The correct option is False.
The first organic compound synthesized in the lab was urea. It was synthesized from silver cyanate and ammonium chloride. It is named Wöhler synthesis after the German chemist.
NH₄Cl + AgNCO → H₂NCONH₂
Urea was first synthesized in 1828 and its synthesis was the beginning of modern organic chemistry.
Part 1: If 1 mol = 6.022 x 10^23 atoms of anything, including Na, then,
4.0 mol Na = 4 x 6.022 x 10^23 atoms Na = 2.4 x 10^24 atoms Na
Part 2: 3.01E23 / 6.022E23 and the answer comes out to .49983394 you would then round this to .500 with significant figures. Hope I helped. :)
1=2.4*10^24 atoms NA
2= .49983394 round this to .500
Hope this helps!
Each carbon atom covalently bonds with atoms of carbon, hydrogen, oxygen, and nitrogen.
Each carbon atom ionically bonds with atoms of oxygen and nitrogen.
Each carbon atom covalently bonds with atoms of oxygen and nitrogen.
Each carbon atom covalently bonds with atoms of carbon, hydrogen, oxygen, and nitrogen describes why carbon can form a wide variety of organic compounds. thus, option B is correct.
Valency is the combining power of an element. Elements in the same group of the periodic table have the same valency. The valency of an element is related to how many electrons are in the outer shell.
Carbon can form a wide variety of organic compounds because Each carbon atom covalently bonds with atoms of carbon, hydrogen oxygen, and nitrogen. a carbon atom can have 4 single valence electrons around it. This allows it to form covalent bonds with many different atoms.

B. Electron pairs repelling each other push atoms apart
C. Valence electrons modify core electron orbitals
D. Intermolecular forces distort electron bonds
Answer:
B. Electron pairs repelling each other push atoms apart
Explanation:
The VESPR theory explains molecular shape by suggesting that electron pairs repelling each other push atoms apart.
If an atom is bonded to two or more other kinds of atoms as in many covalent molecules and ions, the shape of the system is determined by the geometry of the bonds around the central atom.
A candle placed between two plane mirrors inclined at an angle of 45 degrees will form 7 images. This is due to multiple reflections between the mirrors. The number of images depends on the angle between the mirrors.
In physics, when a candle is placed between two plane mirrors inclined at an angle of 45 degrees, 7 images will be formed. This happens due to multiple reflections between the mirrors. As per the formula for number of images n = 360/θ - 1, where θ is the angle between the mirrors, for an angle of 45 degrees, we get n = 360/45 - 1 = 7. The actual number of images can be less than this if they overlap each other.
