Answer:
True
Explanation:
I guessed XD But I also used Google and that's what I got
Known :
r = 6 in
h = 11 in
Asked :
Volume = ...?
Answer :
V = πr²h
= 3.14 × 6² × 11
= 3.14 × 36 × 11
= 3.14 × 396
= <u>1</u><u>,</u><u>2</u><u>4</u><u>3</u><u>.</u><u>4</u><u>4</u><u> </u><u>in³</u>
So, the volume is 1,243.44 in³ (2nd choice)

The Periodic Law
Dmitri Mendeleev developed own periodic law with atomic number as the basis for the arrangement. The Periodic Law, also known as "Mendeleev's Law" states, " When elements are arranged in order of increasing atomic mass, certain sets of properties recur periodically." It also describes the properties of the elements as periodic functions of their atomic weights.
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:
The reactión is exothermic
Explanation:
The change in enthalpy follow the next equation:
ΔH = ΔH(products) - ΔH(reactants)
If the products have a lower enthalpy means that ΔH<0; this mean that the reaction gives heat to the environment
