Answer:
The main difference is their energy level, 2s orbital is higher than 1s orbital.
Answer:
C) non renewable resources
Explanation:
These are resources such as oil that are formed over a long period of time but are consumed very quickly.
Density of a solution is mass of solution per unit volume
Density = mass/volume
mass of solution is 46.08 g
volume of solution is 58.9 mL
since mass and volume is known, density can be calculated
density = 46.08 g / 58.9 mL = 0.78 g/mL
S2O2 because the molecular formula of SO is just SO because they are both diatomic elements, but the empirical formula is just the but mot simplified, or S2O2.
A reaction in which two ions switch places is called double-displacement reaction.
Explanation:
Double displacement reaction usually takes place between two positive ions or two negative ions. When anions or cations of totally different compounds change places, two totally different compounds are formed.
<u>Syntax for double displacement reaction:
</u>
AB + CD --> AD + BC
It can also be defined in simple terms as the reaction in which exchange of ions takes place is called double displacement reaction.
The chemical reaction is as follows:
NaOH(aq) + HCl(aq) --> NaCl(aq) + H2O (l)
