Answer:
B: +3
Explanation:
If Gallium loses 3 electrons, it will become an ion.
The ion will be positively charged because in this new ion, the number of electrons is lesser than the number of protons. The charge difference will impart a positive net charge on the ion.
- In a neutral atom, the number of electrons and protons are the same.
- For positively charged ions, the number of protons is greater than the electrons
If Gallium the loss of 3 electrons offsets the charge balance in the chemical specie. Thus, the ion will have a net +3 charge.

Answer:
The correct answer is "5217 Cal".
Explanation:
The given values are:
Specific heat,
c = 3.76 cal/g°C
Mass,
m = 25.0 g
Initial temperature,
T₁ = 21.5°C
Final temperature,
T₂ = 77.0°C
Now,
The heat energy will be:
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
⇒ 
Answer: C
Explanation:
A. Shows 3-Hexyne (NOT 2-HEXYNE)
B. Shows 7 carbons (too many) (NOT 2-HEXYNE)
C. Shows a triple bond (yne) and 6 carbons and it's on the second carbon (2-HEXYNE)
D. Shows two substitent on the second carbon but the triple bond is on the 3rd carbon so it's 2,2-dimethyl-3-heptyne (NOT 2-HEXYNE)
According to research, the answer is no. Although alcohol is dissolves in water solution but dissociation of methyl alcohol in into ions is barely not possible. Thus, methanol is considered as a non-electrolyte.
