A student takes 0.05 moles of HCl and reacts it with 0.05 moles of sodium hydroxide in 100 g of water solution in a styrofoam cup calorimeter. The empty calorimeter has a heat capacity of 0J/degrees C, and the temperature changed from 21.0 degrees C to 27.5 degrees C.
HCl (aq) + NaOh (aq) ------> H2O (l) + NaCl (aq)
Only include the heat capacity of water, and neglect heat capacity and specific heat of the HCl and NaOH.
a.) Calculate the heat of the reaction for the sample (kJ)
b.) Calculate the heat of the above reaction in J/mol of HCl.
Assume that you have an aqueous solution of an unknown salt. Treatment of the solution with dilute NaOH, Na2SO4, and KCl produces no precipitation. Which of the following cations might the solution contains?
3.20 Existing records reveal the following information about events A and B, where A = a long March warm spell and B = an April flood. Are variables A and B independent. Prove.
The rate constant for reaction A is doubled when the temperature is increased by 10 degrees. The rate constant for reaction B is tripled by 10 degree increase in temperature
A turbine operates by the impact of a high velocity jet of steam against the turbine blades. The steam leaves the turbine at a lower velovity.
What is the freezing point of the solution. Melting point (CCl4): -22.92 C Melting point (C6H6): 5.5 C K(CCl4): 2.65 C/m K(C6h6): 3.92 C/m
Chemicals found in water include a minerals such as a.calcium, silica and magnesium b. lead c.arsenic d.all of the above
write the name and the structural formula of the organic product that would result from the reaction below. dont forget
If specific amount of carbon reacts with 1.00 g, 1.50 g, and 2.00 g of Hydrogen to form compounds of A, B, and C respectively,
A sample of Oxygen is collected in a 206 mL container over water at 15C, and the barometer reads 793 torr. What volume would the dry gas occupy at 704 torr and 15C? Water's partial pressure at 15C is 12.8 torr. Answer in units of mL.
how many milliliters of 0.42 M solution of acetic acid, CH3COOH, will contain 0.50 grams of acetic acid
A 0.115 M solution of a weak acid (HA) has a PH of 3.33. Calculate the acid ionization constant (Ka) for the acid.
