If two atoms have an electronegativity difference of 1.3, what type of bond would form between them?
Debora [2.8K]

Answer:

The correct answer is b polar covalent

Explanation:

When two atoms joined by covalent bond has difference in their electronegativities at that time polarity arise.

    When the electronegativity difference is low such as 1.3 then the polar bond formed by the two atoms are called polar covalent bond.For example H2O

 on the other hand polar bond formed by two atoms having high difference in their electronegativities is called ionic bond.For example NaCl.

When a reaction has reached equilibrium... A. Q = K B. The rate of the forward reaction and the rate of the reverse reaction are
grin007 [14]

Answer:

The correct answer is option A.

Explanation:

Equilibrium is a state when rate of forward reaction is equal to the rate of backward reaction. The concentration of reactants and products becomes constant at this state.

The ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric coefficients is termed as Equilibrium constant. It is denoted by K_{eq}.

aA + bB \rightleftharpoons cC

K_{eq}=\frac{[C]^c}{[A]^a[B]^b}
