Problem- Using average bond enthalpies, predict which of the following reactions will be most exothermic: (i) C(g)+2F2(g)?CF4(g) (ii) CO(g)+3F2?CF4(g)+OF2(g) (iii) CO2(g)+4F2?CF4(g)+2OF2(g)) Explain the trend, if any, that exists between reaction exothermicity and the extent to which the carbon atom is bonded to oxygen.
I require expert help to solve the above question. Illustrate each and every step.
The observation that a solid is colorless permits you to suggest that a broad category of elements is probably not present in this solid. Explain what is the general name for this category of elements
A particular coal contains 2.92% sulfur by mass. When this coal is burned, the sulfur is converted into sulfur dioxide gas. The sulfur dioxide gas then reacts with calcium oxide to form solid calcium sulfite
(The specific heats of ice, steam, and liquid are 2.03 J/g · °C, 1.99 J/g · °C, and 4.18 J/g·°C, respectively. The heat of fusion is 6.02 kJ/mol and heat of vaporization is 40.79 kJ/mol.)
A .100g sample of a carbon, hydrogen, oxygen compound was burned in a stream oxygen and produced 0.220 g CO2 and .239 g H2O. what is the mass percent of hydrogen in the sample
Provide the name of the major alkene product that results when (2S,3S)-2-bromo-3-methylpentane is treated with sodium methoxide in methanol.
the combustion of octane c8h10 with molecular ocygen is an exothermic reaction that produces carbon diocide and water.
when atoms of the hypothetical element x are placed together they rapidly undergo reaction to form the x2nbspmoleculea.
Carbon tetrachloride CCl4 was once used in the cleaning industry before people realized it was a carcinoginic compound. Millions of tons of carbon tetrachloride was made in the 50's by reacting carbon disulfide
A solid laboratory sample contains two substances, lead(II) carbonate and potassium carbonate. A 5.000 g sample of this unknown was treated with aqueous nitric acid to dissolve it, then, after further treatment to adjust the acidity
in covalent molecules some valence electrons are shared and others are not. what are these types of electrons called?
The normal boiling point for acetone is 56.5°C. At an elevation of 5300 ft the atmospheric pressure is 630. torr.
Compound A --> Compound B if you start with 10.0 mL of Compound A and obtain 9.0 g of Compound B. Density of Compound A = 0.75 g/mL MW of Compound A = 150. g/mol MW Compound B = 300.
