Answer:
(b) amino group
e) carboxyl group
Explanation:
The functional group in an organic compound distinguishes it from other compounds. It is usually the site where chemical reactions takes place.
CH₃-HC(NH₂)-COOH
There are two functional groups in this organic compoud:
- The NH₂ group is called the amino group
- The COOH is a carboxyl group
Answer:
the atmospheric temperature (varying according to pressure and humidity) below which water droplets begin to condense and dew can form. (60 degrees fahrenheit
Explanation:
The pH is calculated using the expression: pH = - log [H3O+].
To find the concentration of [H3O+]
[H3O+] = 10^(-pH)
Solving the RHS we have 10^(-4.240) = 0.1440
Hence the concentration of H3O+ is 0.1440.
Answer:
32.76mole of P
Explanation:
The reaction expression is given as;
P₄O₁₀ → 4P + 5O₂
Given parameters:
Number of moles of P₄O₁₀ = 8.19mol
Unknown:
Number of moles of P produced = ?
Solution:
From the balanced reaction expression;
1 mole of P₄O₁₀ will produce 4 mole of P
8.19mole of P₄O₁₀ will therefore produce 4 x 8.19 = 32.76mole of P
