Answer:
The given parameter for the solubility of NaNO₃ in H₂O are;
The maximum solubility of NaNO₃ in H₂O at 10°C = 78 g
1. If we have 50 g of NaNO₃ in 100 g of water at 10°C, the solution is;
Undersaturated
2. If we have exactly 78 g of NaNO₃ in 100 g of water at 10°C the solution is;
A saturated solution
3. If will add 80 g of NaNO₃ in 100 g of water at 10°C,
The excess NaNO₃ which cannot be dissolved will be observed as solids in the mixture
4) The quantity of NaNO₃ that can be dissolved in H₂O at 40°C = 94 g
If the solution containing 94 g of NaNO₃ at 40°C is cooled to 10C about 16 g of NaNO₃ will precipitate out of the solution and exist as solids in the mixture
Explanation:
1. An undersaturated is a solution that holds smaller amount of solute that it can hold at a given temperature
2. A saturated solution holds as much solute as it can dissolve at a given temperature
3. When more solutes are added to a saturated solution, the excess solution will remain in the solid form in the mixture
4) Cooling a saturated solution below the saturation temperature will result in the precipitation or crystallization of the excess solutes in the solution.
Answer:
The chemistry formulas are formed by the chemical reactions of chemical substances.
Explanation:
The chemical substances are introduced together to find the chemical reactions and then equations are formed. The equations them used to form the formulas for the chemical reactions that are performed. The quantity of the acid and base need to be carefully introduced when performing a titration process.
Answer: The equilibrium concentration of 
will be much smaller than the equilibrium concentration of 
, because Keq<<1
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as 
K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
For the given chemical reaction:
The expression for is written as:
![K=\frac{[H_3O^+]\times [BrO^-]}{[HBrO]}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BH_3O%5E%2B%5D%5Ctimes%20%5BBrO%5E-%5D%7D%7B%5BHBrO%5D%7D)
Concentration of pure solids and liquids is taken as 1.
Thus as 
, That means the concentration of products is less as the reaction does not proceed much towards the forward direction.
Answer:
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
Explanation:
Mid-ocean ridges and seafloor spreading can also influence sea levels. As oceanic crust moves away from the shallow mid-ocean ridges, it cools and sinks as it becomes more dense. ... Seafloor spreading proves that the ocean itself is a site of tectonic activity.
for one you could do a bell, ringing noise, then say someone rang it.
For two you could do tunnel, echoing, then say someone yelled and it echoed.
for three you could do a bowl, ringing, spoon hitting it
hope i could help
