5 0

Answer:An iodide ion is the ion I−. Compounds with iodine in formal oxidation state −1 are called iodides. This page is for the iodide ion and its salts, not organo iodine compounds. In everyday life, iodide is most commonly encountered as a component of iodized salt, which many governments mandate.

How many moles of gas are present when you collect 35.83 mL of the gas over water at 25.3°C and 0.97 atm?
Oksana_A [137]
Use Ideal Gas equation since values are given in Pressure (P), Volume (V), Temperature (T). 
                                 P V = n R T ; n= PV / RT
You can't use 1 mole= 22.4 L equation. Temperature and pressure values are not standard. ( 1 atm, 0 

To choose the value of R ( gas constant), check out the units of other values in the equation. They are in atm,liter, kelvin, and mole.  So, its value is 0.082 L atm/ K mol.

P= 0.97 atm
V= 35.83 * 10 ⁻³ L (conversion from ml to,  just multiplied by 10 ⁻³ )
R= 0.082 L atm/ K mol
T= (25.3 + 273) K ( recall Kelvin = Celcius + 273; K= °C + 273<span>)
</span>
Substitute values into equation of  n= PV / RT

n= 
(0.97 atm) (35.83 * 10 ⁻³ L) /  (0.082 L atm/ K mol) (298.3 K)= 0.014 mole

The answer is 0.014 mole

What is the molarity of a solution that contains 40. grams of NaOH in 0.50 liter of solution
statuscvo [17]

Answer:

The molarity of the solution is: 2 M

Explanation:

We calculate the weight of 1 mol of NaOH:

Weight 1 mol NaOH= Weight Na + Weight 0 + Weight H= 23 g+16g+ 1 g= 40g/mol

The molarity is the quantity of moles in 1000ml (1 liter) of solution:

0,5liter-----40 grams NaOH

1 liter----x=(1 liter x 40 grams NOH)/0,5 liter = 80 grams NaOH

40 grams----1 mol NaOH

80 grams----X=(80 grams x 1 mol NaOH)/40 grams= 2 mol NaOH--> 2M

Solutions with a higher concentration of solutes than the concentration inside the cell are: Solutions with a higher concentrati
Nadusha1986 [10]

Answer:

A

Explanation:

A hypertonic solution is one in which the concentration of the solute is greater than that of those inside the cell. This means that there is a solution with a higher concentration of solute compared to what is obtainable inside the cell environment.

Hence, we say that the solutions are hypertonic since they contain essentially solutes that are more concentrated than those inside the cell
