Answer:

The source of the activation energy needed to push reactions forward is typically heat energy from the surroundings.

Explanation:

The activation energy of a particular reaction determines the rate at which it will proceed. The higher the activation energy, the slower the chemical reaction will be

When 6.0 mol Al react with 13 mol HCl, what is the limiting reactant, and how many moles of H2 can be formed? 2Al + 6HCl → 2AlCl
4vir4ik [10]

Well, we need to find the ratio of Al to the other reactant.


Al:HCl = 1:3


--> this means that for every 1 Al used, you have to use 3 HCl.



6*3 = 18 moles of HCl needed to fully react with 6 moles of Al. Since 13<18, HCL is the limiting reactant.



The ratio of HCl:AlCl = 3:1



13/3 = 4.3333...



The final answer is HCl is the limiting reactant with 4.3 moles of AlCl3 able to be produced.



Hope this helps!!! :)

Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. it is often called the
Tema [17]

Water is often referred as a <span>universal solvent </span>because it is capable dissolving much more solutes as compared to any other solvent.  This is because, water is a high polar molecule. In water, H has partial positive charge while O has partial negative charge. 


Due to this, water favors dissociation of molecules into positively and negatively charged ions. Positively charge ions gets attracted  towards oxygen i.e. negatively charges, while negatively charged ions get attracted towards positive end of water molecule. 


However, it is worth nothing that, despite water being referred as universal solvent, many compounds are insoluble or partially soluble in water. For instance, most of the hydroxide displays poor solubility in water.
