A compressed spring is the right answer
Answer:
Explanation: The total volume (rock plus water) in the graduated cylinder is 34 mL. We know the volume of water in the cylinder was 20 mL. Therefore, the volume of the rock must be 14 mL. Because a milliliter is exactly the same volume as a cubic centimeter, the volume of the rock is 14 cm3.
Explanation:
Image result for The unit of volume is mL. Make sure to check the units of graduation to get the most accurate reading possible
Graduated cylinders have numbers on the side that help you determine the volume. Volume is measured in units called liters or fractions of liters called milliliters (ml).
Answer:
a) 1.8 kJ
Explanation:
ΔG=-RtLnK
Just input the data into the equation to gives us the result, in Joules.
ΔG=-8.314*(25+273.15)*ln(0.48)
ΔG=1819,37 J
But there is only 2 significant figures, so we express it as or 1.8 kJ
Answer:
By making observations and doing experiments
No, an element is a pure substance, it cannot be broken down into simpler substances or be decomposed by chemical means.
