Answer:
4.52 x 10²⁴ atoms Cl
Explanation:
A mole is a name that means a certain number like a dozen means 12. 1 mole of chlorine atoms is 6.022 x 10²³ chlorine atoms. The unit conversion is 6.022 x 10²³/mol.
Round to 4.52 x 10²⁴ atoms Cl for the correct number significant figures.
Answer:
False
Explanation:
It is not true that this is an example of a chemical reaction. This is a typical example of physical reaction.
Most physical changes are often phase changes.
- A phase change is a change in the physical state of a body.
- In this change, it is from solid to liquid.
- Now new substances are formed.
- When substances are changed from one form to another, it is a physical change.
In a chemical change, a new substance is formed at the end of the process.

Explanation:
You are not really helped by what is hold the liquid. Beakers and cylinders come on a lot of sizes. I hate to be crabby about things like that, but you really need to be aware that the question is slightly flawed (not your fault).
The beaker, you'd be like to get 1 sig digit. You have to be awfully careful about claiming more. So the and is 50 mL, but that mL is a guess and the 50 is not totally accurate, but what would you say the second digit is? 48 or 47? You don't really know. Maybe even 49.
The graduated cylinder is a little better. Read the bottom of the meniscus (the bottom of the 1/2 bubble). I think you can get 2 sig digs., so the answer is 36 mL. But everything also depends on what you have been told.
Chemical symbols are represented with their coefficients in a balanced reaction. Ethane and oxygen are the reactants, whereas carbon monoxide and water are the products.
4 HCl (g) + O₂ (g) → 2 Cl₂ (g) + 2 H₂O (l)
<h3>What is Carbon monoxide?</h3>
Carbon monoxide, a colorless, incredibly lethal, odorless, tasteless, and flammable gas with the chemical formula CO, is a little less dense than air. Carbon monoxide is a compound made composed of one carbon atom and one oxygen atom joined by three bonds. This is the simplest molecule in the oxocarbon family. The term "carbonyl" refers to the carbon monoxide ligand in coordination complexes. It is an essential part of many industrial chemistry procedures.
Carbon monoxide plays important biological roles in all phylogenetic kingdoms.
