Most lakes have rivers flowing out of them, carrying water to the ocean. However, some lakes, including the Great Salt Lake and
Ray Of Light [21]

The lack of an outlet will affect the composition of these lakes by causing an accumulation of organic and inorganic nutrients due to decomposition of living materials.

<h3>What is a lake?</h3>

Lake is a small stream of running water or a channel for water.

Lakes are usually a standing body of water or slow moving. This means that some lakes, including the Great Salt Lake and the Dead Sea, have no outlet.

The lack of an outlet will affect the composition of these lakes by causing an accumulation of organic and inorganic nutrients due to decomposition of living materials.

What is the oral dose of aluminum hydroxide for an adult being treated for hyperacidity? What is the oral dose of aluminum hydro
Vsevolod [243]

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.

Choose the aqueous solution that has the highest boiling point. These are all solutions of nonvolatile solutes and you should as
UNO [17]

Answer: 0.100 m K_2SO_4

Explanation:

Elevation in boiling point is given by:

\Delta T_b=i\times K_b\times m

\Delta T_b=T_b-T_b^0 = Elevation in boiling point

i= vant hoff factor

K_b = boiling point constant

m= molality

1. For 0.100 m K_2SO_{4}

K_2SO_4\rightarrow 2K^{+}+SO_4^{2-}  

, i= 3 as it is a electrolyte and dissociate to give 3 ions. and concentration of ions will be 3\times 0.100=0.300

2. For 0.100 m LiNO_3

LiNO_3\rightarrow Li^{+}+NO_3^{-}  

, i= 2 as it is a electrolyte and dissociate to give 2 ions, concentration of ions will be 2\times 0.100=0.200

3.  For 0.200 m C_2H_8O_3

, i= 1 as it is a non electrolyte and does not dissociate, concentration of ions will be 1\times 0.200=0.200

4. For 0.060 m Na_3PO_4

Na_3PO_4\rightarrow 3Na^{+}+PO_4^{3-}  

, i= 4 as it is a electrolyte and dissociate to give 4 ions. and concentration of ions will be 4\times 0.060=0.24m

Thus as concentration of solute is highest for K_2SO_4 , the elevation in boiling point is highest and thus has the highest boiling point.

A substance present before chemical reaction occurs is?
Arisa [49]

Answer:

The substance (or substances) initially involved in a chemical reaction are called reactants or reagents. Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants.
