Answer:
smallest particle of an element which can take part in a chemical reaction
Explanation:
there are atoms of different elements is sodium atom
Answer: 
Explanation:
Given
Mass of iron piece is 
Heat absorbed 
Temperature changes from 
i.e.
Heat absorbed is given by ![Q=mc\Delta T\quad [c=\text{specific heat of material}]](https://tex.z-dn.net/?f=Q%3Dmc%5CDelta%20T%5Cquad%20%5Bc%3D%5Ctext%7Bspecific%20heat%20of%20material%7D%5D)
Insert the values
Thus, the specific heat of iron is
Your answer would be D you welcome !
Answer is: concentration of products increases (ammonia nad water).
Chemical reaction: heat + NH₄⁺ + OH⁻ ⇄ NH₃ + H₂<span>O.
</span>According to Le
Chatelier's Principle, the position of equilibrium moves to counteract the
change, because heat is increased, system consume that heat, so equilibrium is shifted to right, by decreasing concentration of reaactants and increasing concentration of product.
