C6H12O3 is a molecular formula that contains 54.5% C, 9.1% H, and 36.4% O and <span>has a molar mass 132 amu. </span>
Answer:
The "word equation" is Magnesium + Dioxygen → Magnesium Oxide
Explanation: This is also the same as Mg + O₂ → MgO.
Answer:
The protons and electrons in each element are equal. The sulfur has 16 electrons and 16 protons. But the ionic atom's electron quantity changes depending on how many it has gained. 'S2-' has gained 2 electrons, which means it has now 18 electrons and 16 protons. 16 neutrons
Explanation:
The HCl is a strong acid, that is, it is fully consumed <span>in the reaction.
HCl(aq) ------------> H</span>₃O⁺(aq) + Cl⁻(aq)
↓ ↓ ↓
10⁻⁴ M 0 0
-10⁻⁴ +10⁻⁴ +10⁻⁴
_____________________________________
0 + 10⁻⁴ M <span> + 10⁻⁴ M
PH = - log [ H</span>₃O⁺ ]
PH = - log [ <span>10⁻⁴]
<span>PH = 4.0</span></span>
