Answer:

0.718L of 0.81M HCl are required

Explanation:

Based on the reaction:

Cd(s)+2HCI(aq) → H2(g)+CdCl2(aq)

<em>1 mol of Cd reacts with 2 moles of HCl</em>

<em />

To solve this question we must, as first, find the moles of Cd. With the moles of Cd we can find the moles of HCl needed to react completely with the Cd. With the moles and the molarity we can find the volume:

<em>Moles Cd -Molar mass: 112.411g/mol-:</em>

32.71g * (1mol / 112.411g) = 0.2910 moles Cd

<em>Moles HCl:</em>

0.2910 moles Cd * (2 moles HCl / 1mol Cd) =

0.5820 moles HCl

<em>Volume:</em>

0.5820 moles HCl * (1L / 0.81moles) =

<h3>0.718L of 0.81M HCl are required</h3>

The concentration of hydronium ions is greater than 1 × 10–7 for basic solutions. True False
Nataly [62]

Answer : The given statement is, false.

Explanation :

Ionic product of water : It is defined as the product of the concentration of hydrogen ion and the concentration of hydroxide ion.

The mathematical expression will be,

[H^+][OH^-]=10^{-14}

When the concentration of hydrogen ion and hydroxide ion are equal then the solution is neutral and the value will be, 1\times 10^{-7}. And the pH of the solution is, 7.

When the concentration of hydrogen ion is greater than 1\times 10^{-7} then the solution is acidic in nature. And the pH of the solution is, less than 7.

When the concentration of hydrogen ion is less than 1\times 10^{-7} then the solution is basic in nature. And the pH of the solution is, greater than 7.

Hence, the given statement is false.
