E Milieutechnologie oefeningen 1) SO2 (7pt) a) impact op mens en op het milieu mens: heeft een effect op de luchtwegen. Is redelijk goed oplosbaar in water en irriteert de slijmvliezen. Hierdoor verhoogt de weerstand van de luchtwegen. Blootstelling aan SO2 verhoogt de inspanning om te ademen en stimuleert afscheiding van slijm. SO2 verlamt ook de trilhaartjes in de luchtpijp waardoor deeltjes makkelijker de longen kunnen binnen dringen. Milieu: zure neerslag, verzuring. Verzuring mere...

Chemical bonding refers to the attractive forces that hold atoms together in a compound. There are three main types of chemical bonds: ionic, covalent, and metallic. Ionic bonding occurs when there is a transfer of electrons between atoms, resulting in the formation of ions that are held together by electrostatic forces. Covalent bonding occurs when atoms share electrons in order to complete their valence shells, resulting in the formation of a molecule. Metallic bonding occurs when there is a s...
