A gas occupies 1.00 L at standard temperature. What is the volume at 333.0°C?

1 answer:

7 0

We use Charles's Law: V1/T1=V2/T2

Standard Temperature: 0 degree Celsius= 273K
333.0 degrees Celsius= 606K

Set up: (1.00L)/ (273K)= V2/ (606.0K)
⇒ V2= (1.00L)/ (273K)* (606.0K)= 2.22L

Hope this would help :))

posledela

Answer:

0.00011 JK.

The process does NOT violate the second law of thermodynamics

Explanation:

The following parameters are given which are going to help in solving for the change in entropy of the system. The term "entropy'' simply means the degree of disorderliness of a system.

=> The temperature of container A = 305 K, the temperature of container B = 295 K and the amount of heat generated when the containers are placed in contact with each other = 1. 1 J.

The change in entropy of the hot container = -(1/305) = - 0.00328 J/K.

The change in entropy of the cold container = 1/295 = 0.00339 J/K.

Therefore, the change in the entropy of the system = - 0.00328 J/K + 0.00339 J/K = 0.00011 JK.

Note that the change in entropy of the system gives a positive value. Hence, this process does not violate the second law of thermodynamics.

The process does NOT violate the second law of thermodynamics.

Key terms: Reset ____________ anions are strong nucleophiles that open epoxide rings by an SN2 mechanism. ____________ tautomers

iogann1982 [59]

Answer:

Acetylide , Enol ,aldehydes, tautomers, alkynes , Hydroboration, Keto

Explanation:

Reset Acetylide anions are strong nucleophiles that open epoxide rings by an SN2 mechanism. Enol tautomers have an O-H group bonded to a C=C. aldehydes are formed from terminal alkynes with the addition of water using BH3 then H2O2. tautomers are constitutional isomers that differ in the location of a double bond and a hydrogen and exist in an equilibrium with each other. alkynes are compounds that contain a carbon-carbon triple bond. Hydroboration of a terminal alkyne adds BH₂ to the less substituted, terminal carbon. Keto tautomers have a C=O and an additional C-H bond.

Mr. Aguilar has ice on his wrist, literally. If the ice on Mr. Aguilar’s wrist (H2O) weighs 546 grams, how many ice particles ar

Lunna [17]

Answer:

The answer to your question is 1.83 x 10²⁵ particles

Explanation:

Data

particles of H₂O = ?

mass of H₂O = 546 g

Process

1.- Calculate the molar mass of Water

Molar mass = (2 x 1) + (1 x 16)

= 2 + 16

= 18 g

2.- Use proportions to find the number of particles. Use Avogadro's number.

18 g ---------------- 6.023 x 10²³ particles

546 g --------------- x

x = (546 x 6.023 x 10²³) / 18

3.- Simplification

x = 3.289 x 10²⁶ / 18

4.- Result

x = 1.83 x 10²⁵ particles

A sample of seawater has 0.075 g of sodium chloride per mL of solution. How many moles of sodium chloride are there per liter of

amm1812

Answer:

1.28 mol

Explanation:

mole = mass/molar mass

n = v/v/cm³

mass = 0. 075g

v = 1dm³ =1000cm³

n= m/MV=0.075/58.44(1000)

n =1.28 mol
