Answer:
with the molecular formula C3H5(ONO2)3, has a high nitrogen content (18.5 percent) and contains sufficient oxygen atoms to oxidize the carbon and hydrogen atoms while nitrogen is being liberated, so that it is one of the most powerful explosives known.
Explanation:
NTG reduces preload via venous dilation, and achieves modest afterload reduction via arterial dilation. These effects result in decreased myocardial oxygen demand. In addition, NTG induces coronary vasodilation, thereby increasing oxygen delivery.
Neutrons actually don't carry an electrical charge, which is why they are called neutrons because they are "Neutral".
B. It has a negative charge and much less mass than a proton.
Given :
Volume , V = 500 mL .
Molarity , M = 0.5 M .
Molecular mass of NaCl is
.
To Find :
How many grams of NaCl is required .
Solution :
Let , NaCl required is x gram .
Molarity is given by :
![M=\dfrac{\text{Number of moles}}{\text{Volume (in liters) }}\\\\M=\dfrac{m}{M\times V}\\\\0.5=\dfrac{x}{58.4\times 0.5}\\\\x=0.5^2\times 58.4\ g\\\\x=14.6\ g](https://tex.z-dn.net/?f=M%3D%5Cdfrac%7B%5Ctext%7BNumber%20of%20moles%7D%7D%7B%5Ctext%7BVolume%20%28in%20liters%29%20%7D%7D%5C%5C%5C%5CM%3D%5Cdfrac%7Bm%7D%7BM%5Ctimes%20V%7D%5C%5C%5C%5C0.5%3D%5Cdfrac%7Bx%7D%7B58.4%5Ctimes%200.5%7D%5C%5C%5C%5Cx%3D0.5%5E2%5Ctimes%2058.4%5C%20g%5C%5C%5C%5Cx%3D14.6%5C%20g)
Hence , this is the required solution.
Answer:
These three numbers, n, ℓ, and s can be used to describe an electron in a stable atom.
Explanation:
Each electron's quantum numbers are unique and cannot be shared by another electron in that atom. This property is called the Pauli Exclusion Principle.
Hope this helps!!! :)))
