False the output force and input force is low because the formula is output force divided by input force. Just a note you are not doing much input force into the screw because you hold the screwdriver

Calculating the expected pH of the buffer solution: Given that the pKa for Acetic Acid is 4.77, calculate the expected pH of the

ser-zykov [4K]

Answer:

$pH=4.77$

Explanation:

From the question we are told that:

pKa for Acetic Acid $pK_a= 4.77$

Therefore

For Equal Concentration of acetic acid and acetatic ion

$CH_3COOH=CH_3COO^-$

Generally the Henderson's equation for pH value is mathematically given by

$pH=pK_a+log\frac{base}{acid}$

$pH=4.77+log\frac{CH_3COO^-}{CH_3COOH}$

$pH=4.77+log1$

$pH=4.77$

A neutralization reaction between an acid and sodium hydroxide formed water and the salt named sodium sulfate. What was the form

myrzilka [38]

Answer: The formula of the acid that was neutralized is $H_2SO_4$

Explanation:

Neutralization is a chemical reaction in which acid and base combine to form salt and water. Acids donate $H^+$ and bases donate $OH^-$ in water which combine to form water molecules.

As the salt formed is $Na_2SO_4$ , the acid must contain $SO_4$ and thus the acid is $H_2SO_4$

The balanced chemical reaction is ;

$H_2SO_4+2NaOH\rightarrow Na_2SO_4+2H_2O$

The formula of the acid that was neutralized is $H_2SO_4$
