Answer:

Kp = (Partial pressure H₂O) . (Partial Pressure Cl₂)² / Partial pressure O₂ . (Partial Pressure HCl)⁴

Explanation:

This is the reaction:

4 HCl (g) + O₂ (g) ⇒ 2 Cl₂ (g) + 2 H₂O(g)

Kp = (Partial pressure H₂O) . (Partial Pressure Cl₂)² / Partial pressure O₂ . (Partial Pressure HCl)⁴

Answer:

Kp = ((pH2O)²*(pCl2)²] /((pO2)(pHCl)^4)

Explanation:

Step 1: data given

Hydrogen chloride = HCl

oxygen = O2

chlorine = Cl2

water = H2O

Step 2: The balanced equation

4 HCl(g)+O2(g) ⇒ 2 Cl2(g)+2 H20(g)

Step 3: Define the pressure equilibrium constant

Kc = [[H2O]²*[Cl2]²] /[[O2][HCl]^4]

Kp = ((pH2O)²*(pCl2)²] /((pO2)(pHCl)^4)

⇒ with pH2O = the partial pressure of H2O

⇒ with pCl2 = the partial pressure of Cl2

⇒ with pO2 = the partial pressure of O2

⇒ with pHCl = the partial pressure of HCl

This particle determines what element you have - the element's identity.

scoundrel [369]

Answer:

protons

These particles do not vary in quality from one element to another; rather, what gives an element its distinctive identification is the quantity of its protons, called its atomic number. Protons and neutrons contribute nearly all of an atom's mass; the number of protons and neutrons is an element's mass number

Rewrite and Balance the Equation <br> N₂ + H₂ -> NH3

Mars2501 [29]

Answer:N

+ 3

-----> 2N

Explanation:

-----> N

Let us balance this equation by counting the number of atoms on both sides of the arrow.

-----> N

N=2 , H=2 N=1, H=3

To balance the number of N atom on Right Hand Side (RHS) , I will add one molecule of N

on RHS

-----> 2N

N=2 , H=2 N=2 , H= 6

To balance the number of H atoms on Left Hand Side (LHS) , I will add two molecules of

on LHS

+ 3

-----> 2N

N=2 , H=6 N=2 , H= 6

What is the kinetic evidence for SN1 reaction

inn [45]

Answer:

In doubling the concentration of the alkyl halide, the reaction rate also increases two-fold. However, doubling the concentration of the nucleophile does not in any way alter the reaction rate. Thus, the reaction rate is proportional only to the alkyl halide's concentration.

in rutherford's gold foil experiment a very small number of alpha particles were deflected. what about the structure of the atom

zvonat [6]

Answer:The atom being mostly empty space. A small number of alpha particles were deflected by large angles (> 4°) as they passed through the foil. There is a concentration of positive charge in the atom. Like charges repel, so the positive alpha particles were being repelled by positive charge

Three mixtures were prepared from three very narrow molar mass distribution polystyrene samples with molar masses of 10,000, 30,

8_murik_8 [283]

Answer:

(a). 46,666.7 g/mol; 78,571.4 g/mol

(b). 86950g/mol; 46,666.7 g/mol.

(c). 86950g/mol; 43,333.33 g/mol

Explanation:

So, we are given the molar masses for the three samples as: 10,000, 30,000 and 100,000 g mol−1.

Thus, the equal number of molecule in each sample = ( 10,000 + 30,000 + 100,000 ) / 3 = 46,666.7 g/mol.

The average molar mass = [ ( 10,000)^2 + (30,000)^2 + 100,000)^2] ÷ 10,000 + 30,000 + 100,000 = 78,571. 4 g/mol.

(b). The equal masses of each sample = 3/[ ( 1/ 10,000) + (1/30,000 ) + (1/100,000) ] = 20930.23 g/mol.

Average molar mass = ( 10,000 + 30,000 + 100,000 ) / 3 = 46,666.7 g/mol.

(c). Equal masses of the two samples = (0.145 × 10,000) + (0.855 × 100,000)/ 0.145 + 0.855 = 86950g/mol.

The weight average molar mass = 1.7 + 10,000 + 100,000/ 1.7 + 1 = 43,333.33 g/mol.
