C.  Single-replacement

D.  Decomposition

Explanation:

A:  Synthesis.  Two reactants are combined to form, or synthesize, one product.

B:  Combustion.  This is the general reaction for combustion.  When something combusts, oxygen must be present.  Carbon dioxide and water must also be produced.

C:  Single-replacement. The oxygen from Fe₂O₃ is moved to K to form K₂O.  Only one thing is being moved, or replaced.

D:  Decomposition.  You have one compound that breaks into, or decomposes, into two products.

Diffusion of Ammonia in an Aqueous Solution. An ammonia (A)-water (B) solution at 278 K and 4.0 mm thick is in contact at one surface with an organic liquid at this interface. The concentration of ammonia in the organic phase is held constant and is such that the equilibrium concentration of ammonia in the water at this surface is 2.0 wt 'Yo ammonia (density of aqueous solution is 991.7 kg/m3) and the concentration of ammonia in water at the other end of the film 4.0 mm away is 10 wt % (density of 961.7 kg/m3). Water and the organic are insoluble in each other. The diffusion coefficient ofNH3 in water is 1.24 x 10- 9 m 2/sCalculate the flux N_B. Explain.

Answers

Answer:

The Flux N_B = 0

Explanation:

So, we are given the following set of data or parameters which is going to help in solving this particular Question. So, let us take each at a time;

=> "An ammonia (A)-water (B) solution at 278 K and 4.0 mm thick is in contact at one surface with an organic liquid at this interface."

=>" 2.0 wt 'Yo ammonia (density of aqueous solution is 991.7 kg/m3) and the concentration of ammonia in water at the other end of the film 4.0 mm away is 10 wt % (density of 961.7 kg/m3). ''

With the information above, we can determine the N_A(which the question did not specify that we should calculate).

For the value of N_B, it will be equals to zero(0) because the insolubility of water in organic solvent.

Can someone please help me

Answers

I think the answer would be A because O is oxygen and it has 7. Although it’s in parentheses and has a 2 on the outside of those parentheses, so you would multiply and 7 x 2 = 14. 14 is larger than the other ones.

How many moles of gold, a U, are in 3.60×10^-5 G of gold?

Answers

Answer:

See Below.

Explanation:

This is a conversion problem:

Using the molar mass of Gold (given in a periodic table) which is 196.97g/mol

you have

[tex](3.60*10^-5 g) *\frac{1moles}{196.97g}[/tex]

you always arrange the equation in a way to cancel whatever you don't want (grams) and leave what you do want (moles). Here grams cancel (top and bottom), so you're left with:

[tex]\frac{(3.60*10^-5 g) *(1)}{196.97} = 1.83*10^-7[/tex] moles of Gold

A.

B.

C.

D.

Answers

Answer:

B.  thermal conductivity

Explanation:

They physical property being tested during the fourth step is the thermal conductivity of the materials.

Thermal conductivity is the ability of a body to transmit heat energy from one place to another.

Since we are measuring how long it takes for heat from the hot plate to reach the wax ball, this is a typical experiment for measuring thermal conductivity. Most metals are good conductors and heat energy moves fast in them.Non-metals are poor conductors with low thermal conductivity.

How many moles are in 5.25 X 10 25
atoms of Au?

Answers

Answer:

The answer is 87.21 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\ [/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{5.25 \times {10}^{25} }{6.02 \times {10}^{23} } \\ = 87.2093023...[/tex]

We have the final answer as

87.21 moles
