Answer:
How many grams of copper (II) nitrate is formed
Answer:
Carbohydrates are energy-providing feed components composed of carbon, hydrogen, and oxygen. They should make up about 75 percent of an animal's diet. The energy they provide powers muscular movements. Carbohydrates also produce the body heat that helps keep the animal warm.
A particle is a minute fragment or quantity of matter. In the physical sciences, a particle is a small localized object to which can be ascribed several physical or chemical properties such as volume or mass. ... The term is rather general in meaning, and is refined as needed by various scientific fields.
Answer:-
and
radiation.
Explanations:- Alpha particle is helium nucleus with two protons and two neutrons and so it has +2 charge where as gamma is a form of light, so these are rays and not particles. Since these are rays, the charges for gamma rays is zero means they are neutral.
When alpha particles are passed through electromagnetic field they are repelled by the positive plate and attracted by the negative plate as there is an attraction between opposite charges. So, the line we see towards positive plat is representing an alpha particle radiation.
Since gamma rays are neutral, they are not deflected in electromagnetic field and go straight. So, the other line in the diagram is representing gamma rays radiation.
Answer:
The initial concentration of ethanal was 0.1590 mol/L.
Explanation:
Integrated rate law for second order kinetic:
![k=\frac{1}{t}(\frac{1}{[A]}-\frac{1}{[A]_o})](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B1%7D%7Bt%7D%28%5Cfrac%7B1%7D%7B%5BA%5D%7D-%5Cfrac%7B1%7D%7B%5BA%5D_o%7D%29)
k = Rate constant =
t = Time elapsed = 50.0 s
=initial concentration of ethanal
[A] = Concentration of ethanal left after time t = 0.151 mol/L
On substituting the value:
![6.73\times 10^{-3} L mol s=\frac{1}{50.0 s}(\frac{1}{0.151 mol/L}-\frac{1}{[A_o]})](https://tex.z-dn.net/?f=6.73%5Ctimes%2010%5E%7B-3%7D%20L%20mol%20s%3D%5Cfrac%7B1%7D%7B50.0%20s%7D%28%5Cfrac%7B1%7D%7B0.151%20mol%2FL%7D-%5Cfrac%7B1%7D%7B%5BA_o%5D%7D%29)
![[A]_o=0.1590 mol/L](https://tex.z-dn.net/?f=%5BA%5D_o%3D0.1590%20mol%2FL)
The initial concentration of ethanal was 0.1590 mol/L.
