Answer:
The Phases of Matter are Solid, Liquid, and Gas. With Plasma as an exception. Solids are defined by their structural stiffness and resistance to form or volume changes. A liquid is a compressible fluid is one that adapts to the geometry of its container while maintaining a consistent volume regardless of pressure. Gas compresses easily, expands to fill containers, and takes up significantly more space than the liquids or solids from which it is formed. Plasma has no fixed shape or solid volume just like gas. That's the best I can explain, hope you find it helpful!
Explanation:
First you need to find the number of moles there are in 89g of Mg(NO₃)₂ . To do this, divide the 89g by the molar mass of magnesium nitrate (148.3g/mol) to get 0.6mol of magnesium nitrate. Then to find the volume of solution that contains 0.6 moles you need to divide 0.6mol by 0.40M to get 1.5L of solution.
I hope this helps. Let me know in the comments if anything is unclear.
The answer is: A; Free Energy
Answer:
Photosynthesis
Explanation:
Plants use the energy they get from the sun, take in water from the roots, and take in carbon dioxide from the air to make glucose. AKA their food.
