Chemistry
1 answer:
LiRa [457]3 years ago
3 0

Answer:

The proportion of dissolved substances in seawater is usually expressed in ppm, ppb or ppt

Explanation:

The concentration of very diluted solutions should be expressed in parts per million, billion or trillion.

ppm = mass from the solute . 10⁶ / mass or volume of the solution

ppb = mass from the solute . 10⁹ / mass or volume of the solution

ppt = mass from the solute . 10¹² / mass or volume of the solution

ppm = mg/kg, μg/g, μg/mL → These are the units

ppb = ng/g

ppt = pg/g

How much heat is lost when 0.440 mol of steam condenses at 100 °C?
dusya [7]

Answer:

17,890 J

Explanation:

The amount of heat released by a gaseous substance when it condenses is given by the formula

Q=n\lambda_v

where

n is the number of moles of the substance

\lambda_v is the latent heat of vaporization

The formula can be applied if the substance is at its vaporization temperature.

In this problem, we have:

n = 0.440 mol is the number of moles of steam

\lambda_v=40,660 J/mol is the latent heat of vaporization of water

And the steam is already at 100C, so we can apply the formula:

Q=(0.440)(40660)=17,890 J

Maalox is the trade name for an antacid and antigas medication used for relief of heartburn, bloating, and acid indigestion in which

4 ml contains

= 320mg of aluminum hydroxide

= 320mg of magnesium hydroxide

= 32mg of simethicone

recommended doses = 4 times * 2 tea spoon = 8 tea spoon/ day

given = 1 tea spoon = 5 ml

8 tea spoon = 40 ml

hence,

amount of aluminum hydroxide = 320/4 * 40 = 3200mg = 3.2 g

amount of magnesium hydroxide = 320/4 * 40 = 3.2 g

amount of  simethicone = 32/4 * 40 = 320 mg = 0.32g
