<h3><u>Answer;</u></h3>

Carbon

<h3><u>Explanation;</u></h3>

In the cores of extremely hot red giants, nuclear reactions convert helium to <u>carbon</u>.

  • A red giant star is a dying star in the last stages of stellar evolution. In the main sequence stage stars convert hydrogen into helium through nuclear fusion.
  • As stars in the main sequence stage slowly converts their core from hydrogen to helium the fusion continues to create a shell and soon the Helium core begins to shrink, and visible of the star change. The star becomes a red giant.
  • <em><u>In the red giant core the nuclear reactions convert helium into carbon. This happens when the temperature reaches 100 million K, and the nuclear fusion of He to Carbon begins, creating carbon and releasing energy.</u></em>

Which macromolecules break apart by hydrolysis?
ankoles [38]

Answer:

Dehydration synthesis reactions build molecules up and generally require energy, while hydrolysis reactions break molecules down and generally release energy. Carbohydrates, proteins, and nucleic acids are built up and broken down via these types of reactions, although the monomers involved are different in each case.

At 500 K the reaction 2 NO(g) + Cl2(g) ⇌ 2 NOCl(g) has Kp = 51 In an equilibrium mixture at 500 K, the partial pressure of NO is
Aleks [24]

Answer:

p3=0.36atm (partial pressure of NOCl)

Explanation:

2 NO(g) + Cl2(g) ⇌ 2 NOCl(g)  Kp = 51

lets assume the partial pressure of NO,Cl2 , and NOCl at eequilibrium are P1 , P2,and P3 respectively

Kp=\frac{[NOCl]^{2} }{[NO]^{2} [Cl_2] }

Kp=\frac{[p3]^{2} }{[p1]^{2} [p2] }

p1=0.125atm;

p2=0.165atm;

p3=?

Kp=51;

On solving;

p3=0.36atm (partial pressure of NOCl)

Stells [14]

Answer:

Electric Current

This is a flow of electrons (such as the flow of electrons in a wire to light up a lamp).

Insulator

These stop the electricity from flowing (think rubber and glass).

Resistance

This is slowing the flow of electrons (the current) and where some of the electrons' energy gets converted into heat.

Conductor

These allow electricity to flow easily through them (think copper and aluminum).
