BARSIC [14]

Answer:

HClO4(aq) + H2O(l) ⇄ H3O+(aq) + ClO4-(aq)

Explanation:

When an acid dissolves in water, it will produce hydronium ion, H3O+ as the only positive ion.

perchloric acid, HClO4, being an acid will react with water, H2O to produce hydronium ion, H3O+ as shown below:

HClO4(aq) + H2O(l) ⇄ H3O+(aq) + ClO4-(aq)

What is the balanced equation for the manufacture of ethanol from glucose
Darina [25.2K]

Answer:

C6H12O6 → 2C2H5OH + 2CO2

Explanation:

Glucose is an organic molecule, specifically a sugar, with the formula C612O6 while ethanol is another organic molecule with formula; C2H5OH.

However, as rightly said in this question, ethanol can be got from glucose via a process called fermentation in the presence of a catalyst called YEAST. The balanced equation is as follows:

C6H12O6 → 2C2H5OH + 2CO2

A sample was then prepared containing 14.00 mL of coffee and 8.00 mL of 4.80 ppm Li , and diluted to a 50.00 mL total volume. Th
mafiozo [28]

Answer:

The right answer is "[Na^+]=5.57 \ ppm".

Explanation:

The given values are:

\frac{A_s}{A_{coffee}} =\frac{0.840}{1.000}

According to the question,

The concentration of standard will be:

=  \frac{7.80}{50.00}\times 4.80

=  0.156\times 4.80

=  0.748 \ ppm

Coffee after dilution,

⇒  \frac{A_{coffee}}{C_{coffee}} =F\times \frac{A_s}{C_s}

or,

⇒  C_{coffee}=\frac{A_{coffee}}{A_s}\times \frac{C_s}{F}

On substituting the values, we get

⇒               =\frac{1.000}{0.840}\times \frac{0.748}{1.68}

⇒               =1.191\times 1.3104

⇒               =1.561 \ ppm

hence,

In unknown sample, the concentration of coffee will be:

=  1.561\times \frac{50}{14}

=  \frac{78.05}{14}

=  5.57 \ ppm
