Answer:

This can be proved by the following activity: Take some Iron fillings and dip them in the Copper sulphate solution. After some time you will notice that there is a colour change in the solution which is caused due to the displacement of Copper from it solution.

Answer:

D) One half of the carbon atoms of newly synthesized acetyl CoA.

Explanation:

It will be radioactively labeled because Malonyl CoA which contains 3 Carbon molecule is synthesized from Acetyl CoA which has 2 Carbon molecule.

This happens with the addition of ‘CO2’ with the help of the enzyme called acetyl CoA carboxylase.

2.67 grams of butane (C4H10) is combusted in a bomb calorimeter. The temperature increases from 25.68 C to 36.2C. What is the ch
slavikrds [6]

The internal energy : 1310.43 kJ/mol

<h3>Further  explanation</h3>

Internal energy (ΔE) can be formulated for Calorimeter :

\tt \Delta E=C\times.\Delta t

C= the heat capacity of the calorimeter

Δt=36.2-25.68=10.52°C

\tt \Delta E=5.73 kJ/^oC\times 10.52^oC=60.2796~kJ

  • mol butane(MW=58,12 g/mol)

\tt \dfrac{2.67}{58,12 }=0.046

  • the internal energy (ΔE) in KJ/mol

\tt \dfrac{60.2796}{0.046}=1310.43~kJ/mol

irina1246 [14]

The question is incomplete, the complete question is;

A magnet was placed near a pile that contained both iron and sulfur. The magnet was moved gradually closer to the pile. As it neared the pile, the magnet started attracting small pieces of iron from the pile. Which of these statements best describes the contents of the pile?

F. It is a homogeneous mixture of iron and sulfur.   G. It is a heterogeneous mixture of iron and sulfur.   H. It is a compound that contains both iron and sulfur.   I. It is a compound that can be separated by magnetism.

Answer:

G. It is a heterogeneous mixture of iron and sulfur.

Explanation:

A heterogeneous  mixture is one that does not have a uniform composition throughout.

We must recall that a mixture is any combination of substances that do not chemically react together and are separable by physical means.

Having said this, it is clear that I can separate the iron from sulphur by simple magnetic (physical) means. Hence,  it is a heterogeneous mixture of iron and sulfur.
