Bonding and Compound Questions1.) Do all ionic compounds dissolve in water, Do all covalent compounds dissolve in water? answer should be 50 to 100 words.
2.) Do the physical properties of water change when a compound is dissolved in water? If so, which properties change and why?
3.) Do all chemical compounds undergo each type of chemical reaction,i.e. synthesis, decomposition, metathesis-precipitation, metathesis-neutralization, redox-single displacement, redox-combustion and can this information be useful to a criminal investigation?
A compound is heated to produce gas whose molecular mass is to be determined. The gas is collected by displacing water in a water filled flask inverted in a trough of water
Glycerol HOCH2CH(OH)CH2OH is a nonvolatile, water-soluble material. its density is 1.25 g/mL. Predict the vapor pressure of a solution of 2.40 x 10^2 mL of glycerol, in 395 mL of water, at the normal boiling point of water.
3.5 g of a hydrocarbon fuel is burned in a vessel that contains 250. grams of water initially at 25.00 C. After the combustion, the temperature of the water is 26.55 C.
A cook wants to heat 1.35 of water from 32.0 to 100.0 .If he uses the combustion of natural gas (which is exothermic) to heat the water, how much natural gas will he need to burn.
Determine what would be the concentration of the final solution If you take a ten mili litres portion of the stock solution and dilute it to a total volume of 0.250 Litres,?
Calculate the mass percent of methanol, ethanol, and MTBE, that must be present in gasoline to yield a mixture of 1.8% oxygen by weight.
A lime-soda softening plant treats a flow of 150 MGD, and the water has 86 mg/l CO2. The commercial grade of quicklime has a purity of 85% and the soda ash has a purity of 95%.
Nitrogen dioxide (NO2) cannot be obtained in a pure form in the gas phase because it exists as a mixture of NO2 and N2O4. At 25°C and 0.98 atm, the density of this gas mixture is 2.7 g/L.
Determine what would be its temperature after absorption of 9.4 * 10-2 kWh of heat If 1.45 L of water is initially at 25.0 °C,?
Determine how many moles of carbon dioxide should be added to the system to bring the equilibrium carbon monoxide concentration to 0.743 mol/L
Calculate the enthalpy of the reaction: 2NO(g) + O2(g) --> 2NO2(g) given the following reactions and enthalpies of formation: 1/2 N2(g) + O2(g) --> NO2(g), delta H *A = 33.2 kJ 1/2 N2(g) + 1/2O2(g) --> NO(g), delta H *B= 90.2 kJ
The magnesium and calcium ions present in seawater([Mg2+] = 0.059 M and [Ca2+] = 0.011 M) can be separated by selective precipitation with KOH.
