While rummaging through the cabinets in your winery lab, you find a container of liquid labeled only, HCl (aq). Wondering if it will be sufficiently strong to remove the rust from your 37 Buick, you are able to reach equilibrium (at pH 7.00) through titration by adding 14.25 mL of 0.2030 M NaOH to 20 mL of this solution. What is the Molarity of the acid?
50 g of aluminum oxide is produced in the reaction of aluminum metal and oxygen gas at STP. How many liters of oxygen gas were reacted?
Application of ideal gas law - How high can you raise the temperature of the gas without bursting the vessel?
Find out the concentration of this solution in a)M (molarity), b) m (molality), c) % w/w (percent by mass). If solvent =, H 2 O.
The temperature of a 35.2 g sample of iron increases from 23.7 C to 29.5 C. If the specific heat of iron is 0.450 J/g-K, how many joules of heat are absorbed.
Anton Von L. a 17th century pioneer in the use of the microscope, described the microrganisms he saw as "animalcules" whose length was "25 thousandths of an inch."
octane has a density of 0.692g/ml at 20C. How many grams of O2 are required to burn 30.5 gal of C8H18
If 200 g of water at 20 degrees celcius absorbs 41840 J of energy, what will its final temperature be
What mass of iron is needed in order to supply the energy needed to warm 15.0mL of water (d= 1.00 g/cm3) from 23C to 37C
What is the pH of the resulting hydrochloric acid solution and 0.40 g of hydrogen chloride (HCl)is dissolved in water to make 6.0L of solution
A solution is prepared by condensing 4.00L of a gas, measured at 27°C and 746mmHg pressure into 58.0g of benzene. Calculate the freezing point of this solution.
Normally the alkaline earth carbonates (MCO3; M = Mg^2+, Ca^+2, Sr^+2, Ba+2) are insoluble in water. Why would the method used in this experiment work for calculating the molar mass of the alkaline earth? How would the calculations have to be cha..
Identify the two important classes of catalysts. Analyze the chemical reactions that take place when a biological catalyst combines with a reactant (substrate) to form an unstable intermediate.
