The answer is (4). If you look at a Maxwell-Boltzmann energy curve, you will see that lowering the activation energy will increase the proportion of molecules with sufficient energy for a successful reaction collision. Therefore, a reaction with lower activation energy will proceed more quickly. Often, this lower activation energy is obtained by another mechanistic pathway. Catalysts increase reaction speed through these two basic mechanisms.
Answer: 2.04 moles
Explanation:
Mass of H2SO4 = 200g
RMM of H2SO4 = (2*1) + 32 + (16*4)
= 2 +32 +64 = 98
n = Mass concentration / RMM
n = 200/98
n = 2.04moles
Its D, malleable. I need to have 20 characters, so there you go.
The percent composition of a compound is calculated with the molecular formula: divide the mass of each element found in one mole of the compound by the total molar mass of the compound
A conductor is a object that allows an electrical current to pass through it. An insulator does not let electrical currents pass through it but protect other objects from the electrical current. Conductors work to move currents to other spaces and Insulators work to minimize the transfer of heat energy.
