Answer: Yes
Explanation:
due to the nitrogen atom and its lone pair is in opposition to the moment associated with the three polar N-F bonds in NF3. NCl3 also has a small dipole moment
Koby needed to break the baking soda to provide a larger surface area for reaction thereby increasing the rate of reaction.
<h3>Rate of reaction?</h3>
The term rate of reaction refers to how quickly or slowly a reaction proceeds. The surface area of solid reactants is an important factor that influences the rate of reactions when a solid reactant is involved.
Hence, Koby needed to break the baking soda to provide a larger surface area for reaction thereby increasing the rate of reaction.

Strong acids. hope this helps :)
Answer:
Wt Avg Atomic Wt = 28.0577 amu
Explanation:
Atomic Mass = ∑Wt Avg contributions of isotopes of an element
Si-28 => 92.21% => 0.9221 decimal fraction => Wt Avg Si-28 = 0.9221(27.9769) = 25.7695 amu
Si-29 => 4.69% => 0.0469 decimal fraction => Wt Avg Si-29 = 0.0469(28.9765) = 1.3590 amu
Si-30 => 3.10% => 0.0310 decimal fraction => Wt Avg Si-30 = 0.0310(29.9737) = 0.9292
Wt Avg Atomic Wt = ∑Wt Avg Contributions = (25.7695 + 1.3590 + 0.9292)amu = 28.0577 amu
