Which too factors determine whether a collision between two reactant molecules will result in a reaction? select all that apply.
The energies of the colliding particles much be equal to each other.
The particles must be in the correct orientation upon impact.
The particles must collide with enough energy to meet the activation energy of the reaction.
The particles must be charged.
Determine the mole fraction of each component to at least three significant figures.
Concentrated hydrochloric acid is 12 M and has a density of 1.18 g/mL. Calculate the mass in grams of a 0.025 L sample of concentrated hydrochloric acid.
What fraction of the total residues are branch points? B) How many reducing ends does this amylopectin have?
How many milliliters of 0.125 M HCl are needed to completely neutralize 48.0mL of 0.102 M Ba(OH)2 solution? How many milliliters of 0.122 M H2SO4 are needed to neutralize 0.210g of NaOH?
A calorimetry experiment determined that the combustion of 1.01 g of H2 reacting with excess O2 producing H2O gave q=143 kJ. Calculate the change in enthaply.
Consider the combustion of methanol: 2 CH3OH(g) + 3 O2(g) 2 CO2(g) + 4 H2O(g). If CO2 is produced at the rate of 0.8 mol/s, what is the rate of consumption of O2?
A 3.77g sample of oxalic acid (H2C2O4x2H2O) was dissolved in enough water to make 1000 mL of solution. Then 17.15mL of this oxalic acid solution was titrated to the end point with 22.05mL of an unknown sodium hydroxide soloution.
Torsional strain is exhibited during exclipsed Newman Projections. Where would steric hindrance be demonstrated? At any point in a Newman Projection
Calculate w (in kJ) when 137 g iron (III) oxide (MM = 159.7 g/mol) reacts with excess carbon to produce carbon dioxide gas at 345 K:
Compound A is optically active and has the molecular formula C5H10O. On catalytic hydrogenation (addition of hydrogen) of A, Compound B is obtained
Concrete used in road construction is reinforced using steel bars in a grid, known collectively as "rebar." After many years, rebar will begin to corrode, and the concrete will weaken.
Calculate the empirical formula of the compound (CxHyOz). B) If the 4.00g sample corresponds to 0.0666 moles of a compound, what is the molecular formula of the unknown molecule (CxHyOz)
