Answer:
option c) 552 K is correct
Explanation:
we know that
0° C +273= 273 K
so
296° C+273=569 K
Answer:
b. Fe-O
Explanation:
A way to predict melting points for ionic compounds is with electronegativity.
Electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.
The most electronegativity difference (E.D.), the highest melting point, thus:
E.D. Al-N = 3,0 - 1,6 = <em>1,4</em>
E.D. Fe-O = 3,5 - 1,8 = <em>1,7</em>
E.D. W-C = 2,5 - 1,7 = <em>0,8</em>
The most electronegativity difference is from Fe-O, thus, this ionic compound will have the highest melting point.
I hope it helps!
Answer:
The overview of the subject is outlined underneath in the summary tab.
Explanation:
- The molar ratio seems to be essentially a balanced chemical equilibrium coefficient that implies or serves as a conversion factor for the product-related reactants.
- This ratio just says the reactant proportion which reacts, but not the exact quantity of the reacting product. Consequently, the molar ratio should only be used to provide theoretical instead of just a definite mass ratio.
