Explanation:
cause potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.
Gasses contain highly energetic particles which tend to spread out to fill the room/ container they are in. Often when a smell rises, there is a high concentration of gas molecules in the rising smell. Here diffusion occurs where the molecules spread out randomly moving from an area of high concentration of gas molecules to areas of low gas molecules.
Answer:
0.80 Moles of Hydrochloric Acid would be required to produce 0.40 Moles of hydrogen gas due to the equation ratios
Explanation:
How many moles of hydrochloric acid are required to produce .40 moles of hydrogen gas?
Hydrochloric acid = HCl
Hydrogen gas = H2
H = 1+
Cl = 1-
HCL = H2 + Cl2
2HCl = H2 + Cl2
2:1:1
0.80 = 0.40 + 0.40
Answer A
