Because the electrons in a molecule of hydrogen fluoride (HF) are more strongly pulled toward the fluorine atom the molecule is nonpolar.?
That statement is incorrect. HF is a polar molecule because fluorine is more electronegative than hydrogen, causing the electron density to be pulled closer to the fluorine atom. As a result, HF has a partial positive charge on the hydrogen atom and a partial negative charge on the fluorine atom.
What equation show exothermic reaction?
Hf, reactants > Hf, products
Oxidation is a reaction in which a compound or molecule gains electrons thereby giving it negative character?
this statement is false!! ------------------------------------------------ Platoweb.com :)
A molecule that has a negative and poositve end is?
A molecule that has a negative and positive end is a polar molecule.
Is the reaction between HF and NaOH an endothermic or exothermic reaction?
EXTREMELY!!!!! exothermic. As in fires and explosions exothermic.
What does a negative Hf for molecule mean?
Energy was released when the molecule was formed from its elements
How is Hf related to the H of a reaction?
The Hreaction is the difference between Hf, products and Hf, reactants
Is HF a oxyacid?
HF is not an oxyacid; no oxygen in the molecule.
How does the H reaction relate to the Hf of molecules involved in a reaction?
Hreaction = Hf products - Hf reactants

How does the Hreaction relate to the Hf of molecules involved in a reaction?
Hreaction = Hf, products - Hf, reactants
What is the formula equation hydrogen gas reacts with fluorine gas to produce hydrogen fluoride gas?
H2 + F2 -> 2HFhydrogen + fluorine -> hydrogen fluorideOne molecule of hydrogen reacts with one molecule of fluorine to produce two molecules of HF.
Which of the following describes an exothermic reaction A. ht reactants equals 0 B. ht reactants ht products C. ht equals ht D. ht ht?
Hf, reactants > Hf, products apex
which of the following describes an endothermic reaction?
Hf, products > hf, reactants
What equation show exothermic reaction?
Hf, reactants > Hf, products
How is the H related to the H of a reaction?
The h reaction is the difference between Hf products and Hf reactants - apex
How is delta hf related to the delta h of the reaction?
^Hreaction = ^Hf, products - ^Hf, reactants Apex
