Explanation:
15) The both diamonds- the diamond used as a grinding tool and the two -carat diamond both have the same density because density is an intensive or intrinsic property of a substance. It does not depend on the mass of the substance present.
16) Area of magnesium = Length * width = 0.104 * 10^2 cm * 2.52 * 10^-1 cm = 2.62 cm^2
Density = mass/area * thickness
Density * area * thickness = mass
thickness = mass/Density * area
thickness = 0.104 g/ 1.74g/cm3 * 2.62 cm^2
thickness = 0.0228 cm
Answer:To solve for time, divide the distance traveled by the rate. For example, if Cole drives his car 45 km per hour and travels a total of 225 km, then he traveled for 225/45 = 5 hours.
Explanation:
<span>The combined gas equation relates three variables pressure, temperature and volume when the number of moles is constant.
The equation is PV / T = constant. Which is valid for a fixed number of moles of the gas.
You can derive the combined gas equation from the combination of Bolye's law, Charles' law and Gay-Lussac's law, which needs some algebra.
Answer: option 2. number of moles.
