Answer: I think the answer is C. NaCl and H2O
Explanation: I’m not sure tho
This problem is providing us with the mass of propane, its enthalpy of combustion, and the initial and final temperature of water that can be heated from the burning of this fuel. At the end, the result turns out to be 42.27 L.
<h3>Combustion:</h3>
In chemistry, combustion reactions are based on the burning of fuels by using oxygen and producing both carbon dioxide and water. For propane, we will have:

Hence, we can calculate the heat released from this reaction by using the mass, which has to be converted to moles, and the given enthalpy of combustion:

<h3>Calorimetry:</h3>
In chemistry, we can analyze the mass-specific heat-temperature-heat relationship via the most general heat equation:

Thus, since Q was obtained from the previous problem, but the sign change because the released heat is now absorbed by the water, one can calculate the mass of water that rises from 20.0°C to 100.0°C with this heat:

Finally, we convert it to liters as required:

Erosols aren't aerosols at all. No, really, let's be clear about this. An aerosol is really the cloud<span> of </span>liquid and gas<span>that comes out of an aerosol can, not the can itself. In fact, to be strictly correct about it, an aerosol is a fine mist of liquid, or lots of solid particles, widely and evenly dispersed throughout a gas. So clouds, fog, and steam from your kettle are all examples of aerosols, because they're made up of </span>water<span> droplets dispersed through a much bigger volume of air. Smoke is an aerosol too, though unlike those other examples (which are liquids dispersed in gases) it's made up of </span>solid<span> particles of unburned carbon mixed through a cloud of warm, rising air. Even </span>candles<span> make aerosols: the smoky steam swirling above a candle flame consists of soot and water vapor dispersed through hot air.

The mole is simply an Avogadros number of anything( in this case Br atoms)
The Avogadro number is 6.022 x 10^23.
So no of moles = No of atoms / 6.022 x 10^23 = 2.03 x 10^24 / 6.022 x 10^23 = 3.37 Moles.
Answer:
Cu₃(PO₄)₂(s), RbNO₃(aq)
Explanation:
This reaction looks like a possible <em>double replacement reaction</em>, in which the metal ions have exchanged partners.
3Cu(NO₃)₂(aq) + 2Rb₃PO₄(aq) ⟶ Cu₃(PO₄)₂ + 6RbNO₃
You must recall the pertinent <em>solubility rules</em>:
1. Salts of Group 1 elements (e.g., Rb⁺) are soluble.
2. Salts containing nitrate ions (NO₃⁻) are soluble.
3. Most salts containing phosphate ions (PO₄³⁻) are insoluble
According to Rules 1 and 1, RbNO₃ is soluble.
According to Rule 3, Cu₃(PO₄)₂ is insoluble.
∴ 3Cu(NO₃)₂(aq) + 2Rb₃PO₄(aq) ⟶ Cu₃(PO₄)₂(s) + 6RbNO₃(aq)
