The answer is powder because if it was a small crystal it the molecules are tightly compact same with the small cube but there less compact, powder is loose and more spread out and easier to mix so it would react the fastest
The answer is higher.
You should know that the London dispersion force is the weakest intermolercular attractive force while the hydrogen bonds form a high attractive intermolecular force, so you have to expect that in molecules forming hydrogen bonds the molecules will be more attached to each other than in similar-sized molecules that interact by London dispersion forces only, which takes you to conclude that the melting point of the molecules forming hydrogen bonds will be higher.
The two types of data are Qualitative and Quantitative data. Qualitative data is the data that cannot be quantified or measured where as quantitative data is quantified that is measured in terms of numbers.
The given statement 17 birds drink from the pond over the course of 2 hours describes the number of birds that drink water over a given amount time. So, it represents quantitative data. Hence the given statement that The following statement describes qualitative data: 17 birds drink from the pond over the course of 2 hours is false.
The calculation equation for density is density = mass / volume. So the density for this material is 52.457/13.5=3.886 g/cm3.
