Consider the reaction hc2h3o2(aq) h2o(l) → h3o (aq) c2h3o2–(aq). Which species is the conjugate acid?a. C2h3o2-(aq)b. H2o(l)c. H
saul85 [17]

The species that is the conjugate acid is HC₂H₃O₂(aq). The correct option is d.

<h3>What are conjugate acid?</h3>

Conjugates acids are those acids which are made when an acid donates a proton to a base according to Bronsted Lowry theory.

In other words, we can say that it is an acid with hydrogen ion. An example is  water (base) reacting with an acid to form the hydronium ion (conjugate acid).

Thus, the correct option is d, HC₂H₃O₂(aq).

Silver had a density of 10.5 grams per cubic centimeter. What is the mass of 4.0 mL of silver?
Likurg_2 [28]

Explanation:

Given parameters:

Density of silver = 10.5g/cm³

Volume of silver given = 4mL

Unknown:

Mass of silver = ?

Solution:

Density of a substance can be expressed as its mass per unit volume

 Density = \frac{mass}{volume}

 we need to convert our volume to cm³ from mL;

   1cm³ = 1mL

So 4mL = 4cm³

input the values in;

   Mass = density x volume = 10.5 x 4 = 42g
