Saturated steam at 1 atm condenses on a vertical
plate that is maintained at 90°C by circulating cooling water
through the other side. If the rate of heat transfer by condensation
to the plate is 180 kJ/s, determine the rate at which the
condensate drips off the plate at the bottom.

Answers

Answer 1

The rate at which the condensate drips off the plate at the bottom is 597 g/s.

The rate of heat transfer by condensation to the plate is given as 180 kJ/s.

We can use the heat transfer equation to determine the rate at which the condensate drips off the plate. The heat transfer equation is;

Q = m([tex]L_{f}[/tex] + CpΔT)

Where Q is heat transferred, m is mass of the condensate, Lf is the latent heat of fusion, Cp is specific heat of the condensate, and ΔT is  temperature difference between the condensate and the plate.

At the point of condensation, the steam is at its saturation temperature of 100°C. The condensate will be at the same temperature as the plate, which is 90°C.

The latent heat of fusion for water is 2257 kJ/kg, and the specific heat of water is 4.18 kJ/kg-K.

To find the mass of the condensate, we need to use the steam tables. At 1 atm, the specific volume of saturated steam is 1.672 m³/kg. The volume of steam that condenses on the plate can be found by assuming that it is a thin film and using the surface area of the plate. Let's assume that the plate has a surface area of 1 m². Then the mass of the condensate is;

m = (1 m²) / (1.672 m³/kg) = 0.597 kg

Now we can plug in the values into the heat transfer equation:

180 kJ/s = (0.597 kg)(2257 kJ/kg + 4.18 kJ/kg-K(100°C - 90°C))

Solving for the rate at which the condensate drips off the plate, we get:

m = 0.597 kg/s = 597 g/s

Therefore, the rate is 597 g/s.

balance Ca(NO3)2 + NaCl ---> NaNO3 + CaCl2

Answers

Answer:

Ca(NO3)2 + 2 NaCl = 2 NaNO3 + CaCl2

Explanation:

On the left you have an original balance of Ca - 1, N - 2, O - 6, Na - 1, and Cl - 2, and on the right you have a balance of Ca - 1, N - 1, O - 3, Na - 1, Cl - 2.

Ca - 1 Ca - 1

N - 2 N - 1

O - 6 O - 3

Na - 1 Na - 1

Cl - 1 Cl - 2

In order to balance these, you'll have to make both sides equal. To get the N on the right to be equal to the N on the left, you'll have to multiply NaNO3 by 2, thus making it 2NaNO3. By doing this, you will offset the balance of both Na and O.

Ca - 1 Ca - 1

N - 2 N - 2

O - 6 O - 6

Na - 1 Na - 2

Cl - 1 Cl - 2

To balance the rest of the equation, you'll have to multiply both Na and Cl by 2. This will change NaCl to 2NaCl, making the balance look like this:

Ca - 1 Ca - 1

N - 2 N - 2

O - 6 O - 6

Na - 2 Na - 2

Cl - 2 Cl - 2

You will now be left with your final equation Ca(NO3)2 + 2 NaCl = 2 NaNO3 + CaCl2.

How many mL of a 1.00 M HCl solution would need to be added to 100 mL of 0.263 M ammonia to produce a buffer with a pH of 10.00. The pKa of ammonia is 9.25.

Answers

Answer:

3.97mL of 1.00M HCl must be added

Explanation:

The buffer of ammonia and ammonium ion follows the equation:

pH = pKa + log [NH₃] / [NH₄⁺] (1)

Where pH is the pH we want to obtain: 10.00

pKa is the pKa of the buffer: 9.25

[NH₃] could be taken as moles of ammonia

And NH₄⁺ moles of ammonium ion

When NH₃ reacts with HCl:

NH₃ + HCl → NH₄⁺ + Cl⁻

NH₄⁺ is produced. That means moles of ammonia are Initial moles of ammonia - Moles of HCl added

Moles of HCl added = Moles of ammonium ion

The total moles of the buffer are:

0.100L * (0.263mol / L) = 0.0263moles = [NH₄⁺] + [NH₃] (2)

Rewriting (1):

10.00 = 9.25 + log [NH₃] / [NH₄⁺]

0.75 = log [NH₃] / [NH₄⁺]

Replacing (2) in (1):

0.75 = log 0.0263 -  [NH₄⁺] / [NH₄⁺]

5.6234 = 0.0263 -  [NH₄⁺] / [NH₄⁺]

5.6234[NH₄⁺] = 0.0263 - [NH₄⁺]

6.6234[NH₄⁺] = 0.0263

[NH₄⁺] = 0.00397 moles = Moles HCl

To obtain these moles we must add:

0.00397 moles HCl * (1L / mol) = 0.00397L =

3.97mL of 1.00M HCl must be added

explain why a nanowire can be longer than 3000nm but still be considered a metallic nanomaterial​

Answers

Answer:

A nanowire is a nanostructure, with the diameter of the order of a nanometre (10−9 meters). It can also be defined as the ratio of the length to width being greater than 1000. Alternatively, nanowires can be defined as structures that have a thickness or diameter constrained to tens of nanometers or less and an unconstrained length. At these scales, quantum mechanical effects are important—which coined the term "quantum wires". Many different types of nanowires exist, including superconducting (e.g. YBCO[1]), metallic (e.g. Ni, Pt, Au, Ag), semiconducting (e.g. silicon nanowires (SiNWs), InP, GaN) and insulating (e.g. SiO2, TiO2). Molecular nanowires are composed of repeating molecular units either organic (e.g. DNA) or inorganic (e.g. Mo6S9−xIx).

How many carbon atoms are there in a 12.5 kg sample of carbon?
step by step solution

Answers

Answer:

6.27 X 10^26 atoms

Explanation:

Write down the formula:

number of moles = mass/Ar    (Ar is atomic mass)

Ar of carbon = 12

mass = 12.5kg or 12500g

Substitue these values into the formula:

number of moles = 12,500g / 12 = 3125/3 or 1041.6

Convert this to atoms:

1 mole = 6.022 X 10^23 atoms

So, 1041.6 moles = 6.27 X 10^26 atoms
