I because it is an acid, it should be soluble in hexane
Average kinetic energy of a particle :
0.5 mv^2 = kT/2
so the kinetic energy = kT/2
assuming the same value of K
T1 = -49 + 273 = 224
T2 = 287 + 273 = 560
E2 / E1 = kT2 / 2 / kT1 / 2
E2 / E1 = T2 / T1
E2 / E1 = 560 / 224 = 2.5
so the average kinetic energy of the particle increases by 2.5
True !! size dependent properties state is only one of the many physical properties of matter some physical properties such as massive value depending on the size or the amount measures of these properties very depending on how much matter is in a sample.
A chemical reaction of exothermic kind releases energy in the form of heat and light.
We are given that reactant releases 27.4kJ/g for every gram of reactant consumed.
We are required to find number of grams of reactant that has been consumed
It is also given that 880J of energy is released
Hence, grams of reactants consumed is 880/27.4gm

For machines such as a rake the output force is less than the input force. If the input force of the rake is 10 newtons and the output force is 5 Newtons mechanical advantage is .5
