A student titrates 60.0 mL of HNO3(AQ) with 0.30 M NaOH(AQ). Phenolphthalein is used as the indicator.
After adding 42.2 mL of NaOH(AQ), a color change remains for 25 seconds, and the student stops the
titration. Write a balanced equation and calculate the molarity of the of HNO3(AQ), with sig figs and units

explanation:

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
