We have the final answer as
<h3>20 kg</h3>
Hope this helps you
I believe the correct answer from the choices listed above is option C. The ratio of Al3+ ions to S2- ions in a neutral compound would be 2:3. When it is a neutral compound the chemical formula would be Al2S3. As you can see in every 2 ions of Al you need 3 ions of S to maintain neutrality. Hope this answers the question.
A space probe is an unpiloted, unmanned device sent to explore space and gather scientific information. A space probe is launched from Earth with a set of scientific instruments and tools used to study the atmosphere and composition of space and other planets, moons, or celestial bodies. A probe may operate far out in space, or it may orbit or land on a planet or a moon. It may make a one-way journey, or it may bring samples and data back to Earth. Most probes transmit data from space by radio. There are different types of space probes because they collect different science information about very different environments. The probes must be able to withstand the various extreme environments to collect data. Humans have been sending space probes into space since the 1950s. The next generation of probes will study samples taken from comets, asteroids, and eventually Mars.
