Ethene will not typically react with hydrogen gas through simple bimolecular collisions. Using the picture, explain how this rea

ction becomes possible.
A: A metal surface is catalyzing the reaction by speeding up the kinetic energy of hydrogen gas and, as a result, breaking its bonds so that it can react with ethene.

B: A metal surface is acting as a catalyst and lowers the activation energy of bond breaking of hydrogen gas.

C: Ethene is stabilized by a metal surface and hydrogen gas catalyzes the metal surface so that it can react with ethene.

D: Ethene is catalyzed by a metal surface and, therefore, raises the activation energy of hydrogen gas breaking apart.

When a solid compound is formed from chemicals which are in solution, it is called a?
SVETLANKA909090 [29]

Answer: precipitate.


Explanation:


1) When the product of the reaction between the chemicals in the solution is insoluble, then it cannot remain in the solution and it will precipiate, forming a solid substance.


2) That happens, for example, when you have two solutions with different solutes, mix them together, the solutes can react chemically with each other, yielding a product that is insoluble.


3) A typical example of such kind of precipitation reactions is athe neutralization of an acid and a base.


Acid + Base = salt + water


If the salt is insoluble in water then it will form a a precipitate (solid), if the product is soluble in water then it remains as an aqueos ions in the solution.

Fiesta28 [93]

Answer:

The correct option is: a. Photosphere

Explanation:

Sun is the brightest star in the sky of our planet Earth and the principle component of the Solar System. It is a <u>gaseous object</u> that is made up of hot plasma and contributes 99.86% to the total mass of our Solar System.

<u>The Sun does not have a clearly defined surface.</u> The <u>visible surface of the Sun is known as the Photosphere</u>, which is the deepest visible portion of the Sun.

N2 + 3 H2 --&gt; 2 NH3
Anna71 [15]

Answer:

4 moles of NH3 will be produced

Explanation:

The reaction expression is given as:

            N₂  +  3H₂  →  2NH₃

We have to check that the equation of the reaction is balanced.

 Then;

      if 2 mole of N₂ reacts;

 1 mole of N₂ will react with 3 mole of H₂ to produce 2 mole of NH₃

2 mole of N₂ will react with (2x3)mole of H₂ to produce (2x2)mole of NH₃

                                                    6mole of H₂ to produce      4 mole of NH₃

Which of the solutions have greatest osmotic pressure 30% sucrose 60% sucrose or 30% magnesium sulfate?
timofeeve [1]

Answer:Osmotic pressure is the minimum amount of pressure a solution must exert in order to prevent from crossing a barrier by osmosis. Solute molecules have difficulty crossing semipermeable membranes, so the more solutes that are in a solution, the higher the osmotic pressure will be. Between 30% sucrose and 60% sucrose, 60% sucrose will have a greater osmotic pressure than 30% because it has a higher percentage of solutes. However, since sucrose has a higher potential to cross semipermeable membranes and is more absorbable than magnesium sulfate, magnesium sulfate would have a higher osmotic pressure than 60% sucrose even though 60% sucrose has higher molecules.
