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)

A saturated solution of calcium hydroxide contains 1.85 g of solute in 100. mL of solution. What is its molarity
Leona [35]

Answer:

M=0.250M

Explanation:

Hello!

In this case, since the molarity of a solution is computed by dividing the moles of solute by the volume of solution in liters, we first need to compute the moles of solute knowing that the molar mass of calcium hydroxide is 74.1 g/mol as follows:

n=1.85g*\frac{1mol}{74.1g}=0.0250mol

Next, since the 100-mL solution is also expressed in liters by 0.100 L, we directly compute the molarity as shown below:

M=\frac{0.0250mol}{0.100L}\\\\M=0.250M

Which is expressed in molar units that are mol/L.

Best regards!

A weather balloon holds 2,000 cubic meters of helium. The density of helium is 0. 1765 kilograms per cubic meter. How many kilog
Paraphin [41]

Answer:

353kg

Explanation:

2000 x 0.1765 = 353kg

for every 1 cubic metre of helium there is 0.1765 kg of it

the balloon is holding 2,000 cubic metres of the helium.

That means that there are 2000 times of 0.1765kg of helium in the balloon

so you times 0.1765kg by 2000
