Answer:
I'm so sorry I would love to help you but I have no idea
Idk about 1, but for 2a: saturated means that all carbons have the maximum amount of hydrogens attached to them, and unsaturated means that they don’t. Only alkanes are saturated because they have all single bonds, so they have the max amt of hydrogens bonded to the carbons. 2b: saturated: butane, octane, methane. Unsaturated: ethene, butene.
The balanced chemical reaction is written as:
<span>Cu +2AgNO3 → Cu(NO3)2 + 2Ag

We are given the amount of silver nitrate to be used for the reaction. This value will be the starting point of our calculations. It is as follows:
4.00 g AgNO3 ( 1 mol / 169.87 g ) ( 1 mol Cu / 2 mol AgNO3 ) ( 63.456 g / 1 mol ) = 0.747 g Cu
Answer:
O2 is a covalent substance while NaCl is an ionic substance
Explanation:
In O2 molecule, the bond is between 2 oxygen atoms which are non - metals. Thus, this is a covalent bond since it involves 2 non metals.
Whereas, for the NaCl molecule, the bond is between a metal sodium (Na) and a non metal Chloride(Cl) and thus we can say this is an ionic bond.
Thus the difference is that O2 is a covalent substance while NaCl is an ionic substance.
A teratogen is an exposure (substance, organism or process) in pregnancy that has a harmful effect on the fetus. Teratogens can be diseases, medications, drugs and environmental exposures.
