Ice cream will have a physical change because you can re freeze it and it will still be ice cream
Answer:
A. increase
Explanation:
the smaller the size of the ionic compounds, the more closer they get packed together. This means electrostatic attraction also increases, which means the ionic bonds gets stronger...therefore increases the melting point
D=m/V
1.027g/mL=m/15.0L
1.027g/mL(1000mL/L)=1027g/L=m/15.0L
m=1027g/L15.0L
m=15405g
Answer:
Her numbers are WAY too high. According to the section at the bottom, recycling cans, paper, plastics, etc. is the equivalent of taking 117 cars off of the road. If you took 117 cars off the road for a year, you would only prevent 549.9 metric tons of greenhouse gases all together. However, according to this chart, it would get rid of thousands of metric tons of greenhouse gases.
Explanation:
First, heat the solute to a high temperature, but not boiling. Next, dissolve the solute into the heated solution until the solute will no longer dissolve. Once that happens, take the heated solution off the heat and allow it to cool. Once the solution is cool you now have a supersaturated solution.
