It is part of oceans, air, rocks, soil and all living things. Carbon doesn't stay in one place. It is always on the move! In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide.
Hope this helps.
Answer:kapil
Explanation:
Atoms lose electrons, if an electron gets more energy than then binding energy of the electron. This may be because of a collision with a charged particle or because of absorbtion of a photon. In a metal, there are just other positive charges nearby. The electron is not lost, but shared.
Answer:
How many atoms are in 6.2 moles of aluminum? I mol = 6.02X1023 atoms so 6.2 mol = 6.2x (6.02x1025) = 3.73 x1024 atoms of Aluminum

Answer: Option (c) is the correct answer.
Explanation:
A state function is defined as the function of a system which relates to several state variables that depend only on the current equilibrium state of the system.
A state function does not depend on the path followed by the system to reach at its present state.
Enthalpy change is represented by
and its value depends on state functions like U, P and V. Therefore, change in enthalpy is also a state function.
Value of these functions does not depend on the path taken to reach their values.
Therefore, we can conclude that the statement enthalpy is a state function, is true.
