<span>N2H4 is a polar molecule </span>
The balanced chemical reaction is:
<span>C + H2O → CO + H2
</span>
We are given the amount of carbon to be used in this reaction. This will be the starting point of the reaction.
<span>34 g C ( 1 mol C / 12.01 g C ) ( 1 mol H2/ 1 mol C) (2.02 g H2 / 1 mol H2) = 5.72 g H2
Apparently, the correct answer is not in the given choices.</span>
Answer:
The halogens located in group 17
Explanation:
The change in energy of a neutral atom when an electron is added is known as electron affinity. <em>Fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At) are known as halogens and conform the group 17 of the periodic table, the group that presents higher electron affinity.</em> This characteristic happens because of their atomic structures, it is easier for them to gain electrons because they are closer to form octets.
Here I present you halogens' electron affinities values:
- Fluorine (F) -328 kJ mol-1
- Chlorine (Cl) -349 kJ mol-1
- Bromine (Br) -324 kJ mol-1
- Iodine (I) -295 kJ mol-1
<em>The use of negative signs is to indicate the RELEASE of energy.</em>
I hope you find this information useful and interesting! Good luck!
Hydrofluoric acid is not a strong acid despite being a hydrohaulic acid (hydrogen and a halogen). HF is highly corrosive and can be used to dissolve most oxides
