Electronegative. Electronegativity is the tendency for an atom to pull more electrons. Fluroine is the most electronegative element, and the trend is up and to the right of the periodic table, with the exception of the noble gases.

Be sure to answer all parts. Write an unbalanced equation to represent each of the following reactions: Do not include phase abb

Eva8 [605]

Answer: The unbalanced chemical equations are written below.

Explanation:

An unbalanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is not equal to the total number of individual atoms on the product side. These equations does not follow law of conservation of mass.

For a:

The chemical equation for the reaction of nitrogen gas and oxygen gas follows:

$N_2+O_2\rightarrow NO_2$

The product formed is nitrogen dioxide.

For b:

The chemical equation for the decomposition of dinitrogen pentaoxide follows:

$N_2O_5\rightarrow N_2O_4+O_2$

The product formed is dinitrogen tetroxide and oxygen gas.

For c:

The chemical equation for the reaction of ozone to oxygen gas follows:

$O_3\rightarrow O_2$

The product formed is oxygen gas.

For d:

The chemical equation for the reaction of chlorine and sodium iodide follows:

$Cl_2+NaI\rightarrow NaCl+I_2$

The product formed is sodium chloride and iodine gas

For e:

The chemical equation for the reaction of magnesium and oxygen gas follows:

$Mg+O_2\rightarrow MgO$

The product formed is magnesium oxide

Write the symbols for the following isotopes: Its atoms contain 50 electrons and 70 neutrons

Veronika [31]

Since this element has 50 electrons you know that it has 50 protons. The number of proton= the atomic number. Atomic number 50 is tin. The atomic symbol for tin is Sn and the weight is 120. So this is the tin 120 isotope

Question 11 (1 point)

erastova [34]

Answer:

remove product

Explanation:

Removing the product will always shift the equilibrium to the right. This is based on the Le Chatelier's principle which states that "if any of the conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".

If a system at equilibrium is disturbed, by changing the concentration of one of the substances all the concentrations will change until a new equilibrium point is reached.
Removing the product will increase the concentration of the species on the left hand side, the equilibrium will shift to the right.
