Any reaction between americium and helium.
the balanced equation is Na2S2O3 plus H2O2 yields 2NaOH plus H2S2O3 plus O2.
This substance is a base.
When two helium atoms combine, they form a molecule of helium gas (He2), which is also known as a dihelium molecule. This molecule is quite rare and unstable under normal conditions, as helium typically exists as a monoatomic gas.
Helium atom is neutral and has no charge. It becomes a positive ion with a charge of +1 when it loses an electron.
A substance that yields an anion plus the hydroxyl ion in water is a strong base. Examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH) which dissociate completely in water to produce hydroxide ions.
Silver nitrate plus potassium iodide yields silver iodide plus potassium nitrate.
H2co3
the balanced equation is Na2S2O3 plus H2O2 yields 2NaOH plus H2S2O3 plus O2.
2NaH2 + O2 yields 2Na + 2H2O
its balanced
C3h8 + 5o2 --> 3co2 + 4h2o
No its a combustion reaction, not a double replacement
NO. There is no chlorine on the reactant side, so it cannot be balanced.
The Answer:Adding the 2 numbers yields: 1424374656676.
