HELPPPPP NEED FOR ESSAY Vicente is going to spend the afternoon in his yard. He has the choice to get in the pool, lay on a cott

on chaise longue, sit on the porcelain tile bordering the pool, or sit on a plastic chair. The specific heats of these items are: Water = 4.19 J/g•°C Cotton = 1.30 J/g•°C Porcelain = 1.07 J/g•°C Plastic = 1.67 J/g•°C Based on the specific heat values given, where is the coolest location for Vicente to be?

<h2>Answer : Option A) Water = 4.19 J/g.°C</h2><h3>Explanation :</h3>

According to the given option the coolest location for Vicente will be the pool. As higher is the value of the specific heat of the item/material lower will be the heating rate of that item/material.

So, when comparing the given options, water seems to be higher in specific heat compared to others. This clearly indicates that it will be the coolest location for Vicente to spend his afternoon.

The higher the specific heat, the longer it will take to get hot. The coolest location for Vicente to be would be the water, because its specific heat is higher than the other locations.

maxonik [38]

Answer: The 234.74 grams of sample should be ordered.

Explanation:

Let the gram of  114 Ag to ordered be N_o

The amount required for the beginning of experiment = 0.0575 g

Time requires to ship the sample = 4.2hour = 252 min(1 hr = 60 min)

Half life of the sample ={t_{\frac{1}{2}} = 21 min

\lambda =\frac{0.693}{t_{\frac{1}{2}}}=\frac{0.693}{21 min}=0.033 min^{-1}

\log[N]=\log[N_o]-\frac{\lambda t}{2.303}

\log[0.0575 g]=\log[N_o]-\frac{0.033 min^{-1}\times 252 min}{2.303}

N_o=234.74 grams

The 234.74 grams of sample should be ordered.

fills a 500.mL flask with 3.6atm of carbon monoxide gas and 1.2atm of water vapor. When the mixture has come to equilibrium she
enot [183]

Answer:

The answer to the question is

The pressure of carbon dioxide after equilibrium is reached the second time is 0.27 atm rounded to 2 significant digits

Explanation:

To solve the question, we note that the mole ratio of the constituent is proportional to their partial pressure

At the first trial the mixture contains

3.6 atm CO

1.2 atm H₂O (g)

Total pressure = 3.6+1.2= 4.8 atm

which gives

3.36 atm CO

0.96 atm H₂O (g)

0.24 atm H₂ (g)

That is

CO+H₂O→CO(g)+H₂ (g)

therefore the mixture contained

0.24 atm CO₂ and the total pressure =

3.36+0.96+0.24+0.24 = 4.8 atm

when an extra 1.8 atm of CO is added we get Increase in the mole fraction of CO we have one mole of CO produces one mole of H₂

At equilibrium we have 0.24*0.24/(3.36*0.96) = 0.017857

adding 1.8 atm CO gives 4.46 atm hence we have

 (0.24+x)(0.24+x)/(4.46-x)(0.96-x) = 0.017857

which gives x = 0.031 atm or x = -0.6183 atm

Dealing with only the positive values we have the pressure of carbon dioxide = 0.24+0.03 = 0.27 atm
