Answer:

Due to deficiency of Oxygen in atmosphere.

Explanation:

Oxidation is defined in two ways, 1) The addition of Oxygen and Removal of Hydrogen 2) The removal of electrons.

We will discuss the first definition for this question. The addition of oxygen to various compounds results in the oxidation of that compound.

Example: Oxidation of Methane;

CH₄ + 2 O₂ → CO₂ + 2 H₂O

In this example oxygen is added to methane and hydrogen is being removed from methane.

Oxidation type chemical weathering common more than 2 billion years ago because of less amount of Oxygen in atmosphere and the oxygen which was produced by plants reacted with different metals like Iron forming precipitates which precipitated to the bottom of oceans.

When dilute HCL is added to zinc pieces taken in a test tube

Romashka-Z-Leto [24]

Answer:

zince chloride will be formed and hydrogen gas will be librated.

Explanation:

When dilute HCl is added to zinc pieces, a rection will takes place as follows :

$Zn+HCl\rightarrow ZnCl_2+H_2$

It means that zinc chloride will form when zinc reacts with dilute HCL. Also hydrogen gas will produced.

As zinc is more reactive than hydrogen, it displaces hydrogen from its solution and forms zinc chloride. The form product is white in color and H₂ is an odorless gas.

Hence, zince chloride will be formed and hydrogen gas will be librated.

When baking soda (NaHCO3) is heated, it decomposes, producing carbon dioxide, water, and sodium carbonate. The carbon dioxide is

11Alexandr11 [23.1K]

Answer:

mass of carbon-dioxide = 0.262 g

Explanation:

Firstly, write the chemical equation of the reaction and balance the equation accordingly.

2NaHCO3(aq) → CO2(g) + H2O(l) + Na2CO3(aq)

Calculate the molecular mass of baking soda

molar mass of baking soda = 23 + 1 + 12 + 48 = 84 g

2 moles of baking soda = 2 × 84 = 168 g

molar mass of CO2 = 12 + 32 = 44 g

if 168 g of baking soda produces 44 g of carbon-dioxide

1 g of baking soda will produce ? grams of carbon-dioxide

cross multiply

mass of carbon-dioxide = 44/168

mass of carbon-dioxide = 0.2619047619

mass of carbon-dioxide = 0.262 g
