1. Oxyacetylene torches are used for welding, reaching temperature near 2000 °C. These temperatures are due to the combustion of acetylene, C2H2, with oxygen.
a. Write a balanced equation for the combustion of acetylene.
b. Starting with 125 g of both C2H2 and O2, which reactant is limiting?
c. What is the theoretical yield of H2O from the reaction mixture?
d. If 22.5 g of water forms, what is the percent yield?
if phosphoric acid is pour into an aluminum can what would thereaction look like? we did this in lab to see if aluminum
What is the molarity of a solution made by mixing 25 mL of 8.0 M hydrocholoric acid with 300 mL of 2.0 M hydrocholoric acid
a fuel oil is composed of C10H22 and C12H26 when the fuel oil ios burned with 20% excess air the ratio of water to CO2 is found to be 1.088.
Estimate the mass of water that must evaporate from the skin to cool a body by 0.10, if the mass of the body is 91 and its heat capacity is 4.0 . (Assume that the heat transfer is 100 efficient.)
Calculate concentrations of OH- and the pH of each basic solution. Since NaOH donates on OH- ion for each NaOH molecule, the OH- concentration is equivalent to the NaOH molarity. The pOH is calculated as -log[OH-] and the pH is calculated as 14-pO..
Identify the reactant acting as an acid and the reactant acting as a base. Indicate whether the acid is Bronsted Lowry acid, Lewis acid or both.
which one of the following best describes the c3-c4 bond in 1-butene? a sp3-sp3 and sigma b sp2-sp2 and sigma c sp2-sp3
The molar enthalpy of fusion of ice at 0 Celcius is 6.02 kJ/mol; the molar heat capacity of supercooled water is 75.3 J/(mol-K). (a) One mole of supercooled water at -10 Celcius is induced to crystallize in a heat-insulated vessel.
a 0.1000m solution of ethanoic acid hc2h3o2 is only partially ionized so that h2.25x10-3m. what is the acid
Which element has 55 neutrons, 36 electrons, 40 protons and has a mass of 95. I know its 95Mo but does it have a ion charge of +2,+4,or+6? I've tried +2 and +6 but its wrong. Help would be appreciated.
If 5.85mL of 0.1000 M NaOH solution is needed to just neutralize excess acid after 20.00 mL of HCl was added to 1.00 g of an antacid, how many moles of acid can the antacid counteract per gram?
The CaCl2 is purchased in the hydrated form. it contains one mole of water for each mole of compound, NaCO3 * H2O, and had a formula weight of 124.01 g/mol.
