The formation constant* of [M(CN) 2 2 ]− is 5.30 × 10 18 5.30×1018 , where M is a generic metal. A 0.150 0.150 mole quantity of M(NO3) is added to a liter of 0.650 0.650 M NaCN solution. What is the concentration of M+ ions at equilibrium?

Aglow stick contains a glass vial with chemicals. when the glow stick is bent, the vial breaks and the chemicals react to produce a glow. a science student observes that a glow stick kept in the freezer glows for a longer duration than a glow stick kept at room temperature. what conclusion can be drawn based on the observation? be sure to note the outcome and test variables in the conclusion.

Why does a plastic bottle that is sealed at a high altitude change it’s shape when taken to lower altitude

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
