Answer:
Explanation:
We know that protons and electrons are equal to one another, in a normal atom. This can be found by looking at the elements atomic number, oxygen has an atomic number of 8, meaning that it has 8 protons. Here we see 10 electrons, which means that we have 2 extra electrons as we should have 8. This will effect our charge. Using this, oxygen usually has a charge of -2 (can be found by looking at its location on the periodic table, the row in which it lies has a -2 charge). With two extra electrons, it has a charge of -4.
The mass number consists of your protons plus your neutrons. Our mass number here is 16. 16-8 protons means we have 8 neutrons. The number of protons in an element will not change, however the number of neutrons and electrons can, as seen in this example.
Answer: Plants take a lot of electricity to operate.
Reports show that almost 70<span>% of the world's desalination plants are located in the Middle East with Saudi Arabia producing 20%. </span>
Saudi Arabia runs the world’s largest thermal desalination plant, producing (640,000 m3 per day. Desalination plants like these take<span> a lot of electricity to operate thus Middle Eastern countries turn to it only as a last resort.</span>
Answer:D) accommodation
Explanation:
Accommodation is a term developed by psychologist Jean Piaget to define how we modify our existing knowledge as we learn new information.
Instead of eliminating the existing Information we adjust our schemas to accomodate what we have just learnt. Schemas refer to how we organise knowledge into patterns as we learn it.
For example a child learns what a bus is but may also refer to a train as a bus , when this child is told that this isn't a bus , she or he will modify the information he already had to understand what is a train , she or he will take note of the differences between the two in order to accomodate this new information.
