Answer:
50mL of 4M NaCl, 80mL of 40% glucose, 20mL of 1M Tris-HCl (pH 8.5) and 250mL of water.
Explanation:
To make 400mL containing 0.5M NaCl you need to add:
4M / 0.5M = 8 (dilution 1/8). 400mL / 8 = <em>50 mL of 4M NaCl.</em>
Glucose 8% you need to add:
40% / 8% = 5 (dilution 1/5). 400mL / 5 = <em>80 mL of 40% glucose </em>
Buffer 50mM you need to add:
1000mM / 50mM = 20 (dilution 1/20). 400mL / 20 = <em>20mL of 1M Tris-HCl (pH 8.5)</em>
<em></em>
The resting volume: 400mL - 50mL of 4M NaCl - 80mL of 40% glucose - 20mL of 1M Tris-HCl (pH 8.5) = 250 mL must be completed with water.
Thus, to make the solution you need: <em>50mL of 4M NaCl, 80mL of 40% glucose, 20mL of 1M Tris-HCl (pH 8.5) and 250mL of water.</em>

Benzene is produced as a side product when water react with phenyl magnesium bromide during Grignard reactions.
<h3>What is Grignard Reaction ? </h3>
The Grignard reaction involves an R-Mg-X, a carbon chain bound to a magnesium halide, used to form alcohols by attacking carbonyls such as in aldehydes or ketones.
Here R act as a nucleophile and Mg-X act as a electrophile. Instead of attacking carbonyl, which is present in the reaction, the benzene ring will attack water molecules present around, grabbing a H⁺ and pushing away MgBr .
The required reaction is :
PhMgBr + H₂O → Ph-H + MgBrOH
Thus from the above conclusion we can say that it is always advised to use dry Grignard to avoid this reaction.

Hi there! Relative order is an advanced order type and a absolute date is the process of determing a age.
Explanation:
Aluminum hydroxide is used as an antacid to counteract hyper acidity associated with the gastritis and peptic ulcer disease which includes duodenal ulcer and gastric ulcer and hiatal hernia.
<u>
Oral dosage (oral suspension)
</u>
Adults
Recommended OTC dose of aluminum hydroxide is 10 mL PO 5—6 times per day, after having meals and at bedtime.
Children
Recommended OTC dose of aluminum hydroxide is 5—15 mL PO every 3—6 hours, or 1 and 3 hours after having meals and at bedtime.
Infants
Recommended OTC dose of aluminum hydroxide is 1—2 mL/kg PO per dose and should be given 1—3 hours after having meals and at bedtime.
I dont seee a picture? or anything?
