Answer:
Pretty sure its B sorry if im wrong
Explanation:
Answer:


Explanation:
In this case, we have to start with the <u>reagents</u>:

The compounds given by the problem are:
-) <u>Nitrogen gas</u> = 
-) <u>Water vapor</u> = 
-) <u>Aluminum oxide</u> = 
Now, we can put the products in the <u>reaction</u>:

When we <u>balance</u> the reaction we will obtain:

Now, for the enthalpy change, we have to find the <u>standard enthalpy values</u>:





With this in mind, if we <u>multiply</u> the number of moles (in the balanced reaction) by the standard enthalpy value, we can calculate the energy of the <u>reagents</u>:

And the <u>products</u>:

Finally, for the total enthalpy we have to <u>subtract</u> products by reagents :

I hope it helps!

Answer:
Electrons get farther from the nucleus.
Explanation:
By going from the top to the bottom of a group, the atomic number increases. That would mean that:
- The number of orbitals increases, as there are more electrons.
- A higher atomic number implies an increasing number of neutrons.
- As there are more electrons, they get farther from the nucleus. The farther an electron is from the nucleus, the easier it is for the electron to be removed from the atom.
