Koia nei ētahi āhuatanga ka hua ake i te tauhohe matū:

Ko te pūmau o te papatipu tētahi ture e mea ana, he ōrite te papatipu o ngā pūmatū hohe me te papatipu o ngā pūmatū hua i muri i te tauhohenga.

E taea ana te tauhohe matū te whakaatu ki te whārite matū. Ko ngā pūmatū hohe ki te taha mauī, ko ngā pūmatū hua ki te taha matau, ko te tohu '→' ki waenganui. E tika ana kia rite ngā ngota ki ia taha o te tohu '→', ka kīia he whārite matū taurite.

Hei tauira: Ka hua mai te hauhā (CO2) mai i te tauhohenga o te waro (C) me te hāora (O2). E rua ngā ngota hāora, ka hono atu ki te ngota waro kotahi: C + O2 → CO2

I ētahi tauhohe matū, ka whakaputaina te pūngao pōkākā. Ka kīia he tauhohe putawera. I ētahi tauhohe matū, mā te pā rawa o te pūngao pōkākā e tutuki ai te tauhohe. Ka kīia he tauhohe pauwera.
