Ber [7]

Answer:

Alchemy is a practice of making gold from other metals.

Explanation:

Alchemy is a method which is practiced by the ancient scientists of Europe, Africa and Asia trying to produced gold from other metals. This method was failed to produced gold from metals and all scientist suggested that metals can not be converted into gold. Greeks were the people who presented the theory of alchemy in the first few centuries of CE.

5. Extend your thinking: What strategies did you use to hunt for moths?

Sonja [21]

Answer: There are many strategies used to hunt and kill moths. I’ll tell you my way of hunting and killing moths.

Step-By-Step Explanation:
Morning and Afternoon: First, get a sticky trap. You can get it at Target or Walmart. Cover it with moth pheromones or anything you know that can attract the moths. The sticky trap, will stick them to the trap and will eventually die after no being able to escape for a long time.
Nighttime: Buy or Get a lamp and turn it on. This will attract lots of moths and it will help you see them. Then, spray insecticide or insect repellent at the. Lastly, they should die.
Tip: If things get too out of hand with a huge swarm of moths, then call pest control and they will surely get rid of them for you!

How would I find the answer?

ELEN [110]

Answer:

Kr

Explanation:

The noble gas that is isoelectronic with Br⁻ is krypton.

This is because krypton is the closest noble gas to Br on the periodic table.

Electronic configuration of Bromine is;

2, 8, 18, 7

Br⁻ becomes; 2, 8, 18, 8

Krypton is; 2, 8, 18, 8

According to the kinetic molecular theory, which statement describes the particles of an ideal gas? -1)The gas particles are arr

avanturin [10]

Answer: option # 4, the collisions of the gas particles may result in the transfer of energy.

Explanation:

The kinetic molecular theory (KMT) explains the behavior and properties of gases in terms of the energy, the size, and the motion of the gas particles.

In terms of size, according to the KMT the gases are formed by small particles separated from each other in a vacuum. The volume of the particles is negligible and it is considered that they do not occupy any space.

Since the particles are separated they do not exert either attraction or repulsion to each other.

Regarding the motion, the particles are in constant random motion. They move in straight lines until collide with other particles or with the walls of the veseel. The collisions are elastic (the total kinetic energy is conserved). The kinetic energy may be trasferred between the particles, but the total kinetic energy does not change.

The kinetic energy and the temperature are related: the temperature is a measure of the average kinetic energy of the particles of gas. At a given temperature all the gases have the same average kinetic energy.

Now, check every choice:

1)The gas particles are arranged in a regular pattern:

False. The particles occupy all the volumen and are in random motion.

2) The force of attraction between the gas particles are strong:

False. The particles are separated and they do not exert any force on each other.

3) The gas particles are hard spheres in continuous circular motion.

False. The particles travel in straight until they collide.

4) The collisions of the gas particles may result in the transfer of energy.

True. When particles collide they may transfer kinetic energy but the total kinetic energy is conserved.
