<span><span>Tony Buzan is a world famous expert on ways of developing the mind
and intelligence. His latest book is called “Head First” – 10 ways to tap into
your natural genius. A few years ago, Buzan started to think about the topic of
intelligence but couldn’t (1) <u>work out </u>why some so-called “intelligent” people did not seem very bright, while others who failed to (2) get …</span></span><span>through…. exams appeared much more intelligent. Buzan (3) got…</span><span>down…. to work on this and eventually (4) came …</span><span><span>up…. with the ideas in his book. </span>
His starting point is that everyone can do well if they get rid of the barriers put up by the way they were educated and (5) brought …up…. .The first step is to boost your belief in yourself. Buzan’s performance in Maths (6) went …up…. a lot when he (7) found …</span><span>out…. he was in the top 1 percent of all mathematicians. Secondly, it is important to realize that ability is not something only for the talented few. For example, we are (8) put …off…. singing because we feel we haven’t got the “gift” but in fact we “sing” all the time when we speak a language. His third lesson is that all of us are intelligent.
“There is only one intelligence test”, he says, ”and that is life on planet
Earth. Every day we are faced with new problems that we learn to handle”.
In the book, you can (9) go …</span><span><span>through</span>…. a series of activities which will
change your perception of how intelligent you are. Personally, I (10) got a lot
…out…. of this book and would recommend it to anyone.

Buffer solutions, depending on their composition, are divided into 2 main types:
acidic and basic.
Acid buffering systems are usually formed by a weak inorganic or
organic acid and a salt of the same acid with a strong base.
For example:
1) CH3COOH + CH3COONa - acetate buffer
weak acid salt acid
2) H2CO3 (H2O + CO2) + NaHCO3 - hydrocarbonate or
weak acid salt acid bicarbonate buffer.
Basic buffer systems are formed by weak inorganic or
organic base and a salt of this base with a strong acid. For example:
1) NH3 · H2O (NH4OH) + NH4Cl - ammonia buffer
weak base salt
2) C2H5 – NH2 + C2H5NH3Cl - ethylamine buffer
weak base salt
Basic buffer systems are formed by weak inorganic or
organic base and a salt of this base with a strong acid. For example:
1) NH3 · H2O (NH4OH) + NH4Cl - ammonia buffer
weak base salt
2) C2H5 – NH2 + C2H5NH3Cl - ethylamine buffer
weak base salt.
