Why is the robotic surgical system a bit like a video game?
koban [17]
It is a bit like a video game because when you dumb it down, it's basically a small robotic thing that is controlled by a controller. In video games, you have an avatar being controlled inside a game using a gamepad, in surgery you have a little machine inside of a person's body being controlled using a computer.

The reaction 2a → a2​​​​​ was experimentally determined to be second order with a rate constant, k, equal to 0.0265 m–1min–1. if
olga nikolaevna [1]
According to the second order formula:
1/[At] = K t + 1/[Ao]
and when we have the K constant =0.0265 & we have t = 180 min & we have the initial concentration of A = 4.25 so by substitution:

1/[At]  = 0.0265 X 180min + 1/4.25 
1/[At] = 5
∴[At] = 1/5 = 0.2 m

How many unique 13C NMR signals exist in the spectrum for the following compound?
yawa3891 [41]

Answer:

                   Five signals exist in the spectrum of 4-methylpent-1-ene.

Explanation:

                   Nuclear Magnetic Resonance (NMR) is the main technique used by Scientists particularly by Chemists to elucidate the structure of compounds mainly organic compounds.

                   There are different NMR techniques which are used to characterize different NMR active nuclei like ¹H-NMR, ¹³C-NMR, ¹⁵N-NMR, ¹⁹F-NMR e.t.c.

                   In given case the compound will show five different signal for six carbon atoms. THis is because among the six carbon atoms two of them have same electronic environment means they are having same electron surrounding thus, they will share a signal at same ppm. Hence, the signals and each signal shown by each carbon atom is shown below.
