Answer:
Bari oxit được tạo nên từ các nguyên tố Bari (Ba) và Oxi (O)
Explanation:
Answer:
Enzymes.
Explanation:
That would be enzymes. They increase the rate of chemical reactions in cells.
As long as there is some oxygen, the reaction will occur. If there is an insufficient amount of oxygen, then the oxygen will be the limiting reacting and there will be excess of the other reactants.
It has a single valence electron.
3pro & 3ele - it is the single electron in shell 2.
The balanced chemical reaction would be:
KHC8H4O4<span> (aq) + </span>NaOH<span> (aq) → NaKC8H4O4 (aq) + H2O.
The concentration of the NaOH is equal 0.1 M. We use this and the volume given above to determine the mass of KH</span>C8H4O4. We do as follows:
0.1 mol / L NaOH (.015 L) ( 1 mol KHC8H4O4 / 1 mol NaOH) (204 g / 1 mol) = 0.306 g KHC8H4O4
