Answer:
Heat, light and electricity can all be used to move electrons between orbitals. The electrons are what allow atoms to react with each other in chemical reactions, and they are also what cause certain compounds to emit light when heated. When an atom is heated up, it starts to vibrate intensely. I hope this helped you. :)
Answer:
5.physical change
6.chemical change
7.physical change
8.conservation of mass
9.thermal energy
10.physical change
I honeslty dont know if this is right
explanation:
<span>Answer: option 3) magnesioum reacts with an acid.
</span><span />
<span>Justification:
</span><span />
<span>1) Malleability, conduction of electricity, and boiling point are physical properties.
</span><span />
<span>2) Maleability is the ability to be transformed into foil. It is just a change in form. So, it is a physical property.
</span><span />
<span>3) The metals conduct electricity in virtue of the array of the atoms, which permtis the flow of the electrons, but it does not involve a chemical change, so it remains being a physical proerty.
</span><span />
<span>4) Boling point is the temperature at which a substance passes from liquid state to gas state, which are just different forms of the same substance. So, it is other physical property.
</span><span />
<span>5) Reaction with an acid is indeed a chemical transformation: the metal (magnessium) will form a chemical bond with some spieces of the acid to form a new compound. This is a chemical reaction in virtue of the chemcial properties of the substance (its ability to react with acids)</span>
<h2>Hey there!</h2>
<h3>The reaction given is called Decomposition reaction. </h3>
<h2>Explanation:</h2>
<h3>Here we can see that Magnesium Carbonate (MgCO3) is heated and as a result it has given two compounds which are Magnesium Oxide(MgO) and Carbon Dioxide (CO2).</h3>
<h3>Decomposition reaction:</h3>
- A reaction in which a chemical compound breaks into simpler parts in when heat is applied to it.
<h3>So,we concluded that the reaction given above is a Decomposition reaction. </h3>
