The elements in each group have<span> the </span>same<span> number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (</span>group<span> one) </span>has<span> one electron in its outer shell.</span>
When you burn a log in your fireplace you are converting c<span>ellulose into carbon dioxide and water.

Wood is made from cellulose. When wood burns, cellulose reacts with oxygen from the air and it forms carbon dioxide and water vapor.
The reaction of the combustion of glucose is as follows:
C₆H₁₂O₆ + 6O₂ = 6 CO₂ + 6H₂O
When wood burns, we notice that it slowly disappears because it passes into the mentioned gases. The ash that is created is part of the wood that did not burn.
the Orange side will grow higher bc people on the blue side will eventually become over 65
Answer:
Stretching vibration, and
Bending vibration (Rocking, wagging, Twisting and Scissoring)
Explanation:
- Stretching vibration: this causes change in the length of a bond
- Bending vibration: this causes change in the angle between two bonds
Bending vibration can occur as rocking, wagging, twisting and Scissoring vibration
2a) Rocking vibration: this causes change in angle between group of the atoms
2b) Wagging vibration: this causes change in angle between the plane of a group of atoms
2c) Twisting vibration: this causes change in the angle between the planes of two groups of atoms.
2d) Scissoring vibration: this causes the movement of two atoms toward and away from each other
