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

Help! I don't have the things to do this and its due TODAY! Could someone help me?

vodomira [7]

Answer:

--- The hot air inside the bottle creates an expansion and when the hot water is applied a contraction occurs, thus causing the balloon to be sucked.

--- An internal pressure is produced, joining the heat begins to decrease. As a consequence, the air molecule causes the balloon to enter the bottle thanks to the effect of the external pressure.

Explanation:

I hope I have helped with something.

Intermolecular forces do not have any effect on determining the physical properties of

djyliett [7]

Answer:

False

Explanation:

The physical properties of melting point, boiling point, vapor pressure, evaporation, viscosity, surface tension, and solubility are related to the strength of attractive forces between molecules. These attractive forces are called Intermolecular Forces.

Why did the results pf the cathode ray tube require a new model of the atom

aleksandr82 [10.1K]

J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. ... Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus.
