Diagram 1 exhibits the nature of the particles within the state that forms after a solid melts. Solids melt into liquids and the particles within a liquid have a greater spacing than the particles in a solid. Moreover, these particles are free to slip over one another, which means that liquids do not have a definite shape; however, the particles are still confined in by intermolecular forces, which means that the volume of a liquid is definite.

Answer: Diagram 1 (with the blue balls).

Explanation:

1) After the solids melt they are liquids.

Liquid state is characterized by the particles being close but yet free to move, they can slip over each other, which is what permit the liquids flow and take the shape of the containter.

2) Solid is the state of the matter in which the particles are stuck together, they cannot move with respect to the others, but they are in fixed positions. In this state the particles vibrate and the matter has a definite shape and volume.

This state is represented by the diagram 3 (the red balls).

3) In gas state the particles are quite separated, free to move in and occupy all the space. In this state the particles are moving at great speed. The volume of the gas is the volumen of the container.

This state is represented by the diagram 2(the yellow balls).

4) Plasma is the state of the matter similar to gas state but the particles are ions. Those are particles that have charge, either positive or negative.

This is represented by the diagram 4 (the balls with positive and negative symbols).

Consider the following mechanism for the reaction between nitric oxide and ozone:

swat32

Answer:

A . 2 O₃(g) + 2 NO ⇒ 2 O₂ (g) + 2 NO₂(g)

B . Yes

C. O and NO₃

Explanation:

A. The overall reaction is obtained by adding the individual steps in the reaction mechanism where we will get the reactants and product and the intermediates will cancel.

Thus, adding 1+ 2 +3 we get

2 O₃(g) + 2 NO ⇒ 2 O₂ (g) + 2 NO₂(g)

B. The reaction intermediates are those that are produced from the initial and/or subsequent steps and are consumed later on in the reaction mechanism, but are neither reactants nor products, they just participate.

From this definition it follows that O(g) and NO₃ are reaction intermediates.

C. O and NO₃

BRAINLIESTTT ASAP!!! PLEASE HELP ME :)

Leno4ka [110]

Answer:

"Thermometer C, because it measures accurately in the ones place."

Explanation:

Thermometer D measures using tens place. Since we are measuring the liquid's temperature at 47 degrees Celsius, the most appropriate thermometer would measure in ones place, not tens place.

Hope this helps! :)

How do nuclear fusion and combustion relate?

RUDIKE [14]

Answer:The key to remember is that carbon combustion requires oxygen. As soon as there is no oxygen left, carbon combustion stops. In nuclear fusion, the nuclei of atoms are fused together to make new, bigger nuclei.

Why doesnt iron burst into flames when it rusts

Katarina [22]

Rust does not have the properties to catch onto flames. However, if you light it on fire, then it would probably catch in flames but not instantly and will not continue to burn unless you have soaked it in oil or flammable object or substance. :) Hope this helps!
