Answer:
B. When it is obtained by rounding, as in 3.0
Explanation:
Because they are in group 1 of the periodic table (alkali metals), they all have the same properties. They each are malleable, good conductors of electricity, highly reactive, and have low melting points.
2KF(s) -----> 2K(s)+F2(g)
False
Explanation:
Dispersion forces are the weakest of all intermolecular forces. They are appropriately called London dispersion forces or LDF.
- They are the weakest form of intermolecular forces.
- Crystal lattice forces are the strongest intermolecular forces that holds crystalline substances together.
- London dispersion forces are weak attractions found between non-polar to polar molecules and noble gases.
- The attraction is as a result of non-polar substances becoming polar in nature.
- This is due to the constant motion of electrons which leads to uneven distribution of electrons.

Hello there!
Aspartame has 4 kilocalories of energy per gram and table sugar has 3.9 kilocalories. They are pretty much same but aspartame is 200 times sweeter than sucrose so probably would be aspartame that has more calories.
