Answer:
acid +alkaline =salt and water
Explanation:
if an acid reacts with an alkaline they form salt and water
Answer:
1) Increasing temperature
2) Stirring
3) Increasing surface area of salt by grinding it
I will say this is True….?
Explanation:
Since mole ratio of O2 : NH3 = 7 : 4,
Volume of NH3 = 50dm³ * 4/7 = 28.57dm³.
The complete question is shown in the image attached to this answer.
Answer:
C
Explanation:
Let us quickly remember that the EMF of a cell under non standard conditions in given by the Nernst equation.
This equation states that;
E = E°cell - 0.592/n log Q
Where
E = EMF under non standard conditions
E°cell= standard EMF of the cell
n = number of electrons transferred
Q = reaction quotient
If the reaction quotient is greater than 1 then cell potential is less than the standard cell potential.
The cell that generates the lowest cell potential is the cell depicted in option C because Q has the greatest positive value(Q<1).
