Answer:

Explanation:
Hello, in this case, one could consider the undergoing chemical reaction as:

Thus, since 1.0 g of strontium carbonate is placed, the equilibrium equation takes the following form, excluding the solid-stated species and considering just the carbon dioxide as it is gaseous:

Hence, since at the beginning there is no carbon dioxide, its pressure at equilibrium equals Kp:

Which was clearly defined above.
Best regards.
Hydrogen is the smallest chemical element because it consists of only one proton in its nucleus. Its symbol is H, and its atomic number is 1 .It has an average atomic weight of 1.0079 amu, making it the lightest element.
a.1.00784 u
b.Atomic-36
Kr
Krypton
Atomic Weight. 83.80
That means that there must be a balance between the positively charged protons and the negatively charged electrons. Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons since it contains 36 protons. Electrons are arranged around atoms in a special way.

An atom is neutral as it has the same number of electrons that of protons. So, if an atom has 32 protons i.e. the atomic number of it is 32, then it will have 32 electrons revolving the nucleus.
