Answer:
Never leave an open flame unattended
Explanation: if an open flame is left unattended it can cause a fire outbreak so we have to watch it at all times to prevent the fire outbreak
Nitrogen atomic# 7 7protons, 7electrons, 7 neutrons
Oxygen atomic# 8 8protons, 8electrons, 8neutrons
Phosphorous atomic# 15 15protons, 15 electrons, 15 neutrons
Sulfur atomic#16 16protons, 16electrons, 16 neutrons
Answer:
Option B
Explanation:
As Brønsted-Lowry theory states, acids are the ones that can donate protons.
When a proton is donated, it is released to become medium more acidic.
HCl is a strong acid.
HCl (l) + H₂O (l) → H₃O⁺ (aq) + Cl⁻(aq)
These always reffers to strong acid where the dissociation is 100% completed.
In a weak acid, dissociation is not 100% complete, that's why we have an equilibrium.
HA (l) + H₂O (l) ⇄ H₃O⁺ (aq) + A⁻(aq) Ka
