Jifunze misingi kuhusu electrolysis. Electrolysis ni mtiririko wa umeme wa sasa kupitia kioevu ambayo husababisha mabadiliko ya kemikali. Kioevu kinaweza kuwa kiwanja cha ionic kilichochombwa au suluhisho la maji. Kioevu kitakuwa na ions chanya zinazozunguka bure na ions hasi. Ions chanya huitwa cations, na ions hasi huitwa anions. Electrodes huingia ndani ya kioevu (ufumbuzi wa electrolyte) na kushikamana na kiini cha umeme. Electroni zitaanza kuzunguka kwenye waya na hii itasababisha electrode moja kuwa chaji chanya (anode) na nyingine kushtakiwa vibaya (cathode). Hii ina athari ya haraka ya kugonga katika kioevu kilichochombwa, na ions ndani yake. Ions chanya katika kioevu (electrolyte) huvutiwa na electrode hasi (cathode). Ions hasi katika kioevu (electrolyte), itavutiwa na electrode nzuri (anode). Hii ni kwa sababu mashtaka kinyume ya umeme huvutia. Wakati ions kukutana na electrodes, kubadilishana elektroni hutokea na hii husababisha mmenyuko wa kemikali. Kumbuka kwamba electrolysis pia inaweza kufanyika katika ufumbuzi wa ionic pamoja na misombo ya kuyeyuka. Zaidi ya kujilimbikizia suluhisho, kiwango cha mtiririko wa ion zaidi. Kiwango cha mtiririko wa ioni pia kinaweza kuongezeka kwa kuongeza tofauti ya uwezo au voltage kote kiini.

In this video, we are going to look at parallel lines. To find the equation of parallel lines, we still use the y=mx + c equation, and because they have the same gradient, we know straight away that the gradient ‘m’ will be the same. We then just need to find the missing y-intercept ‘c’ value. VISI
Plants have developed responses called tropisms. A tropism is a growth in response to a stimulus; so light and water in the plant’s case. There are different types of tropisms: Positive tropisms are when growth is towards the stimulus - so the plant growing towards the light to maximise the stimul
