In fireworks, the heat of the reaction of an oxidizing agent, such as kclo4, with an organic compound excites certain salts, which emit specific colors. strontium salts have an intense emission at 641 nm. what is the energy (in kj) of this emission for 5.33 g of the chloride salt of strontium? assume that all the heat produced is converted to emitted light. enter to 2 decimal places.

The alkali metals (group 1) consist of lithium (3), sodium (11), potassium (19), rubidium (37), cesium (55), and francium (87). they are soft, metallic solids with low densities and low melting points. based on the data shown in figure 1, how many valence electrons do alkali metals share?

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.

What type of organic molecule comprises the majority of a potato?
