The mixture used in today’s experiment was prepared as a 1: 1: 1 mixture (by mass) of sand, salt, and salicylic acid. what does this underlined term mean? do your results for the mass of each recovered solid indicate a 1: 1: 1 composition of the mixture? (firstly to mathematically calculate your own ratio, divide the smallest mass into itself and then into each of the two larger masses)

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.

The identities of substances are the same before and after which type of change

If a gas has an initial pressure of 101kpa and a volume of 10l, then it expands to a volume of 20l, what is the new pressure?
