Reaction:
FeCl3(aq) + 3AgNO3(aq) → Fe(NO3)3(aq) + 3AgCl(s)
Net ionic:
Ag + (aq) + Cl − (aq) → AgCl(s)
Explanation:
The evidence that a double replacement reaction has happened is the formation of a solid, liquid or gas from aqueous solutions. I’m this case case silver chloride is a precipitate.
Answer: The temperature goes up.2.The piston doesn't move in and out.3.Heat flows out.4. Amount of heat evolved is +285 kj/mol
Explanation:
The temperature in the water bath will rise because heat being evolved is absorbed it.Based on principle of constant pressure, the piston doesn't move in and out.Since the reaction is a combination reaction, heat will be evolved.
Answer:
0.16 J/g℃
Explanation:
We have the following data:
heat = 1,200 J
mass of metal = m = 150 g
change in temperature = ΔT = 50.0℃
The heat absorbed is calculated by using the following equation:
heat = m x Cp x ΔT
So, we introduce the data in the equation to calculate the specific heat of the metal (Cp), as follows:
Cp = heat/(m x ΔT) = (1,200 J)/(150 g x 50.0℃) = 0.16 J/g℃
Answer:
Temperature and Pressure
Explanation:
Temperature and pressure cause change in volume.
So any change in volume will alter the ratio of density as given by equation of density.
Density = mass/ volume
Change in volume will alter the ratio.
Kindly mark it branliest if the answer is little bit satisfying.
Answer:
Renewable
Explanation:
Reformed means it can be used multiple times, like renewable
