A) fixed volume and fixed shape- Solid. b)fixed volume variable shape- Volume. c) variable volume variable shape- Gas. D) state in which molecules move the most- Solids E) molecules move the least- Gas. F) A phase change is a physical change in matter. G) Melting- becoming liquified by heat. H) Freezing- a liquid turned into a solid by extreme cold. I) Vaporizing- when a liquid changes form into a gas. J) Condensing- to change from a gas or vapor to a liquid. K) Sublimation- goes directly from a solid state to a gas state. (Dry ice). J) Deposition- a geological process in which sediments, solids and rock are added to landforms or landmass by transport of wind, water, gravity or weather. K) sublimation is an increase in energy. L) freezing is a decrease in energy
2Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂
First equation: A. Combustion
Second equation: C. Decomposition
Third equation: E. Double Replacement
Fourth equation: D. Single Replacement
Fifth equation: B. Synthesis
We place a burning splint at the mouth of the test tube and listen for a pop sound. It occurs because Hydrogen gas is explosive. The third option is correct.
4 because it's electron configuration is 1s2 2s2 2p2 and to have a full outer valence shell you need 2p6 so you only need 4 more electrons to get to 2p6.
Nedd this too please helpppp
Answer:
13,2 %.
Explanation:
Overall yield = 0.55 * 0.24
= 0.132
= 13,2 %.
