Pressure does not affect the voltage produced in a voltaic cell.
Explanation:
Gases: more space therefore meaning that particles in the gas have the highest Kinetic energy therefore moving faster all around.
Liquid: they have more kinetic energy than liquid,but they have some space for movement so they collide each other quicker due to lack of space.
solids: They have least kinetic energy as they have no space at all meaning particles can move around and only just vibrate against each other.
A) Combustion

Explanation:
Given :
Amount of solute - sucrose (C12H22O11) = 41 g
Amount of solvent -soda = 355-mL
Molarity of the solution with respect to sucrose= ?
Molarity(M) is a unit of concentration measuring the number of moles of a solute per liter of solution. The SI unit of molarity is mol/L.
Formula to find the molarity of solution :
Molarity =
Amount of solvent is given in mL, let’s convert to L :
1 L = 1000 mL
Therefore, 355 mL in L will be :
= 0.355 L
We have the amount of solute in g, let’s calculate the number of moles first :
Number of moles (n) =
Molar mass of C12H22O11 = 342.29 g/mol.
Therefore, n =
= 0.119 moles.
Answer: the difference in their electronegativities
