<span>2, 4 its the answer hope it helps</span>
<span>Xe = VIII = 8 valence electrons
F = VII = 4 (7 ve) = 28 valence electrons</span>
total ve = 8 + 28 = 36 ve
<span>36 - 4(2) = 28 ve
(there are 2 electrons in each bond x 4 bonds)</span>
<span>28 - 4(6) = 4
(We assign the remaining electrons to F atoms)</span>
<span>4 - 2(2) = 0
(Therefore 4 electrons left => we have 2 lone pairs)</span>
The steric number = No. of
σ bonds + #lone pairs
= 4 σ bonds + 2 lone pairs
= 6 => d²sp³ (6 hybrid orbitals)
<span>4 bonds + 2 lone pairs
=> square planar</span>
Given parameters:
duration of fall = 6s
Unknown:
Speed of the rock before it hits the ground = ?
Solution:
To solve this problem, we apply one of the appropriate motion equations;
V = u + gt
Where V is the final velocity
u is the initial velocity
t is the time taken
g is the acceleration due to gravity = 9.8m/s²
The initial velocity is 0;
So;
V = gt
Input the parameters and solve for V;
V = 9.8 x 6 = 58.8m/s
The velocity before hitting the ground is 58.8m/s
To be fair, you have to have a very high IQ to understand Rick and Morty. The humour is extremely subtle, and without a solid grasp of theoretical physics most of the jokes will go over a typical viewer's head. There's also Rick's nihilistic outlook, which is deftly woven into his characterisation- his personal philosophy draws heavily from Narodnaya Volya literature, for instance. The fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these jokes, to realise that they're not just funny- they say something deep about LIFE. As a consequence people who dislike Rick & Morty truly ARE idiots- of course they wouldn't appreciate, for instance, the humour in Rick's existential catchphrase "Wubba Lubba Dub Dub," which itself is a cryptic reference to Turgenev's Russian epic Fathers and Sons. I'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as Dan Harmon's genius wit unfolds itself on their television screens. What fools.. how I pity them.
And yes, by the way, i DO have a Rick & Morty tattoo. And no, you cannot see it. It's for the ladies' eyes only- and even then they have to demonstrate that they're within 5 IQ points of my own (preferably lower) beforehand. Nothin personnel kid
<h3><u>Answer:</u></h3>
When hot magma cools, igneous rocks are formed.
b) When graphite is under higher pressure and heat, it becomes diamond.
c) Igneous rocks include pumice and granite and can be formed above Eath's surface.
d) Metamorphic rocks are formed when existing rocks are changed inside Earth.
<h3><u>Explanation:</u></h3>
Magma is the molten rocks that is found inside Earth’s surface. Its the lava that is stored inside the Earth’s surface. This magma formes out of the Earth's surface during a volcanic eruption, or cools inside the Earth's surface itself to form igneous rock.
Graphite and diamond both are the allotropes of carbon. This is the change in allotropes which can occur in extreme cases of temperatures or pressure which can occur inside the Earth’s surface. This can change graphite to diamond.
Igneous rocks which are externally formed are pumice or basalt which forms when lava comes out of Earth's interior and cools to form rock. Whereas the Igneous rocks like granite are formed when the magma cools inside the Earth’s surface due to cooling of lava.
Metamorphic rocks are formed when the Igneous or sedimentary rocks undergoes conditions of severe temperature or pressure from inside the Earth's surface and the structure of the rock fully changes. This is how the metamorphic rocks form.
