Answer:
Artificial diamonds are made using thallium carbonate. If thallium has an oxidation number of 1+ number 2 A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds. number 3 giant metallic, giant ionic, simple molecular, and macromolecular ... it has positive ions surrounded by a sea of delocalised electrons ... m/z value than Cl⁻. this means that F⁻ is more attracted to the Ca²⁺ ion more strongly ... What bond angle does beryllium chloride, BeCl₂ have? ... Give two examples of linear molecules.
The primary greenhouse gases<span> in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Without </span>greenhouse gases<span>, the average temperature of Earth's surface would be about −18 °C (0 °F), rather than the present average of 15 °C (59 °F).</span>
O2 is water.
But the Wannsee and answer is c
1) Balanced chemical reaction:
2HClO₄(aq) + K₂CO₃(aq) → K₂CO₃(aq) + CO₂(g) + H₂O(l).
2) Balanced chemical reaction:
HC₂H₃O₂(aq) + LiHSO₃(aq) → LiC₂H₃O₂(aq) (aq) + SO₂(g) + H₂O(l).
3) Balanced chemical reaction:
(NH₄)₂SO₄(aq) + Ca(OH)₂(aq) → CaSO₄(s) + 2NH₃(g) + 2H₂O(l).
CaSO₄ (calcium sulfate) is insoluble in water.
