5.000 g of compound x with molecular formula c₄h₆ are burned in a constant-pressure calorimeter containing 25.00 kg of water at 25°c. the temperature of the water is observed to rise by 2.161 °c. (you may assume all the heat released by the reaction is absorbed by the water, and none by the calorimeter itself.) calculate the standard heat of formation of compound x at 25°c.
be sure your answer has a unit symbol, if necessary, and round it to 3 significant digits.
yep sure doodle wack back hey! hope this !
false, if you are saying that there is only one single atom of water.
the positively charged particles in the nucleus pull the negatively charged electrons. when we move from left to right, the number of protons increases then more protons attract negative charges, so electronegativity increases. this happens due to a greater charge on the nucleus which makes electron bonding pairs to be very attracted to atoms located more right on the periodic table. fluorine is the most electronegative element which is present in seventh group known as halogen group.
