[50 PTS] show does the arrangement of elements on the periodic table relate to their chemical properties?
slava [35]

YES, the arrangement of elements on the periodic table relate to their chemical properties

Explanation:

As you move across a period, the atomic radius decreases due to the increase in atomic mass and hence attraction of orbitals by the increasingly positive nucleus. Therefore, the atoms become increasingly harder to lose electrons (due to increasing ionization energy) in their valence shell and more likely to take up electrons in chemical reactions.

The lower you go down the periodic table the higher the reactivity of the atoms. This is because they have more electron shells and the valence electrons are shielded from the atomic nuclei by underlying orbitals. This means that the valence electrons are easily lost (ionization energy is low) and can, therefore, react fast in chemical reactions.

Which type of energy is stored in the nucleus of an atom?
Lapatulllka [165]
Nuclear energy is energy in the nucleus (core) of an atom. Atoms are tiny particles that make up every object in the universe. There is enormous energy in the bonds that hold atoms together. Nuclear energy can be used to make electricity.

Calculate the mass of water produced when 42 g of propane, c3h8, is burned with 115 g of oxygen
gavmur [86]
The balanced combustion reaction of propane, C₃H₈, is

C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O

Molar mass of propane: 44 g/mol
Moles of propane = 42 g * (1 mol/44g) = 0.9545 mol propane

Molar mass of oxygen: 32 g/mol
Moles of oxygen = 115 g * (1 mol/32 g) = 3.594 mol oxygen

Moles of oxygen needed to completely react propane:
0.9545 mol propane * (5 mol O₂/1 mol propane) = 4.7725 mol oxygen

Since the available oxygen is only 3.594 moles and propane needs 4.7725 moles, that means oxygen is our limiting reactant. We base the amount of water produced here.

Molar mass of water: 18 g/mol
Mass of water produced = 3.594 mol O₂ * (4 mol H₂O/5 mol O₂) * (18 g/mol)
Mass of water produced = 258.768 grams
