Answer:
Bond angle is affected by the presence or addition of lone pair of electrons at the central atom. Due to this, the bonds are displaced slightly inside resulting in a decrease of bond angle, and when you remove an electron domain the bond angle increases.
Explanation:
You take the temperature and follow these steps:
Take the temperature in farenheit, suntract 32, then multiply that by 5, and divide by 9.
The substances which will exist in molecular form in solution are-
A. CH₃NH₂
D. CH₃OH
The methyl amine (CH₃NH₂) and methanol (CH₃OH) is organic compounds which are hardly become ionic in nature and prefers to form as molecular state in the solution phase.
On the other hand B. LiOH and C. NH₄OH are inorganic compound and highly ionic in nature and remain as ionic state in solution.
Those are-
LiOH (s) → Li⁺(s) + OH⁻ (s)
NH₄OH→ NH₄⁺ (s) + OH⁻ (s)
Answer:
You can increase your precision in the lab by paying close attention to detail, using equipment properly and increasing your sample size. Ensure that your equipment is properly calibrated, functioning, clean and ready to use.
