Answer:
combining 2 grams of copper and 4 grams of sulfur to make 6 grams of copper sulfate
Explanation:
The Law of Conservation of Mass states that matter cannot be created or destroyed in chemical reactions. It posits that the mass of a substance remains unchanged after undergoing a chemical process.
Therefore, according to the question, the procedure that best demonstrates the law of conservation of mass after the chemistry student conducted different procedures is option D.
This is because, the mass of copper and sulfate did not change but merely combined to form a compound.
When convergent happens:
•Deep ocean trenches
• volcanoes
• mountains
• earthquakes
When divergent occurs:
• new oceanic crust forms
• submarine mountain range
• volcanoes
• earthquakes
When transform occurs:
• faults
• earthquakes
• linear valleys
• stream beds split in half
The answer is 1815.15 mm hg
Answer:
2. Volcanoes
Explanation:
The interior of some planets (e.g earth) contains some hot flowing fluids called lava which has a very high thermal energy. The lava as a means of escaping the confinement within the planet, burst out by creating an opening through the ground to the surface of the planet to release the energy (lava).
This process in which the energy is released to the surface of the planet is termed volcanic eruptions. Which occurs majorly in some susceptible regions of the earth.
The openings in the ground that release energy from deep inside the planet is thus called volcanoes.
