Irina18 [472]3 years ago
7 0

Answer:

22 mol

Explanation:

Given data:

Number of atoms of Cl = 2.65×10²⁵ atom

Number of moles of Cl = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

2.65×10²⁵ atom × 1 mol / 6.022 × 10²³ atoms

0.44×10² mol

22 mol

Calculate the density of 30 cubic centimeters of liquid that has a mass of 120 grams.
-BARSIC- [3]

Answer:

<h2>4 g/cm³</h2>

Explanation:

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

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

From the question we have

density =  \frac{120}{30}  =  \frac{12}{3}  \\

We have the final answer as

<h3>4 g/cm³</h3>

What is e cell (in units of volts) for a galvanic cell constructed from barium and manganese electrodes?
gulaghasi [49]

Main Answer: The standard electrode potential of galvanic cell constructed from barium and manganese electrode is 4.097.

Explanation:

When the galvanic cell constructed between Manganese and Barium, the half reactions will be as follows:

Mn2+(aq) + 2e-⟶ Mn(s)                                             E1 = −1.185

Ba2+(aq) + 2e-⟶ Ba(s)                                                 E2 = −2.912

By considering the above two reactions, the standard electrode potential can be calculated.

The galvanic cell standard electrode potential is given by E1 + E2 = 1.185 + 2.912 = 4.097 volts

What is standard electrode potential?

Standard electrode potential is defined as the measure of reducing power of any compound or element. Its units are volts.

Which of the following is/are true concerning a chemical reaction at equilibrium? 1. The system will be a mixture of reactant an
maks197457 [2]

Answer: Option (e) is the correct answer.

Explanation:

An equilibrium reaction is defined as the reaction where rate of forward reaction will be equal to the rate of backward reaction.

For example, N_{2}(g) + 3H_{2}(g) \rightleftharpoons 2NH_{3}(g)

So, here amount of reactants that is, nitrogen gas and hydrogen gas  will be constant along with constant amount of formation of product that is, ammonia here.

In an equilibrium reaction there is presence of both reactants and products and hence, both reactants and products constitute the system.

Thus, we can conclude that all the given statements are true.
