612C
Explanation:
The correct answer is carbon-12: this is a nuclear fusion reaction.
In nuclear reactions, the mass number and the atomic numbers are usually conserved:
⁹₄Be + ⁴₂H ₙᵃX + ₀¹n
conserving atomic number:
4 + 2 = n + 0
n = 6
conserving mass number :
9+4 = a + 1
a = 12
therefore X = ¹²₆C

Answer:
physic
Explanation:
physical chnages are chnages to the appearance
chemical chnages are chnages like
color temperature chnaging fromna gas to a liquid etc
The series which is in order of increasing boiling point is CH3CH2CH3 CH3COCH3 CH2CH2CH3OH
However, the boiling point of an organic substance is the temperature at which the vapor pressure of the liquid organic substance equals the pressure surrounding the liquid and the liquid changes into a vapor.
<h3>What are organic compounds?</h3>
Organic compounds are substance containing carbon and hydrogen. Some few organic compounds include:
- Alkanes
- Alkenes
- Alkynes
- Alkanols
- Alkanals
- Alkanones
- Esters
- Amines
So therefore, the series which is in order of increasing boiling point is CH3CH2CH3 CH3COCH3 CH2CH2CH3OH

Answer:
Water acts as a base in the presence of a strong acid
Explanation:
Water,being an amphoteric compound, can act both as an acid and as a base.
In the presence of an acid , water acts as a base but in the presence of a base, water acts as an acid.
