Answer:
Anser is C Agl
Explanation:
Agl does not dissolve in water.
Data:
Q = 402.7 J → releases → Q = - 402.7 J
m = 16.25 g
T initial = 54 ºC
adopting: c = 4.184J/g/°C
ΔT (T final - T initial) = ?
Solving:
Q = m*c*ΔT
-402.7 = 16.25*4.184*ΔT
-402.7 = 67.99*ΔT
![\Delta\:T = \frac{-402.7}{67.99}](https://tex.z-dn.net/?f=%5CDelta%5C%3AT%20%3D%20%20%5Cfrac%7B-402.7%7D%7B67.99%7D%20)
![\boxed{\Delta\:T \approx -5.92\:^0C}](https://tex.z-dn.net/?f=%5Cboxed%7B%5CDelta%5C%3AT%20%5Capprox%20-5.92%5C%3A%5E0C%7D)
If: ΔT (T final - T initial) = ?
![-5.92^0 = T_{final} - 54^0](https://tex.z-dn.net/?f=-5.92%5E0%20%3D%20%20T_%7Bfinal%7D%20-%20%2054%5E0%20)
![T_{final} = 54^0 - 5.92^0](https://tex.z-dn.net/?f=%20T_%7Bfinal%7D%20%3D%2054%5E0%20-%205.92%5E0)
The reactants and products involved in the chemical reaction are written on the left and right hand side of the equation, respectively. Thus, the reactants are SO3(g) and H2O(l). The product is H2SO4(aq). This reaction is an example of synthesis wherein two reactant combine to form one product.
AgNO3 + Cu = Cu(NO3)2 + 2Ag .. this is an example of a single replacement reaction.
Answer:
Pressure increases
Explanation:
Boyle's law states that; '' the volume of a given mass of ideal gas is inversely proportional to its pressure at constant temperature.
Hence, when the volume of a given mass of ideal gas is decreased, the molecules of the gas come closer together so they collide with each other and the walls of the container more frequently.
This implies that the pressure of the gas increases as volume decreases in accordance with Boyle's law.
