So the concentration of HCl you computed was of the true value, 0.120 M. A graph of Titration of H C l with N a O H has volume N a O H titrated on the horizontal axis and p H of mixture on the vertical axis, ranging from 0 to 14 in units of 2. 5 orange dots lie along the beginning of a line that runs along the horizontal axis, and curves sharply up as it reaches the last dot through a point labeled equivalence point p H 7, and continues to rise sharply before starting to level off at about 12 on the p H scale, where it runs through 5 more red dots. A dotted line runs across the graph at 8.2 on the p H scale. slight overestimate

answer carbon and three oxygen atoms;

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
