An ionic<span> crystal consists of </span>ions<span> bound together by electrostatic attraction. The arrangement of </span>ions<span> in a regular, geometric structure is called a crystal lattice. Examples of such </span>crystals<span> are the alkali halides, which include: potassium fluoride </span>
Answer:
its 1 not negative
the atom shown below was hydrogen, known as H.
Explanation:
The volumetric flow rate of water will be as follows.
q = 
= 0.0378 
Diameter = 
= 0.2032 m
Relation between area and diameter is as follows.
A = 
= 
= 0.785 x 0.2032 x 0.2032
= 0.0324 
Also, q = A × V
or, V = 
= 
= 1.166 m/s
As, viscosity of water = 1 cP = 
Pa-s
Density of water = 1000 
Therefore, we will calculate Reynolds number as follows.
Reynolds number = 
= 
= 236931.2
Hence, the flow will be turbulent in nature.
Thus, we can conclude that the Reynolds number is 236931.2 and flow is turbulent.

Answer:
Explanation:
Upon arrival we needed to hunt in this new land we only had five refills and they needed 50 g of gunpowder to be shot once. We only have 15 pounds of gunpowder. It is taking six shots to kill one of these wild turkeys. How many turkeys can be shot with 15 pounds of gunpowder?
If we had plenty of refills, and it takes 6 shots to kill a wild turkey at 50 gms of gunpowder per shot, then each turkey requires 6X50 =300gms of gunpowder. We have 15X454 gms of gunpowder and have the potential to kill 15X454/300=22.7 or 22 turkeys.and it takes 6 shots to kill a wild turkey.
The limiting reagent is the number of refills, and withonly 5, we are out of luck and can't kill one turkey
