How do astronomers observe and learn about celestial objects?

Chemistry
1 answer:
MatroZZZ [7]3 years ago
8 0

Answer:

Astronomers use a number of telescopes sensitive to different parts of the electromagnetic spectrum to study objects in space. Even though all light is fundamentally the same thing, the way that astronomers observe light depends on the portion of the spectrum they wish to study.

If gravity is the ONLY force acting on an object, then the force of
Earth's gravity produces acceleration of 9.8 meters per second²
downward.  That number doesn't change, and it doesn't depend
on the mass or weight of the object.

If there are any other forces acting on the object at the same time,
like air resistance or some other kind of friction for example, then
all bets are off, and we can't say what the object's acceleration will
be in that case.

What is the empirical formula of a compound containing carbon, hydrogen, and oxygen in the ratio 14:42:84?
Alexxandr [17]
<h3>Answer:</h3>

D. CH₃O₆

<h3>Explanation:</h3>
  • We are given the ratio of carbon, hydrogen and oxygen in a compound as 14: 42 : 84

We are supposed to determine the empirical formula of the compound;

  • We need to know what is an empirical formula;
  • An empirical formula of a compound is a formula that shows the simplest whole number ratio of elements in a compound.

In this case;

The ratio of C : H : O is 14 : 42 : 84

  • Note, this is not the simplest ratio.

But we can simplify further to get the simplest whole number ratio;

  • Therefore, 14 : 42 : 84  is equal to 1 : 3 : 6
  • Thus, the simplest whole number ratio of C : H : O in the compound is 1 : 3 : 6
  • Therefore, the empirical formula of the compound is CH₃O₆
