Answer: The number of collisions increase
Explanation: When temperature increases, that means the molecules move faster having a higher average kinetic energy. Therefore, the number of collisions increase.
<u>Answer:</u> The mass of water that should be added in 203.07 grams
<u>Explanation:</u>
To calculate the molality of solution, we use the equation:
![\text{Molality}=\frac{m_{solute}\times 1000}{M_{solute}\times W_{solvent}\text{ (in grams)}}](https://tex.z-dn.net/?f=%5Ctext%7BMolality%7D%3D%5Cfrac%7Bm_%7Bsolute%7D%5Ctimes%201000%7D%7BM_%7Bsolute%7D%5Ctimes%20W_%7Bsolvent%7D%5Ctext%7B%20%28in%20grams%29%7D%7D)
Where,
m = molality of barium iodide solution = 0.175 m
= Given mass of solute (barium iodide) = 13.9 g
= Molar mass of solute (barium iodide) = 391.14 g/mol
= Mass of solvent (water) = ? g
Putting values in above equation, we get:
![0.175=\frac{13.9\times 1000}{391.14\times W_{solvent}}\\\\W_{solvent}=\frac{13.9\times 1000}{391.14\times 0.175}=203.07g](https://tex.z-dn.net/?f=0.175%3D%5Cfrac%7B13.9%5Ctimes%201000%7D%7B391.14%5Ctimes%20W_%7Bsolvent%7D%7D%5C%5C%5C%5CW_%7Bsolvent%7D%3D%5Cfrac%7B13.9%5Ctimes%201000%7D%7B391.14%5Ctimes%200.175%7D%3D203.07g)
Hence, the mass of water that should be added in 203.07 grams

Explanation:
Answer:
![\mathbf{AgNO_3+Cl^- \to AgCl_s + NO^{3-}}](https://tex.z-dn.net/?f=%5Cmathbf%7BAgNO_3%2BCl%5E-%20%5Cto%20%20AgCl_s%20%2B%20NO%5E%7B3-%7D%7D)
Explanation:
The addition of AgNO3 to the system Cl⁻ react with result into the formation a precipitate of AgNO3, as such the reactant concentration decreases.
![\mathbf{AgNO_3+Cl^- \to AgCl_s + NO^{3-}}](https://tex.z-dn.net/?f=%5Cmathbf%7BAgNO_3%2BCl%5E-%20%5Cto%20%20AgCl_s%20%2B%20NO%5E%7B3-%7D%7D)
Suppose the concentration of a given substance is present in an equilibrium system is changed without a change in any of the other conditions, then, by le chatelier's principle, the position of equilibrium will move to decrease the concentration of the added substances. In order to relieve this constraint, the equilibrium will shift to the right favouring the forward reaction.
Heptane has nine structural isomers are 2-methylhexane, 3-methylhexane, 2,2-dimethylpentane, 2,3-dimethylpentane, 2,4-dimethylpentane, 3,3-dimethylpentane, 3-ethylpentane and 2,2,3-trimethylbutane. Each compound must have the same molecular formula but the structure of each are different from each other.
