Help please, thank you:)

Chemistry
1 answer:
IgorC [24]3 years ago
6 0

Answer:

1.67 × 10⁻¹⁰m is the answer.

Explanation:

Given,

4 × 10⁻⁷m thick

2400 atoms thick

therefore 1 atom,

Diameter = 4 × 10⁻⁷/2400

d = 4000 × 10⁻¹⁰/2400

d = 1.67 × 10⁻¹⁰m

∴ diameter of 1 gold atom (3 significant figures) = 1.67 × 10⁻¹⁰m

How can you tell which ionic compounds will react in an aqueous solution
Darina [25.2K]
1.  Determine if the ionic substances can break apart into ions.
 - e.g. CaCO3 isn't very soluble, do it can't dissolve and dissociate.  If it can't pop apart, no ions.
2.  Swap the partners for all the other ions that you can get from step 1.  You can skip pairings with the same charge - a + can't get close to another + to react.
3.  Use solubility, acid/base, and redox rules to see if anything will happen with the ions in solution.<span />

From the list below, determine which properties are for compounds. I. It takes a large amount of energy to separates the element
marshall27 [118]
All of them are properties of compounds except III.

for I, compounds are chemically combined together, so to separate them, we must use chemical methods like electrolysis or applying heat. These requires large amount of energy.

For II, they're always fixed. For example, in water (H2O), the ratio of hydrogen and oxygen is always 1:8 in mass. If there's some extra added, the substance becomes mixture instead of compounds.

For IV, after you chemically combined elements or compounds together, their properties are completely different. For example, iron can be attracted to magnets, but iron II sulphide does not.
