Find the average of these 2 temperatures, since they have the same volume.

(80 + 10) ÷ 2 = 90 ÷ 2 = 45°C

You can only use this method of averaging them out because they have the same volumes :)

Answer:

Explanation:

In the picture you have the answer.

Now, let's analize the structure, so you can know why the structure in the picture is the correct structure.

The aniline is the name that receives the benzene with a NH2 group as one of it's substituent. Now, This group is a really strong activating group and in the nomenclature priority, it has more order priority than any halide.

Now, it says that the chloro it's on the para position. The "para" position in a aromatic ring, in this case, the benzene, refers to the position of this substituent to the first substitued position. In this case, the NH2 it's on the position 1 or carbon 1, the para position, means that it's on position 4 of the ring. The ortho position is carbon 2, and meta position is carbon 3 of the benzene. So, according to this, the p-chloroaniline it's on picture attached.

What is the problem with mental models?
Nataly [62]

Mental models also guide your perception and behavior. They are the thinking tools that you use to understand life, make decisions, and solve problems. Learning a new mental model gives you a new way to see the world—like Richard Feynman learning a new math technique. Mental models are imperfect, but useful.

hope this helped :)

On the basis of significant figures, the accuracy of measurement made using an analytical balance is more reliable.

<h3>What is an analytical balance?</h3>

An analytical balance is a special type of weighing balance that has a reputation for obtaining the mass of very small objects even as low as milligrams. It consists of a transparent glass casing and a scale.

On the basis of significant figures, the use of an analytical balance to determine the weight will improve the accuracy of the determination since it determines the mass to more significant figures.
