The sum of the coefficients in the balanced chemical equation for combustion of acetone C3H6O in air is 11
explanation
<h2>
write a balanced chemical equation for reaction</h2>
that is; C3H6O + 4O2 → 3CO2 +3H2O
coefficient is the number in front of the chemical formula
the sum of coefficient is therefore= 1 ( in front of C3H6O) + 4 ( in front of O2) + 3 ( in front of CO2) + 3 ( in front of H2O) = 11
Answer: this is your answer 26.3 kJ/1 mol Fe2O3 (s) – 3.40 mol Fe2O3

Answer: The addition of salt in ice particles causes a decrease on its freezing point.
Explanation: salt definitely lowers the freezing point of ice particles.
Explanation:
The species with a positive charge over it, which means lack of electrons are called cations. Whereas the species with negative over it, meaning it has an excess of electrons with it are called anions.
From the list given the cations are
H+, Ba2+, Hg2+, Li+, Ca2+ and Fe2+
Whereas anions from the list are
O-2, Br-5, F-, S-2.
A Combination of cation and anions make an ionic compound in which cation is written first and then anion.
