He shows that he is still acting around us by showing how powerful he is and that to remind us that he still does things on this earth and still acts around this earth.
1) Preliminar explanation:
Atoms are neutral spieces: they have the same number of positive charges (protons inside the nucleous) as of negative charges (electrons around the nucleus).
Ions are formed by the gain or loss of electrons.
Positive ions are formed when neutral the atoms lose electrons, and negative ions are formed when neutral atoms gain electrons. Only the elctrons are gain or loss in ions formation (the number of protons remain unchanged).
2) Conclusion (answer)
Therefore, mathematically an ion is the result of adding or subtracting electrons to an atom, creating an imbalance of charge, positve when the atom ends up with less electrons than protons (loss of electrons) or negative when the atoms ends up with more electrons than protons (gain of electrons).
Chemical property is when it's observed during a reaction in which the chemical composition or identity of the substance is changed. physical properties is when properties that do change the chemical nature of matter.
example for this is smell, color, freezing point, etc.
Answer:
Number of produced moles of carbondioxide is 0.113 mol.
Explanation:
Excess of sulphuric acid is present.And the sodium carbonate is completely consumed.
Molar mass of sodium carbonate = 105.99g/mol
Given mass of sodium carbonate =12 g/mol
one mole of sodium carbonate produce one mole of carbondioxide.
0.113 mole of sodium carbonate produce 0.113 mole of carbondioxide.
Therefore, 0.113 mol of carbondioxide produced in flask 7.
