The answer is.997 atm. 1. Identify the combined gas law equation... (P1V1/T1 = P2V2/T2) 2. Gather our values... P1=.982 atm P2=? (this is what we want to find) V1= 2 L V2= 1.8 L T1= 22 C = 295 K T2= -3 C = 270 K - Note: Always convert to Kelvin. To do this, add 273 to the Celsius value. 3. Rearranging the formula to suit this problem... (P2=P1V1T2/V2T1) 4. Insert our values... P2=.982 atm x 2 L x 270 K / 1.8 L x 295 K 5. Calculate and the result should yield....997 atm - If you require further clarification or assistance, feel free to reach out and I'll be happy to help!
The element you are looking for is Pb (Lead). Just check the last orbital on the periodic table to find it!
Answer:
The ratios arranged in ascending order are; The ratio of the mass of Y to X in XY2 divided by the mass of Y to X in XY, The ratio of the mass of Y to X in XY3 divided by the mass of Y to X in XY, The ratio of the mass of Y to X in XY4 divided by the mass of Y to X in XY
1) Mass ratio = 3
2) Mass ratio = 2
3) Mass ratio = 4
Explanation:
Comprehensive calculations are displayed in the attachment.
A skeletal formula is usually used for organic compounds
A indicates the power lines are what truly conducts (or transmits) the power.
Options B or E are incorrect, as wood is not a good conductor. That's why it's commonly used in homes to retain heat (which comes from electricity), preventing it from escaping.
Option C is also not correct since rubber, similarly, is a poor conductor. Like wood, it acts as an insulator, not transmitting heat (or electricity). This is why rubber gloves are utilized during electrical work.
Option D is valid—most metals are excellent electricity conductors. For instance, copper pans are efficient in cooking because copper effectively conducts heat. Being a metal, this is also why wire cutters have rubber grips; it isolates the user from potential electric shock from the conductive metal. The rubber serves as a barrier to protect against electrocution when handling wires or electricity.
