The charge of Fe in Fe₂O₃ is +3.

Let's consider the equation for the thermite reaction:

Fe₂O₃ + 2 Al ⇒ Al₂O₃ + 2 Fe

One of the reactants is ferric oxide, we can calculate the charge of Fe in Fe₂O₃ considering that:

  • The sum of the charges of the atoms is equal to the charge of the compound.
  • The charge of a neutral compound is 0.
  • The charge of O in oxides is -2.

The charge of Fe in Fe₂O₃ is:

2Fe+3O = 0\\2Fe+3(-2)= 0\\Fe=+3

The charge of Fe in Fe₂O₃ is +3.

Photosynthesis occurs in both prokaryotes and eukaryotes.How do the location where photosynthesis occurs differ in prokaryotes a
tamaranim1 [39]

Answer:

In eukaryotes, it occurs in the chloroplast. In prokaryotes it does it in the cytoplasm.

Explanation:

Prokaryotes don't have organelles such as the mitochondria and the chloroplast, it just has cell membrane, which its only function is to protect the cell and is unable to generate chemical processes; the DNA, which stores and manages only the genes, which would be affected if exposed to a chemical process like photosynthesis; and the cytoplasm, which stores the materials that the cell needs, where photosynthesis occurs. Eukaryotes have chloroplasts, which absorb the sunlight and combine it with carbon dioxide and water to realize photosynthesis.

In the human brain, a great deal of synaptic pruning occurs in early childhood. This pruning appears to be:_______.
Alex

Answer: D. An adaptive process that allows children to deal more efficiently with their environment.

Explanation:

Synaptic pruning is a natural process between early childhood and adulthood which occurs in the brain. The brain removes the extra synapses during synaptic pruning. Synapses are brain structures that allow the neurons to transmit to another neuron an electrical or chemical signal.  

Synaptic pruning is thought to help the brain transition from adolescence, when it can quickly learn and make new connections, to adulthood, when it is much more stable in its structure, but can concentrate on a single question for longer and conduct more complex thinking processes. Synaptic pruning make brain more adaptive to the external environment in early ages.

Hence, the correct option is D. An adaptive process that allows children to deal more efficiently with their environment.
