Decide whether a chemical reaction happens in either of the following situations. If a reaction does happen, write the chemical equation for it. Be sure your chemical equation is balanced and has physical state symbols. situation A strip of solid magnesium metal is put into a beaker of 0.027M PdCl₂ solution. Explanation chemical reaction?

Lithium batteries are used throughout our modern world – in cell phones, laptops, tablets, etc. In fact, if you are regularly recharging your device, it’s highly likely it contains a lithium ion battery. The lithium iron phosphate battery provides stable function over time. The overall reaction for the lithium iron phosphate battery is below: LiFePO4 + 6 C -> LiC6 + FePO4 A certain lithium battery weighs 0.6 g and has a capacity of 2250. mA hr (that is, the cell can store charge equivalent to a current of 2250. mA flowing for 1 hr). What is the capacity of this cell in coulombs? What mass of the reactants is needed to deliver 2250. mA hr? What percentage of the cell mass consists of reactants?

Choose all reactions that are redox reactions. 1.) C6H12O6(s) + 6 O2(g) > 6 CO2(g) + 6 H20(1) 2.) Al(s) + 3 HCI(aq) -› AlClg(aq) + 3/2 H2(g) 3.) 2 HNO3(aq) + Ca(OH)2(aq) > Ca(NO3)2(aq) + 2 H20(L) 4.) Fe3+ (ag) + SCN (aq) -> FeSCN2 (aq)

While you are working in a hospital laboratory, a patient complaining of severe stomach cramps and labored respiration dies within minutes of being admitted. Relatives of the patient tell you that he may have ingested rat poison. Therefore, you have his stomach pumped to verify this and to determine the cause of death. One of the more logical things to do would be to attempt to isolate the agent that caused death and perform chemical analyses on it. Assume that this was done, and the analyses showed that the isolated chemical compound contained, by weight, 60.0% potassium, 18.5% carbon, and 21.5% nitrogen. What is the chemical formula for this compound?
