Answer:
A tropical storm at sea has been upgraded to a hurricane.
Explanation:
Hurricane warnings are issued with respect to the conditions that may cause the commencement of a hurricane in a particular area. The warning is issued before the winds hit the tropical storm force. This helps in preparing for all the necessary precautionary steps before the storm force effects. The humans are strictly orders to evacuate the area immediately.

1. 16 mL
2. She need to find the mass, as density is mass divided by volume.
3. 0.75 g/cm^3
NH₃, being a basic gas neutralizes the HNO₃ forming a salt NH₄NO₃
Therefore the correct answer is NH₃ and NH₄NO₃
The solution of which only 32% dissociates to release OH⁻ ions is a weak base. This is because some of the energy is used when the substance reacts with the solution thus some bonds are not broken.
HCl is an acid. This is because it dissociates in water to give H⁺ as the only positively charged ions.
Arrhenius acid increases the concentration of hydrogen ions because it dissociates to release hydrogen ions as the only positively charged ions in the acid. So the answer is TRUE
Arrhenius base dissociates in water to release hydroxide ions as the only negatively charged ions.
NaOH⁺aq⇒Na⁺ ₍aq₎+ OH⁻₍aq₎
