Answer : The molality of the solution is, 0.788 mole/Kg
Solution : Given,
Mass of solute, 
= 25 g
Mass of solvent, 
= 125 g
Molar mass of solute, = 253.8 g/mole
Molality : It is defined as the number of moles of solute present in one kilogram of solvent.
Formula used :
Now put all the given values in this formula, we get the molality of the solution.
Therefore, the molality of the solution is, 0.788 mole/Kg
Answer:
Grass, deer, wolf, fungi.
Explanation:
The tropical level of an organism is defined as the position of organism occupied in the food chain. The food chain is starts from tropical level one which is primary producers (such as plants), then move to herbivores (such as deer) in level two, carnivores, (such as wolf) at level three, apex predators in level four (such as lions), and it ends in decomposers such as fungi.
Fungi play important role in ecosystem to help in breakdown of dead organic matter and return nutrients to the soil. Without fungi nutrients cannot cycle in an ecosystem, and causing the breakdown of entire food web.
The following equilibrium will shift in the direction of the product:
<h3>Further explanation</h3>
Given
Reaction
4HCl + O₂ → 2H₂O + 2Cl₂
Cl₂ was removed
Required
Equilibrium changes
Solution
Reaction = - action
adding the products ⇒ Shifts in the direction of the reactants
reducing the products ⇒Shifts in the direction of the products
Cl₂ as a product, so if Cl₂ is taken or reduced, the reaction will try to maintain system equilibrium by moving to the right (product formation) ⇒ Shift in the direction of the product:
Mass is how much matter is in an object. Volume is how much space an object occupies. Density is the amount of mass in a volume.
