The element Sodium will
form a +1 cation, while the bromine a -1 anion. Since the anion bromine is
always a liquid, therefore its symbol is Br2(l). So, the chemical equation for
their reaction is: <span>
<span>2Na(s) + Br2(l) -> 2NaBr(aq) </span></span>

The question is incomplete, the complete question is;
The lightest particle among the following is:
• Electron •Proton • Neutron • Alpha
Answer:
Electron
Explanation:
There three basic subatomic particles are electrons, protons and neutrons. Both protons and neutrons are found in the nuclear and both contribute towards the mass of the atom. The alpha particle has the same mass as the helium nucleus.
However, the electrons are found in orbiit and have a negligible mass compared to the mass of the protons and neutrons. The mass of the electron is about 9.11 × 10^-31 Kg. This makes it the lightest of all the particles listed among the options.
2C₃H₇OH + 9O₂ = 6CO₂ + 8H₂O
a₀=2
a₁=9
a₂=6
a₃=8
the correct answer is option d.
