The outermost electrons of the atom are either lost or gained by one of the atoms to the other. therefore the atom gains negative charge when gaining and positive charge when losing
We are given the following data.amount of oxygen gas mixed=108 grams molar mass of oxygen gas 32 g/mol volume of c3h8ch8.
Vanadium (V)
Vanadium is the only one in the 4th period here so
Answer:
KOH(aq) + HCl(aq) ——-> KCl(aq) + H2O(l)
Explanation:
A neutralization reaction is the chemical reaction between an acid and an alkali to yield salt and water only.
In this particular question, the acid is hydrochloric acid while the alkali is potassium solution. We now write the equation of reaction as follows:
KOH(aq) + HCl(aq) ——-> KCl(aq) + H2O(l)
The salt formed here is KCl otherwise called potassium chloride
<u>Answer:</u> Electron has almost no mass.
<u>Explanation:</u>
Mass is defined as the actual matter that is contained in a substance. At an atomic level, it is expressed in atomic mass units.
The given options are the 3 subatomic particles.
Mass of the given subatomic particles are:
Proton = 1.007276u
Neutron = 1.008664u
Electron = 0.0005485u
Mass of neutron is slightly more than the mass of proton.
From the above information, it is visible that electron has a negligible mass.
Hence, the correct answer is electron.
