Answer:
81.0
Explanation:
mutiply the value by 101.325 to get the answer a. 81.1
Answer:
a. The central atom is sulfur
b. SF2
c. The central atom has two lone pairs
d. The ideal angle between the sulfur-fluorine bonds is 109.5°
e. I expect the actual angle between the sulfur-fluorine bonds to be less than 109.5° because unbonded pairs repel bonded pairs more than bonded pairs repel other bonded pairs. So the bonds here will be pushed closer than normal
The answer is (C) The electrons are moving easily between the nuclei of metal atoms.
The explanation:
-The electrons then move freely throughout the space between the atomic nuclei. ... Metals are good conductors of electricity because the electrons in the electron sea are free to flow and carry electric current. Metals are ductile and malleable because local bonds can be easily broken and reformed.
1-Metals are good conductors of electricity because the electrons in the electron sea are free to flow and carry electric current.
2-Metals are ductile and malleable because local bonds can be easily broken and reformed.
3-Metals are shiny. Light cannot penetrate their surface; the photons simply reflect off the metal surface. However, there is an upper limit to the frequency of light at which the photons are reflected.
I'm assuming that by "miles" you mean moles.
If O2 is the excess reactant, that means Fe is the limiting reactant. That means that the amount of product being formed depends on the amount of Fe reactant present. To calculate the moles of Fe2O3 formed, start with the given 6.4 moles of Fe and use the mole to mole ratio given by the reaction as shown below:
6.4 mol Fe x
=
3.2 mol Fe2O3
Answer:
the Ray's go right through it
Explanation:
the Ray's are so small they punch right through them
