H₂O + H₂O ⇌ H₃O⁺ + OH⁻
You use two single-barbed arrows pointing in opposite directions (technically rightwards harpoon over leftwards harpoon) <em>to indicate a reversible reactio</em>n.
Answer:
273 K
Explanation:
The temperature of a gas at STP is 273 K. This is equal to 0°C or 32°F.
Answer:
2HCI + Na2S - > H2S + 2NaCl
Explanation:
2HCI + Na2S -> H2S + 2NaCl
before reaction: 2H, 2Cl, 2Na, 1S
after reaction: 2H, 2Cl, 2Na, 1S
Answer:
the number of solute particles increases
Noble Gas Cores have following electronic configuration
He = 1s²
Ne = [He] 2s², 2p⁶
Ar = [Ne] 3s², 3p⁶
Kr = [Ar] 4s², 4p⁶
Xe = [Kr] 5s², 5p⁶
Now solving for question elements,
Germanium = Ge = [Ar] 3d¹⁰, 4s², 4p²
Nickle = Ni = [Ar] 3d¹⁰, 4s²
Tunsten = W = [Xe] 4f¹⁴, 5d⁴, 6s²
Titanium = Ti = [Ar] 3d², 4s²
Iron = Fe = [Ar] 3d⁶, 4s²
Zinc = Zn = [Ar] 3d¹⁰, 4s²
