Write a balanced net ionic equation for each of the following aqueous metathesis reactions. Classify each reaction as a neutrali
melamori03 [73]

Answer:

See explanation

Explanation:

A. This is a neutralization reaction.

Molecular equation;

HBr(aq) + CsOH(aq) ---------> CsBr(aq) + H20(l)

Complete ionic equation;

H^+(aq) + Br^-(aq) + Cs^(aq) + OH^-(aq)   --------> Cs^+(aq) + Br^- + H20(l)

Net ionic equation;

H^+(aq) + OH^-(aq)   -------->  H20(l)

B. This is a gas forming reaction;

H2SO4(aq) + Na2CO3(aq) ------->Na2SO4(aq) + H2O(l) + CO2(g)

Complete ionic equation;

2H^+(aq) + SO4^-(aq) + 2Na^+(aq) + CO3^2-(aq)  ------->2Na^+(aq) + SO4^-(aq) + H2O(l) + CO2(g)

Net ionic equation;

2H^+(aq) + CO3^2-(aq)  -------> + H2O(l) + CO2(g)

C. This a precipitation reaction

Molecular equation;

CdCl2(aq) + Na2S(aq) ------->CdS(s) + 2NaCl(aq)

Complete ionic equation;

Cd^2+(aq) + 2Cl^-(aq) + 2Na^+(aq) + S^2-(aq) ---------> CdS(s) + 2Na^+(aq) +  2Cl^-(aq)

Net ionic equation;

Cd^2+(aq) +  S^2-(aq) ---------> CdS(s)

Calculate the mass percent of carbon in the hydrated form of the solid that has the formula BeC2O4•3H2O.
jeka94

Answer:

15.89%

Explanation:

To calculate the percentage of carbon in BeC2O4•3H2O, first we calculate the molar mass of BeC2O4•3H2O

MM of BeC2O4•3H2O = 9+(12x2)+(4x16)+3(2+16) = 9+24+64+54 =151g/mol

Mass of C in BeC2O4•3H2O = 2x12 = 24g

%Mass of carbon in BeC2O4•3H2O = (24/151) x 100

= 15.89%
