Answer:
I think scientists should not clone the wooly mammoth because our environment is already working great without them and bringing them back has a chance to hurt the environment or even destroy it also wooly mammoths were exists about 3700 years ago and the world had changed A LOT from then so we could end up hurting the mammoth by putting it in a world that has changed a lot from when the wooly mammoth was actually alive.
Answer:
you can't go through a solid unless you broke the atoms in the wall
Moles H2O = 362 / 18.02 g/mol=20
<span>2 H2 + O2 = 2 H2O </span>
<span>moles H2 = 40.5 g / 2.016 g/mol=20 </span>
<span>the ratio between H2 and H2O is 2 : 2 so the yield is 100% </span>
<span>moles O2 required = 20 / 2 = 10 </span>
<span>mass O2 = 10 mol x 32 g/mol= 320 g</span>
