Answer: If a mineral contains only atoms of oxygen and metal, it is most likely an oxide mineral.
Explanation:
What is [H+] given that the measured cell potential is -0.464 V and the anode reduction ... What half-reaction occurs at the cathode during the electrolysis of molten ... PbO2(s) + 4H+(aq) + SO42-(aq) + 2e- → PbSO4(s) + 2H2O(l); E° = 1.69 V .... For the cell Cu(s)|Cu2+||Ag+|Ag(s), the standard cell potential is 0.46 V. A cell ... hopw this helps
The answer would be b. Temperature of the solution increases
Temperature determines the kinetic energy of the water molecule. Higher temperature will cause the molecule to moves faster and the compound (KNO3) could break solute molecule easier make it become more soluble. A higher pressure will increase the solubility of a gas, not solid
Answer: -
D. Network
Explanation: -
Diamond is an allotrope of carbon. In diamond each carbon atom makes four bonds to other carbon atoms.
They exist in tetrahedral shape.
Diamond has strong covalent bonds. They extend in all the three dimensions
Such covalent bonds are called network covalent bonds. They require significant amounts of energy to break.
Cohesion holds hydrogen bonds together to create surface tension on water. Since water is attracted to other molecules, adhesive forces pull the water toward other molecules.
