What type of reaction produces a metal from its metal oxide

Answers

Answer 1

Answer:

Metal oxides M2O, peroxide M2O2, and superoxide MO are produced by alkali metals. Metal oxide is also referred to as basic oxide since basic hydroxide is the end result of interactions between metal oxide and water. As a result, their combination with acid produces salt and water in a manner similar to a regular acid-base reaction.

What is metal oxide ?

One of the most significant and well-characterized solid catalysts is metal oxide. Metal oxides are used in acid-base and redox processes and are regarded as heterogeneous catalysts.

Several metals are separated from their naturally occurring compounds like oxide and chloride using a breakdown reaction.

Metal oxides are crucial in various additional applications, such as energy production, conversion, and storage, as well as in environmental remediation and pollution monitoring.

Because they react with weak acids to produce salt and water, metallic oxides are basic in nature. They further react with water to create metal hydroxides, which are naturally alkaline due to the production of OH- ions in solution.

Thus, Metal oxides M2O, peroxide M2O2, and superoxide MO are produced by alkali metals.

How many moles of oxygen will be released when 250.0 grams of KClO3 is thermally decomposed ? 2KClO3 --> 2KCl+3O2<br /><br /> (Must be made to fit into this chart)

Answers

Molar mass KClO₃ = 122.5 g/mol and O₂ = 32.0 g/mol

2 KClO₃ ----------------> 2 KCl + 3 O₂

2 * 122.5 g KClO₃ ---------> 3 * 32 g O₂
250.0 g KClO₃ ------------> ?

mass of O₂ = 250.0 * 3 * 32 / 2 * 122.5

mass of O₂ = 24000 / 245

mass of O₂ = 97.959 g

number of moles O₂ :

1 mole --------- 32.0 g
? mole -------- 97.959 g

moles = 97.959 * 1 / 32.0

= 97.959 / 32.0

= 3.061 moles of O₂

How many grams of O2(g) are needed to completely burn 73.7 g of C3H8(g)?

Answers

The balanced reaction is:

C3H8 + 5O2 = 3CO2 + 4H2O

We are given the amount of C3H8 to be reacted with O2. This will be the starting point of the calculations.

73.7 g C3H8 ( 1 mol C3H8/ 44.1 g C3H8 ) ( 5 mol O2 / 1 mol C3H8 ) ( 32.0 g O2 / 1 mol O2 ) = 267.39 g O2

Answer: 267.2 grams

Explanation:

$C_3H_8+5O_2\rightarrow 3CO_2+4H_2O$
