<span> Na2CO3 + 2HCl = CO2 + H2O + 2NaCl
this is the double displacement reaction
</span><span>2 Na(+) + CO3(-2) + 2H(+) + 2Cl(-) ------> 2Na(+) + 2 Cl(-) + H2O + CO2
</span>2Na+ and 2Cl- are the spectator ions as they appear on the both sides of equation :
so the net ionic equation can be written as :
CO3(-2) + 2H(+) -------------> <span>H2O + CO2</span>
The correct answer would be... Scientific
Based on that, alpha-particle get attracted and many of the particles were not gone away without deflection
pH = 9.5
Explanation:
We know that the hydronium ion concentration is [H₃O⁺] = 3.16 × 10⁻⁹ M.
The formula for pH is:
pH = -lg[H₃O⁺]
We input the known values to find the pH:
pH = -lg[3.16 × 10⁻⁹]
pH = 9.5
