Predict whether each of the following reactions will occur in aqueous solutions. Explain your reasoning in each case. Note: Bari
tino4ka555 [31]
(a) sodium hydroxide + ammonium sulfate --> sodium sulfate + ammonium hydroxide

sodium sulfate precipitates in aqueous solutions

(b)<span> niobium(V) sulfate + barium nitrate →  Barium sulfate + niobium nitride

both do not precipitate in aqueous solution

</span>(c) strontium bromide + silver nitrate ---> strontium nitrate + silver bromide

both  do not precipitate in aqueous solution

The volume of a gas is 1.15 L at STP. At what temperature would the volume of the gas increase to 1.56 L, if the pressure is dec
denis23 [38]

A gas occupies 1.15 L at standard pressure and temperature and 1.56 L at 317 K and 650 mmHg, assuming ideal behavior.

<h3>What is an ideal gas?</h3>

An ideal gas is a gas whose behavior can be explained through ideal gas laws. One of them is the combined gas law.

A gas occupies 1.15 L (V₁) at STP (T₁ = 273,15 K and P₁ = 760 mmHg). We can calculate the temperature (T₂) at which V₂ = 1.56 L and P₂ = 650 mmHg, using the combined gas law.

\frac{P_1 \times V_1}{T_1} = \frac{P_2 \times V_2}{T_2}\\T_2 = \frac{P_2 \times V_2 \times T_1}{P_1 \times V_1} = \frac{650mmHg \times 1.56 L \times 273.15K}{760mmHg \times 1.15 L} = 317 K

A gas occupies 1.15 L at standard pressure and temperature and 1.56 L at 317 K and 650 mmHg, assuming ideal behavior.
