Answer:
![[NH_2NO_2]=0.0868M](https://tex.z-dn.net/?f=%5BNH_2NO_2%5D%3D0.0868M)
Explanation:
Hello,
In this case, for the given chemical reaction, the first-order rate law is:
![r=\frac{d[NH_2NO_2]}{dt} =-k[NH_2NO_2]](https://tex.z-dn.net/?f=r%3D%5Cfrac%7Bd%5BNH_2NO_2%5D%7D%7Bdt%7D%20%3D-k%5BNH_2NO_2%5D)
Which integrated is:
![[NH_2NO_2]=[NH_2NO_2]_0exp(-kt)](https://tex.z-dn.net/?f=%5BNH_2NO_2%5D%3D%5BNH_2NO_2%5D_0exp%28-kt%29)
Thus, the concentration after 31642.0 s for a 0.384-M solution is:
![[NH_2NO_2]=0.384M*exp(-4.70x10^{-5}s^{-1}*31642.0s)\\](https://tex.z-dn.net/?f=%5BNH_2NO_2%5D%3D0.384M%2Aexp%28-4.70x10%5E%7B-5%7Ds%5E%7B-1%7D%2A31642.0s%29%5C%5C)
Best regards.
Answer:
Magma becomes rock after the heating process has settled.
Explanation:
Magma is a kind of lava or in other words "Hot melted rock". When rock get really hot it transforms from rock it's solidified state and becomes magma. When magma is hot it can stay that way for a while or until it cools down. When magma does cool down it starts the solidifying state start to come out. If you let the magma cool it will become rock again. This process will happen over and over and it never stops. Every time magma gets cool it hardens, every time it gets hot it melts or and becomes magma. So in conclusion magma only turns back when it has been heated up and liquify.
Answer:
Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is.
