a- CO2 and CO2
b- CO2 and CH4
c- NH3 and NH3
d- NH3 and CH4
e- CH4 and CH4
how do you figure out the answer to this question?
1. You know what makes a dipole.
2. You review to see which has two dipoles.
Symmetry is a big clue in this. CO2 are linear molecules, CH4 is a symmetrical (tetrahedral) molecule, and NH3 is not symmetrical, with a double unshared pair of electrons on one side.
What type(s) of intermolecular force is (are) common to each of the following. (Select all that apply.) 1) Xe and methanol (CH3OH) a)london-dispersion forces b)dipole-dipole c)hydrogen bonding i put a and b but it was wrong 2)CH3OH and acetonitrile (CH3CN)
Which type of intermolecular forces would be expected in a sample of F2 gas? a. London forces, dipole interactions, and ionic interactions b. dipole interactions c. London forces d. London forces and dipole interactions I believe C is the correct answer.
Put in order from strongest to weakest: London Dispersion Forces, Hydrogen Bonds, Dipole-dipole interactions, ionic bonding, and covalent bonding.
Calculate the value of Kp for the equation C(s)+CO2(g)2CO(g) Kp=? given that at a certain temperature C(s)+2H2O(g)CO2(g)+2H2(g) Kp1=3.33 H2(g)+CO2(g)H2O(g)+CO(g) Kp2=.733 Please show detailed steps.
Balance the following equations. 3. C12H22O11 + O2 = CO2 + H2O Answer: C12H22O11 + 12 O2 = 12 CO2 + 11 H2O 8. CH3OH + O2 = CO2 + H2O Answer: 2 CH3OH + 3 O2 = 2 CO2 + 4 H2O I balanced all the others just fine. But I seem to be having trouble with these two.
How many molecules are in 2.10 mol CO2? A. 2.53 x 10^24 molecules B. 3.79 x 10^24 molecules C. 3.49 x 10^24 molecules D. 1.26 x 10^24 molecules*** I think it is D, but can someone check my work? Amount of mols x Avogadro's number (2.10 x 6.02 x 10^23) 1.26
in which chemical reaction is the number of atoms in the reactants the same as the number of atoms in the products? a. Zn+2HCI->H2+ZnCI2 b. CH4+O2->CO2+2H2O c. CO2+CH2OH+O2 d. Li2CO3->LiO+CO2
Silver will spontaneously reduce which of the following? Reaction E (volts) Na+ + e- ---> Na -2.71 Co2+ + 2e- ---> Co -0.28 Ag+ + e- ---> Ag .80 A) Na B) Co2+ C) Na+ D)Co E) None of these
What is the percent yield of CO2 if a reaction using 10.0 g CO with excess O2 produces 12.8 g CO2? 2CO + O2 → 2CO2
The mechanism for the reaction described by NO2(g) + CO(g) ---> CO2(g) + NO (g) is suggested to be (1) 2NO2(g) --->(k1) NO3(g) + NO (g) (2) NO3(g) +CO(g) --->(k2) NO2(g) + CO2(g) Assuming that [NO3] is governed by steady-state conditions, derive the rate
