In the lab a substance is studied and the following observations are made. At room temperature (20 °C) the substance has the following properties: 1. It is a solid that is shiny and silver in color. 2. It has a density of 1.738 g/mL. 3. It is malleable (it can be pounded into a flat sheet). 4. It is ductile (it can be pulled into a thin wire). 5. It is a good electrical conductor. The substance is subjected to some further experiments and these additional observations are made. 6. It melts at 649 °C. 7. It boils at 1105 °C. 8. It burns in air, glowing with an intense white light. 9. It reacts with bromine to give a brittle white solid. Which of these characteristics are physical properties, and which are chemical properties?

Pls help me with the following. I don’t really get it why is it wrong. Make sure your answer is correct 100% and explain thanks
Gold can be hammered into extremely thin sheets called gold leaf. A 200-mg piece of gold (density = 19.32 g/cm3) is hammered into a sheet measuring 2.4 ft x 1.0 ft. %3D What is the average thickness of the sheet in meters? Hints: Calculate the volume of the sheet from its density and mass, and then use the volume relationship for a rectangular solid, V = length x width x thickness.

Need help with this textbook question thats been giving me hard time. Please show steps. calculate x to the correct number of significant figures: Should be in standard notation or scientific notation. ln(3.86 / 1.00) = 362.8 x 10^3 / 8.314 (((298.1)^-1) - x^-1) Here are choices: 300.9 301 3.0 x 102 300.88 300.8
I need the answer as soon as possible
I don't understand the wording. The least significant digit means the last digit? 7.700 X 2.1 = 16.17 would the uncertainty be 0.01 ? 2.132 + 17 + 4.04 = 23.172 would the uncertainty be 0.001 ?
