A que temperatura se produce el punto de fusión

Chemistry
1 answer:
Sholpan [36]3 years ago
6 0

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.

A 0.1946 g piece of magnesium metal is burned in a constant-volume calorimeter that has a heat capacity for the bomb only of 134
Phoenix [80]

Answer:

The heat of combustion of magnesium metal is 24.76 kJ/gram

Explanation:

Step 1: Data given

Mass of magnesium sample = 0.1946 grams

Molar mass of magnesium = 24.3 g/mol

bomb calorimeter that has a heat capacity of 1349 J/°C

Mass of water = 500 grams

Temperature change = 1.40 °C

Step 2: Calculated heat released

Q = (1349 J/°C * 1.40 °C) + (500 grams * 4.184 J/g°C * 1.40 °C)

Q =4817.4 J = 4.82 kJ

Step 3: Calculate the heat given off by the burning Mg, in kJ/g

4817.4 J / 0.1946 grams = 24755.4 J/ gram = 24.76 kJ/ gram

The heat of combustion of magnesium metal is 24.76 kJ/gram
