1) Given the balance equation below. Calculate how much Na3PO4 in grams you
juin [17]

Answer:

<u>136.67 g of Na3PO4 i</u>s required to create 100 gram of NaOH.

Explanation:

The balanced equation:

Na_{3}PO_{4} + 3 KOH \rightarrow 3 NaOH + K_{3}PO_{4}

1 mole Na3PO4 = 164 g/mole (Molar mass)

1 mole NaOH = 40 g/mole (Molar mass)

Now,

1 mole of Na3PO4 produce = 3 mole of NaOH

164 g/mol of Na3PO4 produce = 3(40) g/mol of NaOH

or

120 g/mol of NaOH is produced from = 164 g/mol of Na3PO4

1 g/mol of NaOH is produced from =

\frac{164}{120}

100 grams of NaOH is produced from =

\frac{164}{120}\times100 gram of Na3PO4

calculate,

= 136.67 g

What should be the effect of losing ones sight on the ability to digest food
crimeas [40]

One mechanism is enzyme induction.

Enzymes are proteins, which are metabolically expensive to produce. It makes evolutionary sense that your body makes less digestive enzymes such as lactase and sucrase when they're not needed. If your diet changes, your body can gradually increase the production of some enzymes through a process of enzyme induction.

For example, the production of lactase enzyme can be increased in some lactose-intolerant individuals by feeding them lactose . Also, studies in rats have shown that other carbohydrate-digesti<span>Your body makes more of what it needs, and less of what it doesn't need--brilliant!</span>ng enzymes, such as sucrase-isomaltase, trehalase, and maltase-glucoamylase--can be induced by hydrocortisone administration.
