Combustion reaction because it produces water and carbon dioxide
Answer:
The volume will not change. This belongs in Ripley's Believe It or Not.
Explanation:
The combined gas law can be used to model both the initial (1) and ending (2) states of a gas when pressure (P), temperature (T) and/or volume (V) change, but the number of moles does not. Remember that temperature must always be in Kelvin.
P1V1/T1 = P2T2/T2
Rearranging for V2:
V2 = V1(T2/T1)(P1/P2)
I've arranged the pressure and temperature terms as ratios. This makes it easier to see what impact changes will have, plus the units conveniently cancel for both.
(V2) = (1 L)(T2/T1)(P1/P2)
We are told that P2 and T2 are both doubled:
(T2/T1) = 2
(P1/P2) = 1/2
V2 = (1 L)(T2/T1)(P1/P2)
V2 = (1 L)(2)(1/2)
V2 = (1 L)(2)(1/2)
V2 - 1 L
The volume does not change. Bummer.
Answer:
NH₄⁺ (aq) + OH⁻ (aq)+ H⁺ (aq)+ Cl⁻ (aq) → NH₄⁺ (aq)+ Cl⁻ (aq)+ H₂O (l)
Explanation:
NH₄OH (l) + HCl (l) → NH₄Cl (aq) + H₂O (l)
This is called a <u>molecular equation</u> because <em>the formulas of the compounds are written as though all species existed as molecules or whole units</em>.
However, because both the acid and the base are strong electrolytes, they are completely ionized in solution. Therefore, the ionic equation is:
NH₄⁺ (aq) + OH⁻ (aq)+ H⁺ (aq)+ Cl⁻ (aq) → NH₄⁺ (aq)+ Cl⁻ (aq)+ H₂O (l)
B, it's properly because of convection! Please, correct me if I'm wrong :>
