Answer:
σ*2pₓ, also called 
Explanation:
I have drawn the MO diagram for fluorine below.
Each F atom contributes seven valence electrons, so we fill the MOs of fluorine with 14 electrons.
We have filled the 
and 
MOs.
They are the highest occupied molecular orbitals (HOMOs).
The next unfilled level (the LUMO) is the σ*2pₓ orbital. If you use the symmetry notation, it is called the orbital.
This is the orbital that fluorine uses when it acts as an electron acceptor.
Answer:
O a 2 in front of hydrochloric acid
Explanation:
the given reaction is :-
=》Zn + 2 HCL -> ZnCl2 + H2
since, mass can't be created or destroy, so number of hydrogen atoms in the reaction should be equal in product as in reaction.
so, there is 2 hydrogen in product hence there are two hydrogen in the reactants also.
it is showed in the reaction by putting a 2 in front of hydrochloric acid ( HCl ).
M has lost an electron.
It's oxidation.
Length: The most common units that we use to measure length in the metric system are the millimeter, centimeter, meter, and kilometer. The millimeter is the smallest commonly used unit in the metric system
Mass: Kilogram.
Liquid volume: The basis of fluid volume units for the metric system is the liter. A liter is about the same as one quart.
- The independent variable in an experiment is the variable whose value the scientist systematically changes in order to see what effect the changes have.
- A dependent variable is what the experimenter observes to find the effect of systematically varying the independent variable.
- Experimental constants are values that do not change either during or between experiments.
- A controlled variable is a variable that could change, but that the experimenter intentionally keeps constant in order to more clearly isolate the relationship between the independent variable and the dependent variable.
(And psa. don't lie to people about the points earned!)
CO2(s) is a solid.
CO2(g) means it is gas.
So they differ in their physical properties.
Physical propertiers means that they differ in their look.
