Answer:
the rock has a greater amount of heat energy which transfers to water causing vaporization.
Answer:
93.5 moles N₂
Explanation:
To find the moles, you need to use the Ideal Gas Law. The equation looks like this:
PV = nRT
In this equation,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = number of moles
-----> R = constant (0.0821 atm*L/mol*K)
-----> T = temperature (K)
You can plug the given values into the equation and simplify to find moles. The final answer should have 3 sig figs to match the lowest number of sig figs among the given values.
P = 95.0 atm R = 0.0821 atm*L/mol*K
V = 224 L T = 2773 K
n = ?
PV = nRT
(95.0 atm)(224 L) = n(0.0821 atm*L/mol*K)(2773 K)
21280 = n(227.6633)
93.5 = n
<h3>
Answer:</h3>
B Aqueous
<h3>
Explanation:</h3>
We are given the equation;
KBr (aq) + AgNO₃ (aq) → KNO₃ (aq) + AgBr (s)
- The equation shows a precipitation reaction or a double displacement reaction.
- Precipitation reaction because two soluble salts reacts to produce a precipitate as one of the product.
- Double displacement reaction because the salts exchange cations and anions to form new compounds
- In the equation;
- KBr is in aqueous state since all salts of potassium (K) are soluble in water.
- KNO₃ and AgNO₃ are also in aqueous state as all nitrates are soluble in water.
- AgBr on the other hand is in solid state since its a precipitate that is insoluble in water.
Answer:
liquid junction potentials
when a cell contains a boundary between two electrolytic solutions of different composition or concentration, a liquid junction potential is developed due to the "diffusion of the various components at characteristic rates in the boundary zone."
