A vial is filled with room temperature water, and blue cold water has been placed at the bottom. A warm water bag sits next to t
MrRa [10]

Explanation:

In the context, a vial which is used in store medical samples is filled with water at room temperature. And the vial is kept on a cold water. Also a water bag containing warm water is kept near the vial.

The cold water kept at the bottom of the vial is having lower kinetic energy while warm water will have higher kinetic energy than the others. Since the water in the vial is at room temperature and it is in touch with the cold blue water, the water in the vial will loose or give its temperature to the cold blue water through conduction as well as convection process since temperature always flows from a hot body towards the cold body.

On the other hand, the warm water placed next tot he vial will give its temperature to the atmosphere.

Calculate the molecular weight of freon-12, if 122.70 liters of its vapor at 200.00
ICE Princess25 [194]

PV = nRT

Where:


P = pressure in atm = 700/760 = 0.9211atm


V = volume = 8.29L


R = gas constant, 0.08206 atm-L/mol-K


T = temperature in Kelvin = 200 + 273 = 473


n = numbers of moles  = Mass/molar mass


mass of the compound = 30.5


we can rewrite the equation above as


PV = (Mass)/(Molar mass) * RT

CAN SOMEONE PLEASE ANSWER THIS PAGE ILL GIVE YOU ALL MY POINTS
iris [78.8K]

Answer: the equation for the reaction is NH4Cl (s) --> NH3 (g) + HCl (g)

equation for heat reaction:

ΔH25° = (ΔH25° NH3 + ΔH25° HCl) - ΔH25° NH4Cl)

question 2:

the 1st and 3rd reactions are better ontained through  refrence sources and the 2nd and 4th are the easiest and safest to measure in the laboratory. The 1st and rd reaction contains noxious gases this is because there is a (g) in both of the reactions. And the 2nd and 4th does NOT contain noxious gases so i assume its the safest to measure out in the lab

Gaseous ethane CH3CH3 will react with gaseous oxygen O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. Suppose 0.6
yulyashka [42]

Answer:

1.8 g

Explanation:

Step 1: Write the balanced equation

CH₃CH₃(g) + 3.5 O₂(g) ⇒ 2 CO₂(g) + 3 H₂O(g)

Step 2: Determine the limiting reactant

The theoretical mass ratio of CH₃CH₃ to O₂ is 30.06:112.0 = 0.2684:1.

The experimental mass ratio of CH₃CH₃ to O₂ is 0.60:3.52 = 0.17:1.

Thus, the limiting reactant is CH₃CH₃

Step 3: Calculate the mass of CO₂ produced

The theoretical mass ratio of CH₃CH₃ to O₂ is 30.06:88.02.

0.60 g CH₃CH₃ × 88.02 g CO₂/30.06 g CH₃CH₃ = 1.8 g
