Answer:
Disagree.
Explanation:
Nothing would remain. Everything on Earth is made up of atoms. The chair consists of only atoms. So, if you remove all of the atoms, nothing would be left! Hope this helps.
I believe that the molar mass is 342.34g/mol
It will belong to the metals because metals bond with nonmetals like chlorine to form ionic compounds
The
reaction is<span>
C</span>₂H₄ +
O₂ → CO₂ + H₂O<span>
To balance the equation, both side have same
number of elements. Here,</span>
In left hand
side has
in right hand side has
4 H atoms
2 H
atoms
2 C atoms 1 C
atom
<span>
2 O atoms 3 O
atoms
First, we have to balance number of C atoms and number of H atoms in both side.
To balance C atoms, '2' should be added before CO</span>₂ and to balance H atoms, '2' should be added
before H₂<span>O.
Then number of oxygen atoms is </span>2 x 2 + 2 = 6 in right hand side. So, 3 should be
added before O₂<span> in left hand side.
After balancing the equation should be,</span>
C₂H₄<span> + 3O</span>₂<span> → 2CO</span>₂<span> + 2H</span>₂O
NaHCO3 is the right answer
