Heyo, im just double checking my answer, please help Which statement does NOT correctly describe the electric force between two particles?

If they have the same sign, the force will be away from each other; if they have opposite signs, the force will be towards each other

The farther apart they are, the smaller the force will be

The greater each charge is, the more force there will be

If they are moving towards each other, the force will be perpendicular; if they are moving away from each other, the force will be parallel

Option D

Explanation:

Option A is not not correct because it correctly defines the electric force which is repulsive in case of like charges and attractive in case of opposite charges

Option B is also not correct because it is true about electric force

Option C is also not correct as electric forces are always perpendicular

Option D is incorrect as electric forces are not parallel

what was the answer?

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz
