Answer:
179.4306 g
Explanation:
Given that:
Mass of
= 198 g
Molar mass of
= 465.96 g/mol
The formula for the calculation of moles is shown below:
Thus,

From the balanced reaction,

1 mole of
on reaction produces 2 moles of bismuth
So,
0.4293 mole of
on reaction produces 2 × 0.4293 moles of bismuth
Moles of bismuth = 0.8586 moles
Molar mass of bismuth = 208.9804 g/mol
<u>So, mass of bismuth = Moles × Molar mass = 0.8586 × 208.9804 g = 179.4306 g</u>
Answer : The concentration in (M)of bromide ions in a saturated solution of mercury (II) bromide is, 
Explanation :
The solubility equilibrium reaction will be:

Let the molar solubility be 's'.
The expression for solubility constant for this reaction will be,
![K_{sp}=[Hg^{2+}][Br^{-}]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BHg%5E%7B2%2B%7D%5D%5BBr%5E%7B-%7D%5D%5E2)


Given:
= 
Now put all the given values in the above expression, we get:



Therefore, the concentration in (M)of bromide ions in a saturated solution of mercury (II) bromide is,

Answer:
A three-carbon chain has a straight line extending from the center carbon.
Explanation:
Isomers are compounds having the same molecular formula but different structural formulas.
Butane and 2-methylpropane are constitutional isomers. Constitutional isomers differ in the way that the constituent atoms are connected to each other.
Butane is a straight chain compound while the compound 2-methylpropane consists of a three-carbon chain which has a straight line extending from the center carbon.
