Answers

Answer 1

Balancing the given equation we find that it will be equal to:

[tex]3NaHCO_3+H_3C_6H_5O_7 \rightarrow Na_3C_6H_5O_7+3H_2O+3CO_2[/tex]

What does balancing chemical equations mean?

Reaction balancing is a method used in several areas of Chemistry to determine the amount of matter of each of the substances participating in the reaction, as well as to establish the existing proportions between the components.

Then the equation before performing the balancing is given by:

[tex]NaHCO_3+H_3C_6H_5O_7 \rightarrow Na_3C_6H_5O_7+H_2O+3CO_2[/tex]

For this equation to become balanced it will be necessary that:

On the right side of the equation we have more Na and H so it will be necessary to multiply by 3

So the balanced equation will be:

[tex]3NaHCO_3+H_3C_6H_5O_7 \rightarrow Na_3C_6H_5O_7+3H_2O+3CO_2[/tex]

Based on the literature of east Asia and the pacific rim, I do agree  with Kipling's statement.

What is the statement about?

The famous line of Rudyard Kipling "East is east and west is west and never the twain shall meet".

From the line above, we can see that he declares his love for British Colonialism and as such, I can say I believe in India and it tells one that the people of the east India and the people of Britain are said to be mutually exclusive.

In this case, they will not be able to reconcile their differences and the assumption is seen as white colonialists are more superior to the Indian  people.

In "The Literature of East Asia and the pacific rim" Michael Harris quotes "oh east is east, and west is west, and never the twain shall meet".
