Answer:
Magnesium is known for a long time as the lighter structural metal in the industry, due to it's low weight and to it's capability of forming mechanically resistant alloys.
Answer:
Can be produced 288mL of SO₂
Explanation:
Based in the reaction:
P₄S₃ + 8O₂ → P₄O₁₀ + 3SO₂
<em>Where 1 mole of tetraphosphorus trisulfide reacts producing 3 moles of sulfur dioxide gas.</em>
0.869g of tetraphosphorus trisulfide (Molar mass of P₄S₃: 220.09g/mol) are:
0.869g P₄S₃ ₓ (1mol / 220.09g) = 3.948x10⁻³ moles of P₄S₃
As 3 moles of SO₂ are produced per mole of P₄S₃:
3.948x10⁻³ moles of P₄S₃ ₓ (3 moles SO₂ / 1 mole P₄S₃) = 0.0118 moles SO₂
Using PV = nRT
V = nRT / P
<em>Where n are 0.0118 moles, R gas constant (0.082atmL/molK), T absolute temperature (21.0°C + 273.15K = 294.15K), and P pressure (751torr / 760 = 0.988atm).</em>
Replacing:
V = 0.0118molₓ0.082atmL/molKₓ294.15K / 0.988atm
V = 0.288L = 288mL

Answer: The nuclear symbol of an isotope indicates the number of protons and neutrons in an atom of the element. It does not indicate the number of electrons. The number of neutrons is not stated. Instead, you have to figure it out based on the number of protons or atomic number.
