The following molecular equation represents the reaction that occurs when aqueous solutions of silver nitrate and aluminum chloride are combined. 3 agno3(aq) + alcl3(aq) 3 agcl(s) + al(no3)3(aq) write the balanced net ionic equation for the reaction.

3Ag^(+) + 3Cl ^(-) --> 3AgCl (s)

Explanation:

Full ionic equation:

3Ag^(+) + 3NO3^(-) + Al^(+3) + 3Cl^(-)-->

3AgCl (s) + Al^(3+) + 3NO3^(-)

Spectator ions 3NO3^(-) & Al^(+3) can be left out in the net ionic equation.

hi,

the capital city of australia is canberra.

when 25.0 ml of 0.700 mol/l naoh was mixed in a calorimeter with 25.0 ml of 0.700 mol/l hcl, both initially at 20.0 °c, the temperature increased to 22.1 °c. the heat capacity of the calorimeter is 279 j/°c.

the equation for the reaction is:

naoh + hcl → nacl + h₂o

moles of hcl = 0.0250 l hcl ×

0.700

mol hcl

1 l hcl = 0.0175 mol hcl

volume of solution = (25.0 + 25.0) ml = 50.0 ml

mass of solution = 50.0 ml soln ×

1.00

ml soln

= 50.0 g soln

δt=t2-t1

= (22.1 – 20.0) °c = 2.1 °c

the heats involved are

heat from neutralization + heat to warm solution + heat to warm calorimeter = 0

q1+q2+q3=0

nδh+mcδt+cδt=0
