Tell me the facts about life just kidding tell me do worms have mouths

Carbon dioxide dissolves out of the blood back to the skin. Eating: Worms do not have teeth, but their mouths are muscular and strong. Night crawlers can even pull leaves into their burrows using their strong mouths. ... The worm's stomach is very muscular, so is called a gizzard.

Explanation:

i used google

Yes they do in the back ig Worms do not have teeth, but their mouths are muscular and strong.

Explanation:

Thta's kinda wired tho

  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

it has to be b, about 97 percent.
