Answer:
2
Explanation:
There are some basic laws that guide the combination of elements chemically. These are the law of conservation of mass, law of definite proportion, law of multiple proportion and the law of reciprocal proportion.
For this question, the useful law to use is the law of definite proportion. Here, it is stated that no matter the method of preparation or source of preparation, the elements of a chemical compound are always present in a fixed ratio.
What this means that at any point in time, the compound titanium dioxide contains one atom of titanium and two atoms of oxygen. This means that both atoms are present at all times in a proportion of 1 to 2 .
<span>mass SO2 = 4.5 x 10^23 molecules x (1 mole / 6.023 x10^23 molecules) x (64 g/mol)
mass SO2 = 48 grams ==== answer </span>
Gasses are easy to compress
And they expand to fill their containers
Combustion is the term used when something ignites
Neutralization is the term used when opposite pH acids and alkalis mix
Polymerization is the term used when monomers are chemically reacted to make polymers
Transmutation is the term used when an atom changes from one element to another
Answer : The value of 
of the generic salt is, 
Explanation :
As we are given that, a solubility of salt is, 8.70 g/L that means 8.70 grams of salt present in 1 L of solution.
First we have to calculate the moles of salt 
Molar mass of 
= 345 g/mol
Now we have to calculate the concentration of 
The equilibrium chemical reaction will be:
Concentration of 
= 
Concentration of 
=
The solubility constant expression for this reaction is:
![K_{sp}=[A^{2+}][B^-]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BA%5E%7B2%2B%7D%5D%5BB%5E-%5D%5E2)
Now put all the given values in this expression, we get:
Thus, the value of of the generic salt is,
