2. 
3. 
Explanation:
Hello there!
2. In this case, we can evidence the problem by which volume and temperature are involved, so the Charles' law is applied to:
Thus, considering the temperatures in kelvins and solving for the final volume, V2, we obtain:
Therefore, we plug in the given data to obtain:
3. In this case, it is possible to realize that the 3.7 moles of neon gas are at 273 K and 1 atm according to the STP conditions; in such a way, considering the ideal gas law (PV=nRT), we can solve for the volume as shown below:
Therefore, we plug in the data to obtain:
Best regards!
12, if the decimal is over five, round up. If it's not, round down. Not sure what you mean by significant figures.
Answer:
Weathering is the breaking down of rocks, soil, and minerals as well .
Explanation:
in the same place, with little or no movement, and thus should not be confused with erosion, which involves the movement of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity and then being transported and deposited in other locations.
1mile/13min * 1min/60sec * 63360in/1mil = 63360in/780sec = 81.23 in/sec
A. Strontium Phosphate
Solubility product constant is an equilibrium constant for the maximum amount of solute that can dissolve to form an aqueous solution. The value of the constant describes a solution which is saturated.
The greater the solubility product constant, the more soluble a solute is in the liquid. Consequently, the smaller the constant, the less soluble the solute is. The following list shows the solubility product constants of the given compounds in aqueous solutions at 298K in decreasing order:
Thallium Bromide - 3.71×10–6
Copper Iodide - 1.27×10<span>–12
</span>Silver Bromide - 5.35×10–13
Silver Arsenate - 1.03×10–22
Mercury Bromide - 6.40×10–23
Strontium Phosphate - 1×10–31
<span>
The salt with the smallest solubility product constant is strontium phosphate, and therefore is the one which is least soluble in water.
