Name and write formulas for alkenes, recognize physical properties of alkenes, and identify their isomers question what is true about the bonding in alkenes? select all that apply? select all that apply: the carbon-carbon double bond in an alkene contains one sigma (o) and one pi (1) bond. o the carbon-carbon double bond can freely rotate. o geometric isomers result from a different orientation of atoms in space. o alkanes and alkenes are named identically, including using the "-ane" suffix. feedback more instruction submit content attribution

For a family dinner, jose’s mom baked a loaf of bread. during the meal, his grandmother commented, “this bread is so dense! ” what do you think his grandmother meant by the word dense? you have some ideas regarding density already, but this experiment will enrich your understanding of the relationship between mass, volume and the density of objects. when making measurements in this experiment we will be using si units, the international system of units. the purpose of using si units is to have the ability to communicate and compare data results with other experiments without having to make conversions. measurement symbol si unit length m meter mass kg kilogram volume l liters density kg/l kilograms per liter any calculations that are performed during this experiment will ultimately be reported in scientific notation. recall that scientific notation is extremely important when we have data that is extremely small or large. scientists rely on a standard form of communication to quickly make hypotheses and judgements based on data. what is the density of block a? a0kg/l what is the density of block b? a1kg/l what is the density of block c? a2kg/l what is the density of block d? a3kg/l what is the density of block e? a4kg/l which block is the densest? a5
