In this equation, what should be the coefficients of the reactants and products? I2 + O2 → I4O9

Answers

Answer 1
Answer:

I am thinking that you are asking for the balanced equation for this chemical reaction. In order to balance this, you have to count each element where the elements in the reactants side and the product side should have equal number of molecules. The balanced reaction is as follows:


 2I2 + 9/2O2 → I4O9

Which of the following chemical agents is used for sterilization? a. chlorine b. ethylene oxide c. soap d. phenolics e. alcohol

Answers

Answer:

Ethyleneoxideisthechemicalagentsusedforsterilization.

Final answer:

Ethylene oxide is the chemical agent used for sterilization amongst those listed in the question. This gas sterilizes by disrupting the DNA of microorganisms. Other agents listed, such as chlorine, alcohol and phenolics are generally considered disinfectants, not sterilants.

Explanation:

Out of the chemical agents listed, ethylene oxide is the one commonly used for sterilization. Ethylene oxide is a gas that sterilizes by penetrating and disrupting the DNA of microorganisms, preventing them from reproducing. It is frequently used to sterilize medical and laboratory equipment, particularly items that cannot be sterilized by high heat such as plastic, electrical equipment, and delicate instruments.

While chlorine, alcohol, and phenolics can kill many microorganisms, they are generally considered disinfectants rather than sterilants because they may not kill all types of bacteria, viruses, fungi, and spores. Soap is typically used for cleaning, not specifically for its antimicrobial properties.

Which of the following shows the correct setup in converting 234 kilopascals to torr?

Answers

1 Pascal is equal to 0.008 Torr. So if you have 234 kilopascals, then

234 kilopascals ( 1000 Pascals/ 1 kilopascals) (0.008 Torr / 1 Pascal) = 1,872 Torr

Given the balanced equation:2KClO3==> 2KCl + 3O2
Which type of reaction is represented by this equation?
(1) synthesis
(2) decomposition
(3) single replacement
(4) double replacement

Answers

Answer: Option (2) is the correct answer.

Explanation:

An equation in which the the number of reactants equal the number of products is known as a balanced equation.

Whereas a reaction in which a compound dissociates into two or more compounds is known as a decomposition reaction.

Therefore, the given reaction 2KClO_3 \rightarrow 2KCl + 3O_2 represents that KClO_(3) decomposes into KCl and O_(2).

Hence, it is a decomposition reaction.

Decomposition reaction is the type of reaction that is represented by the given equation. Therefore, the correct option is option 2.

A chemical reaction called a decomposition reaction, often referred to as an analysis or dissociation, occurs when a compound disintegrates into more basic elements. A single compound is transformed into two or more products in this reaction, which may be elements or other compounds.

Decomposition reactions are typically induced by heat, light, electricity, or the presence of a catalyst. These reactions occur because the reactant compound is unstable under certain conditions, leading to its breakdown into more stable products. Therefore, \rm 2KClO_3 \rightarrow 2KCl + 3O_2 is a decomposition reaction.

Therefore, the correct option is option 2.
