The coloured gas is

Which part of dalton's atomic theory was disproved by further scientific research?

How does the volume of an ideal gas at constant pressure change as the temperature increases?

You have 4.872 x 1034 atoms of Copper. How many moles is this?

if 1200 j of heat were absorbed by a 25 g block of iron, by how much would the temperature of the iron increase?

A. no color change was observed indicating that changing temperature does not affect equilibrium. b. increasing the temperature changes the solution to blue indicating that the equilibrium shifts to the left and decreasing the temperature changes

When 10 liters of a gas at 1 atm is compressed to 3 liters at constant temperature, what property of the gas changes?

Will mark branliest. Calculating percent yield: For the reaction Cu + 2AgNO3 → Cu (NO3) 2 + 2 Ag, adding 127 grams of copper to lots of silver nitrate yields 410 grams of silver. What is the percent yield of silver? I'm desperate.
