1. Three magnets are tested by attaching paper clips to the north pole. Magnet A holds six paper clips. Magnet B holds five paper clips, and Magnet C holds two paper clips. Magnets A and C are warmed in
the oven for a few minutes and then retested. Now, Magnet A holds only four paper clips, Magnet B st
holds five paper clips, and Magnet C cannot hold any paper clips. Which statement explains the
changes?
A Warming a magnet unaligned some of the magnetic domains.
B. The forces produced by a magnet naturally become weaker over time.
C. Warming a magnet causes the distance of its magnetic force to decrease,
in change dine

the answer is false

explanation:

i believe it is b. what was the cause of the big bang

hope this !

  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
