Answer:

We need 128 liters of a gaseous hydrogen bromide

Explanation:

Step 1:

Temperature = 58°C

Pressure = 0.891 atm

Volume ofHydrobromic acid we want to prepare is 3.50 L (1.20M)

Step 2: Calculate moles HBr

Moles HBr = molarity * volule

Moles HBr = 1.20 * 3.50 L

Moles HBr = 4.20 moles HBr

Step 3: Calculate volume of Hydrogen bromide

pV = nRT

V=(nRT)/P

⇒ with V = the volume of gaseous hydrogen bromide = ?

⇒with p = the pressure of the gas = 0.891 atm

⇒ with n = the number of moles of hydrogen bromide = 4.2 moles

⇒ with R = the gasconstant = 0.08206 L*atm / mol*K

⇒ with T = the temperature = 58.0 °C = 273 + 58 = 331 Kelvin

V = (4.2*0.08206*331)/0.891

V = 128 L

We need 128 liters of a gaseous hydrogen bromide

What is the maximum radiation pressure exerted by sunlight in space ( s = 1350 w/m 2) on a flat black surface? a. 2. 25 × 10−5 p
mel-nik [20]

The maximum radiation pressure exerted by sunlight in space on a flat black surface is  4.5 × 10^{-6}  P a. So, the correct option is (b).

Radiation pressure is the name for the force electromagnetic wave particles exert on a surface. It is inversely related to the wave's speed. Given data

Solar constant  ( S )  =  1350W / m ^2

Now, the radiaton pressure is given by

P = 2 S /c

where c is the speed of the light

P = 2 × 1350 /3 × 10 ^8

P = 9 × 10^{-6}  P a

For a black surface, P = 4.5× 10^{-6}  P a

Therefore, maximum radiation pressure exerted by sunlight in space on a flat black surface is  4.5 × 10^{-6}  P a

A 50.5 L flask contains 3.25 mol of an unknown gas at 288.6 K, what is the pressure of<br> this gas?
Ivahew [28]

Answer:

1.52atm is the pressure of the gas

Explanation:

To solve this question we must use the general gas law:

PV = nRT

<em>Where P is pressure in atm = Our incognite</em>

<em>V is volume = 50.5L</em>

<em>n are moles of gas = 3.25moles</em>

<em>R is gas constat = 0.082atmL/molK</em>

<em>And T is absolute temperature = 288.6K</em>

To solve pressure:

P = nRT / V

P = 3.25mol*0.082atmL/molK*288.6K / 50.5L

P = 1.52atm is the pressure of the gas

3. If all the waves were measured for a period of 5 seconds, which wave had the highest frequency?
Vanyuwa [196]

Answer:

Correct answer is A.

Explanation:

Frequency is the number of oscillations that a wave have per unit time. Since time is measured in seconds, the wave with the highest frequency must register the highest number of oscillation per second. Hence, correct answer is A.
