Chemical reactions happen by them self like if you hear baking soda and it makes a gas.
<span>We can use rocks to determine if the animals from to day have changed from the past.
Rocks also help us know if rivers once flowed through an area.
We use them to find out what type of animals live then that are extinct now.</span>
Answer:
Density = mass / volume,
therefore volume = mass / density. Note that 1 mL = 1 cubic centimeter.
Explanation:
Volume = 15.1g / 3.52g/mL = 4.3mL = 4.3 cubic centimeters.
then a diamond has a density of 3.52 g/mL.
The total volume of water that would be removed will be 75 mL
<h3>Dilution equation</h3>
Using the dilution equation:
M1V1 = M2V2
In this case, M1 = 500 mL, V1 = 10.20 M, M2 = 12 M
Substitute:
V2 = 500 x 10.20/12
= 425 mL
The final volume in order to arrive at 12 M HNO3 would be 425 mL from the initial 500 mL. Thus, the total amount of water that will be removed by evaporation can be calculated as:
500 - 425 = 75 mL
