If the reaction is a chemical change, new substances with different properties and identities are formed. This may be indicated by the production of an odor, a change in color or energy, or the formation of a solid.
Answer:
3.43 * 10^23 atoms of zinc
Explanation:
According to Avogadro's law, one mole of a substance contains a certain number of atoms of the substance commonly referred to as the Avogadro's number.
We already know from Avogadro's law that;
1 mole of zinc contains 6.02 * 10^23 atoms of zinc
Therefore;
0.57 mole of zinc will contain 0.57 * 6.02 * 10^23/1
which gives us 3.43 * 10^23 atoms of zinc
Answer:
i think b is the answer hope this helps:))
Answer:The molecules in a raw egg absorb the heat energy, they use this energy to change shape
Such a chemical reaction is said to be endergonic, which means 'energy in'.
Egg molecules will never undergo these reactions without the input of energy (usually in the form of heat)
I hope this helps, if not, let me know :)
