Answer:
3.4752 moles of water
Explanation:
There are 13.84 mole in one cup of water so,
13.84 divided by 4= 3.4725 :)
The rate of dissolution of a solid solute into the solution decreases when you stop stirring it. Generally, stirring increases the dissolution rate of a solid into a solution. An example is coffee with sugar, the sugar dissolves faster when stirred versus when left to dissolve on its own.
Answer:
0.0702J/g°C the specific heat capacity of the metal.
Explanation:m
![Q=m\times c\times \Delta T=m\times c\times (T_{2}-T_{1})](https://tex.z-dn.net/?f=Q%3Dm%5Ctimes%20c%5Ctimes%20%5CDelta%20T%3Dm%5Ctimes%20c%5Ctimes%20%28T_%7B2%7D-T_%7B1%7D%29)
where,
Q = heat absorbed by metal = 186.75 J
= Mass of metal= 19 g
= Initial temperature of metal = ![35^oC](https://tex.z-dn.net/?f=35%5EoC)
=Final temperature of metal = ![175^oC](https://tex.z-dn.net/?f=175%5EoC)
= specific heat of metal= ?
![186.75 J=19 g\times c\times (175^oC-35^oC)](https://tex.z-dn.net/?f=186.75%20J%3D19%20g%5Ctimes%20c%5Ctimes%20%28175%5EoC-35%5EoC%29)
![c=\frac{186.75 J}{19 g\times (175^oC-35^oC)}](https://tex.z-dn.net/?f=c%3D%5Cfrac%7B186.75%20J%7D%7B19%20g%5Ctimes%20%28175%5EoC-35%5EoC%29%7D)
![c=0.0702J/g^oC](https://tex.z-dn.net/?f=c%3D0.0702J%2Fg%5EoC)
0.0702J/g°C the specific heat capacity of the metal.
Answer:
B. Below the equilibrium price
Explanation:Price ceiling is the legal price,impose by The Government or Regulatory agencies above which a product should not be sold. It is also a price control mechanism through which the Government and other Regulatory agencies check the excesses of producers and the middle men(Whole sellers and retailers). The price ceiling has to be fixed below the equilibrium price for it to be binding, because businesses are interested mainly for profit maximization.
