Adding nitric acid to water is quite exothermic. Calculate the temperature change (AT) when 100.0 mL of water (d = 1.00 g/mL) at 19.4°C[cp = 75.3 J/(mol · °C)] and 10.0 mL of concentrated HNO3(15.0 M,AHsoln = -33.3 kJ/mol) are combined.

7.7 g of citric acid (MM = 192.1 g/mol) can be titrated with NaOH according to the following balanced chemical equation.           H3C6H5O7  (aq) + NaOH(aq) → H2O(l) + Na H2C6H5O7(aq) what would the curve for the titration of the neutralization of the three hydrogens of this acid with NaOH look like?

Predict whether the following will fully dissociate, partially dissociate, or not dissociate when dissolved solution. Provide a balanced equation for the hyderation of each compound. 1) NaI (s) Sodium iodide. 2) Pyruvic ACID HO 3) glucose H₁2 (s)

Each row of the table below describes an aqueous solution at 25 °C. The second column of the table shows the initial components of the solution. • Use the checkboxes in the third column to explain the type of the initial solution. The fourth column describes a change in the solution. • Use the fifth column to predict how the change in the solution will change its pH. initial type solution initial components (check all that apply) change effect of change on pH (check one) acidic pH higher H₂O A basic add KNO3 pH lower neutral pH the same acidic pH higher B H₂O, NaOH basic add HClO4 pH lower neutral pH the same acidic pH higher C H₂O basic add KOH pH lower neutral pH the same acidic pH higher H₂O, NaOH basic add NaC104 pH lower neutral pH the same
