9.17 milliliters (mL) of the acid are needed to completely neutralize the base in this reaction.

<h3>What is a neutralization reaction</h3>

A neutralization reaction is a reaction between an acid and a base to produce a salt and water only.

The process of reacting given volume of acids or bases to determine the concentration or volume of either the acid or base required for neutralization is known as titration in volumetric analysis.

The formula to determine the volume of the acid required is given below:

\frac{C_{a}V_{a}}{C_{b}V_{b}} = \frac {N_{a}}{N_{b}}

where V_{a is the volume of acid required

V_{a} = \frac {C_{b}V_{b}N_{a}}{C_{a}N_{b}}

Concentration of base, Cb = (3.51/74)/0.75 = 0.063 M

Vb = 50. 0 mL

Ca = 0.229 M

Na = 2

Nb = 3

Va = (0.063 * 50 * 2)/(0.229 * 3)

Va = 9.17 mL

In conclusion, the volume of the acid is determined from the concentration, volume and mole ratio of the reaction.

Describe the temperature changes that occur in ice as energy is added, starting in the frozen state and ending in the vapor stat
Ket [755]

Explanation:

When water is frozen then it is known as ice and its state is solid. So, its molecules will be held closer to each other as they are held by strong intermolecular forces of attraction.

As a result, its temperature will be minimum as its molecules have least kinetic energy.

It is known that kinetic energy of a substance is directly proportional to temperature.

As,            K.E = \frac{3}{2}kT

where            K.E = kinetic energy

                       T = temperature

                       k = boltzmann constant

When solid changes into liquid state then it means molecules of a substance has gained kinetic energy due to which there occurs more collisions between the molecules.

Hence, temperature of substance also increases.

Whereas when liquid state of a substance changes intro vapor state then it means that more kinetic energy has gained by the molecules due to which there will be much more collisions between the molecules.

Hence, temperature will be maximum in vapor state.

How many grams of sulfur are needed to react completely with 246 g of mercury to form hgs?
iren [92.7K]

The reaction between mercury (Hg) and sulfur (S) to form HgS is:

Hg + S ------------- HgS

Therefore: 1 mole of Hg reacts with 1 mole of S to form 1 mole of HgS

The given mass of Hg = 246 g

Atomic mass of Hg = 200.59 g/mol

# moles of Hg = 246 g/ 200.59 gmol-1 = 1.226 moles

Based on the reaction stoichiometry,

# moles of S that would react = 1.226 moles

Atomic mass of S = 32 g/mol

Therefore, mass of S = 1.226 moles*32 g/mole = 39.23 g

39.2 g of sulfur would be needed to react completely with 246 g of Hg to produce HgS

Which of the following observations would indicate that a material is a pure substance?
Ira Lisetskai [31]
<span>The answer to the question is the option C. it cannot be physically broken down into different types of atoms. This means that the material is an element, which is a pure substance. Because an element is a pure substance that is formed by one only type of atoms. For example, gold is an element and all its atoms are of the same type. That is also true for any of the 118 elements of the periodic table. Compounds (other kind of pure substances) can be broken down into molecules (which contain different kind of atoms, but always in the same proportion) and mixtures (non pure substances) have different kind of substances.</span>
