Answer: air
Explanation:since individual components of air cannot be identified by merely looking at it, it is a homogeneous mixture.
Answer:
The number of moles of Fe in 1.17*10^22 atoms Fe is 0.0194 moles
Explanation:
Step 1: Data given
Number of atoms of Fe = 1.17 * 10^22 atoms
Number of Avogadro = 6.022 *10^23
Step 2: Calculate number of moles Fe
Moles Fe = atoms Fe / number of Avogadro
Moles Fe = 1.17*10^22 atoms / 6.022*10^23 / moles
Moles Fe = 0.0194 moles
The number of moles of Fe in 1.17*10^22 atoms Fe is 0.0194 moles
No, it won't change the amount of reactants nor the products as a catalyst will only provide an alternative path where lower activation energy is needed for the process to take place.
hope this explains it
If it does, please give it a brainliest :)))
Answer:
Surface tension
Capillary action
Explanation:
Surface tension is the force acting along the surface of the liquid causing the liquid surface to behave like a stretched elastic skin. Surface tension causes the water drops that fall on a smooth surface to form rounded drops or beads.
If you touch a piece of paper to the drop, water appears to move up into the paper on its own due to capillarity. Capillarity is the tendency of a liquid to rise or fall in a narrow tube.
