The law of conservation of mass states that, for any closed system, the mass of the system must remain constant.
So, in other words, mass cannot be created nor destroyed.
In a burning log, the initial mass of the wood and the ashes that are left behind after it burns are different, which would seem to violate the law of conservation of mass.
Answer:
Lower.
Explanation:
Viscosity means thickness or consistency. Picture how sticky and dense chocolate syrup is compared to orange juice--syrup is more viscous.
Other examples - high viscosity = molasses, low viscosity = water.

Answer:
The retention factor, k is 2.49
Explanation:
According to the theory of High-Performance Liquid Chromatography (HPLC), the retention factor (or capacity), k, of a column is the ratio of the retention time of a retained analyte (toluene) to that of the un-retained solute (methane).
This implies that:
k =
= ![\frac{995 (secs)}{399 (secs)}](https://tex.z-dn.net/?f=%5Cfrac%7B995%20%28secs%29%7D%7B399%20%28secs%29%7D)
retention factor, k = 2.49.
Note that there is no unit for retention factor, as it is a ratio.
