A que temperatura se produce el punto de fusión

Chemistry
1 answer:
Sholpan [36]3 years ago

Answer:

<h2>32°F /0°C </h2>

Explanation:

At what temperature does the melting point occur?

32°F /0°C

(32°F − 32) × 5/9 = 0°C

At temperatures above 32°F (0°C), pure water ice melts and changes state from a solid to a liquid (water); 32°F (0°C) is the melting point. For most substances, the melting and freezing points are about the same temperature.

Is Melting Point affected by temperature?

Melting point, the temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change.

In the reaction 2Mg (s) + O2 (g) + 2H2O (l) → 2Mg2+ (aq) + 4OH– (aq), which substance is reduced?
Bogdan [553]

F. <em>None of the above </em>

<em>No O atoms are present</em> as reacting substances, only O_2 and H_2O molecules.

O_2 + 2H_2O + 2e^(-) → 4OH^(-)

We must use <em>oxidation numbers</em> to decide whether oxygen or water is the substance reduced.

The oxidation number of O changes from 0 in O_2 to -2 in OH^(-).

A decrease in oxidation number is <em>reduction</em>, so O_2 is the substance  reduced.

The oxidation number of O is -2 in both H_2O and OH^(-), so water is <em>neither oxidized nor reduced</em>.

What are the rules for calculating protons
Mashcka [7]

Answer:

Find the element,

Explanation:

Finding the element will tell you how many protons there are. For example, if you are given an atom of oxygen, you can figure out the number of protons by looking it up on a periodic table, which gives you 8.

If an atom is neutral, find the number of electrons. This number will also be the number of protons.
