An Arrhenius acid is a compound that increases the H + ion concentration in aqueous solution. The H + ion is just a bare proton, and it is rather clear that bare protons are not floating around in an aqueous solution.

Explanation:

An Arrhenius acid is any species that increases the concentration of H+start text, H, end text, start superscript, plus, end superscript in aqueous solution. An Arrhenius base is any species that increases the concentration of OH−start text, O, H, end text, start superscript, minus, end superscript in aqueous solution.

Ierofanga [76]

Answer:

$3.6\times 10^{-4}$ moles of Threobromine are present in chocolate bar

Explanation:

Molar mass of Theobromine = ( $7\times$ molar mass of C)+( $8\times$ molar mass of H)+( $4\times$ molar mass of N)+( $2\times$ molar mass of O) = ( $7\times$ 12g/mol)+( $8\times$ 1g/mol)+( $4\times$ 14g/mol)+( $2\times$ 16g/mol) = 180 g/mol

We know that, number of moles of a compound is the ratio of mass to molar mass of the compound.

So, 0.064 g of Threobromine = $\frac{0.064}{180}$ moles of Threobromine = $3.6\times 10^{-4}$ moles of Threobromine

babunello [35]

Answer:

(A.) CO2, H2O

Explanation:

The chemical equation for respiration process is:

$C_{6}H_{12} O_{6}$ + $6O_{2}$ → $6CO_{2}$ + $6H_{2} O$ + ATP↑

Energy is released during the biochemical process in the organism's cells in form of ATP. Byproducts of the reaction are carbon dioxide and water molecules.
