The mass of a coin : 2.2613 g
<h3>Further explanation </h3>Algebraic expressions in mathematics are a combination of coefficients, numbers, variables, constants and arithmetic operations such as addition, subtraction, multiplication, and division.
The main composition of algebraic expressions are:
algebraic forms separated by arithmetic operations
consists of one phrase (monomial) to many phrases (polynomial)
is a value that can be changed, can be in the form of letters, for example, x, y, a, b, etc.
is a fixed value, can be a number
<em>If 100 coins have a total mass of 226.13g. What is the mass of a coin</em>
We can make this statement in the form of an algebraic equation :
100 coins=226.13 g
then the mass of a coin :
Conjugate base of Propanoic acid ( is propanoate where -COOH group gets converted to -CO
. The structure of conjugate base of Propanoic acid is shown in the diagram.
The above which 90% of the compound will be in this conjugate base form can be determined using Henderson's equation as propanoic acid is weak acid and it can form buffer solution on reaction with strong base.
=
+ log
=4.9+log
=5.85
As 90% conjugate base is present, so propanoic acid present 10%.
