Ko te tāpiritanga o te irahiko, te tangohanga o te hāora (O), te tāpiritanga rānei o te hauwai (H) i tētahi tauhohe matū. Ko te tauhohenga o te rino ōkai (Fe2O3) me te waro hāora-tahi (CO) hei whakaputa i te rino (Fe) tētahi tauira o te tauhohe ōheketanga.
The gaining of electrons, the loss of oxygen or the gaining of hydrogen atoms in a chemical reaction. The reduction of iron oxide (Fe2O3) by carbon monoxide (CO) to produce iron (Fe) is an example of a reduction reaction.
tauhohe - reaction
heke - descend
He aha ngā pūmatū hohe o te tauhohe ōheketanga?
Whakamāramatia mai he aha i kīia ai tētahi tauhohenga he tauhohe ōheketanga.
I te tauhohe ōheketanga, ka wetekina ngā ngota hāora o tētahi o ngā pūmatū hohe, ā, ka hono atu ai ki tētahi atu o ngā pūmatū hohe.
