Which of the following statements are true for magnetic field lines? Check all that apply. Check all that apply. Magnetic field lines can never intersect. Magnetic field lines point in the direction of the magnetic force acting on a charge. Magnetic field lines are close together in regions of space where the magnitude of the magnetic field is weak, and they are father apart in regions where it is strong. Unlike electric field lines, magnetic field lines are continuous. At every point in space, the magnetic field vector at that point is tangent to the magnetic field line through that point.

Magnetic field lines can never intersect.

. At every point in space, the magnetic field vector at that point is tangent to the magnetic field line through that point.

Explanation:

A magnetic field is the region surrounding a magnet where its influence is felt. The strength of a magnetic field is indicated by the intensity of magnetic field lines. These lines do not cross each other and they indicate the direction of the magnetic field. The direction of the magnetic field of a charge is given by the right hand rule. If the magnetic field at a point is strong, many lines of force are seen and vice versa.

explanation:

  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
