Answer:
B. Ca(OH)2(s)+CO2(aq)-CaCO3(s)+H2O(aq)
<span>1mole of Cl atoms contain the Avogadro's number 6x10 exp 23(10 to the power of 23)
there for xmoles of Cl atoms is contained in 1.72x1022atoms
xmoles =1.72x1022 divided by 6x10exp 23
2.93 exp -23moles(2.93 x10 to the power of -23)
Hope It helped Let me know if did!!!!

Answer:
Because: The mixtures contain unwanted substances which may be harmful and may degrade the properties of mixtures. So we, need to separated them and extract useful substances.
Answer:
A carbon–carbon bond is a covalent bond between two carbon atoms.
Explanation:
The diatomic molecule with a triple covalent bond is N2.
Nitrogen has five atoms in its valence shell. In order for it to attain the octet structure, that is, to have eight electrons in its outermost shell, it has to donate three electrons, just like the other element it is reacting with in order to form a triple covalent bond.
