Answer: the gas molecules interact with one another
Explanation:
Answer:
When an atom gains or loses energy, the energy of an electron can change.
An electron in an atom can move from one energy level to another when the atom gains or loses energy.
Explanation:
The possible energies that electrons in an atom
can have are called energy levels.
• An electron cannot exist between energy levels.

Answer:
IO₂
Explanation:
We have been given the mass percentages of the elements that makes up the compound:
Mass percentage given are:
Iodine = 79.86%
Oxygen = 20.14%
To calculate the empirical formula which is the simplest formula of the compound, we follow these steps:
> Express the mass percentages as the mass of the elements of the compound.
> Find the number of moles by dividing through by the atomic masses
> Divide by the smallest and either approximate to nearest whole number or multiply through by a factor.
> The ratio is the empirical formula of the compound.
Solution:
I O
% of elements 79.86 20.14
Mass (in g) 79.86 20.14
Moles(divide by
Atomic mass) 79.86/127 20.14/16
Moles 0.634 1.259
Dividing by
Smallest 0.634/0.634 1.259/0.634
1 2
The empirical formula is IO₂
Answer:
The polar nature of water splits the acid molecules into its cations and anions. Cations and anions are charged particles and are free to move inside the aqueous medium. As a result when a potential difference has applied the solution to conduct electricity.

Answer:
<h3><em>A is most likely your correct answer</em></h3>
Explanation:
A. Hills Covered with dry brush- this is most likely correct
b. Hills covered in lush grass- incorrect, because it is LUSH grass which would require lots of rain.
c. Flat lands with little grass- incorrect because grasslands DO have lots of grass.
D- incorrect because grasslands typically do NOT have rocky mountains <u>but are generally flatlands with grass</u>
