5. Use the known reactions to determine the AHxn of the following reaction.
C2H4(g) + Cl2 (8) - C2H4C12 (1)
4 HCl (g) + O2(g) → 2 Cl2(g) + 2 H2O (1)
AH° = -202.4 kJ/mol
2 HCI (g) + C2H4 + 1/2O2(0) CH. Cl20) + H2O (1) AH° = -318.7 kJ/mol

Word equation for k(s)+h2o(l) yield koh(aq) + h2(g)

If 15 drops of ethanol from a medical dropper weight 0.60g, how many drops does it takes from a dropper to dispense 1.0ml of ethanol? the density of ethanol is 0.80g/ml

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
