Here's what I get
Explanation:
The Lewis structure of SO₃ consists of a central sulfur atom double-bonded to each of three oxygen atoms that points to the corners of an equilateral triangle.
A ball-and-stick model of SO₃ is shown below.
Explanation:
Kinetic energy is defined as the energy obtained by an object due to its motion. Whereas energy obtained by an object due to its position is known as potential energy.
(a) When a sled is resting at the top of a hill then it means the sled in not moving. Hence, then it has only potential energy. But when a sled sliding down the hill then it is moving from its initial position.
Hence, when a sled is sliding down the hill then it has higher kinetic energy.
(b) When water is above the dam then it only has potential energy but when the water falls over the dam then it has higher kinetic energy.
Answer:
Look at your periodic table
Explanation:
It tells you everything like Potasium 1 and 1 ox and 1 hydrogen
Answer: last option, what came before the big bang?
Explanation:
The big bang theory states that the universe started as a dense nucleus of matter: a huge amount of matter concentrated in a tiny spot.
This is the conclusion of equations and evidences that prove that the universe has been and continuous to expand: since it has been expanding, there was a moment when it was as small and dense as it is possible.
So, the expansion is the result of violent explosion.
The time during which the expansion has been happening (this is how long ago the big bang occured) has been estimated thanks the the observation of the speed of recesion of the galaxies, but nothing can be told about what came before the bing bang occured.
