Answer:
no
Explanation:
Fluoride is not nucleophilic (having the tendency to donate electrons) enough to allow for the use of HF to cleave ethers in protic media(protic solvents are polar liquid compounds that have dissociable hydrogen atoms). The rate of reaction is comparably low, so that heating of the reaction mixture is required.
Answer:
116 Cal
Explanation:
15 g CHO × 4 Cal/g = 60 Cal
5 g PRO × 4 Cal/g = 20
4 g fat × 9 Cal/g = <u> 36 </u>
TOTAL = 116 Cal
There are 116 Cal in one serving of the product.
Answer:
Comprehensive Two-dimensional gas chromatography, or GCxGC is a multidimensional gas
Boyles law is P1V1=P2V2 where P is pressure and V is volume so the answer is pressure and volume
Answer:
¹⁶⁸₇₉Au
Explanation:
The symbol of the atom is given as;
¹⁷²₈₁Tl
If undergoes a nuclear reaction and it ejects an alpha particle;
An alpha particle is the same as an helium atom
¹⁷²₈₁Tl → ₂⁴H + ₐᵇK
K is the hypothetical symbol of the new atom
b is the new mass number
a is the new atomic number;
Conserving mass number;
172 = 4 + b
b = 172 - 4 = 168
Conserving atomic number;
81 = 2 + a
81 - 2 = a
a = 79
The new compound is gold with a symbol of;
¹⁶⁸₇₉Au
