Answer:
the bread rising shows that it’s baking which is a chemical reaction
Explanation:
Answer:
Volume will decreased by decreasing the amount of gas.
Explanation:
The amount of gas and volume are directly related to each other. By decreasing the amount of gas volume will decrease by keeping the temperature and pressure constant.
Mathematical expression:
V ∝ n
V = Kn
we put the K by removing the sign of proportionality.
K = proportionality constant
n = amount of gas
V = volume of gas
The volume- amount relation is called Avogadro law.
By increasing the amount of gas volume will also goes to increase.
This is an example of sphere interaction of the biosphere, hydrosphere, and lithosphere.
Answer:
Option A. 1191.49 K
Explanation:
Data obtained from the question include:
The equation for the reaction is given below:
4HCl + O2 —> 2Cl2 + 2H2O
Enthalpy (H) = +280 KJ/mol = +280000 J/mol
Entropy (S) = +235 J/Kmol
Temperature (T) =..?
The temperature at which the reaction will be feasible can be obtained as follow:
Change in entropy (ΔS) = change in enthalphy (ΔH)/T
(ΔS) = (ΔH)/T
235 = 280000/T
Cross multiply
235 x T = 280000
Divide both side by 235
T = 280000/235
T = 1191.49 K
Therefore, the temperature at which the reaction will be feasible is 1191.49 K
