<span>Steel is a solid at standard temperature and pressure conditions. For a solid, the particles are found to be oscillating about a fixed point. However, steel is a metal so this holds true for the positively charged nuclei of the particles. Just like any other metal, the electrons are free to move about, allowing steel to exhibit its properties such as heat conduction and electricity conduction. The reason the positive particles are fixed in place is because the intermolecular forces are very strong in solids, the strongest out solids, liquids and gases.</span>
Answer:
The statement "The total mass of hydrochloric acid and sodium hydroxide will result in the same total mass of sodium chloride and water." is true due to the Law of Conservation of Mass which states that matter cannot be created nor destroyed.
Answer:
3.44 × 10²⁴ atoms of oxygen
Explanation:
Step 1: Calculate the moles corresponding to 163 g of Al₂(SO₄)₃
The molar mass of Al₂(SO₄)₃ is 342.15 g/mol.
163 g × 1 mol/342.15 g = 0.476 mol
Step 2: Calculate the molecules in 0.476 moles of Al₂(SO₄)₃
We will use Avogadro's number: there are 6.02 × 10²³ molecules of Al₂(SO₄)₃ in 1 mole of Al₂(SO₄)₃.
0.476 mol × 6.02 × 10²³ molecules/1 mol = 2.87 × 10²³ molecules
Step 3: Calculate the atoms of O in 2.87 × 10²³ molecules of Al₂(SO₄)₃
According to the chemical equation, the molar ratio of Al₂(SO₄)₃ to O is 1:12. The atoms of O are 12/1 × 2.87 × 10²³ = 3.44 × 10²⁴.
Shows that water is a compound...
made up of 2 hydrogen atoms and 1 oxygen atom...=H2O...
decomposition of water is by electrolysis which splits the compound!
hope this helps!
