A single drop of soda contains how many atoms?

Chemistry
1 answer:
Natalija [7]3 years ago
6 0
Since we are not given with any quantitative information, we have to rely on literature data. Suppose the soda drink referred to here is Coke. The density of a Coke at 20°C is 0.995 g/mL. A single drop of liquid is approximately 0.05 mL. From these two data, we can determine the mass of coke in a single drop.

Mass = 0.995 g/mL * 0.05 mL = 0.04975 g

We have to know the molar mass of Coke. Since majority of it is composed of sugar sucrose, let's take the value of the molar mass of sucrose: 342.2965 g/mol. Using the Avogadro's number (6.022×10²³ atoms/mol),

Number of atoms = 0.04975 g * (1 mol/342.2965 mol) * (6.022×10²³ atoms/mol) = 8.75×10¹⁹ atoms

Imagine the reaction A + B ⇌ C + D is at equilibrium, where the forward and reverse reactions are at equal rates. What would hap
kondaur [170]

Answer:

Rate of forward reaction will increase.

Explanation:

Effect of change in reaction condition on equilibrium is explained by Le Chatelier's principle. According to this principle,

If an equilibrium condition of a dynamic reversible reaction is disturbed by changing concentration, temperature, pressure, volume, etc,  then reaction will move will in a direction which counteract the change.

In the given reaction,

A + B ⇌ C + D

If concentration of A is increase, then reaction will move in a direction which decreases the concentration of A to reestablish the equilibrium.

As concentration A decreases in forward direction, therefore, rate of forward reaction will increase.

When an aqueous solution containing hydrochloric acid is just neutralized with an aqueous solution containing sodium hydroxide,
Elza [17]

Answer:

c. salty.

Explanation:

From the question,

The reaction of an acid , i.e hydrochloric acid and a base i.e. , sodium hydroxide takes place , which is a type of neutralization reaction,

Where the acid and a base reacts to give salt along with water .

From the question,

The reaction is as follows -

2 HCl  +  NaOH  →  NaCl  +  H₂O  

Hence, the resulting product is a salt ,

Therefore , the resulting solution would taste like salt.

A block of iron has a mass of 150 g and a volume of 20 ml. What is the density of iron? *
shtirl [24]

Answer:

<h3>The answer is 7.50 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass of iron = 150 g

volume = 20 mL

We have

density =  \frac{150}{20}  =  \frac{15}{2}  \\

We have the final answer as

<h3>7.50 g/mL</h3>

Hope this helps you
