For the answer to the question above, Copper does not form a diatomic molecule. A diatomic molecule has only two atoms. Diatomic molecules are the molecule that is composed of two same atoms which are bonded covalently. An example is an oxygen, it exists as O2 and chlorine, it exists as Cl2. I hope my answer helped you.

A diatomic molecule is one that forms a bond between two of the same molecule. The main diatomic molecules are Hydrogen, Oxygen, Nitrogen, Fluorine, Chlorine, Bromine, and Iodine. There are many reasons in quantum mechanics for this answer, but the simplest way to think about this is that the atoms want to have an outer shell of eight electrons, except for hydrogen, which wants to have two. Hydrogen, nitrogen, and chlorine can all bond with another atom of the same type to satisfy their full outer shell. Copper, on the other hand, does not form with one other copper to form Cu2, so the answer is D. Copper.

2. What is the difference between an organ and an organ system
aleksandrvk [35]
The difference between an organ and a tissue is that basically tissues are a group of similar cells that works together. Then a group of tissue that works together would make up an organ. Groups of organ working together later makes up an organ system. This is the main difference between an organ and a tissue.

How was or wasn't the scientific method followed in this experment
Andreas93 [3]

Answer:

The best answer would be:

C. The scientific method was followed because the experiment tested the hypothesis and produced reliable results.

Explanation:

The purpose of an experiment is to test the hypothesis. It is true that having an experimental group and a control group was following the scientific method but the data gathering and documentation was also part of the scientific method. So the best answer would be C.

Writing the question is not necessary. It is merely part of forming a hypothesis. The scientific method does not require many scientists to perform the experiment, but it does require that the experiment be repeatable, so it can be tested again.

Which climate is most likely found in a high pressure belt
Mice21 [21]

Answer:subtropical highs. ... Near the poles the pressure is high and it is known as the polar high. These pressure belts are not permanent in nature

Explanation: The horse latitudes are subtropical regions known for calm winds and little precipitation. ... Unable to sail and resupply due to lack of wind, crews often ran out of drinking water. To conserve scarce water, sailors on these ships would sometimes throw the horses they were transporting overboard.

How many moles of gas occupy 98 l at a pressure of 2.8 atmosphere and a temperature of 292
lara [203]

Answer:

n = 11.45 mol

Explanation:

Given data:

Number of moles = ?

Volume of gas = 98 L

Pressure = 2.8 atm

temperature = 292 K

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

2.8 atm × 98 L = n × 0.0821 atm.L/ mol.K   × 292 K

274.4 atm.L = n ×  23.97atm.L/ mol

n = 274.4 atm.L /23.97atm.L/ mol

n = 11.45 mol

Calculate the energy difference for a transition in the paschen series for a transition from the higher energy shell n=4. expres
Troyanec [42]
Electrons are orbiting around the nucleus in a specific energy level as described in Bohr's atomic model. There are 7 energy levels all in all; 1 being the strongest and nearest to the nucleus, and 7 being the weakest and farthest away from the nucleus. Electron can transfer from one energy level to another. If it increases energy, it absorbs energy. If it goes down an energy level, it emits energy in the form of light. This light can be measure in wavelength through the Rydberg equation:

1/λ =R(1/n₁² -1/n₂²), where
λ is the wavelength
R is the Rydberg constant equal to 1.097 × 10⁻7<span> per meter
n</span>₁ and n₂ are the energy levels such that n₂>n₁

In the Paschen series is an emission spectrum of hydrogen when the energy level is at least n=4. So, this covers n=4 to n=7.

1/λ =(1.097 × 10⁻7)(1/4² -1/7²)
λ  = 216.57 ×10⁻⁶ m or 216.57 μm
