Answer:
All of the above
Explanation:
All of this is in the solar system.
Answer:- ![4.15*10^-^2^0\mu L](https://tex.z-dn.net/?f=4.15%2A10%5E-%5E2%5E0%5Cmu%20L)
Solution:- It is a volume unit conversion problem where we are asked to convert the volume from
to microliters.
We know that:
= 1 mL
![1mL=10^-^3L](https://tex.z-dn.net/?f=1mL%3D10%5E-%5E3L)
and, ![1L=10^6\mu L](https://tex.z-dn.net/?f=1L%3D10%5E6%5Cmu%20L)
Let's use these conversions factors for the desired conversion using dimensional as:
![4.15*10^-^2^3cm^3(\frac{1mL}{1cm^3})(\frac{10^-^3L}{1mL})(\frac{10^6\mu L}{1L})](https://tex.z-dn.net/?f=4.15%2A10%5E-%5E2%5E3cm%5E3%28%5Cfrac%7B1mL%7D%7B1cm%5E3%7D%29%28%5Cfrac%7B10%5E-%5E3L%7D%7B1mL%7D%29%28%5Cfrac%7B10%5E6%5Cmu%20L%7D%7B1L%7D%29)
= ![4.15*10^-^2^0\mu L](https://tex.z-dn.net/?f=4.15%2A10%5E-%5E2%5E0%5Cmu%20L)
So, the answer is
.
The noble gases are helium, neon, argon, krypton, xenon, radon, and ununoctium. The noble gases are relatively nonreactive. This is because they have a completevalence shell<span>. They have little tendency to </span>gain<span> or lose </span>electrons. <span>These gases all have similar properties under standard conditions: they are all odorless, colorless, monatomic gases with very low chemical </span>reactivity<span>. The six noble gases that occur naturally are helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).</span>
Formula of isocyanic acid is HNCO. It colourless, volatile compound. It is poisonous inorganic compound. Melamine is synthesized from urea. The reaction involves two steps. In first step, urea gets converted to isocyanic acid which is an intermediate. In the second step, isocyanic acid gives melamine (molecular formula C₃H₆N₆) and carbon dioxide (CO₂). The balanced chemical reaction involved in second step is given below:
6 HNCO → 1 C₃N₃(NH₂)₃ + 3CO₂
The co-efficient of the reaction are: 6, 1, 3
