So, with Klebsiella, urease makes urea dissociate into carbon dioxide and ammonia.

肺炎克雷伯杆菌产生的脲酶使得尿素分解成二氧化碳和氨。

So, with Staph saprophyticus, urease makes urea dissociate into carbon dioxide and ammonia.

腐生葡萄球菌中的脲酶可使尿素分解为二氧化碳和氨气。

So HClO4 is perchloric acid and it dissociates into an anion called perchlorate.

所以 HClO4 是高氯酸， 它会分解成一种叫做高氯酸盐的阴离子。

Staph saprophyticus is also urease positive, meaning it produces an enzyme called urease that dissociates urea into carbon dioxide and ammonia.

腐生葡萄球菌也是脲酶（尿素酶）阳性的，这意味着它会产生一种称为脲酶（尿素酶）的酶，能将尿素分解为二氧化碳和氨气。

So, if catalase is present, like in staph saprophyticus, it makes hydrogen peroxide dissociate into water and oxygen, making the mixture foam.

如果存在过氧化氢酶（如腐生葡萄球菌），它会使过氧化氢分解成水和氧气，使混合物出现泡沫。

When it dissolves, it tends to dissociate into a water molecule and a lone oxygen ion.

当它溶解时， 它倾向于分解成一个水分子和一个单独的氧离子。

Alright, now Klebsiella pneumoniae is urease positive, which means it can produce an enzyme called urease that dissociates urea into carbon dioxide and ammonia.

肺炎克雷伯杆菌脲酶阳性，可以产生脲酶，将尿素分解成二氧化碳和氨。

And of course, some things dissolve in water but don't conduct electricity at all, because they don't dissociate into ions.

当然， 有些东西溶于水但根本不导电，因为它们不会离解成离子。

No matter how it gets there, carbon dioxide reacts with water to form carbonic acid; a weak acid that dissociates into hydrogen and bicarbonate ions.

无论它如何到达那里， 二氧化碳都会与水反应形成碳酸；一种离解成氢离子和碳酸氢根离子的弱酸。
