Answer:

Kp of the reaction is 0.0215

Explanation:

Step 1: Data given

Partial pressure at the equilibrium of N2 = 0.22 atm

Partial pressure at the equilibrium of O2 = 0.19 atm

Partial pressure at the equilibrium of NO = 0.030 atm

Temperature = 2200 °C

Step 2: The balanced equation

N2(g) + O2(g) ⇌ 2NO(g)

Step 3: Calculate Kp

Kp = (pNO)² /(pO2)*(pN2)

Kp = (0.030)²/(0.19*0.22)

Kp = 0.0215

Kp of the reaction is 0.0215

Natural gas or methane is a fossil fuel. In a plentiful supply of air, it burns to give carbon dioxide and water. Write a balanc

Alex17521 [72]

Answer:

$CH_4 + 2O_2 --> CO_2 + 2H_2O$

Explanation:

The chemical formula for methane is $CH_4$

The chemical formula for oxygen is $O_2$

The chemical formula for carbon dioxide is $CO_2$

The chemical formula for water is $H_2O$

Methane burns in oxygen to give carbon dioxide and water:

$CH_4 + O_2 --> CO_2 + H_2O$

The balanced equation that will ensure an equal number of each atom on the left and right-hand sides of the equation would be:

$CH_4 + 2O_2 --> CO_2 + 2H_2O$

Name two "Storage Polysaccharides" and two "Structural Polysaccharides"

Vsevolod [243]

Answer:

Examples of storage polysaccharides - <u>starch and glycogen</u> and structural polysaccharides - <u>cellulose and chitin</u>

Explanation:

Polysaccharides are the complex carbohydrate polymers, composed of monosaccharide units that are joined together by glycosidic bond.

In other words, polysaccharides are the carbohydrate molecules that give monosaccharides or oligosaccharides on hydrolysis.

The examples of storage polysaccharides are starch and glycogen. The examples of structural polysaccharides are cellulose and chitin.

In a reaction, 5.3g of Sodium Carbonate reacted with 6g of ethanoic acid. The products were 2.2g of CO2, 0.9g of water and 8.2g

V125BC [204]

SOLUTION :

Law of conservation of Mass States that "Mass is neither created, nor destroyed".

→ Like Mass of Reactants = Mass of products.

REACTANTS :

Mass of Sodium Carbonate(given) = 5.3g

Mass of ethanoic acid(given)= 6g

The total mass of reactants:

= 5.3 + 6

= 11.3g

<h3>•Products are :</h3>

Mass of Carbon Dioxide = 2.2g

Mass of Water = 0.9g

Mass of Sodium ethanoate = 8.2g

The total mass of products is :

= 2.2 + 0.9 + 8.2

= 3.1 + 8.2

= 11.3g

Hence the, Mass of Reactants = Mass of products

∴ The given reaction is in agreement with the law of conservation.
