The compound FeCl3 is made of one atom and three atoms of chlorine
<u><em>explanation</em></u>
- FeCl3 is made up of two elements.
- that is iron with Fe chemical symbol and chlorine with Cl chemical symbol.
- There are 3 atoms of chlorine in FeCl3 because the subscript in front of Cl in FeCl3 is 3.
The possible number and location of all subatomic are one of them is electrically neutral, while the other has a stable electronic configuration.
<h3>What are subatomic particles?</h3>
Subatomic particles are those particles that are present inside the atoms. They are electron, neutron, and proton. They are charged particles, protons are positively charged, electrons are negatively charged and neutrons are neutral.
The protons and electrons totally contribute to the atomic mass of the elements.
Thus, the subatomic particles are electrically neutral and stable to electronic configurations.

<h3>
Answer:</h3>
1.93 g
<h3>
Explanation:</h3>
<u>We are given;</u>
The chemical equation;
2C₂H₆(g) + 7O₂(g) → 4CO₂(g) + 6H₂O(l) ΔH = -3120 kJ
We are required to calculate the mass of ethane that would produce 100 kJ of heat.
- 2 moles of ethane burns to produce 3120 Kilo joules of heat
Number of moles that will produce 100 kJ will be;
= (2 × 100 kJ) ÷ 3120 kJ)
= 0.0641 moles
- But, molar mass of ethane is 30.07 g/mol
Therefore;
Mass of ethane = 0.0641 moles × 30.07 g/mol
= 1.927 g
= 1.93 g
Thus, the mass of ethane that would produce 100 kJ of heat is 1.93 g
