Answer:
substance
Explanation:
I think it is a substance
i think..
potassium hydroxide..
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.
You will have 0.06502087426717999 moles of NaCl with 3.8 grams. 1 gram= 0.0171107563861
Answer:
The coefficient with water is 6.
Explanation:
Chemical equation:
NH₃ + O₂ → NO + H₂O
Balanced chemical equation:
4NH₃ + 5O₂ → 4NO + 6H₂O
When ammonia and oxygen react nitric oxide and water produced.
Nitric oxide is gas and decompose in air.
The coefficient with water is 6 and equation is correctly balanced.
There are four nitrogen atoms, twelve hydrogen atoms and ten oxygen atoms on both side of equation.
Coefficients with reactant and product:
NH₃ 4
O₂ 5
NO 4
H₂O 6
