88226Ra→ 86222Rn + 24He is the reaction that describes an alpha emission because radiations are released.
<h3>Describes an alpha emission?</h3>
Alpha radiation occurs when the nucleus of an atom becomes unstable and alpha particles are released in order to restore stability. Alpha decay occurs in elements that have high atomic numbers, such as uranium, radium, and thorium etc.
So we can conclude that 88226Ra→ 86222Rn + 24He is the reaction that describes an alpha emission because radiations are released.

Answer:- The speed of the satellite is 7.6
.
Solution:- It's a unit conversion problem that could be solved using dimensional analysis which is also known as train trail method.
The given speed of the satellite is 17000 miles per hour and we are asked to convert it to kilometers per second.
given:
1 Kilometer = 0.62 mile
1 hour = 3600 second
Let's use this given info and plug in the values to make the set up as:
= 7.616
We round the answer to two significant figures, since the given number(17000) has only two significant figures.
Hence, the speed of the satellite is 7.6 .
Well usually a tornado forms when hot air and cold air come together and in the south, but since the weather is cold and they live by mountains a tornado would not happen.
A hurricane happens by the ocean.
I believe the answer would be a rainstorm. <span />
Answer:
this reaction is so the answer should be A
Answer:
Since the chemical composition of the substance stays the same, such as that of water in the above mentioned example, melting and boiling are physical changes. And hence, boiling points and melting points are physical properties. Since they are a property of the material, they can be used to identify it.
Explanation:
