1) increase in temperature (heat up). Since the reaction is exothermic because the ΔH value is negative, it means the heat is on the right side of the reaction, in the products; if there is an increase in temperature, the reaction shift away from the heat; to the left.
2) adding any of the product to the reaction, AB or C2 will cause the reaction to shift to the left because if we increase the concentrations of any, the reaction will try to decrease them by shifting away from them and use them as reactants.
3) you could increase the pressure. when pressure increases, the reaction shift to the side with less pressure, or fewer gas moles. this reaction has zero gas moles in the left but 1 in the right. so it shifts left. One way to increase the pressure is to decrease the volume of the container.
Answer:
1.99V
Explanation:
Balanced redox reaction equation:
3CU2+(aq) + 2Al(s) ------> 3Cu(s) + 2Al3+(aq)
E°cell= E°cathode- E°anode
E°cell= 0.34-(-1.66)
E°cell= 2.0V
From Nernst equation:
E= E°cell - 0.0592/n logQ
E= 2.0 - 0.0592/6 log [3.43]/[1.63]
E= 2.0- 0.0032
E= 1.99V
Heterogeneous mixtures are not similar throughout. Milk, the cake mix and smoothie are homogeneous mixtures because they have a uniform consistency throughout.
The only answer in this is D) mixed nuts.
Hope this helps! :)
Answer:
A. NaHCO₃
Explanation:
NaHCO₃ ⇒ NaOH + H₂CO₃
NaOH is a strong base and H₂CO₃ is a weak acid. Therefore, NaHCO₃ is a salt of a strong base-weak acid reaction. The salt is basic because carbonic acid (H₂CO₃) is a weak acid so it remains undissociated. So, there is a presence of additional OH⁻ ions that makes the solution basic.
Hope that helps.
