If you combine 230.0 mL of water at 25.00 ∘ C and 140.0 mL of water at 95.00 ∘ C, what is the final temperature of the mixture?
IgorLugansk [536]

<u>Answer:</u> The final temperature of the mixture is 51.49°C

<u>Explanation:</u>

When two samples of water are mixed, the heat released by the water at high temperature will be equal to the amount of heat absorbed by water at low temperature

Heat_{\text{absorbed}}=Heat_{\text{released}}

The equation used to calculate heat released or absorbed follows:

Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})

m_1\times c\times (T_{final}-T_1)=-[m_2\times c_2\times (T_{final}-T_2)]       ......(1)

where,

q = heat absorbed or released

m_1 = mass of water at high temperature = 140 g     (Density of water = 1.00 g/mL)

m_2 = mass of water at low temperature = 230 g

T_{final} = final temperature = ?°C

T_1 = initial temperature of water at high temperature = 95.00°C

T_2 = initial temperature of water at low temperature = 25.00°C

c = specific heat of water= 4.186 J/g°C

Putting values in equation 1, we get:

140\times 4.186\times (T_{final}-95)=-[230\times 4.186\times (T_{final}-25)]

T_{final}=51.49^oC

Hence, the final temperature of the mixture is 51.49°C

A 10.0 L flask at 318 K contains a mixture of Ar and CH4 with a total pressure of 1.040 atm. If the mole fraction of Ar is 0.715
andrey2020 [161]

Answer:

w_{Ar}=0.814

Explanation:

Hello,

In this case, given the temperature, volume and total pressure, we can compute the total moles by using the ideal gas equation:

PV=nRT\\\\n=\frac{PV}{RT}=\frac{1.040atm*10.0L}{0.082\frac{atm*L}{mol*K}*318K}\\  \\n=0.41mol

Next, using the molar fraction of argon, we compute the moles of argon:

n_{Ar}=0.41mol*0.715=0.29mol

And the moles of methane:

n_{CH_4}=0.41mol-0.29mol=0.12mol

Now, by using the molar masses of both argon and methane, we can compute the mass percent of argon:

w_{Ar}=\frac{m_{Ar}}{m_{Ar}+m_{CH_4}}=\frac{0.29mol*\frac{40g}{1mol}  }{0.29mol*\frac{40g}{1mol}+0.12mol*\frac{16g}{1mol}}  \\\\w_{Ar}=0.814

Regards.

I have 26 protons,26 electrons, and 30 neutrons?
Amiraneli [1.4K]

Answer:

Iron (Fe)

Explanation:

# of protons is the atomic number of the element

the element with the atomic number 26 is Iron

with 26 electrons this means it is Iron with no charge

with 30 neutrons this means the atomic weight will be

26 (protons) + 30 (neutrons) = 56

the real atomic weight of iron listed on the periodic table is 55.845, this rounded up is 56.

The strongest intermolecular interactions between propanol (CH3CH2CH2OH) molecules arise from hydrogen bonding
pickupchik [31]

The claim that the strongest intermolecular interactions between propanol molecules arises from hydrogen bonding is True.

Intermolecular forces are weaker attraction forces that are utilized to define physical characteristics of molecules such as:

  • boiling point
  • temperature
  • density
  • melting points

Hydrogen bonding is an type of intermolecular forces.

It is a type of dipole-dipole interaction that only happens when a hydrogen atom is connected to the atomic element of oxygen, nitrogen, or fluorine.

From the question given, in the propanol (CH3CH2CH2OH) molecule, the hydrogen usually has a partially positive charge which attracts the partially negative charge of the oxygen.

Therefore, we can conclude that the claim is True.
