Answer 1

When Muhammad died, his followers carried on the new religion. Islam prospered and grew under the Caliph Abu-Bakr and those who followed him. What cities became hubs of Muslim thought and power? How did word of this new religion spread? Did it appeal to people outside the Arabian Peninsula?

Answer 2

The correct answer is C. The statement "The atom has 7 protons and 7 electrons" gives enough information to say that the atom is electrically neutral. This is because the number of positively charged protons in the atom is equal to the number of negatively charged electrons, resulting in a net charge of zero. Option A and B both have an unequal number of electrons and protons, so the atom has a net charge. Option D also has an equal number of neutrons and protons but does not give information about the number of electrons.
