Mein Bruder liest Bücher in seinem Schlafzimmer.

Temperature: An increase in temperature increases diffusion rate. Concentration gradient (difference in concentration): A greater concentration gradient increases diffusion rate. Surface area of a membran...

bromine + sodium iodide --> sodium bromide + iodineBr₂ + 2NaI --> 2NaBr + I₂ Both bromine and iodine atoms have 7 electrons in their outer shells, a full shell contains 8 elect...

Notice that y has the same coefficient (ignoring the sign) in both equations. So, we will use the elimination method. The elimination method means that we will combine the two equations to eliminate the y...

First recognise that (x+5w/2)^0.5 is the same as the square root of (x+5w/2). Then square both sides of the equation to get: y^2=(x+5w/2).Multiply both sides by 2 to eliminate the fraction from the RHS: 2...
