fourth period
The third period is similar to the second, except the 3s and 3p sublevels are being filled. Because the 3d sublevel does not fill until after the 4s sublevel, the fourth period contains 18 elements, due to the 10 additional electrons that can be accommodated by the 3d orbitals.
Hi there in this question we have a cube that has a volume Of 187 ml. And we would like to know this volume and inches cute. Alright so first thing I want to do is to convert two cm cubed and I can do that quite easily because a militia leader and a centimeter cubed are the same. Okay so millimeter will cancel. So actually we have 187 cm cubed. Now we need to convert two inches. There are 2.54 centimeters in one inch. But we need this cube. So I am going to cube this step because that will give us centimeters cubes. So that centimeters cubed will cancel and it will give us an answer. They are in inches cubed. Alright so I did go ahead and just Cube this 2.54. You can do it as you're doing part of the calculation or do it separately. And I got 16.39 centimeters cubed. Okay so now it's just a matter of taking 187 And dividing it by 16.39 the centimeters cube will cancel And we'll have an answer in inches cubed. We want that answer in three significant digits because 187 had three. So that ends up being 11 0.4 inches cute. All right and that is our final answer. This Cube has a volume of 11.4" cute. Thank you so much for asking your question and I hope this was helpful
Answer: Flammability is a material's ability to burn in the presence of oxygen.
Explanation: Chemical properties can be observed only when the substance changes into one or more different substances through chemical reactions or transformations. One of the chemical properties is flammability.
Flammability is a material's ability to burn in the presence of oxygen.
Remember, oxygen doesn't burn. Precisely flammable substances obtain substances that burn. Oxygen remains an oxidizing agent, which means it supports the combustion process. Oxygen causes other objects to catch fire at low temperatures and burns hotter and faster. But oxygen itself does not burn. Consequently, if you at present deliver fuel and fire, adding oxygen will provide the fire.
Carbon dioxide is the result of combustion. An example can be seen in firewood in a fireplace. One of the chemical properties of carbon-based wood is having the ability to burn. Chemically the wood turns into carbon dioxide when it burns and leaves a residue of ash. Furthermore, this ash residue cannot be turned back into the wood. Chemical changes result in new substances.
Consider an example of a combustion reaction to methane gas:
Our balanced equation for methane combustion implies that every one CH₄ molecule reacts with two O₂ molecules. The product of combustion is one carbon dioxide molecule and two steam or water vapor molecules.
