what does our life have in common with the periodic table, What is the relationship between the world around us and the periodic table?
Answer:
Summary. To summarize, the periodic table is important because it is organized to provide a great deal of information about elements and how they relate to one another in one easy-to-use reference. The table can be used to predict the properties of elements, even those that have not yet been discovered.

How many moles of butane (C4H10(g)) were combusted in the presence of excess
oxygen gas if 55.8 L of water vapour at STP is collected?
Moles of Butane combusted : 0.4982
Further explanationGiven
55.8 water vapour at STP
Required
moles of Butane
Solution
Reaction(Combustion of Butane) :
2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O
1 mol at STP = 22.4 L, so mol of H₂O for 55.8 L :
=55.8 : 22.4
=2.491 moles
mol H₂O based on Butane as a limiting reactant(excess Oxygen)
From the equation, mol ratio Butane-C₄H₁₀ : H₂O = 2 : 10, so mol Butane :
[tex]\tt =\dfrac{2}{10}\times 2.491\\\\=0.4982[/tex]

The term "alchemy" refers to early pseudoscientific attempts to transform common
elements into more valuable elements (such as lead into gold), For one kind of atom to
become another kind of atom, which particle(s) of the atom need to be expelled or gained?
Proton
Electron
Neutron
Quantum Particles
Answer: The correct answer is option B. electron.
Explanation:
There are 3 subatomic particles:
Electrons: They carry negative charge and are present in orbits around the nucleus of an atom.Protons: They carry positive charge and are present inside the nucleus of an atomNeutrons: They does not carry any charge and are present inside the nucleus of an atom.An atom forms an ion, when it looses or gains an electron.
When an atom looses electron, it form a positive ion known as cation.When an atom gains electron, it form a negative ion known as anion.Hence, the correct answer is option B. electron.
The particle(s) of the atom that is needed to be expelled or gained in an alchemy process which involves transformation of one element into valuable elements or atom to another is B:Electron.
Alchemy can be regarded as branch of philosophical and protoscientific tradition that is traceable to China, and Europe. In the process of transformation of one element to another useful element or compounds , there is usually transfer of electron.Electronegative element like chlorine usually gain electron and are anion, while electropositive elements like potassium will loose electron( cation) all involves the transfer of electron.
Therefore, option B is correct.

Earth’s magnetic field is generated by a conducting fluid in its core. Explain why this is a theory.
Answer:
It's not a theory, The magnetic pull is from the core of the earth and pulls you down. example: I can jump and fall, Why? because of the core of the earth of me going p and then down. Why do you think that space doesn't have gravity? It's because it doesn't have a core, There are no planets that pull you down enough like earth.
