Answer: well the answer is a
Explanation: how because I did that
Answer:
See explanation
Explanation:
Electron affinity is the energy released when an extra electron is added to a neutral gaseous atom. A negative value of electron affinity indicates that energy is given out and vice versa.
Metals have positive electron affinity since electrons rarely accept electrons, so;
Na(g)+ 1e^- → Na^-(g) positive
Mg(g)+1e^- → Mg^-(g) positive
For the last case; Br(g)+ 1e^- → Br^-(g), the electron affinity for the non-metals is negative. hence the answer
It reflects light from the Sun; The moon has phases because it orbits the Earth so you can already rule out every other answer. The moon also has no way of absorbing/producing illumination on its own.

Answer:
New ideas would be created and tested
Explanation:
<em>All old ideas would be discarded.
</em>
<em>
Scientific evidence would be weakened.
</em>
<em>
New ideas would be created and tested.
</em>
<em>
The limitations of science would be evident.</em>

In science, old ideas are usually improved or modified and not entirely discarded. The old ideas form the basis for new ideas after extensive reviews. Differences in the interpretations made by scientists on any particular phenomenon give rooms for reviews. The reviews often generate new ideas or hypotheses and these can be tested using relevant experimental procedures according to the scientific method.
Hence, the correct answer would be that new ideas would be created and tested.
