Question

Which energy diagram best illustrates a reaction that is thermodynamically favored but kinetically slow? The more massive a radioactive decay particle is, the higher its ionizing power and lower its penetrating power. Which radioactive decay particle has the highest ionizing power and lowest penetrating power? Alpha particle beta particle gamma ray positron What is the missing nuclide in the synthesis of ununocium, Uuo? _101^249 Md _98^243 Cf _98^247 CY _98^249 Cf One version of the Clausis-Clapeyron equation is ln P_vap = -Delta H_vap/RT + ln beta. The slope of a straight-line plot of can be used to determine the enthalpy of vaporization. P_vap vs. 1/T ln P_vap vs. 1/T, P_vap vs. T In P_vap vs. T The cubic unit cell for an oxide of rhenium is shown here. What is the empirical formula of this rhenium oxide? ReO_2 ReO_3 Re_2 O_3 Re_g O_12 The heating curve for aluminum is shown here. The melting point for aluminum is 658 degree C, which relationship is used to determine the amount of heat added in the section of the heating curve indicated by the arrow? q = m times Delta H q = m times Delta H q = m times c times (758 - 458 degree C) q = m times c times (758 - 658 degree c) What is the primary attraction when gaseous Br_2 condenses? Covalent bond formation London dispersion forces dipole-dipole attraction hydrogen bonding As the molar masses of molecular substance increase generally their bonding points and vapor pressure decrease, decrease increase, increase decrease, increase increase, decrease

Explanation / Answer

Dear,

42) Thermodynamically favourable reation products have lower energy compared to reactants. So options A & C are eliminated.

Kinetically slow reactions have higher activation energy. So correct answer is option B.

43) Alpha particle have highest ionizing power and lowest penetrating power.

44) option D.

Atomic mass and Atomic number remains same before and after the reation.

here, atomic mass - 297 and atomic number 118.
