According to table g, which substance forms an unsaturated solution when 80. grams of the substance are stirred into 100. grams
e-lub [12.9K]

A saturated solution is one in which no more solute is able to dissolve in a given solvent at a particular temperature. Some amount of the solute is left undissolved in the solution.

Unsaturated solution has solute in lower proportions than required to form a saturated solution.

Supersaturated solution has solute in amounts greater than a saturated solution.

We can take the help of solubility curve in order to find out the amount of a salt required to prepare a saturated solution of that salt at a particular temperature.

The solubility of KI at 10^{0}C is 136 g/ 100 mL water

The solubility of KNO_{3} at 10^{0}C is 21 g/100 mL water.

The solubility of NaNO_{3} at 10^{0}C is 80 g/100 mL water.

The solubility of NaCl at 10^{0}C is 38 g/ 100 mL water.

So the correct answer will be KI, as it would need 136 g KI / 100 mL water to form a saturated solution at 10^{0}C.So, if we have 80g KI/ 100mL water it would be an unsaturated solution.

You receive a prescription for amoxicillin 75 mg qid for ten days. how many ml's do you need to fill this prescription to last t
pochemuha

According to the question:

Given,

= 250mg 75mg 375mg

= 5Cc X 250 X

= X = 1.5ml

= 1.5ml/dose X 4 doses/daily X 10 days = 60 ml

<h3>What do you know about amoxicillin?</h3>

Numerous bacterial infections can be treated with amoxicillin. This drug is an antibiotic similar to penicillin. It acts by preventing bacterial development. Only bacterial illnesses are treated by this antibiotic. For viral infections, it is ineffective (such as common cold, flu). Any antibiotic that is overused may stop working to treat subsequent illnesses. Along with other drugs, amoxicillin is also used to treat and prevent the recurrence of stomach / intestinal ulcers brought on by the bacteria H. pylori. Take this medication by mouth every 8 to 12 hours, generally with or without food, as prescribed by your doctor. Your medical condition and treatment response will determine the dosage.

max2010maxim [7]

Answer: Root nodules are associations between bacteria and plant roots responsible for nitrogen fixation.

Explanation:

  • As nitrogen present in atmosphere cannot be used by plants directly.
  • Nitrogen present in atmosphere is converted into nitrogen compounds by bacteria which is present in root nodules of a plant.
  • These compounds of nitrogen are then used by plants for various functions.
