Answer the following question given this paragraph: A large log placed in a fire will burn relatively slowly. If the same mass of wood were added to the fire in the form of small twigs, they would burn much more quickly. This is because the twigs provide a greater surface area than the log does. An increase in the surface area of a reactant increases the rate of a reaction. Surface area is larger when a given amount of a solid is present as smaller particles. A powdered reactant has a greater surface area than the same reactant as a solid chunk. In order to increase the surface area of a substance, it may be ground into smaller particles or dissolved into a liquid. In solution, the dissolved particles are separated from each other and will react more quickly with other reactants. Q: Why does a large log burn relatively slowly compared to the same mass of wood in the form of small twigs? Choices: - smaller blade area - larger surface area - larger surface area - smaller surface area A:
(Answer)
smaller surface area
Ques: Answer the following question given this paragraph: Carbon (atomic number 6) has six electrons. Four of them fill the 1s and 2s orbitals. The remaining two electrons occupy the 2p subshell. We now have a choice of filling one of the 2p orbitals and pairing the electrons or of leaving the electrons unpaired in two different, but degenerate, p orbitals. The orbitals are filled as described by Hund's rule: the lowest-energy configuration for an atom with electrons within a set of degenerate orbitals is that having the maximum number of unpaired electrons. Thus, the two electrons in the carbon 2p orbitals have identical n, l, and ms quantum numbers and differ in their ml quantum number (in accord with the Pauli exclusion principle). The electron configuration and orbital diagram for carbon are:. Q: Subshells are subdivisions of what groupings of electrons that can be found surrounding atoms? Choices: - globals - analogous - isotopes - orbitals A:
Ans: orbitals

Ques:Answer the following question given this paragraph: Q: When food is scarce, starving cells secrete a molecule that stimulates neighboring cells to do what? Choices: - compete - hoard energy - die off - aggregate A:

Ans:aggregate
Ques:Answer the following question given this paragraph: The instantaneous velocity of an object is the velocity of the object at a given moment. If the object is moving with constant velocity, then the instantaneous velocity at every moment, the average velocity, and the constant velocity are all the same. Q: What is defined as the velocity of the object at a given moment? Choices: - specific gravity - relativistic velocity - inertia - instantaneous velocity A:

Ans:
instantaneous velocity
