The characteristics of two different types of reactions are shown below: Reaction A: Electrons are gained by the atoms of an ele

ment. Reaction B: Protons are lost by the atom of an element. Which statement is true about the atoms of the elements that participate in the two reactions? (5 points) Their identity changes in both Reaction A and Reaction B. Their identity changes in Reaction A but not in Reaction B. Their identity changes in Reaction B but not in Reaction A. Their identity remains the same in both Reaction A and Reaction B.

Answer:

Their identity changes in Reaction B but not in Reaction A.

Explanation:

Reaction A describes a chemical reaction. Chemical reactions change the structures of substances and cause a gain or loss of electrons. Gaining or losing electrons will not change the identity of an atom.

Reaction B describes a nuclear reaction, which either splits the nucleus apart or combines two smaller nuclear.  Nuclear reactions cause a gain or loss of protons and neutrons by the atom of an element, thereby changing its identity.

pentagon [3]

Answer:

I would write "terrestrial/lives on land during all life stages" between the frog and pigeon branches

Explanation:

Jaw evolution has started with fish, so i'd place that before the perch, evolution of four limbs is next and I would plate it between the perch and the frog. Evolution of an egg has ensured that organisms remain terrestrial during all stages of life and don't need to rely on water to lay their eggs. So I would place that between the frog and the pigeon. True mammary glands and true hair, as we know it formed on mammals so i'd place that between the pigeon and the rats (although synapsids evolved similar structures long before birds even existed). And lastly, I would place "walking on two legs" between rats and human branches. Because our ancestors evolved bipedalism relatively late.

The Al2O3 crystal structure (corundum) consists of an HCP arrangement of O2- ions; the Al3 ions occupy octahedral positions. Wha
ddd [48]

Answer:

2/3

Explanation:

Crystals structures can also be seen when two elements combines together and the perfect example is Al₂O₃ which is given in the question above. Just like it is given in the question above, the kind of arrangement in the crystal structure for Al₂O₃ is called HCP which stands for Hexagonally Closed Pack.

The aluminum ions which is in form of Al³⁺ occupies the two-third[2/3] positions while the position that the oxygen ion occupies is one[1].
