Answer:
magnesium + water == magnesium oxide + hydrogen
In recent years, researchers have tried to capture the electrical current that bacteria generate through their own metabolism. So far, however, the transfer of the current from the bacteria to a receiving electrode has not been efficient at all.
Answer:
the answer is A An atomic orbital can only hold a maximum of 2 electrons, each with opposite spins
Explanation:
Answer is: D. The I⁻ ion and the positive end of a water molecule.
Dissociation of potassium iodide in water:
KI(aq) → K⁺(aq) + I⁻(aq).
Solvation is the interaction of solvent (water) with molecules or ions (in this example K⁺ and I⁻) in a solute.
Anion I⁻ has negative charge, so positive end (hydrogen atoms) of a water molecul attracts them.
Solvent (usually a liquid, but can also be a solid or a gas) is a substance that dissolves a solute.
