How does the electrical force relate to the charge of an object? it is inversely proportional to the square of the charge. it is directly proportional to the square of the charge. it is inversely proportional to the charge. it is directly proportional to the charge.

It is directly proportional to the charge

Explanation:

The magnitude of the electrical force on a charge is given by:

where

q is the magnitude of the charge

E is the magnitude of the electric field acting on the charge

From the formula, we see that F (the force) is directly proportional to q /the magnitude of the charge), so the correct answer is

It is directly proportional to the charge

We can also add something about the direction of the force:

- when the charge is positive, the force has positive sign, which means that its direction is the same as the direction of the electric field (repulsive force)

- when the charge is negative, the force has negative sign, which means that its direction is opposite to the direction of the electric field (attractive force)

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂

its a 5.5 n
