If we graph data and notice a trend that is approximately linear, we can model the data with a line of best fit. A line of best fit can be estimated by drawing a line so that the number of points above and below the line is about equal.

NettetBack to Results. The Turning Point of the Aerosol Era Over the CMIP6 historical period (1850–2014), aerosols provided the largest negative forcing compared to all other climate forcings via their ability to absorb or scatter solar radiation and alter clouds. Aerosols played an important role in counterbalancing warming by greenhouse gases (GHGs). In chemistry, the linear molecular geometry describes the geometry around a central atom bonded to two other atoms (or ligands) placed at a bond angle of 180°. Linear organic molecules, such as acetylene (HC≡CH), are often described by invoking sp orbital hybridization for their carbon centers. According to the VSEPR model (Valence Shell Electron Pair Repulsion model)…

Nettet3 concentration of N 2, H 2, or NH 3.Say we monitor N 2, and obtain a rate of - d[N 2] dt = x mol dm-3 s-1. Since for every mole of N 2 that reacts, we lose three moles of H 2, if we had monitored H 2 instead of N 2 we would have obtained a rate - d[H 2] dt = 3x mol dm-3 s-1.Similarly, monitoring the concentration of NH 3 would yield a rate of 2x mol dm-3 s …
