What is the maximum amount of moles of p2o5 that can theoretically be made from 136 g of p4 and excess oxygen

The maximum number of moles of theoretically made is 2.194 moles.

Explanation:

To calculate the number of moles, we use the equation

Given mass of = 136 g

Molar mass of = 123.9 g/mol

Putting values in above equation, we get:

The chemical equation for the formation of follows:

Oxygen is present in excess, so it is considered as an excess reagent.

is considered as a limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

If 1 mole of is producing 2 moles of

So, 1.097 moles of will produce = of

Hence, the maximum number of moles of theoretically made is 2.194 moles.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.  

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
