1. what is the functional groups and molecular formula of aspartame
O O O| | | | ||HOCCH2CHCNHCHCOCH3| |NH2 CH2|aromatic circle
the O|| is above the 1st, 4th and 6th C
the NH2 is below the 3rd C and the CH2 is below the 5th C
A volume of 95.0 ml of H2O is initially at room temperature (22.0 C). A chilled steel rod at 2.00 C is placed in the water. If the final temperature of the system is 21.1 C .
Chemical analysis of the two compounds reveals that 0.25 mol ACl 2 has a mass of 100.0 g and 0.50 mol BCl 2 has a mass of 125.0 g. Determine what are the molar masses of ACl 2 and BCl 2 ?
Calculating the rate of disappearance of HCl, The rate of disappearance of HCl was measured for the following reaction
I dissolved .5 grams of mustard in 3 mL of distilled water. I was asked to determine the mass percentage of acetic acid in mustard, so I added 2.5 mL of NaOH to turn the mustard solution red.
A white solid remains in centrifuge tube after acetone extraction-it fizzes when hydrochloric acid is added suggesting sodium carbonate was formed- How did it form? Write a balanced equation for the formation?
When 5.00 × 1022 molecules of ammonia react with 4.00 × 1022 molecules of oxygen, how many grams of nitrogen gas are produced? 4NH3(g) + 3O2(g) → 2N2(g) + 6H2O(g)
What sequence of steps represents the best synthesis of 4-heptanol (CH3CH2CH2)2CHOH?
Experiment ClO2 (M) OH (M) Rate (M/s) Determine the rate law expression and calculate the value of the rate of constant.
Phenol and straight chain alcohol, The compound C6H5OH is a phelol, and C6H13OH is a straight chain alcohol.
The compound aluminum chloride is widely used to control chemical reactions in industry. It is made by the following reaction: Al2O3(s) + 3C(s) + 3Cl2(g)→ 2AlCl3(s) + 3CO(g)
