Answer:
The correct option is this: DECREASING THE TEMPERATURE.
Explanation:
During the process of chemical reaction, the reacting molecules typically move about randomly in the reacting vessels colliding with one another and with the wall of the container. The rate of movement of the reacting particles can be reduced by decreasing the temperature of the reaction. If the temperature is reduced, the particles will lose kinetic energy and thus, they will move more slowly and collide less often with one another.
The correct answer is B... the should be divided into these to groups.
solid or liquid
Answer:I believe it’s because of the volcanos making up the ring
Explanation:
First, we determine the number of moles of gas present using the ideal gas equation.
PV = nRT
n = PV / RT
n = (1.4 * 226.4) / (0.082 *(27 + 273.15))
n = 12.88
Next, we use the given percentages to find the moles of helium present
Moles of helium = 0.655 * 12.88
Moles of helium = 8.44
Next, we use the formula:
Mass = moles * molar mass
Mass of helium = 8.44 * 4
Mass of helium = 33.76 grams
Density=mass/volume
density=45/26.4
density=1.7g/ml
