<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>
<h2>Hope it helps </h2>
I believe the correct answer is no, it is impossible to have 5.0*10^-25g of Al. One atom of Al weighs <span>4.48*10^-23 g/atom Al which means</span> it is impossible to have any weight of Al less than that. Hope this answers the question. Have a nice day.
Answer:
B, C, E
Explanation:
What you are trying to do is increase the solute/solvent ratio.
B. Adding more solute increases the value of the numerator, so it increases the ratio.
C. Boiling away some solvent decreases the value of the denominator, so it increases the ratio.
E. Heating the solution so more solute dissolves increases the value of the numerator, so it increases the ratio.
A is wrong. Adding more solvent makes a more dilute solution.
D is wrong. The solvent dissolves the solute.
