Answer:
Error in measure= 1.55-1.32= 0.23
Orville's % error = 0.23/1.32*100% = 17.42%
Explanation:
Answer:
HCl=18.7g.
Explanation: First, we ensure that the equation is balanced. Then, we convert the given grams to moles of reactant.
the answer is A......
it is supported by practical evidence and examples. this is the answer because he tried and tested many different ways to see what would happen so he is happy with the conclusion that what he tested is what he gets.
Answer:
a. CH4 is only held together by London dispersion forces since any dipoles cancel out due to symmetry. On the other hand H2O has strong hydrogen bonds
b. PH3 has dipole-dipole forces while NH3 is held together by stronger hydrogen bonding
c. C2H6 and C3H8
. Both substances are held together by London dispersion forces since any dipoles cancel out due to symmetry. However C3H8 has the stronger London dispersion forces of the two because it is a larger molecule,
d. BH3 is held together by London dispersion forces since any dipoles cancel out due to symmetry while OF2 is held together by stronger dipole-dipole forces
