2:7 ratio of ethane to O2 = 15:x 9solve for x)
x=52.5 mol O2
Looking at this equation P= (pa*pb)/ (pa+(pb-pa)) ya where pa=vap press a and ya= vap composition a and P= total pressure,it relates vapor pressure mixture to vapor composition. This is derived using the combination of Dalton's and Raoult's laws.
Answer: Solubility
Explanation:
Solubility is the ability or property of a solute which can be a solid, liquid, or gaseous chemical substance to dissolve in a solvent (solid, liquid or gas) and form a solution. The factors that affect how soluble a substance is depends on the solvent ,temperature and pressure.
Here, Mario trying to dissolve certain substances (solutes) in water (the solvent shows he is trying to find out the solubility of the substances which can be insoluble, sparingly soluble or very soluble.
B your welcome no problem no thank you my pleasure
Answer: The coefficient we should change first is for 
.
Explanation:
The given reaction equation is as follows.
Here, number of atoms present on reactant side are as follows.
- Al = 1
- Ni = 1
- = 2
Number of atoms present on the product side are as follows.
- Al = 1
- Ni = 1
- = 3
To balance this equation, multiply Al by 2 and by 3 on reactant side. Also, multiply 
by 2 and Ni by 3 on the product side.
Hence, the equation can be rewritten as follows.
Now, number of atoms present on reactant side are as follows.
- Al = 2
- Ni = 3
- = 6
Number of atoms present on product side are as follows.
- Al = 2
- Ni = 3
- = 6
Since, the atoms on both reactant and product side are same. Hence, it is now a balanced chemical equation.
Thus, we can conclude that the coefficient we should change first is for .
