A solution of silver chlorate reacts with a solution of lithium iodide.
Anettt [7]

Answer: Ag^+(aq)+I^-(aq)\rightarrow AgI(s)

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.  

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The given chemical equation is:

AgClO_3(aq)+LiI(aq)\rightarrow AgI(s)+LiClO_3(aq)

The complete ionic equation is:

Ag^+(aq)+ClO_3^-(aq)+Li^+(aq)+I^-(aq)\rightarrow AgI(s)+Li^+(aq)+ClO_3^-(aq)

The ions which are present on both the sides of the equation are lithium and chlorate ions. and hence are not involved in net ionic equation.

Thus the net ionic equation is:

Ag^+(aq)+I^-(aq)\rightarrow AgI(s)

Answers only please 100pts and brainliest. you will be reported for wrong answers.
Ierofanga [76]

Answer:

K= 25.16%

Mn= 34.59%

O= 40.25%

Explanation:

KMnO_4

Find the total mass of the compound. You can do this by multiplying by the molar mass.

K=40*1=40\\Mn=55*1=55\\O=16*4=64

add them:

40+55+64=159g

Now convert each element individually to grams using molar mass

1molK(\frac{40gK}{1molK} )=40gK

1molMn(\frac{55gMn}{1molMn} )=55gMn

4molO(\frac{16gO}{1molO})=64gO

Divide by the mass of the compound and multiply by 100

K=\frac{40g}{159g} *100=25.16

Mn=\frac{55g}{159g}*100=34.59

O=\frac{64g}{159g}*100=40.25

How many moles are in 120g of NH3
Simora [160]

Moles of NH₃ : = 7.059

<h3>Further explanation</h3>

Given

120 g NH₃

Required

moles NH₃

Solution

The mole is the number of particles contained in a substance

<em>1 mol = 6.02.10²³ </em>

Moles can also be determined from the amount of substance mass and its molar mass

Mol = mass : Molar mass

So for 120 g (molar mass of NH₃ = 17 g/mol) :

= 120 g : 17 g/mol

= 7.059
