WebNov 8, 2009 · A silicate is a salt of silicic acids and one or several metals. Orthosilicic acid, H 4 SiO 4, is just the simplest form, other silicic acids are made of several linked SiO 4 units with attached hydrogen. One could think that silicates form when a metal hydroxide and orthosilicic acid react, like H 4 SiO 4 + 2 Mg(OH) 2 → 2 H 2 O + Mg 2 SiO 4 [11] WebApr 29, 2024 · A lead-acid battery is a rechargeable battery that uses lead and sulphuric acid to function. The lead is submerged into the sulphuric acid to allow a controlled chemical reaction. This chemical reaction is what causes the battery to produce electricity. Then, this reaction is reversed to recharge the battery. Believe it or not, this technology ...

Azurite Mineral Data

WebAzurite is very popular mineral among collectors. Bright blue pieces are polished into cabochon s and beads, and large masses are sometimes cut into ornamental objects. "Azure-malachite" is also carved as cabochons and beads. Azurite was formerly crushed and used as a blue pigment. Azurite is also an ore of copper. WebAzurite often occurs with green Malachite, which may form green stains or specks on Azurite crystals or aggregates. The two minerals sometimes occur admixed or banded together, forming what is called "Azure-malachite" in the gem and mineral trades. A rarer Azurite mixture, known as "Bluebird", is Azurite mixed with dark red Cuprite. Azurite ... how many people apply to harvard
