A neutralization process is a reaction between an acid and a base which yields a salt and water. From the choices, a neutralization reaction would be: 2 HBr + Ca(OH)2 yields CaBr2 + 2 H2O. Moreover, <span>NH3 + HCl yields NH4Cl is also a neutralization reaction. The complete reaction is actually NH4OH + HCl --> NH4Cl + H2O. NH4OH is the aqueous solution of NH3. This reaction is still a neutralization reaction.
On the other hand, the reaction </span><span>HCl + HBr yields H2 + ClBr is not valid. There is no reaction between HCl and HBr because both are strong acids. They would just dissociate into ions like H+, Cl- and Br-.
The valid reaction that is clearly not a neutralization process is </span><span>H2 + Br2 yields 2 HBr. This is a combination reaction yielding a strong acid HBr.</span>
Answer:
B. Extreme heat and pressure.....
Explanation:
This is how sedimentary rocks are actually made. I had learned recently in my class about these rocks, and my teacher told that these are made by heat and pressure. And these are the types of rocks that you'll find in canyons for example Grand Canyon.
You know that when something gets pressurized then it changes shape, same for rocks, if they're having lots of pressure on them, then they will also basically turn into newer rocks and also change shape. They also change looks because sedimentary rocks don't look like any other type of rock.
Also, heat can also be found in the crust of the earth since there is the Mantle under the crust which is filled up of MAGMA! (supa hot magma!! woohoo!) And also, because all of the dirt and stuff underground is packed together, the friction can also create heat. As you know, heat makes things expand, you might have done this before.... when you learned about hot and cold gas, you might have also learned that hot gases are more larger, and require more volume than cold gas. That means that the size of the object changes, that too, it's not just for gas, it's for everything, <em>including rocks!</em>.
Hence, your answer is B. Extreme heat and pressure from inside the earths surface......

Have a great day!
Answer ( 3 ) :
<span>conversion of matter to energy .
</span>
hope this helps!
Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties.
Dalton based his theory on the law of conservation of mass and the law of constant composition.
The first part of his theory states that all matter is made of atoms, which are indivisible.
The second part of the theory says all atoms of a given element are identical in mass and properties.
The third part says compounds are combinations of two or more different types of atoms.
The fourth part of the theory states that a chemical reaction is a rearrangement of atoms.
Parts of the theory had to be modified based on the discovery of subatomic particles and isotopes.
So it could be used in every country(different languages) yet still understood
