Compute the lattice energy (kJ/mol) of the hypothetical ionic compound MX2 from the information given below.IE1+ IE2 (M) = 1,780 kJ/molM(s) => M(g) ?Ho = 80.7 kJ/mol?Hof(MX2) = -956 kJ/molX2(g) => 2X(g) ?H = 197 kJEA (X) = -352 kJ/molIE1 (X) = 271 kJ/mol
The molar mass for NaCl and water are 58.443 g/mol and 18.015 g/mol, respectively. Calculate the partial molar volumes for NaCl and water in a 0.35m solution
A compound is found to have a molar mass of 598 g/mol. If 35.8 mg of the compound is dissolved in enough water to make 175 mL of solution at 25°C, what is the osmotic pressure of the resulting solution?
it was found that 19.31 ml of an hcl solution are needed to react completely with 322 ml of a lioh solution that has a
In the oxidation of glucose (C6H12O6), water and carbon dioxide are formed when the sugar is reacted with oxygen gas. If 4.39 grams of glucose are reacted, assuming 100% yield, how many moles of carbon dioxide would evolve?
The carbonyl peak of benzaldehyde appears as a very strong and intense peak at 1703 cm -1. Normally the carbonyl peak of an aldehyde appears at 1725 cm -1. Why does the carbonyl peak of benzaldehyde appear at a lower frequency
Why is water a reactant in the fermentationof sucrose? Enter the solubility-product expression
Why does bromine add faster to a disubstituted double bond than a monosubstituted double bond to produce dibromides
What volume will carbon dioxide originally 30.0 mL at 27°C have at 77°C
Suppose that a liquid is 11 times denser than water If you were to sip this liquid at sea level using a straw what would be the maximum length of the straw
