Answer:
A. 1s²2s²
B. 1s²
C. 1s²
D. 1s²2s²2p⁶
Explanation:
The valency electron is the outer electron of an element. The valency electron resides in the outermost region of the shell.
Using the general configuration for the first 20 elements 2 8 8 2 the valency electrons can be identified.
A. 1s²2s²2p⁶3s² . The valency electron here are 2p⁶ and 3s² . Removing the valency electron we have 1s²2s²
B. 1s² 2s² 2p⁶. After removing the valency electron the configuration will be 1s².
C.1s²2s². After removing the valency electron the configuration will be 1s²
D.1s²2s²2p⁶3s¹. Removing the valency electron the electron configuration will be 1s²2s²2p⁶
Answer:
The answer is: higher temperature/ more kinetic energy/ more space between particles/ higher volume
Explanation:
Answer: This may result in the protein forming bonds with additional amino acids, this may result in the protein forming bonds with lipids instead of other proteins
Explanation:..
Answer:
C. Solubility
Explanation:
Solubility. A physical property does not change the chemical compostion. Solubility can be observed, unlike the others.
Answer:
4O₂ (g) + 1/2C₅H₁₂ (g) → 5/2CO₂ (g) + 3H₂O (g)
4 would be the smallest possible integer for O₂
Explanation:
The balanced equation is this one:
8O₂ (g) + C₅H₁₂ (g) → 5CO₂ (g) + 6H₂O (g)
If we divide stoichiometry /2 (the half) we can consider that we use, the smallest possible integers.
8/2O₂ (g) + 1/2C₅H₁₂ (g) → 5/2CO₂ (g) + 6/2H₂O (g)
4O₂ (g) + 1/2C₅H₁₂ (g) → 5/2CO₂ (g) + 3H₂O (g)
