Answer:
### Equilibrium pressure of H2

### Partial pressure of H2 = 1 + 3x

The **equilibrium pressure** of H2 is **0.96 atm** and the impossible solution of the **quadratic equation** is **-1.379.**

The **equilibrium pressure** of H2 is calculated by creating** ICE table** as follows;

2 N H3 ( g ) ⟷ N2( g ) + 3H2

I: 1 1 1

C: -2x x 3x

E: 1 - 2x 1 + x 1 + 3x

0.83(1 - 2x)² = (1 + x)(1 + 3x)³

0.83(1 - 4x + 4x²) = (1 + x)((1 + 3x)³)

0.83 - 3.32x + 3.32x² = (1 + x)((1 + 3x)³)

0.83 - 3.32x + 3.32x² = 1 + 10x + 36x² + 54x³ + 27x⁴

27x⁴ + 54x³ + 32.68x² + 13.32x + 0.17 = 0

x = -1.379 or - 0.013

H2 = 1 + 3(-1.379)

H2 = -3.13 atm

H2 = 1 + 3(-0.013)

H2 = 0.96 atm

Thus, the **equilibrium pressure** of H2 is **0.96 atm** and the impossible solution of the **quadratic equation** is **-1.379.**

Molecular compounds result from covalent bonding which are called _______.This is for high school physical science

How many molecules are in 2NaO? please someone help i dont know this :')

Refer to the following balance equation : 2c2h6 + 7o2 = 4co2 + 6 h20. How many moles of c2h6 will combust completely with 2.0 moles of oxygen gas. How many grams of water will be produced when 30.0 g of c2h6 reacts completely with oxygen?

Which element is oxidized in the following reaction Mn²⁺ + 2 K → Mn(s) + 2 K⁺ ?

The following reaction was monitored as a function of time: A→B+C A plot of ln[A] versus time yields a straight line with slope −4.3×10−3 /s. If the initial concentration of A is 0.260 M, what is the concentration after 225 s?

**Answer:**

The correct answer is **the tendency of all the elements to react with every other element. **

**Explanation:**

A component in which two or more elements are bonded chemically leads to the production of a compound. A compound refers to a pure component as it comprises elements that are in their pure state. The formation of a compound takes place when the elements react with each other based upon their reactivity.

For example, the element chlorine is deficient of one electron and the element sodium exhibits one additional electron. Thus, chlorine easily reacts with the sodium in order to obtain stability. Therefore, the formation of sodium chloride takes place. Hence, it can be concluded that the tendency of all the elements to react with every other element is the condition, which is possible to influence the probable number of compounds.

the impact of possible number of compounds is the ability of all elements to react with every other atoms

Given Mass of pure silver (Ag) = 265 mg

Silver chloride AgCl which is used in plating silver contains 75.27 % Ag

This means that:

A 100 mg of silver chloride contains 75.27 mg of silver

Therefore, the amount of silver chloride required to plate a sample containing 265 mg silver would correspond to:

265 mg Ag * 100 mg AgCl/75.27 mg Ag

= 352.1 mg AgCl

**Answer:**

**0.35215 grams of silver chloride required to plate 265 mg of pure silver.**

**Explanation:**

Mass of silver = 265 mg = 0.265 g

Moles of silver =

According to reaction, 2 moles of silver are obtained from 2 moles of silver chloride.

Then 0.002454 moles of silver will be obtained from :

of silver chloride

Mass of 0.002454 moles of silver chloride:

= 0.002454 mol × 143.5 g/mol = 0.35215 g

**0.35215 grams of silver chloride required to plate 265 mg of pure silver.**

**Answer:**

c. CH3CH2CH(CH3)CHO

**Explanation:**

Hello there!

In this case, according to the process for the one-step oxidation of a primary alcohol with a moderately strong oxidizing agent like pyridinium chlorochromate (PCC), whereby an aldehyde is produced, we infer that the corresponding product will be 2-methylbutanal, which matches with the choice c. CH3CH2CH(CH3)CHO according to the following reaction:

**Answer:**

0.113 M

**Explanation:**

Since B and D are on opposite sides of the reaction, the concentration of D increases when the concentration of B decreases. The amount by which D increases is determined by the coefficients of B and D in the balanced chemical equation:

[D]=(0.045 M)=0.113 M.
