Answer:
Answer a) is 2000 mL solution 1.
Answer b) is 40 mL solution 1 and 60 mL solution 2.
Answer c) isn't possible to produce a solution with 90% benzene and 10% toluene because is a percentage of benzene higher than the solution 1 and solution 2.
Explanation:
You can solve using an equation system base on the benzene percentage/ratio of each solution.
Answer a) X-> mL of solution 1
x*0.8+500*0.3=(500+ x)*0.7
x *0.8+500*0.3=500*0.7+ x*0.7
x*(0.8-0.7)=500*(0.7-0.3)
X*0.1=200
x=2000mL
Answer b) X-> mL of solution 1
x*0.8+(100-x)*0.3=(100)*0.5
x *0.8+100*0.3-x*0.3=50
x*(0.8-0.3)=50-30
x*(0.5)=20
x=40 mL
mL of solution 2=(100-x)=100-40=60 mL
The balanced net iconic equation :
- (a) 2HNO3 (aq) Ba(OH)2 (aq) Ba(NO3) (aq) + 2H20
- (b) HF(aq) + K+(aq) + OH-(aq) → K+(aq) + F-(aq) + H2O(l) Net: HF(aq) + OH-(aq) → H2O(l) + F-(aq)
- (c) C6H5NH2 + HClO4 → ClC6N + 4H2O
<h3>Briefing :</h3>
Salt and water are created when an acid and a base interact then Acid-based reaction happens. Because both water and salt are neutral, if an acid and a base react together, they cancel out each other's effects. It is referred to as a neutralization reaction as a result.
<h3>What is acid-base reaction?</h3>
An acid-base reaction is a chemical reaction involving an acid and a base.
H+ and OH- ions are produced by bases and acids, respectively, and these ions combine to make water. There are a number of drawbacks to the Arrhenius theory. Because it defines acids and bases in terms of what occurs when compounds dissolve in water, it can only be applied to reactions that take place there.
One or more hydrogen ions, H+, are exchanged between entities that may be neutral (such as H2O) or electrically charged (ions-ammonium, NH4+; hydroxide, OH; or carbonate, CO32); in an acid-base process.

An element is the simplest form of matter that has a unique set of properties. Elements cannot be broken down into a simpler substance. Likewise, one element cannot be chemically converted into a different element.

Molecular geometry about the left carbon atom in CH₃CO₂CH₃ is tetrahedral.
The geometry around left carbon that is CH₃ is tetrahedral.
As the hybridization around left carbon is sp³ that shows its geometry should be tetrahedral and as there are 4 ligands around carbon and there is no lone pair present so the geometry is tetrahedral. So, the molecular geometry about the left carbon atom in CH₃CO₂CH₃ is tetrahedral.
