Answer is: 1. HClO₃; (chloric acid).
Balance chemical reaction (dissociation):
ClO₃⁻(aq) + H₂O(l) ⇄ HClO₃(aq) + OH⁻(aq).
According
to Bronsted-Lowry theory acid are donor of protons and bases
are acceptors of protons (the hydrogen cation or H⁺).
The chlorate anion (ClO₃⁻) is Bronsted base and it
can accept proton and become conjugate acid HClO₃..
Answer: Neutron found at B. electron found at A. proton found at B
It is usually measured on the Pauling scale, on which the most electronegative element (fluorine) is assigned an electronegativity of 4.0. Each of these elements has a low electronegativity on the Pauling scale, and the electronegativities clearly decrease down the group.
Answer:
3.79 moles
Explanation:
To convert moles to gams of a substance we need to find the molar mass of the substance. For Ca(OH)₂ th molar mass is:
1Ca = 40.08g/mol
2O = 2*16g/mol = 32g/mol
2H = 2*1.01g/mol = 2.02g/mol
The molar mass is:
40.08g/mol + 32g/mol + 2.02g/mol = <em>74.1g/mol</em>
<em />
And moles are:
281g * (1mol / 74.1g) =
<h3>3.79 moles</h3>
