Select the more electronegative element in each pair.a.Cl or Fb.Se or Oc.N or Asd.Na or Mg
liubo4ka [24]

Answer:

The answer to your question is below

Explanation:

Electronegativity is a measure of how strongly atoms attract electrons to themselves.

Process

Look for the electronegativity of each element and compare.

a) Cl = 3.16   F = 3.98          Fluorine has a higher electronegativity

b) Se = 2.55 O = 3.44         Oxygen has a higher electronegativity

c) N = 3.04 As = 2.18         Nitrogen has a higher electronegativity

d) Na = 0.93 Mg = 1.31       Magnesium has a higher electronegativity

Which statement defines dynamic equilibrium? (5 points)
Shalnov [3]

Answer:

1. A state of balance in which the rates of the forward and reverse reactions are equal.

Explanation:

A dynamic equilibrium is like a cycle, the reactants change to products, but the products also change to reactants keeping the amount of each constant.

2. A state of balance in which the forward reaction stops but reverse reaction continues.

In this statement there isnt a equilibrium. The products will change to reactants until the reaction stops.

3. A state of balance in which the forward reaction continues but reverse reaction stops.

Here the reactants will change to products until the reaction stops.

4. A state of balance in which the forward and reverse reactions stop.

In this case the reaction has stopped.

For an experiment, you place 15 g of ice with a temperature of -10 C into a cup and label
melamori03 [73]
The correct answer is c. Temperature is the average kinetic energy of a sample so if two samples have the same temperature they will also have the same average kinetic energy. I hope this helps. Let me know if anything is unclear.
