Is there an easy way to remember how to tell what the significant figures are.
Suppose that it is a hot summer day (40 degrees C= 104 degrees F),
and you have left a can of hairspray outside so the gas within it is now at the same temperature as its surroundings. As part of your chemistry lab class you have to build a safe and effective potato gun to share with the local elementary school, and you must be sure that the combustion chamber is well insulated and will not harm (burn) the shooter. You spray the warm hairspray into a 3.50 L chamber on your gun, You seal the cap, then ignite it, and the resulting gas expands to 13.0 L as the potato is shot out. What is the final temperature in Celsius, inside the combustion chamber? what is the temperature in Fahrenheit? must show all work
Remember that an acid is something that donates hydrogen ions. So, when considering the formula HC232
HO(acetic acid), which of the hydrogens listed are the ones that ionize (fall apart into solution as hydrogen ions)?
`On the pH scale, the value of 7 is a key point on the scale. If a solution has this pH, then
Suppose you have a 0.0170L sample of H2SO4 of unknown concentration.
If this amount of H2SO4 is used to exactly titrate 0.0450L of NaOH that has a concentration of 0.235 M, what is the molarity of the H2SO4? Hint: H2SO4(aq)+2NaOH(aq)—- 2H2O(l)+Na2SO4(aq)
