The aluminum cup inside your calorimeter weighs 39.78 g. you add 50.01 g of ice cold water to the calorimeter. you measure the temperature of the calorimeter to be 0.5oc just before your next addition. you then add 50.72 g of hot water and a 49.98 g metal object, all having an initial temperature of 69.5oc. after the calorimeter reaches thermal equilibrium, the final temperature is measured to be 35.9oc. what is the specific heat of the metal object, in units of j g-1 oc-1. assume that: the calorimeter is completely insulated the heat capacity of the empty calorimeter is the heat capacity of the aluminum cup: 0.903 j g-1 oc-1. the density of water is: 1.00 g/ml. the heat capacity of water is: 4.184 j g-1 oc-1.

If the mass of the products measured 120g what would the mass of the reactants a. 30g b. 60g c. 120g d. 240g

What royal scientist used the 29th day of frozen vapor to encounter elements for mastering new culinary creations?

Many reactions take place in aqueous solution. when potential reactants are mixed, a reaction will occur if there is some driving force that favors the formation of products. it is often convenient to categorize reactions in terms of these driving forces: precipitate formation, in which an insoluble solid is formed, weak electrolyte formation, as in a neutralization reaction involving water, or transfer of electrons, as in a redox reaction. these reactions can be represented by full molecular equations, which contain all species in the reaction mixture, or by net ionic equations, which show only the species that actually undergo a change. the latter does not contain the spectator ions, which do not undergo a net change or do not take part in the reaction. part a when the following two solutions are mixed: k2co3(aq)+fe(no3)3(aq) the mixture contains the ions listed below. sort these species into spectator ions and ions that react. drag the appropriate items to their respective bins. view available hint(s) spectator ions ions that react part b what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.ba(oh)2(aq)+h2so4(aq)→ express your answer as a chemical equation. view available hint(s) nothing provide feedback
