Both carbon 12 and carbon 14 have the same no. of Electrons but the difference is carbon 14 has more neutrons
graphite is a form of carbon in which carbon atoms are arranged in a layer.
Answer : The mass of potassium phosphate needed will be 3.98 grams.
Explanation : Given,
Molarity of potassium phosphate = 0.75 M = 0.75 mole/L
Molar mass of potassium phosphate = 212.27 g/mole
Volume of solution = 25.0 mL = 0.025 L (conversion used : 1 L = 1000 mL)
Molarity : It is defined as the number of moles of solute present in one liter of solution.
In this problem solute is, potassium phosphate.
Formula used :
![\text{Molarity}=\frac{\text{Mass of solute}}{\text{Molar mass of solute}\times \text{volume of solution in liter}}](https://tex.z-dn.net/?f=%5Ctext%7BMolarity%7D%3D%5Cfrac%7B%5Ctext%7BMass%20of%20solute%7D%7D%7B%5Ctext%7BMolar%20mass%20of%20solute%7D%5Ctimes%20%5Ctext%7Bvolume%20of%20solution%20in%20liter%7D%7D)
Now put all the given values in this formula, we get:
![0.75mol/L=\frac{\text{Mass of solute}}{212.27g/mole\times 0.025L}](https://tex.z-dn.net/?f=0.75mol%2FL%3D%5Cfrac%7B%5Ctext%7BMass%20of%20solute%7D%7D%7B212.27g%2Fmole%5Ctimes%200.025L%7D)
![\text{Mass of solute}=3.98g](https://tex.z-dn.net/?f=%5Ctext%7BMass%20of%20solute%7D%3D3.98g)
Therefore, the mass of potassium phosphate needed will be 3.98 grams.

Advances in Technologies with Relevance to Biology: The Future Landscape
This chapter provides an overview and a perspective on the breadth and types of technologies that may have an impact on the life sciences enterprise of the future, with the understanding that there are inherent difficulties in anticipating or predicting how any of these technologies alone or in combination will alter the nature of the future threat “landscape.”
Rather than attempt to cover the technology landscape in a comprehensive manner, this chapter (1) highlights technologies likely to have obvious or high-impact near-term consequences; (2) illustrates the general principles by which technological growth alters the nature of future biological threats; and, (3) highlights how and why some technologies are complementary or synergistic in bolstering defense against future threats while also enhancing or altering the nature of future threats.

Answer:
I believe it would be 2
Explanation:
if there are 2 nitrogen molecules then there would have to be 2 hydrogen molecules but this could be completely wrong
if this happens to be right, ur welcome :3 here's a Jay Jay pic for u cuz why not
