. The other substances mentioned either possess a permanent dipole, or are purely ionic in nature. Hence the answer!

Answer: 2C_2H_6+7O_2\rightarrow 4CO_2+6H_2O

Explanation:

Combustion is a chemical reaction in which hydrocarbons are burnt in the presence of oxygen to give carbon dioxide and water.

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products formed must be equal to the mass of reactants taken. In order to get the same mass on both sides, the atoms of each element must be balanced on both sides of the chemical equation.

The balanced combustion reaction is,:

2C_2H_6+7O_2\rightarrow 4CO_2+6H_2O

Solving stoichiometry problems that involve mass Now that you know the molar masses of the relevant compounds, you are ready to
Shalnov [3]

14.85 g of water

Explanation:

Calculate the mass of water produced when 9.56 g of butane reacts with excess oxygen.

Here we have the full oxidation of butane (C₄H₁₀) which produce carbon dioxide and water.

C₄H₁₀ + (13/2) O₂ → 4 CO₂ + 5 H₂O

number of moles = mass / molecular weight

number of moles of butane = 9.56 / 58 = 0.165 moles

Now, taking in account the chemical reaction, we devise the following reasoning:

if         1 mole of butane produces 5 moles of water

then    0.165 moles of butane produces X moles of water

X = (0.165 × 5) / 1 = 0.825 moles of water

mass = number of moles × molecular weight

mass of water = 0.825 × 18 = 14.85 g

Why is the outermost shell of an atom significant?
Gala2k [10]

Answer:

The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms. This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons
