Thermochemistry equations project: modeling energy changes. in this assignment you will write and balance a chemical equation. then you will use a table of enthalpy values to calculate the energy charge in the reaction. next, you will create a model of the energy change in the reaction. finally, you will write an explanation that describes the energy change in the reaction

Balance this equation co2(g) + h2o (g) show that the balanced equation obeys the law if conversation of mass

Which of the following statements is true about planck’s law

Consider three unlabeled bottles, each contain small pieces of one of the following metals. - magnesium - sodium - silver the following reagents are used for identifying the metals. - pure water - a solution of 1.0 molar hcl - a solution of concentrated hno3 (a) which metal can be easily identified because it is much softer than the other two? describe a chemical test that distinguishes this metal from the other two, using only one of the reagents above. write a balanced chemical equation for the reaction that occurs. (b) one of the other two metals reacts readily with the hcl solution. identify the metal and write the balanced chemical equation for the reaction that occurs when this metal is added to the hcl solution. use the table of standard reduction potentials (attached) to account for the fact that this metal reacts with hcl while the other does not. (c) the one remaining metal reacts with the concentrated hno3 solution. write a balanced chemical equation for the reaction that occurs. (d) the solution obtained in (c) is diluted and a few drops of 1 m hcl is added. describe what would be observed. write a balanced chemical equation for the reaction that occurs.
