What type of chemical reaction is Ba(ClO3)2 --> BaCl2 + O2.

1 answer:

3 0

$(Ba(ClO_3)_2)$ → $BaCl_2 + O_2$ is a decomposition reaction. Barium chlorate $(Ba(ClO_3)_2)$ decomposes to give barium chloride and oxygen.

<h3>What is decomposition reaction?</h3>

A decomposition reaction can be defined as a chemical reaction in which one reactant breaks down into two or more products.

A decomposition reaction produces multiple products from a single reactant.

Combustion reactions are the combination of some compound with oxygen to make oxides of the other elements as products.

Hence, $(Ba(ClO_3)_2)$ → $BaCl_2 + O_2$ is a decomposition reaction. Barium chlorate $(Ba(ClO_3)_2)$ decomposes to give barium chloride and oxygen.

borishaifa [10]

Answer:

12 grams

Explanation:

D = m/V

0.5g/ $cm^3$ = m/(2*3*4)

$\frac{0.5g}{cm^3} = \frac{m}{24cm^3}$

m = 12g

Be sure to answer all parts. Consider the following balanced redox reaction (do not include state of matter in your answers): 2C

timurjin [86]

Answer:

The specie which is oxidized is:- $CrO_2^-$

The specie which is reduced is:- $ClO^-$

Explanation:

Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

$X\rightarrow X^{n+}+ne^-$

Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

$X^{n+}+ne^-\rightarrow X$

For the given chemical reaction:

$2CrO_2^- + 6ClO^- + 2H_2O\rightarrow 2CrO_4^{2-} + 3Cl_2 + 4OH^-$

The half cell reactions for the above reaction follows:

Oxidation half reaction: $CrO_2^- + 2H_2O + 4OH^-\rightarrow CrO_4^{2-} + 4H_2O + 3e^-$

Reduction half reaction: $2ClO^- + 4H_2O + 2e^-\rightarrow Cl_2 + 2H_2O + 4OH^-$

Thus, the specie which is oxidized is:- $CrO_2^-$

The specie which is reduced is:- $ClO^-$

Knowing the molarity of a solution is more meaningful than knowing whether a solution is dilute or concentrated. explain.

ser-zykov [4K]

Molarity is a measure of a solution's concentration calculation by getting the ratio of the number of moles of solute to the total volume of solution. This has a unit of M or molar, equivalent to mole/L.

It is more important and meaningful to know the molarity rather than if the solution is dilute or concentrated because molarity gives the QUANTITATIVE approach of knowing the concentration while the second one only gives us the QUALITATIVE description of the solution. Hence, we are able to calculate for other unknown parameters if we have the molarity known.

Products made of plastic can last a very long time. Explain both the positive and negative effects of plastic being long-lasting

Vinil7 [7]

Because plastic products are durable, they can last for a long time. This makes them affordable because they do not have to be replaced often. On the other hand, the popular use of plastics means that many plastics are thrown away. Plastics litter the ocean, causing harm to marine birds and mammals. Plastic breaks down into plastic dust, which can last for up to a thousand years.
