What is similar about the atomic structure of the copper isotopes?

1 answer:

3 0

All copper atoms have atomic number 29: all their nuclei contain 29 protons. But they also contain uncharged particles called neutrons. ... The two different kinds of atom are called isotopes of copper. The neutron has a mass very similar to that of the proton, so the two isotopes differ in mass.

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

How do you know if the reaction is exothermic

MArishka [77]

Hey there!
Exothermic reactions release heat, causing its temperature to fall. If the reaction is lessening the temperature of the object while releasing all the heat, then you know that the reaction is indeed exothermic. Hope this helps!
